5 Action on Loss of Power Stays in place. Action on Loss of Input Signal (Power On) Stays in place or moves to full travel or zero position. Drives to any preset position with optional switch assembly on Models 11-__7 and 11-__8. Field adjustable. Stall Protection and Annunciation (Optional) If the motor tries to run in one direction for more than 300 seconds, the Stall Protection Module will shut off power to the motor and a solid state relay will change state. The relay is rated for 120 V ac or dc, 10 VA. Limit Switches Two SPDT, one for CW and one for CCW limit of travel. Actuators having position sensing capability (Options 5 thru 8), have over- travel limit switches set 1/2° outside the CW and CCW travel range (typically, -0.5° and 100.5° or 90.5°). Actuators without position sensing (Options 3 and 4), have end-of-travel limit switches set at the CW and CCW travel range (typically, 0° and 100° or 90°). Auxiliary Switches Up to four 6 A, 120 V ac (0.5 A, 125 V dc) switches available. Switches are labeled S1-S4 and are cam-operated, field-adjustable. S1 and S4 are set to operate just before reaching the CCW travel limit. S2 and S3 are set to operate just before reaching the CW travel limit. Handswitch Permits local electrical operation, independent of controller signal. Standard on all units. An auxiliary contact is available as an option for remote auto indication (rated 2.5 A at 120 V ac; 2.0 A at 28 V dc). Handwheel Provides manual operation without electrical power. Motor Assembly 120 V ac, single-phase, no-burnout, non-coasting motor has instant magnetic braking. Requires no contacts or moving parts. Can remain stalled for approx. 4 days (cumulative) without damaging the gear train. Gear Train High-efficiency, precision-cut, heat-treated alloy steel and ductile iron spur gears. Interchangeable gear modules permit field change of torque and timing. Mechanical Stops Prevent overtravel during automatic or manual operation. Enclosure Precision-machined, aluminum alloy castings coated with corrosion-resistant polyurethane paint, provide a rugged, dust-tight, weatherproof enclosure. Actuators designed for hazardous classified locations are also available. Type 4X; IP66/IP68, 3 meters/48 hours*. *Internal water damage is not covered by warranty. Maximum Output Shaft Rotation 100 degrees (Models 11-15_, 11-20_, 11-30_, 11-40_) 90 degrees (Models 11-16_, 11-26_, 11-36_, 11-46_) Mounting Orientation Any orientation—no limitations.

STORAGE INFORMATION Beck actuators should be stored in a clean, dry area where the temperature is between -40° and 85°C (-40° to 185°F). Damage due to moisture while in storage is not covered by warranty. INSTALLATION—MECHANICAL There are many considerations regarding proper mechanical installation—see the instructions beginning on page 16 for details. Refer to the outline dimension drawings for physical dimensions and required clearances. VALVE ACTUATOR INSTALLATIONS CAUTION Working with valves installed in a pipeline can be dangerous. Take appropriate precautions when mounting to installed valves. INSTALLATION—ELECTRICAL See the instructions beginning on page 19 for details regarding electrical installation. CAUTION For maximum safety, the Beck actuator body should be grounded. Use the green grounding screw in the wiring compartment of the actuator. CAUTION Always close covers immediately after installation or service to prevent moisture or other foreign matter from entering the actuator. PRECAUTIONARY INFORMATION

16 INSTALLATION—MECHANICAL Beck Group 11 actuators may be installed in any convenient orientation, because the gearing does not require an oil bath. Refer to the outline dimension drawings for physical dimensions and required clearances. VALVE ACTUATOR INSTALLATIONS CAUTION Working with valves installed in a pipeline can be dangerous. Take appropriate precautions when mounting to installed valves. Whenever an actuator is being mounted on a valve, refer to the valve manufacturer's maintenance manual for specific valve-related instructions. Consult the Beck Valve Mounting Specification sheet shipped with the actuator for specific instructions on assembly of the Beck actuator and mounting hardware to the valve. It is good practice to remove the valve from service if possible. UNITIZED VALVE/ACTUATOR ASSEMBLY INSTALLATION Inspect the valve and pipe flanges to ensure they are clean. Be certain that other pipelines in the area are free from pipe scale or welding slag that could damage the gasket surfaces. Carefully lift the assembly and position the valve in the pipeline. Install and tighten the flange bolts according to the valve and/or gasket manufacturer’s instructions. NOTE: The valve may have undergone temperature variations in shipment. This could result in seepage past the stem seals. Refer to the valve manufacturer’s maintenance instructions for packing adjustments, if required. FOOT MOUNTED ACTUATOR INSTALLATIONS Actuators may be mounted in any orientation. If mounting near obstructions such as pipes or beams, take into consideration access to the field wiring terminals, enclosure cover clearances, and the output shaft. Refer to the outline dimension drawings for the clearance necessary to remove covers. Before the actuator is bolted into place, the mounting surface must be shimmed for flatness to within 0.020 inches. Each shim must support at least 75% of the mounting foot surface area (recommended shim size is 4 square inches or larger). Improper shimming or mounting can damage the actuator mounting feet. If the actuator is to be bolted to a mounting plate, the plate must be rigid and must not yield to the stresses created from operating the actuator. If the mounting plate is not rigid or the mounting bolts are not sufficiently tightened, damage to the actuator housing could result. A rigid, vibration- free surface will generally prolong the life of the actuator’s components. The mounting plate should be at least as thick as the diameter of the mounting bolts. Mounting bolts should be hex head steel, zinc plated (HHSZP) Grade 2 or better and sized as shown in the table below. The bolts should be torqued appropriately for the application. Actuator Model Bolt Size Bolt Torque 11-15_ 3/8" 20 lb-ft (27 N•m) 11-20_ / 11-30_ 5/8" 100 lb-ft (135 N•m) 11-40_ 3/4" 175 lb-ft (237 N•m) MOUNTING PEDESTALS Standard and custom retrofit Beck pedestals are available, including designs for a number of common pneumatic actuators such as the Bailey AC and UP series and Hagan cylinders. A typical generic pedestal is shown here. INSTALLATION Mechanical

17 LINKAGE REQUIREMENTS (IF APPLICABLE) For best results, the linkage should be designed in advance. In most applications, the best control will result when the linkage is adjusted so that the full 100° travel of the Beck actuator shaft is used, even though the actuatorn lever may travel less than 100°. The general requirements for a good linkage are: 1. It must be rigid enough to carry the link thrust without bending or deforming. 2. It must have a built-in means of adjustment so that the length of the connecting link can be changed a small amount. 3. Rod end bearings, similar to those furnished on the Beck crank arm, should be used at both ends of the connecting link. This type of device permits small angular misalignments and helps prevent binding of the linkage. 4. The Beck crank arm radius must be calculated so that the arm will move through a 100° arc and the actuatorn lever will move through its correct arc. 5. The actuator and driven shafts must be parallel and the linkage should be in a plane perpendicular to the shafts. See the example of a parallel linkage arrangement at right. Z-Linkage arrangements (where linkage ends are on opposite sides of the parallel between the actuatorn shaft and actuator output shaft) are not recommended. LINK-ASSIST™ REPORT The Beck Link-Assist™ computer program optimizes the linkage configuration for the application load. It ensures proper setup and operation of the actuator. Contact your Beck Sales Engineer to take advantage of Beck’s Link-Assist™ program. Additional Link-Assist™ information is available on the Beck website: www.haroldbeck.com.

18 LINKAGE KITS AVAILABLE Beck linkage kits are made to accommodate a wide variation in linkage lengths without requiring modification of end fittings. Hex Linkage kits are available for applications with linkage length requirements between 9" (229 mm) and 26" (660 mm). Each hex linkage kit comes complete with a rod end, studs, threaded hex bar, and jam nut hardware. To order hex linkage kits, first obtain the approximate overall linkage length “A” in the hex linkage figure above. Select the kit part number from the table on the left. For lengths beyond those listed in the table, contact your Beck sales engineer. Pipe linkage kits are available for longer linkage length requirements and include the essential linkage end connections, rod end, studs, and jam nut hardware. Schedule 40 pipe is not included and must be cut to length and threaded in the field (see table above, for instructions to calculate pipe length). To simplify installation of the pipe link, the kit accepts NPT right-hand threads on both ends of the pipe. Left-hand threads are internal to the linkage kit assembly, making final length adjustments quick and easy. To order pipe linkage kits, first obtain the approximate overall linkage length “A” in the figure above. Select the kit part number from the table above. For lengths beyond those listed in the table, contact your Beck sales engineer.

19 LINKAGE INSTALLATION The following procedure is recommended to couple the linkage between the Group 11 actuator and the actuatorn shaft: 1. Position the actuatorn shaft  to the fully closed position. 2. Set the actuatorn shaft lever to its required starting angle  (predetermined with Link- Assist™). 3. Remove the rod end  from the Beck crank arm. Attach to the connecting link. 4. Adjust the connecting link  to the predetermined length. 5. Connect the connecting link to the actuatorn lever at the predetermined radius . 6. Set the crank pin (or rod end screw on 11-15_, see appropriate outline dimension drawing) on the Beck crank arm to the predetermined radius. This is done by loosening the crank pin screws  and sliding the crank pin to the predetermined position (none on 11-15_). Tighten the crank pin screws to the appropriate torque. 7. Loosen the crank arm clamping screws . CAUTION The crank arm will pop free, allowing adjustment for 360° around the shaft. 8. Position the actuator’s output shaft  to its fully closed limit. 9. Swing the crank arm into position and assemble the connecting link to the crank arm crank pin. Tighten the rod end nut  to the appropriate torque (see table next page). 10.Tighten the crank arm screws  evenly, in a cross-pattern (if applicable), to the appropriate torque (see outline dimension tables beginning on page 6). 11.Lubricate the rod end bearings. Carefully move the actuator’s output shaft to the fully open (maximum Demand signal) position. Check that no binding occurs between the linkage, crank arm, driven shaft lever, and surrounding obstructions. Also observe that the actuatorn shaft rotates the proper amount. Ensure that the actuator reaches the proper limit and shuts off. If binding in the linkage occurs due to too much travel of the actuatorn lever, travel can be reduced by shortening the Beck actuator crank arm radius. Return the actuator to the fully closed position. Loosen the crank arm crank pin screws, and the linkage stud-coupling lock nuts. To make fine length adjustments, while rotating the linkage move the crank pin to a shorter radius position. To adjust the linkage length, it is preferable to use the stud couplings. The couplings have right- hand and left-hand threads, so it is not necessary to disconnect the ends to make a length adjustment. Be careful not to expose more than 7” (178 mm) of stud between the rod end and coupling. CAUTION The thread engagement depth in the couplings and rod ends must be greater than 1.25 x the thread diameter. Tighten crank pin screws and linkage lock nuts, and once again, check operation to confirm that no binding occurs between the linkage and crank arm, driven lever arm, or surrounding obstructions. Further travel adjustments can be made by repeating the above steps. Tighten all lock nuts and screws to the specified torque value (see outline dimension tables). Do not change limit switch settings to obtain desired valve or damper travel; this will adversely affect actuator operation. LINKAGE INSTALLATION 4 10 8 2 0 6 6 0 2 8 10 4 1 3 6 8 2 5 4 7 9

