operation The electropneumatic positioner is mounted on pneumatic control valves. It is used to as- sign the valve stem position (controlled vari- able x) to the control signal (reference vari- able w). The electric control signal received from a control system is compared to the travel or rotational angle of the control valve and a signal pressure (output variable y) is produced for the pneumatic actuator. The positioner consists of an anisotropic magnetoresistive (AMR) sensor (2), an ana- log i/p converter (7) with a downstream booster and the electronics unit with microcontroller (4). The travel or opening angle is measured by the pick-up lever connected to a magnet and a non-contact AMR sensor (2) installed in the housing and the electronics. The motion of the pick-up lever causes the direction of the magnetic field to change. This change is sensed by the AMR sensor. The microprocessor determine the momen- tary valve position from this information. The position of the valve is transmitted to the microcontroller (4) over the A/D converter (3). The PD control algorithm in the micro- processor (4) compares this actual position to the 4 to 20 mA control signal (reference variable) after it has been converted by the A/D converter (3). In case of a system deviation, the operation of the i/p converter (6) is changed so that the actuator (1) is filled or vented by the downstream air capacity booster (7). The pneumatic air capacity booster (7) and the pressure regulator (8) are supplied with supply air. The output signal pressure supplied by the booster can be limited to 2.4 bar by soft- ware. The volume restriction Q (10) is used to opti- mize the positioner by adapting it to the ac- tuator size. Tight-closing function The pneumatic actuator is completely filled with air or vented as soon as the reference variable falls below 1 % or exceeds 99 % (see end positions set over parameter codes P10 and P11).

actuators The positioner is mounted to the rotary actu- ator using a mounting bracket. Refer to Table 4 on page 27 for the re- quired mounting parts as well as the acces- sories. Before attaching the positioner onto the SAMSON Type 3278 Rotary Actuator (160 cm²) or VETEC Type S160 Actuator, first mount the adapter (13) to the free end of the shaft end using four screws (11, 12). NOTICE On attaching the positioner as described be- low, it is imperative that the actuator's direc- tion of rotation is observed. 1. Place follower clamp (3) on the slotted actuator shaft or adapter (13). 2. Place coupling wheel (4) with flat side facing the actuator on the follower clamp (3). Refer to Fig. 12 to align slot so that it matches the direction of rota- tion when the valve is in its closed posi- tion. 3. Fasten the coupling wheel (4) and fol- lower clamp (3) tightly onto the actuator shaft using screw (4.1) and disk spring (4.2). 4. Mount connecting plate (6) or pressure gauge bracket (7) with pressure gauges to the positioner, making sure both O-rings are seated properly. 5 Fasten the mounting bracket (10) to the actuator using four screws (10.1). 6. Unscrew the standard follower pin (2) from the positioner's lever M (1). Use the metal follower pin (Ø5) included in the mounting kit and screw tight into the bore for pin position 90°. 7. Place positioner on the mounting bracket (10) and screw tight. Considering the actuator's direction of rotation, adjust le- ver (1) so that it engages in the slot of the coupling wheel (4) with its follower pin (see Fig. 13). It must be guaranteed that the lever (1) is parallel to the long side of the positioner when the actuator is at half its angle of rotation. 8. Stick the scale label on the coupling wheel so that the arrow tip indicates the closed position and it can be easily read when the valve is installed. 24 EB 8394 EN Attachment to the control valve – Mounting parts and accessories Fig. 12 · Direction of rotation

The screw fittings must be screwed into the connecting plate, the pressure gauge mount- ing block or the connection block from the accessories. The pneumatic connections are optionally designed as a bore with ¼ NPT or G ¼ thread. The customary fittings for metal and copper pipes or plastic hoses can be used. Keep the length of the line as short as possi- ble to avoid delays in control signal trans- mission. Note: The supply air must be dry and free from oil and dust. The maintenance instructions for upstream pressure reducing stations must be ob- served. Blow through all air pipes and hoses thor- oughly prior to connecting them. If the positioner is attached directly to the Type 3277 Actuator, the connection of the positioner's output pressure to the actuator is fixed. For attachment according to IEC 60534-6 (NAMUR), the signal pressure can be routed to either the top or bottom diaphragm chamber of the actuator, depending on the actuator's fail-safe action "Actuator stem ex- tends" or "Actuator stem retracts". For rotary actuators, the manufacturer's specifications for connection apply. 5.1.1 Signal pressure gauges To monitor the supply air (Supply) and sig- nal pressure (Output), we recommend mounting pressure gauges (see accessories in section 4.5). 5.1.2 Supply pressure The required supply air pressure depends on the bench range and the actuator's operat- ing direction (fail-safe action). The bench range is registered on the name- plate either as spring range or signal pres- sure range depending on the actuator. The direction of action is marked FA or FE, or by a symbol. Actuator stem extends FA (Air to open) Fail-safe position "Valve Closed" (for globe and angle valves): Required supply pressure = Upper bench range value + 0.2 bar, minimum 1.4 bar. Actuator stem retracts FE (Air to close) Fail-safe position "Valve Open" (for globe and angle valves): For tight-closing valves, the maximum signal pressure pstmax is roughly estimated as fol- lows: pstmax = F + d p A 2 4 � � � � � [bar] 28 EB 8394 EN Connections

