Wiring Recommendations

Enhanced Electronic Governor EEG7000 with GAConfig Tool 8-2021-D6 PIB1009 EEG7000 Basic Wiring 6 Pin 3 - Magnetic Speed Pick-up A magnetic speed sensor detects when ring gear teeth pass the tip of the magnetic speed sensor. The output signal is an AC sine wave whose frequency is converted to crankshaft revolutions per minute (rpm). The following are required: • A magnetic pickup must be installed in the engine bell housing, ring gear case, or fabricated bracket. • All wires must be twisted and/or shielded for their entire length (14 turns per foot). • Ground shield to case. Do not tie case to ground. • The magnetic speed sensor voltage should be at least 1 V RMS while cranking. During operation, 5 to10 V RMS is recommended. • If the EEG7000 controller detects no input from the magnetic pickup, the controller sets the actuator to 0 V DC and the speed to 0 rpm. If the controller detects loss of magnetic pickup, LED 2 turns solid red and the system must be reset. • To reset the EEG7000, cycle DC power. • The magnetic speed sensor connections MUST BE TWISTED AND/OR SHIELDED for their entire length. • The speed sensor cable shield must only be connected to the case. The shield should be insulated to ensure that no other part of it comes into contact with engine ground, otherwise stray signals may be introduced into the speed switch. • Minimum gap between speed sensor and gear teeth is 0.02 in [0.5 mm]. When the engine is stopped, adjust the gap between the magnetic speed sensor and the ring gear teeth. Usually, backing out the speed sensor 3/4 turn after touching the ring gear tooth will result in a satisfactory gap. Aux accepts signals from: • GAC accessories • Auto synchronizers • Load sharing units • Other governing accessories The auxiliary (AUX) pin accepts input signals from load sharing units, auto synchronizers, and other governor system accessories. The AUX input from Pin 4 is activated by selecting Auxiliary Enable in the GAConfig Tool Advanced Configuration menu and selecting the desired Aux / Load Sharing pane. The AUX function decreases engine speed with increasing input voltage, the polarity shift function increases engine speed with in- creasing input voltage. AUX input is nominally 5.0 V +/- 5.0 V DC. The GAConfig Tool Aux/Load Sharing allows you to set polarity as decreasing or increasing speed. Pins 1 and 2 are dedicated to actuator usage. Polarity is not required. See your specific actuator manual for details. PINs 1 and 2 - Actuator Connection Pin 4 - Auxiliary Input

This is accomplished by tying inputs to ground or leaving them open. Fixed Speed 1 can be set to idle as required. Speed is set from the GAConfig Tool from the Engine Tuning menu in the Fixed Speed and Variable Speed panes. • To set variable speed, update to the desired rpm. See Section 10, Setting Variable Speed Parameters for more details. • Automatically calibrate Input Minimum and Input Maximum settings related to the variable speed potentiometer or other related control using Calibrate Minimum or Calibrate Maximum. • To calibrate the minimum percent set the potentiometer to the desired start value and click Calibrate Minimum button. • To calibrate the maximum percent set the potentiometer to the highest end value and click Calibrate Maximum button. • The difference between the analog minimum speed settings will be at least 25 % to prevent rough idle. EEG7000 Basic Wiring (CONTINUED) 6 Pin 7 provides analog input from external trim or variable speed potentiometers. Connect a 5 kΩ potentiometer between Pins 7, 9 and 12 as shown in Variable Speed. Pin 7 - ANALOG INPUT When the EEG7000 detects engine speed has reached the user defined Limit / Threshold value, the EEG7000 controller changes the state of Pin 8. Speed switch output (SSW) can provide overspeed protection, starter cutoff (crank termination), and other general aux- iliary functions. • The SSW adjustment range is 100 to 6000 rpm. The default value is 1800 rpm and the default state (Mode) is NORMALLY OPEN. • When NORMALLY OPEN is selected the SSW output on Pin 8 will energize at the set speed. When NORMALLY CLOSED is selected output from Pin 8 will de-energize at the speed setting. • When the LATCHING box is checked the SSW output state is fixed until power to the SSW is cycled. When the box is not checked the output state automatically resets at 0 rpm. The default is checked (ON). Pin 8 - Speed Switch Output (SSW)