20 POWER QUALITY Power quality disturbances such as power outages, transient voltages, harmonic distortions, and electrical noise will adversely affect your actuator performance. Protecting your actuator from these conditions can reduce downtime and promote longer life for the equipment. Following the industry accepted standards below will help protect your actuator. a Select wiring materials according to the correct ampacity ratings dictated by national and local regulations. a Shielded, twisted pair cables can be used for signal connections to avoid being affected by electrical noise. These signal wires, based on Noise Susceptibility Level (NSL) per IEEE-518, fall into the level 1 classification. A braided shield will be more effective than a wrapped foil shield. Signal wire shields should be connected to the actuator casting grounding screw. If grounding at the signal source is required, then the shield should not be grounded at the actuator. a Raceways such as conduits and trays must be grounded at both ends to properly meet immunity requirements. a An AC power ground connection should be made between the power source and the Beck actuator. Grounding connections including wire and metal conduit are permitted, but the actuator-grounding conductor may not be connected to a structured metal frame of a building. a Surge suppression equipment that meets Underwriters Laboratory (UL) Standard 1449 may be used to protect against transient voltage conditions. a Power Conditioners may be used to regulate the supply voltage and maintain a constant voltage level. They are helpful in protection against voltage sags and swells, as well as some measure of electrical noise protection. a Harmonic filters may be used to minimize the effects of supply voltage waveform distortions and are used in applications that incur a large amount of high-frequency electronic noise. CAUTION Always close covers immediately after installation or service to prevent moisture or other foreign matter from entering the actuator. ELECTRICAL INSTALLATION Two 1” N.P.T. conduit connections are provided for power and signal wiring to the actuator. A sealant must be used on threaded conduit connections to keep moisture out. Conduits should be routed from below the actuator so that condensation and other contaminants entering the conduit cannot enter the actuator. Power and signal wires should be routed to the actuator separately and be either shielded cables or installed in conductive conduit and/or cable trays. Refer to the wiring diagram furnished with your Beck actuator for proper AC power and signal connections. The customer must supply 120 V ac to power the actuator (standard configuration). The 120 V ac line connects to terminal C and neutral to terminal B. Other available power options include 208, 240, 380, 415, 480 & 575 V ac. It is advisable to provide normal short circuit protection on the AC power line. A copy of the wiring diagram is shipped with each actuator and is fastened to the inside of the terminal block cover. If there is no wiring diagram available, you may obtain a copy from Beck by providing the serial number of your actuator. Connection of a 4-20 mA Demand signal should be made to terminals AA (+) and BB (–). For maximum safety, the Beck actuator body should be grounded. Use the green grounding screw in the wiring compartment of the actuator. TERMINAL SCREW TORQUES Each terminal screw should be torqued to the proper specification upon landing the wire.

INSTALLATION Electrical

21 The terminal block is located in a separate, gasketed compartment at the top of the actuator. Line voltage connections are made on terminal designations A through V and are oriented at a right angle from the low voltage signaling terminals designated AA through EE. Actuators equipped with optional transformers to accommodate popular voltages include an additional terminal strip and fuse for power wiring (with the exception of the 240 volt option). See optional transformer wiring connections at right. Terminal screws will accept standard spade or ring terminals, as well as bare wire. Terminals A through V are size #8, and terminals AA through EE are size #6. Optional transformer terminal screws (designated 1, 2, & 3) are size #10 for all models except 11-1__ which are #8. All terminals on all actuators will accept up to #12 AWG (3.31 mm2) with one exception. Actuator models 11-2__, 11-3__ and 11-4__ may use up to #10 AWG wire on the optional transformer terminals (1–3). Typical wiring connections for each control option are shown below and on the following page. Each actuator can be ordered with up to four optional auxiliary switches (wiring connections are described in the Configuration/Calibration section). Customer must supply two wires to power the actuator: One 120 V ac line (terminal C), and one neutral (terminal B). Customer must supply two wires for the modulating analog control signal: Connect to terminal AA (+) and to terminal BB(-). Customer may supply two additional wires to monitor the analog position feedback signal (see pages 23 and 24 for connections). The actuator’s feedback circuit power supply is derived from the 120 V ac line, so the feedback signal must be wired to a “4-wire” type non-powered analog input. Customer must supply two wires to power the actuator: One 120 V ac line (terminal C), and one neutral (terminal B). Customer must supply two wires for the modulating analog control signal: Connect to terminal AA (+) and to terminal BB (-). If position feedback monitoring is required, an optional auxiliary potentiometer can be ordered. The optional auxiliary potentiometer connects to terminals CC (reverse), DD (wiper), and EE (forward) and is compatible with standard “slidewire” style inputs. Option 8, Modulating Analog Position Control with Contactless Position Sensing Option 7, Modulating Analog Position Control with Potentiometer Position Sensing INSTALLATION Wiring To prevent Handswitch initiated motion, remove jumper (JA) from between terminals A and C. CAUTION AC power to the actuator must be turned off before removing the jumper (JA). FUSE (F1) 1 2 3 Three additional terminals and fuse (F1) are provided with 3-phase power options.

22 INSTALLATION Wiring Customer must supply three wires to directly control the actuator motor direction: One 120 V ac line to run CW (terminal M), one 120 V ac line to run CCW (terminal N), and one neutral (terminal B). Customer may supply two additional wires to monitor the analog position feedback signal. If position feedback monitoring is desired, a 120 V ac line must be connected to terminal C. The actuator’s feedback circuit power supply is derived from this 120 V ac line, therefore the feedback signal must be wired to a “4-wire” type, non-powered analog input. Customer must supply three wires to directly control the actuator motor direction: One 120 V ac line to run CW (terminal M), one 120 V ac line to run CCW (terminal N), and one neutral (terminal B). The position feedback potentiometer connections are available at terminals CC (reverse), DD (wiper), and EE (forward). Customer must supply three wires to directly control the actuator motor direction: One 120 V ac line to run CW (terminal M), one 120 V ac line to run CCW (terminal N), and one neutral (terminal B). Up to six intermediate stop positions may be specified, each requiring an additional 120 V ac line. Customer must supply three wires to directly control the actuator motor direction: One 120 V ac line to run CW (terminal M), one 120 V ac line to run CCW (terminal N), and one neutral (terminal B).

23 CPS-5 POSITION FEEDBACK SIGNAL CONNECTIONS Beck actuators equipped with the Contactless Position Sensor (CPS-5) are shipped ready for installation to match the proper mA or V dc feedback range in your system. Customer connections for feedback signal wiring on each CPS-5 model are described in the following diagrams and paragraphs. Refer to page 61 for information on output signal ranges, output terminals, range-changing resistance values, and terminals to which the ranging resistor or jumper is connected. NOTE: For output shaft rotation of less than 80°, refer to Calibration Procedure, page 36. To verify that the feedback signal range is correct for your actuator, see the instructions on page 36. NOTE: Ranging resistors must be connected to the actuator output terminals. If ranging resistor change is required, use a resistor with ±1% tolerance. Resistors can be ordered from Beck. CPS-5 Model 20-4400-02, -12 Terminal Connections 1. A single 4–20 mA current output is available between terminals EE (+) and CC (-) when driving into an external load between 250 and 800 ohms.

24 INSTALLATION Wiring CPS-5 Model 20-4400-03, -13 Voltage Feedback Terminal Connections The universal model has a voltage divider network which allows for various voltage signal ranges. Voltage output ranges are available across terminals EE (+) and CC (-) with the proper ranging resistor connected across terminals CC and DD. Units are factory-calibrated for specified signal ranges and are provided with proper ranging resistors installed. Other voltage ranges are attainable by adding a ranging resistor across terminals CC and DD. CPS-5 Model 20-4400-04, -14 Terminal Connections The three-terminal output from these models is provided for replacing potentiometers in three- terminal potentiometer feedback applications used in many controllers. It is suitable for 0 –15 V dc applications of either positive or negative polarity. CC must be connected to the negative lead from the controller, and EE to the positive lead from the controller, with DD connected to the controller lead accepting the feedback from the potentiometer wiper. These models can “source” 10 mA to the controller, or they can “sink” 2.5 mA from the controller. CPS-5 Model 20-4400-05, -15 Terminal Connections Voltage signal -10 to +10 V dc is available across terminals EE (+) and DD (-). The maximum load is 5 mA. Voltage Output Potentiometer Equivalent The ranging resistor value is given on page 61, or can be calculated using the equation: Where R = Resistor Connected from CC to DD V = Output Voltage Span If converting to a zero-based range (a range that includes zero as an end point), refer to “Adjusting the zero potentiometer”, page 38. CPS-5 Model 20-4400-03, -13 Current Feedback Terminal Connections The universal model has current sensing terminals, which allow for various current signal ranges. Current output is available between terminals DD (+) and CC (-) with the proper ranging resistor connected across terminals DD and EE. Units are factory-calibrated for specified signal ranges and are provided with proper resistors installed. The ranging resistor value is given in the table on page 61, or can be calculated using the following equation: Where R = Resistor (Ohms) Connected from DD to EE I = Output Current Span (Amp) If converting to a zero-based range (a range that includes zero as an end point), refer to “Adjusting the zero potentiometer”, page 38. Current Output 4 R = Ω (I – .004)