�p = Differential pressure across the valve [bar] A = Actuator diaphragm area [cm²] F = Upper bench range value [bar] If there are no specifications, calculate as follows: Required supply pressure = Upper bench range value + 1 bar. Note: The signal pressure at the output (38) of the positioner can be restricted to approx. 2.4 bar by setting parameter code P9 to ON. 5.2 Electrical connections DANGER! Risk of electric shock and/or the formation of an explosive atmosphere! – For electrical installation, observe the rel- evant electrotechnical regulations and the accident prevention regulations that apply in the country of use. – The following regulations apply to mounting and installation in hazardous areas: EN 60079-14: 2008 Explosive atmospheres – Part 14: Electrical instal- lations design, selection and erection. Risk of explosion due to electrostatic charging Avoid electrostatic charging of the plastic housing when mounting and servicing the positioner in hazardous areas. NOTICE – Adhere to the terminal assignment! Switching the assignment of the electrical terminals may cause the explosion pro- tection to become ineffective! – Do not loosen enameled screws in or on the housing. – The maximum permissible values speci- fied in the national EC type examination certificates apply when interconnecting intrinsically safe electrical equipment (Ui, Ii, Pi, Li and Ci). EB 8394 EN 29 Connections

Observe Clause 12 of EN 60079-14: 2008 when installing intrinsically safe circuits. The Subclause 12.2.2.7 applies when run- ning multi-core cables containing more than one intrinsically safe circuit. In particular, the radial thickness of the con- ductor insulation for common insulation ma- terials, such as polyethylene, must have a minimum radial thickness of 0.2 mm. The diameter of an individual wire in a fine-stranded conductor must not be smaller than 0.1 mm. Protect the conductor ends against splicing, e.g. by using wire-end fer- rules. Equipment for use in zone 2 In equipment operated with type of protec- tion Ex nA II (non-sparking equipment) ac- cording to EN 60097-15: 2003, circuits may be connected, interrupted or switched while energized only during installation, maintenance or repair. Cable entries The M20 x 1.5 cable gland is designed for a clamping range of 6 to 12 mm. The cage clamp terminals hold wire cross-sections of 0.2 to 1.5 mm² and addi- tionally have test connections for 1 mm probe tips. To remove the cable, press the tip of a screwdriver into the cage clamp terminal and pull out the wire at the same time. The wires for the reference variable must be connected to the terminals 11 and 12 lo- cated in the housing. Only use a current source!

Refer to section 7.11 for details and the code list in section 8). 7 Start-up – Settings WARNING! Do not perform a start-up while the process is running. On applying supply air and the electric con- trol signal, the control valve may move through its entire travel range/rotational an- gle range depending on the setting. � Connect the supply air (Supply 9). � Connect the 4 to 20 mA signal (terminals +11/–12). Do not touch the key panel! Note: After connecting the electrical signal (power supply), the positioner performs a calibration of the capacitive keys which takes approx. three seconds. During this time, do not touch the key panel. Otherwise, the keys will not work properly. Disconnect and reconnect the electrical sig- nal to restart the calibration of keys. LOW on the display indicates that the refer- ence variable is lower than 4 mA (0 %). The positioner is ready for operation with its default settings for most applications, pro- vided it has been mounted properly. Note: The positioner needs to be initialized again after the position of the volume re- striction has been changed. The positioner also needs to be initialized again after the setting for the fail-safe posi- tion has been changed. EB 8394 EN 33 Start-up – Settings

nal The fault indication icon and S (fail-safe position) appear on the display when the positioner has not yet been initialized. The reading indicates the lever positioner in de- grees relative to the longitudinal axis. � Code 0 appears on the display after con- necting the electrical signal to an initial- ized positioner. The positioner goes to the last active operating mode. 7.1 Enabling configuration Note: Before changing parameter settings, configuration must be enabled first by select- ing Code P19. If no settings are entered within three minutes, the enabled configuration function becomes invalid. Press or until Code P19 appears. Press to confirm selected code. P19 blinks. Press until OPEN appears on the display. Press to confirm unlocking. WARNING! During start-up the actuator stem moves. Do not touch the actuator stem or obstruct it to avoid risk of injury to hands or fingers. If the left or right outer bar element blinks (reading > 30°), the permissible angle of ro- tation has been exceeded. The positioner goes to the fail-safe position (SAFE). Make sure that the lever and pin position match the details as described in section 4. Note: The positioner has a function to moni- tor the working range. If the lever moves too close to the mechani- cal stops (risk of mechanical damage), the positioner vents the actuator and the valve moves to its fail-safe position (S displayed together with error code E8). In this case, check the positioner attachment. Reset the displayed error code by selecting RST (see section 7.12). 34 EB 8394 EN Start-up – Settings S Display when the positioner has not yet been initialized Enabling configuration over Code 19