Enhanced Electronic Governor EEG7000 with GAConfig Tool 8-2021-D6 PIB1009 Setting variable speed requires a potentiometer, available from GAC. A potentiometer calibration within the GAConfig Tool characterizes the selected potentiometer. Analog variable speed is enabled when Pins 5 and 6 are not grounded. To add a potentiometer: 1. Connect either a 5 kΩ potentiometer, 0 - 5 V DC or 4 - 20 mA speed input signal to Pin 9. 2. Set the Variable Speed Input Mode in the GAConfig Tool to 0 - 5 V DC or 4 - 20 mA. 3. To calibrate the potentiometer: a. Open Engine Tuning  Variable Speed. b. Set the potentiometer to the full CCW position and click Calibrate Minimum. c. Turn the potentiometer CW all the way and click Calibrate Maximum. d. Note the Input Actual result Variable Speed can be used as another fixed speed setting if both Speed Minimum and Speed Maximum parameters are set to the same rpm and no potentiometer is connected. For more details on setting variable speed or installing a potentiometer see Section 10, Setting Variable Speed Parameters. 0 - 5 V DC or 4 - 20 mA Signal 5 kΩ Potentiometer Pin 9 - ANALOG Variable Speed • The CAN bus must be terminated at both ends by a 120 k Ω resistor. • Use cable harness CH1520, 7 AWG, or EC1502 mating con- nector kit with twisted pair that meets SAE J1939 or SAE J1128 standards.

Enhanced Electronic Governor EEG7000 with GAConfig Tool 8-2021-D6 PIB1009 GETTING STARTED Wiring between the engine, the EEG7000 controller, and the actuator should be completed before starting the engine. See Sections 5 and 6 for more wiring details. The following are the minimum wiring requirements: • Connect Actuator to EEG7000 (Pins A and B) • Connect Actuator to magnetic pickups (Pins 1 and 2) • Connect EEG7000 to battery (Pins C and D) • Connect USB from EEG7000 to PC The EEG7000 can be set up and used straight out of the box, with an actuator attached, using default settings. This section details the initial installation and setup using the default settings. Wiring between the engine and the EEG7000 is required, and reviewing this document and default settings is advised. There are two sets of parameters to work with: basic engine performance and engine tuning. Getting Started gets your engine started. Engine Tuning improves performance. Before you start your engine: • Install the GAConfig Tool on a PC and connect the PC to the EEG7000 with the USB cable. • Provide power to the EEG7000 from the battery. • Install an actuator between EEG7000 and engine, following your actuators installation manual. • Set the following minimum settings in the GAConfig Tool on the Engine Tuning menu: • Overspeed for automatic actuator shutdown • Number of engine flywheel teeth • Fuel Limit • Acceleration and Deceleration • Actuator Ramp Rate • Starter Cutoff • Fixed Speed Settings FIXED SPEED SETTINGS Parameter Range Default Definition Speed 1 0 - 6000 1500 Selects one of three fixed speeds (rpm). Speed 2 and 3 150 - 6000 1500 Gain 1, 2, and 3 1 - 100 50 Set one Gain value for each fixed speed. At the GAConfig Tool: 1. At the Main menu select Engine Tuning. 2. Note if the Flywheel Teeth value is correct for you engine. If not, click the value to change it. 3. Enter values for all the all System Setup and Start-Up parameters. 4. Set the Fixed Speed values for Speed 1, Speed 2, and Speed 3. 9 INITIAL Wiring basic GAConfig Tool Settings Further descriptions on these and all parameters are in GAConfig Tool - Setting all Parameters