25 INPUT SIGNAL OPTIONS Beck actuators configured for milliamp or DC analog modulating applications include an Electronic Signal Receiver (ESR-5) board. Several control options are available with the ESR-5, such as operating more than one actuator with a single signal source. The instructions below apply to applications which require a signal change or to situations calling for operation of multiple actuators from a common demand Demand signal. Input Range Change to ESR-5 If it is necessary to change the Demand signal range, jumpers must be removed (and, in one case, a resistor added) as per the table below. See the figure on page 41 for component locations. Series Operation Beck actuators can be connected in series from the same signal for concurrent operation. Care must be taken to keep the polarity correct in each actuator’s input terminals. Two or three actuators may usually be connected in series. The number of actuators that may be connected in series is limited only by the controller’s (signal source) capability to feed current into the total resistance of the circuit involved. Consult the controller manufacturer’s recommendations. No change is required to the actuator calibration for series operation. An interruption in the circuit will actuate loss of Demand signal (L.O.S.) on the actuators in the circuit. Parallel Operation Beck actuators can be connected in parallel to the same Demand signal for concurrent operation. Up to four actuators may be connected in parallel. For parallel operation on a 4–20 mA Demand signal, use ESR-5 board no. 13-2246-05 in each actuator and add a resistor across input terminals AA and BB on one of the Beck actuators. The resistor value* should be as follows: 2 actuators = 261Ω resistor 3 actuators = 270Ω resistor 4 actuators = 280Ω resistor *Resistor values will vary for other Demand signals, please consult the factory. Note that a minor span adjustment is required for each actuator in parallel. An interruption in the circuit to one actuator will not prevent the other actuators from functioning, but there will be a slight calibration shift. ESR-5 MODELS* INPUT SIGNAL ESR-5 PART NO.

26 INSTALLATION Wiring Split Range Operation Two or three Beck actuators may be operated over their full range by a portion of the controller’s output signal range. The most common arrangement involves the parallel operation of two actuators operating on equal halves of the Demand signal range. See the following example: If a 4–20 mA control signal is used, the first actuator would move 100% of its stroke on a signal range of 4–12 mA, while the second operates on the 12–20 mA portion of the signal. In this case, the ESR-5 boards are the same as would be used for parallel operation (13-2246-05), but calibrated to the range required for each actuator. A resistor must be added across input terminals AA and BB on one of the Beck actuators to produce a span between 2 and 6 volts across each board for its active portion of the range; for this example, use a 487Ω resistor.* Follow the steps for calibrating the Demand signal, page 38, for each actuator unit, using half span values for the Demand signal. Use the proper starting point for each half-range when setting the zero; 4 mA and 12 mA. Before setting the zero on the second actuator (12 mA), cut R35. See the figure on page 41 for its location on the board. When three actuators are to be operated on equal portions of the Demand signal, the 4–20 mA range would split into 4–9.33 mA, 9.33–14.67 mA, and 14.67–20 mA signals. A 487Ω resistor* may be used. Proceed as in the case of the 2-way split, first setting the span, then the zero. When setting the ESR-5 board in the first actuator, set the zero at 4 mA. Then, on the second actuator cut R35 and set its zero at 9.33 mA. Before setting zero in the board of the third actuator, short out R34 by adding a jumper, adjust its zero at 14.67 mA, cut resistors R35 & R36, then remove the jumper from R34. Check operation of all actuators by running the Demand signal through its complete range. In a split range configuration, connect terminals E and F (L.O.S. wire) to prevent undesired “stay-in-place” operation of the second and, if applicable, third actuator due to fast downward signal changes. *Resistor values will vary for other Demand signals, please consult the factory.

27 START-UP NOTE: All Beck actuators are shipped from the factory ready for installation. Each actuator is set-up and calibrated to the customer’s specifications that were written into the equipment order. Electrical adjustments are generally not required before placing the actuator in operation. START-UP INSTRUCTIONS After the actuator is mounted and its wiring connections are made, it is ready to be tested for proper operation. Turn on the power supply. Operate the actuator with the Handswitch and run it through its full stroke, both directions. Observe that the actuatorn device travels through its desired stroke. If satisfactory, set Handswitch to the “AUTO” position. If the actuator is to be operated with automatic control, turn on the controller and operate the actuator by varying the control signal. Check that the damper or valve strokes in the proper direction for a change in control signal. If it does not, first check for proper wiring connections and verify control signal at the actuator. If the wiring is correct, then change the direction of output shaft rotation (see page 33). If the actuator is to be push-button actuated, (options 3, 4, 5, or 6) operate the actuator using the Handswitch and observe that direction of travel is correct. When travel of the actuatorn device is satisfactory with reference to the control signal or the push-buttons, the unit is ready for operation.

28 OPERATION HOUSING Beck electric actuators have individual cast aluminum compartments for each of the five main components: The control motor, wiring terminal block, drive train, electronic signal receiver, and control end. Gasketed covers and sealed shafts make the actuators ideally suited to outdoor and high humidity environments. Heavy cast mechanical stops built into the housing are designed to prevent accidental over- travel damage during manual cycling, and ensure that proper orientation is maintained be tween the output shaft and the feedback system. CONTROL MOTOR The Beck control motor is a synchronous inductor motor which operates at a constant speed of 72 RPM or 120 RPM in synchronism with the line frequency. Motors are able to reach full speed within 25 milliseconds and stop within 20 milliseconds; actual starting and stopping times will vary with load. Beck motors have double grease-sealed bearings and require no maintenance for the life of the motor. GEAR TRAIN The gear train is a four-stage reduction, spur gear drive constructed with only heat-treated alloy steel and ductile iron gears for durability and long life. The actuator train consists of the control motor and Handwheel, reduction gears, main gear, output shaft, and crank arm. The main gear / output shaft and third stage gears are common to all units of a particular actuator model. The second and first stage gears are part of the field-interchangeable gear module. Different combinations of gear modules and actuator motors determine the actuator’s output torque and timing. See table on page 56 for details. On standard models, the output shaft is limited by mechanical stops to 108° of rotation (98º on the 11-160). Optional main gear / output shaft assemblies are available that permit multi- revolution output rotation. Mechanical stops are not included on these models. Mechanical transmission of output shaft position to the control end is provided by a right angle gear set driven directly by the output shaft. SELF-LOCKING MECHANISM (SLM) An integral part of every control motor is the self-locking mechanism. This mechanical device couples the motor to the gear train and transmits full motor torque when rotated in either direction. When the motor is de-energized, the SLM instantaneously locks and holds the output shaft in position. HANDWHEEL Every Beck actuator is furnished with a Handwheel to permit manual operation of the valve or damper without electrical power. Its solid construction design includes no spokes or projections, and turns at a safe, slow speed. The Handwheel is located at the rear of the control motor housing. The Handwheel is coupled directly to the motor shaft and rotates when the motor runs. Manual operation of the Handwheel (with electric Handswitch in “STOP” position) turns the motor and the rest of the actuator train without incorporating a clutch. HANDSWITCH A local electric Handswitch is provided on Beck actuators to permit operation at the valve or damper, indepen dent of the controller. As a safety feature, the Handswitch is designed so that the controller can operate the actuator only when it is in the “AUTO” position. The sequence of the Handswitch is: “AUTO”, “STOP”, “CW”, “STOP”, “CCW”. In the “AUTO” position, two contacts are closed and the ESR-5 or external controller contact completes the control circuit. In the “CW” or “CCW” positions, contacts are closed to operate the actuator independently of the controller. In the “STOP” position, all contacts remain open. SWITCHES Two over-travel limit switches (control options 5 thru 8) or two end-of-travel limit switches (control options 3 and 4) and up to four optional auxiliary switches are provided on Beck actuators. Switch cams are clamped onto the control shaft which rotates in relation to the output shaft. Cam position is field-adjustable. Switches are rated 6 A, 120 V ac. All auxiliary switch connections are made on the terminal block.