Q The volume restriction Q is used to adapt the air delivery to the size of the actuator: � Actuators with a transit time < 1 s, e.g. linear actuators with an effective area smaller than 240 cm², require a re- stricted air flow rate (MIN setting). � Actuators with a transit time � 1 s do not require the air flow rate to be restricted (MAX setting). Intermediate settings are not permitted. Note: The positioner needs to be initialized again after the position of the restriction has been changed. 7.3 Adapting the display The data representation on the positioner display can be turned by 180°. If the displayed data appear upside down, proceed as follows: Press or until Code P1 appears. Press to confirm the selected code. P1 blinks.

Press to confirm setting. Note: The changed opening direction first becomes effective after the positioner has been re-initialized. 7.5 Defining the direction of action The direction of action is set to increas- ing/increasing by default. For checking purposes: After successfully completing initialization, the positioner display should read 0 % when the valve is closed and 100 % when the valve is open. If necessary, the direction of action can be changed either before or after initialization. The following correlation applies: Valve CLOSED OPEN Display 0 % 100 % ATO �� 4 mA 20 mA �� 20 mA 4 mA ATC �� 4 mA 20 mA �� 20 mA 4 mA � � Increasing/increasing � � Increasing/decreasing 7.6 Limiting the signal pressure If the maximum actuator force may cause damage to the valve, the signal pressure must be limited. Set Code P9 to ON. This limits the signal pressure to approx. 2.4 bar. Enable configuration at the positioner before activating the pressure limit function (refer to section 7.1) 36 EB 8394 EN Start-up – Settings

The following table lists all the parameter codes and their default settings. If you want to change the default setting of a parameter, proceed in the same manner as previously described.

self optimally to the friction conditions and the signal pressure required by the control valve. The type and extent of self-adaptation de- pends on the preset parameters. MAX is the default setting for the nominal range (Code P4). During the initialization process, the positioner determines the travel/rotational angle of the closing element from the CLOSED position as far as it will go in the other direction. Alternatively, a different travel can be se- lected in Code P4. Refer to section 8. WARNING! During the initialization, the control valve moves through its entire travel/angle of ro- tation range. Therefore, do not start initial- ization while a process is running, but only during start-up, when all shut-off valves are closed. Start initialization by activating Code P15 as follows: Press or to select Code P15.

indication icon appears at the bottom of the display. If the fault indication icon appears after a parameter code setting has been changed, this indicates that these settings do not match the values determined during initial- ization. See Code E1 (refer to section 8). Press or past Code P 0 or P 20, the respective error code E0 to E15 together with ERR appear on the display. Refer to the code list in section 8 for the cause of the errors and the recommended action. Example: If, for instance, a travel has been entered over Code P4 (nominal range) which is larger than the maximum valve travel possi- ble, the initialization process would be inter- rupted (error code E2) because the rated travel would not have been reached (error code E6). The valve moves to the fail-safe position (S indicated on the display). Display of the fault indication The nominal range (Code P4) must be changed and the positioner re-initialized to remedy this problem. Reset error codes The error codes E0 and E8 can be reset as follows: Press or until the error code appears. Press , ESC appears. Press or , RST appears. Press to reset error. The resetting procedure can be canceled by pressing when ESC appears. 42 EB 8394 EN Start-up – Settings S S S

nance. There are filters with a 100 m mesh size in the pneumatic connections for supply and output which can be removed and cleaned, if required. The maintenance instructions of any up- stream supply air pressure reducing stations must be observed. 10 Servicing explosion-protected devices If a part of the device on which the explo- sion protection is based needs to be ser- viced, the device must not be put back into operation until a qualified inspector has as- sessed it according to explosion protection requirements, has issued an inspection cer- tificate or given the device a mark of confor- mity. Inspection by a qualified inspector is not re- quired if the manufacturer performs a rou- tine test on the device prior to putting it back into operation. The passing of the routine test must be documented by attaching a mark of conformity to the device. Replace explosion-protected components only by original, routine-tested components from the manufacturer. Devices that have already been operated outside hazardous areas and are intended for future use inside hazardous areas must comply with the safety requirements placed on serviced devices. Before being used in- side hazardous areas, test the devices ac- cording to the specifications for servicing explosion-protected devices. EB 8394 EN 47 Maintenance