29 CONTROL OPTIONS Two basic types of control are available: 120 V ac contact closure (options 3, 4, 5, and 6) and milliamp or DC analog modulating (options 7 and 8). Each option is described below. Open / close option 3: For simple 2-position control using manual push-buttons or an automatic controller. Preset end-of-travel limit switches provide open / close operation upon closure of an automatic controller or manually operated switch. Travel limits are adjustable over the full range of travel and provide precise positioning repeatability. Multi-position option 4: Adjustable cam operated switches provide up to six discrete stop positions upon closure of an automatic controller or manually operated switch. Three, four, five, and six predetermined position settings are possible, with precise positioning repeatability. Direct AC control option 5: Provides continuous positioning capability over the full range of actuator travel by direct AC control from either an automatic controller or manually operated switches. Includes a 1,000 ohm film potentiometer for remote feedback. Direct AC control option 6: Provides continuous positioning capability over the full range of actuator travel by direct AC control from either an automatic controller or manually operated switches. Includes a Contactless Position Sensor (CPS-5) for feedback and position indication. Modulating option 7: For automatic operation in response to milliamp or dc analog control; includes a film potentiometer for position sensing and feedback to the Electronic Signal Receiver (ESR-5). Modulating option 8: For automatic operation, as in option 7 above; includes Contactless Position Sensor (CPS-5) for position sensing and feedback to the ESR-5. INPUT: ELECTRONIC SIGNAL RECEIVER (ESR-5) Beck modulating actuators are equipped with a precision electronic control module (ESR-5) to receive conventional 4–20 mA or 1–5 V dc control signals directly, eliminating the need for contact protection devices, relays, switches, and reversing starters. The ESR-5 provides control with either analog or microprocessor control systems, and is designed to operate continuously in temperatures up to 185°F (85°C). The ESR-5 requires a position feedback signal from either the CPS-5 monitor / isolator board or a film potentiometer. This feedback signal is compared to the Demand signal. A difference in these signals (the error) is amplified and used to actuate either of two electronic motor power switches. These switches drive the motor in the proper direction to force the error to zero. The Demand signal is adjustable from 50% to 400% of the 4-volt span, with the zero adjustable from -100% to +275% of span. The ESR-5 permits two or more Beck actuators to be operated by a single signal source, for series, parallel, or split range operation. See page 25 for details on these control options. If the Demand signal to the Beck actuator is changed, the ESR-5 allows for easy modification to accept a different signal current. An optional “Relay board” version of the ESR-5 permits operation on low current 120 V ac with an external diode / resistor module or low voltage DC Demand signals (5 to 24 V dc). This topic is covered on page 42. POSITION FEEDBACK: CONTACTLESS POSITION SENSOR (CPS-5) The CPS-5 provides a continuous feedback signal proportional to the position of the actuator’s output shaft. The position sensing function of the CPS-5 is provided by a ferrite magnetic sensing element. An electronic circuit translates the signal from the ferrite magnetic sensor into an analog position feedback signal designed to interface with elec tronic control systems and indicating instruments. When used with the ESR-5, the CPS-5 includes a monitor / isolator board that delivers an isolated position feedback signal to the ESR-5. The Monitor function monitors the CPS-5 position signal and compares it to established limits. If the output exceeds normal signal conditions, the monitor relay contact opens. This relay may be used for either a remote signal indication or activation of Loss-of-Signal operation of the actuator. POSITION FEEDBACK: FILM POTENTIOMETER The film potentiometer produces a voltage that is a fraction of the voltage applied across its resistive element. That voltage fraction is determined by the position of the wiper on the resistive element. The potentiometer assembly also includes two fixed resistors, one on each end of the resistive element. These resistors permit suppressed ranges as well as zero-based position feedback voltages. If position feedback is desired on actuators equipped with an ESR-5 board, two film potentiometers are required: One for position feedback and the second to supply a feedback signal to the ESR-5.

30 OPERATION CALIBRATION LOSS OF SIGNAL (L.O.S.) Beck actuators equipped with the ESR-5 have the ability to move to a predetermined position upon loss of demand signal. When the demand signal drops to approx. 13% of span below the zero setting, the ESR-5 provides an annunciating signal with one of the following options: 1. STALOS = Stay in place, lock in last position. (Triac output available at terminal E for remote alarm, 0.12 to 5 A, 120 V, 50 or 60 hz) 2. REVLOS = Move to the minimum limit switch position. Connect terminal E to F. 3. FWDLOS = Move to the maximum limit switch position. Connect terminal E to D. 4. INTLOS = Move to predetermined intermediate auxiliary switch position. Consult factory. When the demand signal is lost but the power remains on, the L.O.S. switch on the ESR-5 board is energized, a red LED on the board lights and the directional switches are turned off. The output of the L.O.S. switch is connected to terminal E which is wired for one of the predetermined operating modes listed above. When REVLOS, FWDLOS, or INTLOS is selected, an additional relay is required in order to provide the annunciating signal. This should be specified on ordering. STALL PROTECTION AND ANNUNCIATION The Beck Stall Protection Module (SPM) is an optional feature for Group 11 actuators. The SPM monitors the motor current at terminals N and M. The SPM will be activated when the actuator cannot reach a desired position within approximately 300 seconds. When a stall is sensed, the SPM shuts off power to the motor and a solid state relay in the SPM changes state. The relay is rated for 120 V ac or dc, 10 VA. Two terminals connected to the solid state relay are located on the SPM. Use of the relay for annunciation of a stall is optional and will not affect the other functions of the SPM. A sensed stall condition is cleared by either reversing the motor direction command in the controller or by turning the actuator power off and on. An LED is included on the SPM to show the operating status of the module. CALIBRATION PRIORITY Standard Group 11 actuators are equipped with fixed, non-adjustable, built-in mechanical stops. All output shaft rotation must occur within these stops, which are outside the electrical range of travel. The over-travel or end-of-travel limit switches are used to limit the electrical control range of the actuator. These switches are cam operated and are set slightly wider apart then the actuator’s intended full range of electronic operation for options 5 thru 8—typically 101° (11-15_/-20_/- 30_/-40_) or 91° (11-16_/-26_/-36_/-46_). For options 3 & 4, the end-of-travel limit switches are set at the actuator's intended full range of operation—typically 100° (11-15_/-20_/-30_/-40_) or 90° (11-16_/-26_/-36_/-46_). If the actuator is short-stroked—i.e., the full travel rotation from 0–100% is reduced to less than the standard 100° or 90° rotation—it may be desirable to reset the limit switches (see page 31). If the limit switches are not reset, Handswitch operation of the actuator (CW, CCW) will still result in the original full range of travel. It is best to calibrate the actuator and then set the limit switches when short-stroking the actuator. Over-travel limit switches (options 5 thru 8) should be set just outside the calibrated range to avoid tripping the switch at the 0% and 100% positions. The auxiliary switches are also cam operated, but have no affect on actuator operation. Therefore, the auxiliary switches can be adjusted at any time without affecting performance or calibration.

31 NOTE: Your Beck actuator was shipped from the factory ready for installation; no electrical adjustments are required before placing it in operation. Each actuator is set up and calibrated to the specifications that were written into the equipment order. Under normal operating conditions there is no need to recalibrate the actuator. However, if the application requirements change—or are different than specified on the equipment order—the actuator should be recalibrated according to the following procedures. SWITCH ADJUSTMENTS Over-travel limit switches (options 5 thru 8) are factory set 1/2° outside each end of travel unless otherwise specified at time of order. End-of-travel limit switches (options 3 & 4) are factory set at each end of travel unless otherwise specified at time of order. Limit switches must be set inside the range of the built-in mechanical stops to prevent stalling of the motor. Limit switches can be reset to limit travel of the output shaft to any angle down to a minimum of approximately 60°. Auxiliary switches are set as shown in the illustration on page 32 unless otherwise specified at time of order. NOTE: The limit switches are the switches closest to the actuator body. To adjust these switches, it is necessary to remove the control end cover. Switches are operated by cams which are clamped onto the control shaft. Setting a switch involves loosening the cam, moving the output shaft to the desired position, and positioning the cam so that it just operates the switch at that point. In the following procedure, the use of a continuity meter is recommended to determine when the switch opens or closes. If such a meter is not available, it is possible to hear the switch click as the contacts open and close. CAUTION Do not attach the meter or attempt to move the switch cams until the actuator is disconnected from the line voltage and auxiliary switches are disconnected from external power sources. SETTING LIMIT SWITCHES CW AND CCW This procedure should be used if the factory limit switch settings must be changed in the field. It is advisable to operate the actuator fully in each direction, using the electric Handswitch to check switch settings before attempting to change them. Follow these instructions if they require adjustment: NOTE: The rotation direction of the output shaft is the same as the control shaft except for models 11-1__, in which the shafts rotate in opposite directions. 1. Remove the control end cover (and extensions, if applicable) and terminal block cover (1/2” wrench). 2. Use the electric Handswitch to drive the control shaft so that the CW switch cam screw is accessible. Using a 7/64” hex wrench, loosen the screw so that the cam is just snug on the shaft (see photo, page 32). 3. Move the output shaft to the desired CW limit (for options 5 thru 8, this should be just outside the desired fully CW position). 4. Turn the Handswitch to the “STOP” position. 5. Disconnect power from the actuator. 6. Connect a continuity meter across terminals B and U. Rotate the cam until the meter shows no continuity (switch contacts open, switch clicks). 7. Tighten the cam locking screw to 5 Ib-in (0.56 N•m) torque. 8. Disconnect meter and ensure the Handswitch is in the “STOP” position. 9. Reconnect actuator power. 10. Rotate the actuator’s output shaft in the CCW direction away from the CW travel limit. Note the direction of rotation on the lobe of the cam. The correct cam lobe motion is away from the switch lever with the switch lever on the lower part of the cam. If not correct, return to step 2 and reset the cam to the proper orientation. 11. Rotate the output shaft again to the desired CW travel limit. If the stopping point is reached, the switch is properly set. 12. Repeat instructions 2–11 for setting the CCW limit switch (CCW rather than CW). Connect continuity meter across terminals B and V. 13. Replace covers and tighten cover bolts to 10 Ib-ft (14 N•m) torque. 14. Rotate index (or index pointer on models 11-1__) to correspond with output shaft rotation. CALIBRATION Switches

32 SETTING AUXILIARY SWITCHES Standard switch settings for actuators with 2 or 4 auxiliary switches are shown on the following diagram “Standard Limit and Auxiliary Switch Settings”. The heavy line indicates a closed circuit. Follow these instructions to change the operating point of auxiliary switches: NOTE: In the following procedure, it is assumed that switch settings are to be adjusted so that contacts are open when the desired position is achieved. If they are to be adjusted to close, it may be necessary to reverse the operating mode of the switch by reversing the leads on the switch itself. Be sure to disconnect power from the switch terminals first. 1. Remove the control end cover (and extensions, if applicable) and the terminal block cover (1/2” wrench). 2. Use the electric Handswitch to drive the shaft so that the switch cam is accessible. Using a 7/64” hex wrench, loosen the screw so that the cam is just snug on the shaft. 3. Move the output shaft to the desired switch trip position. 4. Turn the Handswitch to the “STOP” position. 5. Disconnect power from the actuator and switch terminals. 6. Connect the continuity meter across the appropriate terminals. See the specific actuator wiring diagram under the terminal block cover (or the generic diagram at right). Rotate the cam to operate the switch. 7. Tighten the cam locking screw to 5 Ib-in (1 N•m) torque. 8. Disconnect the meter and reconnect power. 9. Move the actuator’s output shaft in the desired direction to verify that the cam lobe moves away from the switch lever. If not correct, return to step 2 and reset the cam to the proper orientation. 10. Replace covers and tighten cover bolts to 10 Ib-ft (14 N•m) torque.

33 CALIBRATION Direction Change DIRECTION OF OUTPUT SHAFT ROTATION The direction of output shaft rotation is determined by observing the end of the actuator output shaft. The rotation direction desired from an increasing signal—clockwise or counterclockwise— should be specified at the time of order. If not specified, the output shaft is factory-set to rotate clockwise in response to an increasing signal. NOTE: Changing direction of rotation does not change the setting of the auxiliary switches. CHANGING DIRECTION OF OUTPUT SHAFT ROTATION Procedures vary depending upon the actuator model number. The number is listed on the actuator nameplate. Determine the model number and refer to one of the following procedures. CAUTION Be sure the actuator is disconnected from the line voltage and that all auxiliary switches are disconnected from the external power sources before beginning the direction change procedure. Models 11- __3 and 11- __4 No changes are necessary for these models other than resetting the travel index. Model 11- __5 1. Remove the control end cover and extensions, if applicable (5/16” bolt heads). 2. Interchange the wires connected to terminals 1 and 5 of the potentiometer (i.e., the wire to terminal 1 should be moved to terminal 5 and vice versa). The wire to terminal 3 should not be moved (wiper connection). See table on page 34. 3. Reset the travel index. 4. Reset the potentiometer wiper according to the film potentiometer calibration instructions on page 35. Model 11-__7 NOTE: On Model 11-__7 units equipped with an auxiliary film potentiometer, the auxiliary potentiometer is the one mounted closest to the actuator body. 1. Remove the terminal cover, control end cover and extensions, if applicable (5/16” bolt heads). 2. Interchange the wire jumpers connected to terminals M and N. 3. Change the wires connected to the ends of the potentiometer for the ESR—this is the potentiometer farthest from the actuator body—using the table on page 34 as a guide (i.e., the wire to terminal 1 should be moved to 5 (or vice versa) and the wire to terminal 2 should be moved to 4 (or vice versa)). The wire to terminal 3 should not be moved (wiper connection). 4. If your actuator is not equipped with an auxiliary potentiometer, skip to step 6. 5. Interchange the wires connected to terminals 1 and 5 of the auxiliary potentiometer—this is the potentiometer closest to the actuator body (i.e., the wire to terminal 1 should be moved to terminal 5 and vice versa). The wire to terminal 3 should not be moved. 6. Replace the terminal cover. Torque the cover bolts to 10 Ib-ft (14 N•m). Reset travel index. 7. Reset the potentiometer wiper according to the film potentiometer calibration instructions on page 35. Models 11-__6 and 11- __8 1. Remove the terminal compartment cover, control end cover and extensions, if applicable (5/16” bolt heads). 2. For model 11-__8, interchange the wire jumpers connected to terminals M and N. 3. For both models, determine the correct feedback signals from the wiring diagram supplied with your actuator (CC, DD, EE). 4. FOR CURRENT FEEDBACK APPLICATIONS: Record the color and location of the feedback signal wires (for reconnection later). Remove the two feedback wires. Connect a mA meter in series with a 200 ohm load resistor. FOR VOLTAGE FEEDBACK APPLICATIONS: Connect a voltmeter across the feedback terminals, DO NOT remove the feedback signal wires. See the table on page 61 for feedback terminals. 5. Reconnect actuator power. 6. Drive the output shaft until the CPS-5 output is 50% of the range (e.g., for 4–20 mA signal range, set output to 12 mA). 7. Ensure Handswitch is in “STOP” position. 8. Using a 7/64" hex wrench, loosen the CPS-5 rotor clamp. Continued

34 Models 11-__6 and 11- __8 (Continued) 9. Rotate the CPS-5 rotor 180° and set the output back to the mid-range (e.g., 12 mA). 10. Tighten the rotor clamp. 11. Run the actuator to the 0% and 100% positions. Record the CPS-5 output at these positions. 12. Subtract the outputs recorded at the two positions and compare with the desired output signal span (e.g., 16 mA for a 4–20 mA signal range). The difference between the measured span and the desired span is the span error. 13. With the actuator at the 100% position, turn the span potentiometer to adjust the CPS-5 output signal by 1/2 of the span error calculated in step 12. Turning the span potentiometer CW increases the span equally at both ends. Turning the span potentiometer CCW decreases the span equally at both ends. See the figure on page 37 for the location of the span potentiometer. 14. Loosen the CPS-5 rotor clamp and rotate to achieve the desired value of maximum output signal (e.g., 20 mA for a 4–20 mA signal range). Rotation of the CPS-5 rotor moves the entire signal range up or down. 15. Tighten the CPS-5 rotor clamp to 5 Ib-in (.56 N•m) torque. Maintain a 0.031" (.8 mm) clearance between the rotor clamp and stator. 16. Run the actuator to the 0% and 100% positions and check the output signal for desired span. If incorrect, repeat the procedure from step 2. 17. Remove the meter and resistor and reconnect the feedback wiring. 18. Replace covers and tighten cover bolts to 10 Ib-ft torque. Reset travel index. 19. Model 11-__8: Check ESR-5 board calibration by following the “Checking Calibration Procedure” on page 39.

35 CALIBRATION Feedback Signal Feedback signal calibration is necessary to ensure that the signal correctly corresponds to the actuator’s output shaft position. All actuators are shipped with the feedback calibrated for full 100° travel (90° for 11-16_/-26_/-36_/-46_) of the output shaft unless otherwise specified at the time of order. Minimum shaft travel available on Group 11 actuators is 60°. The procedure to check and set feedback calibration varies by model number. The model number is listed on the actuator nameplate. Determine the model number and refer to the proper procedure below. NOTE: The travel limit switches must be properly adjusted before the feedback signal is calibrated. The feedback signal must be calibrated before the demand Demand signal can be calibrated. Film Potentiometer Calibration Models 11-__5 and 11-__7 NOTE: The auxiliary film potentiometer is mounted closest to the actuator body on such optionally equipped model 11-__7 units. When properly adjusted, the auxiliary potentiometer feedback signal should be maximum with the actuator output shaft at the 100% (maximum Demand signal) position. At 50% of travel the signal should be mid-span. At the 0% position, the signal should be minimum. If either the auxiliary or main potentiometer on option 7 units is out of calibration, or if the feedback potentiometer on option 5 units is out of calibration: 1. Remove the ESR cover and the control end cover (5/16” bolt heads). 2. Loosen the clamping screw (use 9/64" hex wrench) on the potentiometer wiper so that it is just snug on the shaft. 3. Move the actuator to the 0% position. 4. On Model 11-__7, connect a voltmeter between the terminal with the green lead (either terminal 2 or 4) and the adjacent terminal (either terminal 1 or 5). Measure and record the voltage. Now connect the voltmeter between the terminal with the yellow lead (+) and the terminal with the green lead (–) and set the wiper on the potentiometer until the meter reads 30 mV greater than the voltage recorded in the first part of this step. On models 11-__5, set the wiper about 5 degrees above the position where the minimum output is reached, or as required by the control system. NOTE: Be sure that the wiper spans the resistive and collector elements equally, and does not touch the areas of low resistance at either end of the film element. 5. Tighten the clamping screw to 5 Ib-in (.56 N•m) torque. 6. Operate the actuator between the 0% and 100% positions. Verify that the feedback signal is properly adjusted. 7. Use the manual Handwheel to move the actuator to the mechanical limit; do not over-torque, as damage may result. 8. Check that the wiper does not come off the resistive element. This may be verified by monitoring the output voltage and ensuring it does not fall from maximum value. If not correct, return to step 2. 9. Replace the control end cover and the ESR cover. Torque the cover bolts to 10 Ib-ft (14 N•m). CPS-5 Calibration Model 11-__6 and 11-__8 These models are equipped with a Contactless Position Sensor (CPS-5) for position sensing and feedback. On model 11-__8, the CPS-5 also delivers a position signal to the Electronic Signal Receiver (ESR-5). Adjusting the remote feedback signal will automatically adjust the position signal to the ESR-5 on these models. CPS-5 units are designed to provide position feedback without contacting or wiping surfaces. On option 8 units, the CPS-5 includes a Monitor/ Isolator board which detects high and low out-of- limit conditions. This board monitors the CPS-5 position signal and compares it to established limits. If the output exceeds normal signal conditions, the board relay contact opens. This relay may be used for remote signal indication or activation of Loss-of-Signal operation of the actuator. The CPS-5 provides infinite resolution by incorporating a ferrite rotor on the control shaft and a ferrite stator mounted on the position sensing circuit board. To adjust the feedback signal, first adjust the span, then change the position of the rotor on the control shaft to adjust the zero.

36 Checking Feedback Signal Calibration The following procedure should be followed to check CPS-5 calibration: Tools required: mA / V dc Multimeter 1/2" Combination Wrench 200 ohm Resistor 1. Put electric Handswitch in “STOP” position. 2. Remove the terminal cover and the control end cover (5/16” bolt heads). 3. Determine the correct feedback terminals from the wiring diagram supplied with your actuator (CC, DD, EE). 4. FOR CURRENT FEEDBACK APPLICATIONS: Record the color and location of the feedback signal wires (for reconnection later). Remove the two feedback wires. Connect a mA meter in series with a 200 ohm load resistor. FOR VOLTAGE FEEDBACK APPLICATIONS: Connect a voltmeter across the feedback terminals. DO NOT remove the feedback signal wires. See table on page 61 for feedback terminals. 5. Drive the output shaft through its full range and check the feedback signal. When properly adjusted, the feedback signal should be maximum with the actuator’s output shaft at the 100% (maximum Demand signal) position. At 50% travel the signal should be mid-span. At 0%, the signal should be minimum. If not correct, proceed with the calibration procedure. NOTE: Tolerance on factory calibration is ±0.5% of span. Calibration Procedure Adjustment of the CPS-5 is necessary if the signal range requires an increase or decrease in value relative to the actuator’s output shaft rotation. Calibrate by turning the span potentiometer CW to increase the gain of the CPS-5. This has the effect of increasing the output at the high end and lowering the output at the low end equally. Signal span is determined by the CPS-5 model and ranging resistor selected. CAUTION Do not adjust the zero potentiometer to shift the span. To adjust the span, turn the span potentiometer on the CPS-5 position sensor board (see figure on page 37). The span potentiometer adjusts the CPS-5 so that an actuator output shaft rotation from 80° to 100° produces the specified output signal range. For output shaft rotation of between 60° and 79°, it may be necessary to remove resistor R8 (100 K ohm) to change the range of the span adjustment. An R8 value of 100 K ohms produces shaft output range of 80° to 100°; R8 = 249 K ohms produces shaft output range of 70° to 79°; and removing R8 produces shaft output range of 60° to 69°. See the figure on page 37 for location of R8 (positioned on raised turrets).

Put electric Handswitch in “STOP” position. 2. Remove the terminal cover and the control end cover (5/16” bolt heads). 3. Determine the correct feedback terminals from the wiring diagram supplied with your actuator (CC, DD, EE). This wiring diagram is located under the terminal cover. 4. FOR CURRENT FEEDBACK APPLICATIONS: Record the color and location of the feedback signal wires (for reconnection later). Remove the two feedback wires. Connect a mA meter in series with a 200 ohm load resistor. FOR VOLTAGE FEEDBACK APPLICATIONS: Connect a voltmeter across the feedback terminals. DO NOT remove the feedback signal wires. See the table on page 61 for feedback terminals. 5. Move the actuator to the 0% and 100% positions and record the CPS-5 output at these positions. 6. Subtract the outputs recorded at the two positions and compare with the desired output signal span (e.g., 16 mA for a 4–20 mA signal range). The difference between the measured span and the desired span is the span error. CALIBRATION Feedback Signal

With the actuator at the 100% position, turn the span potentiometer to adjust the CPS-5 feedback signal by 1/2 of the span error calculated in step 6. Turning the span potentiometer CW increases the span equally at both ends. Turning the span potentiometer CCW decreases the span equally at both ends. See figure below for the location of the span potentiometer. 8. Loosen the CPS-5 rotor clamp (see figure below) and rotate to achieve the desired value of maximum output signal (e.g., 20 mA for a 4–20 mA signal range). Rotation of the CPS-5 rotor moves the entire signal range up or down. 9. Tighten the CPS-5 rotor clamp to 5 Ib-in torque. Maintain a 0.031" (.8 mm) clearance between the rotor clamp and stator. 10. Run the actuator to the 0% and 100% positions and check the feedback signal for desired span. If not correct, repeat the procedure from step 5. 11. Remove the meter and resistor, then reconnect the feedback wiring. 12. Replace covers and tighten the cover bolts to 10 Ib-ft (14 N•m) torque. 13. Model 11-__8: Check ESR-5 board calibration by following the “Checking Calibration Procedure” on page 39.

38 CALIBRATION Feedback Signal / Demand Signal Adjusting the Zero Potentiometer The zero potentiometer is provided on CPS-5 models 20-4400-03 and -13 to change from a suppressed zero to a zero-based range (e.g., from 1–5 V dc to 0–16 V dc). The zero is adjustable from -5% to +30% of span. CAUTION The zero is factory sealed on all CPS-5 units except 20-4400-03 and -13. Do not attempt to adjust the zero on other mod els as misadjustment of feedback signal and monitor/ isolator functions will result. NOTE: Do not adjust the zero potentiometer to shift calibration. Adjust the rotor position only to shift calibration. The following example is given to illustrate how the zero is adjusted to effect a range change from 1–5 V dc to 0–16 V dc. 1. Install the 1–5 V dc unit as a 1–5 V dc range. Do not make any adjustments other than setting the rotor position. 2. Remove the jumper from terminals CC to DD and replace with a 3.01 K ohm resistor (see table on page 61). This shifts the range to 4–20 V dc. 3. Using a voltmeter at the appropriate output terminals, adjust the zero potentiometer with the actuator at minimum demand signal position so that output reads 0 V dc. This changes the range to 0–16 V dc. FEEDBACK SIGNAL MONITOR / ISOLATOR CPS-5 models 20-4400-12, -13, -14, and -15 are provided with a Monitor / lsolator board that delivers an isolated position signal to the Electronic Signal Receiver (ESR-5). The board monitors the CPS-5 position signal and compares it to established limits. If the output exceeds normal signal conditions, the monitor relay contact opens. This relay may be used for either a remote signal indication or activation of Loss-of-Signal (L.O.S.) operation of the actuator. No adjustments should be made on the Monitor / Isolator board. Signal Monitor Sensing Operation A red LED indicator and an SPST relay are mounted on the Monitor / lsolator board to indicate that power is on and that the CPS-5 position signal is within normal range. The contacts open at -4% and +104%, and close at -1% and +101%. The SPST relay is rated for 0.1 A resistive at 100 V dc. Loss of Signal Operation (L.O.S.) Actuators equipped with Electronic Signal Receivers (ESR-5) are configured so that the demand signal is connected through the position signal monitoring relay on the Monitor / Isolator board of the CPS-5. The Loss-of-Signal (L.O.S.) function of the ESR-5 may therefore be activated when the CPS-5 signals are outside the normal range —contact the factory for details and instructions. For more information on the L.O.S. function, review the following section on Demand Signal Calibration. DEMAND SIGNAL CALIBRATION All actuators equipped for milliamp or DC analog modulating applications include an Electronic Signal Receiver (ESR-5). The ESR-5 board consists of a voltage regulator, a signal amplifier, an error amplifier, and three solid-state output switches. The ESR-5 board controls the position of the Beck actuator according to the demand signal it receives. A position signal is delivered to the board from either a potentiometer or the CPS-5, which is compared with the demand signal. The error signal is then amplified and used to actuate either of two switches to drive the output shaft clockwise or counterclockwise until the signals are balanced. The third output switch is energized when the demand signal falls below a given setting (Loss Of Signal). The L.O.S. feature can be used to drive the output shaft to a predetermined position. Also, the L.O.S. LED will light on the ESR-5 board. See section on L.O.S., page 30, for further details. NOTE: The Demand signal is calibrated relative to the Feedback signal. Therefore, the over-travel limit switches must be properly adjusted and the Feed back signal calibrated before the Demand signal can be calibrated.

39 CALIBRATION Demand Signal Checking Calibration Using the demand signal, drive the output shaft through its complete range. Check the position feedback signal to confirm that a 10% Demand signal delivers a 10% position, a 50% signal delivers a 50% position, and a 90% signal delivers a 90% position. If the feedback signals do not correspond to the appropriate demand signals, then the ESR-5 must be calibrated. The tolerance on factory calibration is ±0.5% of span. CAUTION The signal circuit on ESR-5 units is not grounded. If grounding is required, connect terminal BB in the terminal compartment to ground, either on the actuator body or externally. Calibration Tips The demand signal can be varied by the automatic controller, but if that is impractical, a test box may be used. Connect the test box to positive terminal AA and negative terminal BB of the terminal block in place of the controller input. Span and zero adjustments are located near the edge of the ESR-5 board (see figure, page 41). Monitor the “FWD” and “REV” LEDs to make adjustments. When the actuator is balanced (with Handswitch in “AUTO” and not at an over-travel limit) both direction LEDs are off; when in L.O.S. mode, direction LEDs are off, but the L.O.S. LED is lit. When the output shaft is moving, the LED designating its direction of travel is lit and the other LED is off. When the actuator reaches its end of travel before balance is achieved, the LED will stay lit. Trim the adjustment so that the actuator just reaches the limit and the motor does not run. Clockwise rotation of either span or zero adjustment causes the output shaft to drive toward the zero (minimum demand signal) position. Calibration Procedures NOTE: Two calibration procedures are described below. The first procedure is to be followed if the span is in error by less than 15%. If the span is in error by more than 15% follow the second procedure. CAUTION Actuator will run during the following procedures. Tools required: 3/32" Screwdriver 1/2" Combination Wrench 1/4" Screwdriver mA / V dc Multimeter 200 Ohm Resistor If the span is in error by less than 15%: 1. Turn the Handswitch to the "STOP" position. 2. Remove the ESR cover and the terminal block cover (5/16” bolt heads). 3. Determine the correct external feedback signal terminals from the wiring diagram supplied with the actuator (located on the inside of the terminal block cover). Connect a meter (if applicable) to monitor the feedback signal. Refer to the "Feedback Signal Calibration" section beginning on page 35 for instructions on how to connect the meter. Note: For actuators equipped with control option 7 without an auxiliary potentiometer, it is not possible to use terminals CC, DD and EE for signal measurements during calibration; instead, an external reference must be used to determine the actuator output shaft position. 4. Connect a signal source to the demand signal terminals, AA (+) and BB (–). 5. Turn the Handswitch to the "AUTO" position. 6. Apply the desired 0% demand signal to the actuator (e.g., 4 mA for a 4–20 mA input). 7. Using a 3/32" screwdriver, adjust the zero potentiometer CCW until the motor runs and the output shaft position is at least 2° from the desired 0% position. Both the “REV” & “FWD” LED will be off. 8. Adjust the zero potentiometer CW in small increments until the output shaft is at the 0% position. For actuators equipped with external feedback, the feedback signal reads 0% (e.g., 4 mA for a 4–20 mA signal). Once at the 0% position, both LEDs should be off. 9. Apply the desired 100% demand signal to the actuator (e.g., 20 mA for a 4–20 mA signal). 10. Using a 3/32" screwdriver, adjust the span potentiometer CW until the actuator motor runs and the output shaft position is at least 2° from the desired 100% position. The “FWD” LED will light and remain lit. 11. Adjust the span potentiometer CCW in small increments until the output shaft is at the 100% position. For actuators equipped with external feedback, the feedback signal reads 100% (e.g., 20 mA for a 4–20 mA signal). The “REV“ LED will light and the “FWD” LED deactivate. Once at the 100% position, both LEDs should be off. Continued

40 12. Apply the desired 0% demand signal and confirm that the output shaft is at the 0% position (the feedback signal reads 0%). If not, adjust the zero potentiometer. 13. Apply the desired 100% demand signal and confirm that the output shaft is at the 100% position (the feedback signal reads 100%). If not, adjust the span potentiometer. 14. Repeat steps 12 and 13 until the meter readings stay within an acceptable range. 15. Remove the meter and any local signal sources and reinstall the demand signal and feedback signal wiring. Replace the compartment covers and tighten the bolts to 10 lb-ft (14 N•m). For a span error greater than 15%: 1. Turn the Handswitch to the "STOP" position. 2. Remove the ESR cover and the terminal block cover (5/16” bolt heads). 3. Determine the correct external feedback signal terminals from the wiring diagram supplied with the actuator (located on the inside of the terminal block cover). Note: For actuators equipped with control option 7 without an auxiliary potentiometer, it is not possible to use terminals CC, DD and EE for signal measurements during calibration. Instead, an external reference must be used to determine the actuator output shaft position. 4. Connect a meter (if applicable) to monitor the feedback signal. 5. Turn the Handswitch to the "AUTO" position. 6. Short the demand signal terminals AA and BB. 7. Short resistor R35 temporarily with a clip lead. Note: The board has conformal coating; take extra care to ensure proper connection. 8. Using a 3/32" screwdriver, adjust the zero potentiometer CW in small increments until the output shaft is at the 0% position. For actuators equipped with external feedback, the feedback signal reads 0% (e.g., 4 mA for a 4–20 mA signal). 9. Remove the short on the demand signal terminals and apply a demand signal equal to the span (e.g., 16 mA for a 4–20 mA signal). If the actuator has not been wired, the demand signal is connected at terminals AA (+) and BB (–). 10. Using a 3/32" screwdriver, adjust the span potentiometer CCW in small increments until the output shaft is at the 100% position. For actuators equipped with external feedback, the feedback signal reads 100% (e.g., 20 mA for a 4–20 mA signal). 11. Remove the clip lead from R35. Apply the desired 100% demand signal (e.g., 20 mA for a 4–20 mA signal). 12. Adjust the zero potentiometer CCW (may require 10–15 turns) until the output shaft is at the 100% position (the feedback signal reads 100%). 13. Apply the desired 0% demand signal and confirm that the output shaft is at the 0% position (the feedback signal reads 0%). If not, adjust the zero potentiometer. 14. Apply the desired 100% demand signal and confirm that the output shaft is at the 100% position (the feedback signal reads 100%). If not, adjust the span potentiometer. 15. Repeat steps 13 and 14 until satisfied with the adjustment. 16. Remove the meter and any local signal sources and reinstall the demand signal and feedback signal wiring. Replace the compartment covers and tighten the bolts to 10 lb-ft (14 N•m). Span The basic span adjustment of the ESR-5 is 2–6 volts dc. This is adjustable with the 20-turn span potentiometer. To make the span adjustable from 2–9 volts dc, remove jumper J2. To make the span adjustable from 9–12 volts dc, remove jumper wire J1. To make the span adjustable from 12–16 V dc, remove J1 and J2. See figure on page 41 for location of jumpers on the ESR-5 board. Zero The basic zero adjustment is -20% to 100% of span. This is adjustable with the zero potentiometer. For split range applications, see page 26. Filter Adjustment The input filter is adjusted at the factory for maximum attenuation of disturbances on the demand signal (fully CW). This introduces a 1% drift (with 60 second timing) in response to a loss of Demand signal when “stay-in-place” is selected. If this is objectionable or if livelier response is desired, the filter action can be reduced by turning the filter adjustment potentiometer CCW a sufficient amount. Fully CCW takes the filtering out completely but in some cases may lead to undesirable cycling. If this happens, turn the adjustment CW until the cycling is damped out. See figure on page 41 for location. CALIBRATION Demand Signal Calibration Procedures (Continued)

41 Deadband Adjustment The deadband values of 0.6% for CPS-5 or film potentiometer operation are chosen to satisfy the requirements of most control systems. If excessive process and / or signal noise is present, the actuator may be subject to unnecessary cycling. It is recommended that excessive noise be reduced at the source in order to prevent unnecessary cycling. This will improve process control and prolong component life. If it is not possible to eliminate the excessive noise, the actuator’s deadband can be widened; however, this will reduce the resolution of the actuator. Widening the deadband to 1% can be accomplished by removing jumper J3 on the ESR-5 board. Further change of the deadband is possible by changing the value of R42, but only after J3 is removed. See table below. DEADBAND/RESISTOR VALUES J3 R42 Deadband Remove 4.99 MΩ 1.0% Remove 3.30 MΩ 1.6% Remove 2.20 MΩ 2.4% Remove 1.50 MΩ 3.5% L.O.S. Trip Point If the Demand signal drops below a predetermined value, the L.O.S. feature is activated. For example, if the Demand signal is 4–20 mA, the L.O.S. trip point would be approx. 1.92 mA, with normal operation resuming before the signal reaches 4.0 mA. If the Demand signal is 1–5 V, the L.O.S. trip point would be 0.48 V, with normal operation resuming before the signal reaches 1 V. If it is necessary to change the L.O.S. trip point, resistors R20 and R21 must be replaced. See the applicable table below. The L.O.S. function may be disabled by removing R19. L.O.S.

43 MAINTENANCE Routine LUBRICATION / GEARING Periodic lubrication is not required on Beck actuators. However, if your actuator has a linkage with rod ends supplied by Beck, the rod ends should be included in your scheduled lubrication program. During major maintenance outages, it is recommended that older actuators should be inspected to ensure that the gearing is not worn or damaged. CAUTION Before removing the gear module assembly from the actuator body, secure the output shaft to prevent movement. To inspect the gears, remove the gear module assembly on the 11-2__, -3__ and -4__. On Model 11-1__, the motor must be removed to access the gears. Clean the gears, removing as much old lubrication as possible. Examine the gear teeth, shaft bore, and gear shafts for signs of excessive wear, scoring, or other damage. If there is no evidence of damage to the gearing, recoat the teeth and shaft bores of all gears with a heavy layer of Fiske Lubriplate GR-132 or equivalent (GR-132 is an extreme pressure grease with polymer additives). The ball bearing on the output shaft and crown gear shaft have double grease seals and require no maintenance for the life of the bearings. Inspect all other grease seals and replace any that show wear. Reassemble the actuator, referencing the outline dimension drawings beginning on page 6 for appropriate bolt torques. If it should ever be necessary to replace the output shaft assembly, 3rd combination gear, or output shaft bearings, a major overhaul is required and the actuator must be returned to the factory for a repair evaluation. 11-4__ Gear Module

44 MAINTENANCE Component Replacement This section covers replacement of many components of the actuator. Note that some components are not field-repairable. Refer to the outline dimension drawings on pages 6–12 and to the cutaway drawings in the components appendix for location of components on the actuator. If it should ever be necessary to replace the output gear, shaft, or output shaft bearings, a major overhaul is required and the actuator should be returned to the factory. During a major overhaul, the factory repair department will update the actuator to include all possible engineering improvements. See "HOW TO OBTAIN SERVICE" at the end of this manual. Gaskets During routine service, inspect removed cover gaskets for wear or damage. In order to protect internal components, worn or damaged gaskets and O-rings should be replaced. To remove, scrape all of the old adhesive and gasket material from the body housing and cover, if necessary. Replacement gaskets are self-adhering, silicone rubber. Peel the backing off the replacement gasket and carefully apply to the actuator body. Seals Worn or damaged output shaft, control end shaft, and motor shaft seals should be replaced to prevent damage to internal bearings and drive train parts. To remove the shaft seal, push the blade of a small screwdriver along the shaft and under the seal lip. CAUTION: The seal is approximately 1/4" (6.35 mm) wide. Do not force the screwdriver blade beyond the width of the seal; damage to the shaft bearing could result. Pry up on the seal and force it out of the housing. Clean the shaft and housing then press in the replacement seal with the closed side facing outward. Bearings The Beck electric actuator contains ball bearings on the output shaft, control end shaft, and motor shaft. Bushings and thrust washers are used on combination gears. Field replacement of these components is not recommended. Motor shaft bushings in the body of the 11 -1__ and 11-4__ can be replaced. TIP: To remove, fill the bushing with a heavy grease. Select a drive pin that slip fits into the bushing. Insert the pin into the bushing and tap with a mallet. This will force the bushing out of the body casting. Motor The control motor is not field-repairable. Disassembly of the motor will result in a loss of torque that can only be restored by returning the motor to the factory for re-magnetizing. CAUTION Before removing the control motor, block the actuator crank arm to prevent the crank arm and the gear train from moving when the motor is removed. To remove the motor, first disconnect the motor wires in the terminal compartment of the actuator. In the 11-2__, -3__, and -4__ actuators, remove the terminal block and plate as an assembly. Remove the black wire from the terminal post, cut the red motor wire near the red-yellow-red butt joint and disconnect the green wire from the motor capacitor. Remove the mounting bolts and motor. Carefully slide the motor out of the actuator body. To install the motor, insert the three-wire sleeve through the wire hole in the motor mount and into the terminal compartment. Carefully slide the motor into the actuator body. Rotate the motor shaft, if necessary, to engage the pinion with the first combination gear. Install motor mounting bolts and torque to recommended values. Reconnect the motor wires. See the following section for reinstalling the terminal plate. Motor Resistor and Capacitor The motor resistor and capacitor are located under the terminals in the terminal compartment. To replace a resistor or capacitor, remove the terminal cover. In the 11-2__, -3__, and -4__, remove the terminal plate. Remove the existing part and transfer the wires one at a time to the replacement part. Inspect the terminal plate gasket and replace if necessary. To ensure a watertight seal between the plate and gasket, coat the gasket with a thin film of grease before replacing the terminal plate. Torque the screws to 3 Ib-ft (4 N•m).

45 SELF LOCKING MECHANISM (SLM) The Self Locking Mechanism (SLM) is assembled to the front of the motor and couples the motor to the gear train. The primary function of the SLM is to lock the gear train in place when the motor is de-energized. When the motor is energized, the SLM releases and allows the motor to drive the gearing. There is no recommended maintenance interval for the SLM. The SLM can last for many years in normal service. SLM wear is a function of loading and the number of starts/stops the motor experiences over time. Overloading or stalling the actuator will accelerate SLM wear. Signs of wear include the inability of the actuator to hold position when the motor is de- energized. This could result in persistent on-off oscillation. Severe SLM wear or damage may result in a loss of torque at the output shaft. It is often possible to confirm SLM wear or damage by checking motor operation with the Handwheel. Place the Handswitch in the STOP position, and rotate the motor Handwheel back and forth. There should be free play before the motor pinion/gearing turns (up to one tenth of a full Handwheel rotation). Lack of free play or rough motor movement may indicate the need for SLM reconditioning. Disassembly and close inspection of the SLM components is required to fully evaluate its condition. WARNING Electrical shock hazard. Disconnect power before proceeding. Support the load before removing the motor/SLM from the actuator. DISASSEMBLY AND CLEANING When wear or damage is suspected, disassembly and cleaning may be required to determine the extent of needed repairs. Individual parts may be replaced, with the exception of the actuator collar, which is not field replaceable. Refer to the illustration on page 46. For SLM disassembly and inspection: 1. Disconnect power from the actuator. 2. Secure the actuator load, and remove the motor assembly (see page 44). Handle the motor with care so as not to damage the rotor shaft. 3. Pushing down firmly on the pinion, measure the gap between the stop collar and the thrust washer. This distance should measure 0.015 ± 0.005” for motors on models 11-1__, 11-2__, and 11-3__. This distance should measure 0.025 ± .005” for motors on models 11-4__. An excessive gap indicates worn SLM components. 4. Use a felt tip pen to mark the location of the stop collar (or shaft clamp collar) on the shaft. Support the end of the rotor shaft to prevent it from bending, and drive the 1/8” spring pin out (or loosen the shaft clamp collar). Carefully (the spring assembly is spring-loaded), remove SLM PART NUMBERS Actuator Model No. 11-1__ 11-2__ / 11-3__ 11-4__ Motor Assembly Part No. 20-2204-01 20-2700-20 20-2701-20, -51 20-2704-21 20-2705-21, -51 20-2201-31, -32, -33 SLM Rebuild Kit Part No. 12-8060-00 12-8060-15 12-8060-16 12-8060-17 12-8060-18 12-8060-13 Kit Includes Parts: Part No. Spring 14-9980-01 14-9980-10 14-9980-12 14-9980-01 14-9980-06 14-9980-26 Friction Material 14-9410-04 13-0080-04 14-9410-04 14-9409-22 Spring Pin N/A 10-7111-06 10-7111-03 10-7111-05 Shaft Clamp Collar 20-2100-05 N/A N/A N/A Thrust Washer / Bearing 14-9400-21 14-9400-16 13-0350-01 14-9400-02 Pinion 14-9940-44 14-9940-10 14-9940-06 14-9940-17 Steel Ball 14-9420-01 (8) 14-9420-02 (6) 14-9420-01 (8) 14-9420-03 (8) Locking Disc 14-9330-05 14-9330-15 14-9330-05 14-9330-19 Steel Shim N/A 30-0315-23 30-0315-45 (2) - Steel Shim N/A 30-0315-24 30-0315-46 (2) - Motor Gasket 20-0660-15 20-0660-27 20-0660-08 Instruction Sheet 80-0016-16 80-0016-05 80-0016-07 80-0016-02 Terminal Joint 20-0032-01 (3) Slip-on Terminal 20-0030-01 Spacer N/A 20-2090-03 O-ring N/A 14-9840-16 Continued

Further d i s a s s e m b l y w i l l r e s u l t i n demagnetization of the motor and loss of the required torque. 5. Clean grease from the pinion and locking disc for inspection. A small amount of dust residue from the friction material is normal. Clean the actuator collar detents with a rag and inspect for wear. Inspect the friction material for excessive wear or damage. If the friction material does not appear to be damaged, clean with alcohol to remove any contaminants. 6. Identify worn parts and replace as needed. Note, wear on the pinion teeth may indicate wear on the meshing gear. Further inspection of the gear module assembly is recommended. Drive collar detent wear will require factory repair of the motor. REPLACEMENT AND REBUILD INSTRUCTIONS 1. If the friction material requires replacement, scrape off the old friction material and thoroughly clean the bonding surface to ensure flatness for the new friction material. Glue the new friction material in place with Loctite 454 Instant Adhesive or equivalent, taking care to keep the material flat and clean. 2. Apply a film of grease (Fiske Lubriplate GR-132 or equivalent) to the surface of the ball detents (12 or 16 places depending on the model). Apply a thin film of grease to the inner diameter of the locking disc bore. Do not let the grease contact any friction surfaces. Excess grease can contaminate the friction surface and reduce SLM effectiveness. 3. With the motor shaft pointed up, place a steel ball into each of the actuator collar detents. Install the locking disc and place a steel ball into each of the detents on the top of the locking disc.

47 for your model number on the next page. Models 11-1__, 11-2__ & 11-3__ 4. Install the pinion, thrust bearing/washer, and stop collar (or shaft clamp collar). On model 11-1__ actuators, the white side of the thrust washer should face the pinion. Make sure all steel balls are properly seated in the detents of the actuator collar, locking disc, and pinion. Align the stop collar (or shaft clamp collar) and shaft marks made during disassembly and insert a 1/8” pilot punch through the stop collar hole and into the motor shaft (or tighten the button head cap screw in the shaft clamp collar to 15 lb-in. (1.7 N•m)) to hold it in place. 5. Pushing down firmly on the pinion, measure the gap between the stop collar (or shaft clamp collar) and the thrust bearing/washer. This distance should measure 0.015 ± .005”. This space is necessary to ensure proper operation. Add shims as necessary. Install the new 1/8” spring pin while supporting the shaft (if not equipped with the shaft clamp collar). 6. Install the spring by slipping it over the pinion flange and twisting it into place. 7. On model 11-1__ actuators, reassemble combination gears onto the motor end. On all models, recoat the gear teeth and components above the pinion liberally with a layer of Fiske Lubriplate GR-132 or equivalent. Models 11-4__ 4. Install the spring on top of the locking disc. Compress the spring by pushing down with the pinion. While holding the pinion in place, install the spacer, thrust bearing, and castle nut (stop collar). Note: The grooved washers on each end of the thrust bearing have differently sized holes; the end with the washer having the smallest hole should be installed next to the castle nut. Thread the castle nut on to the shaft to hold the spring in compression. 5. Replace the front motor end (See figure below) O-ring and install the front motor end with the (4) 1/4-20 screws in a crisscross pattern, torquing to 6 lb-ft (8 N•m). Place RTV around the wire entry into the motor. 6. Pushing down firmly on the pinion, measure the gap between the castle nut and the thrust bearing. This distance should measure 0.025 ± .005”. This space is necessary to ensure proper operation. Tighten or loosen the castle nut as necessary to achieve the proper gap and simultaneously align one of the slots with the hole in the motor shaft. One complete slot rotation will change the gap by 0.009”. Install the new 1/8” spring pin while supporting the shaft. 7. Recoat the gear teeth and components above the pinion liberally with a layer of Fiske Lubriplate GR-132 or equivalent.

50 CPS-5 Field repair of the CPS-5 is not recom mended. WARNING Electrical shock hazard. Disconnect power before replacing the CPS-5. When replacing the CPS-5, this includes the rotor and stator/circuit board assembly. When returning the CPS-5 to the factory for service, do not separate the rotor and stator/circuit board assemblies from their mounting plates. The rotor should be held inside the stator with rubber bands when shipping. The CPS-5 is configured to produce a position signal voltage between 1 and 5 volts over 100 degrees of travel; units configured for 90 degrees of travel will produce a position voltage between 1.2 and 4.8 volts. Configured properly, the CPS-5 raw position signal (measured at TP1 & TP4) increases as the output shaft rotates clockwise. REMOVE THE EXISTING CPS-5 ASSEMBLY: 1. Run the actuator to its midpoint of travel with the local Handswitch. 2. Disconnect 120 V ac power to the actuator. Remove the terminal and control end compartment covers (1/2” wrench). 3. Record the wire colors on the terminal block of the CPS-5 (see illustration at left), then disconnect the wires. The terminals are spring-loaded. To remove a wire, press the tip of a small screwdriver into the slot at the top of the small lever. Push down to open the spring-loaded contact and release the wire. 4. Pull the wires from the transformer (see illustration) back through the wire hole in the CPS-5. 5. Loosen and remove the 3 hex studs that clamp the CPS-5 in place. Ensure that the inboard hex stud is not loosened as the outboard stud is loosened. 6. Slide the CPS-5 stator assembly off the three mounting bolts. 7. Note the position of the rotor clamp, then loosen the rotor clamp screw and remove the rotor from the shaft. INSTALL THE NEW CPS-5 ASSEMBLY: 8. Remove the rotor from the replacement CPS-5 assembly. Slide the rotor, clamp end first, onto the control shaft as close to the mounting plate as possible. Leave the clamp loose. Position the clamp similarly to the one removed previously. 9. Slide the new CPS-5 assembly over the studs and rotor. Replace the hex nuts but do not tighten. Carefully slide the rotor back into the CPS-5 assembly. Twist the rotor while sliding to prevent damage to the assembly. Tighten hex nuts to 5 Ib-ft (7 N•m). 10. Thread the wires through the wire holes in the CPS-5 and reconnect them to the transformer and terminal block. 11. Restore 120 V ac power to the actuator and connect a meter to the output. CURRENT FEEDBACK APPLICA TIONS: Record the color and location of the feedback signal wires for re-connection later. Remove the two feedback wires. Connect a mA meter in series with a 200 ohm load resistor. VOLTAGE FEEDBACK APPLICA TIONS: Connect a voltmeter across the feedback terminals. DO NOT remove the signal feedback wires. 12. Insert a 0.031” (.80 mm) feeler gauge between the rotor clamp and stator. Position the clamp 0.031” (.80 mm) from the stator. 13. Rotate the rotor on the control shaft until the output on the mA or voltmeter reads 50% of signal span, then tighten the clamp to 5 Ib-in (.56 N•m) torque. 14. Check the feedback signal calibration as described on page 36.