Enhanced Electronic Governor EEG7000 with GAConfig Tool 8-2021-D6 PIB1009 Once the parameter settings are reviewed and values updated as required, reconnect your fuel supply and start your engine. 1. Reconnect the fuel supply. 2. Crank the engine with DC power applied to the governor system. The engine should be at operating speed with no load. 3. The actuator/ fuel to the engine will be positioned to the level set by the Actuator Start Fuel (default is maximum fuel). Actuator Ramp Rate controls the rate at which fuel is increased to start the engine, 10 % by default. 4. If the engine is unstable after starting, open the GAConfig Tool and adjust the Gain, Stability, and Deadtime in the Engine Tuning  Tuning block, until the engine is relatively stable. 5. Once the engine is stable you can connect additional devices and further tune your engine. Do not rely exclusively on the governor system electronic actuator to prevent overspeed. A secondary shutoff device, such as a fuel solenoid must be used. The STOP - Engine Shutdown button shuts down the controller and actuator, not the engine. STOP shuts down the voltage to the controller; which disables the PWM output to the actuator; shutting down the engine. START YOUR ENGINE GETTING STARTED (CONTINUED) 9 To improve basic performance, with no load applied to the engine, complete the following: 1. At the GAConfig Tool open the Engine Tuning  Tuning and set the following: a. Increase the Gain by entering new value until instability develops. Gradually decrease the Gain until stability returns. Decrease the adjustment one count further to ensure stable performance. b. Increase Stability value until instability develops. Gradually decrease Stability value until stability returns. Decrease the value by one to ensure it is stable. If there is no instability leave set at 50. c. Set the DEADTIME to Low. If instability develops, change to High. Once the engine is running at operating speed, with no load, use the GAConfig Tool to adjust the parameter values to increase engine stability. Each speed parameter (Speed 1, 2, 3) has its own Gain parameter (Gain 1, 2, 3) setting. The speed selection number and active Gain are shown in Tuning. Stability is achieved by balancing PID: Gain, Stability, and Deadtime. • Gain (Proportional) changes the initial response of the speed controller. Increasing gain makes the engine more responsive to load changes while decreasing gain makes it less responsive to load changes. Avoid engine instability due to high gain when adjusting this parameter. Each fixed speed has a gain value associated with it. • Stability (Integral) changes the steady state response of the engine. Increasing stability allows the system to come to steady state speed faster, while decreasing the stability results in a more gradual transition to steady state speed. • Deadtime (Derivative) sets the transient response of the engine to high or low and affects stability during transient load changes. Increasing deadtime decreases the percent of overshoot and settling time during a transient load change while decreasing deadtime increases them. Setting Deadtime to High can cause random speed instability during steady state since small speed errors are amplified by this parameter. Additional adjustments may be required after engine load is applied. Normally, adjustments made at no load achieve satisfactory performance. Lead Circuit, Light Force Governing and Speed Anticipation are further described in Section 16, Additional EEG7000 Capabilities. NOTE Adjusting basic stability with fixed speed

Enhanced Electronic Governor EEG7000 with GAConfig Tool 8-2021-D6 PIB1009 10 Setting Variable Speed Variable speed parameters activate throttle or fuel control relative to the variable speed input signal. This requires a single remote speed adjustment potentiometer is installed to adjust the engine speed continuously over a specific speed range. At the Variable Speed  Voltage Speed Input Mode: • Voltage Input: (Select 0 - 5 V / Resistive) Voltage to 5.0 V, above 5.0 V the variable speed function is clamped at 100 %, rpm response to voltage is linear. • Current Input: (Select 4 - 20 mA) Speed Minimum sets the low speed at 4 mA. Speed Maximum sets the high speed at 20 mA. If the input current drops below 4 mA, variable speed is clamped at 0 %. If the input current level exceeds 20 mA, variable speed is clamped at 100 %. The rpm response to current is linear. VARIABLE SPEED Parameters Parameter Range Default Definition Variable Speed Input Mode 0 - 5 V DC or 4 - 20 mA 0 - 5 V DC Sets the variable speed input for the analog device. Speed Minimum 150 - 6000 rpm 1500 Minimum speed setting Variable Speed Start Gain 1 - 100 50 Gain to use when at the minimum speed while in variable speed. Speed Maximum 150 - 6000 rpm 1500 Maximum speed setting. Variable Speed End Gain 1 - 100 50 Gain to use when at the maximum speed while in variable speed. Input Minimum (Calibrate button) 0 - 75 % 0* Sets the range for the minimum variable speed. Range: 0 to 75 % and must be 25 % apart from end position. Calibrate automatically by clicking Calibrate Minimum. Input Maximum (Calibrate button) 25 - 100 % 100* Sets the range for the maximum variable speed. Range: 25 to 100 % and must be 25 % apart from start position. Calibrate automatically by clicking Calibrate Maximum. Input Actual 0 - 100 % 100 Status of the current variable speed input position. * % rpm Variable speed (rpm) based on current input or voltage expected results are shown here. Note the following: • If the Minimum Speed setting is higher than Maximum Speed, increasing the speed input signal / potentiometer position will de- crease rpm. • Minimum Speed and Maximum Speed setting ranges are 150 to 6000 rpm with default value of 1500 rpm. • Gain, Stability, and Deadtime values may need adjustment after engine load is applied. • Normally adjustments made at no load achieve satisfactory performance. • If further performance improvements are required, see Section 17, Troubleshooting, in this guide.

Set Variable Speed End Gain to optimize maximum gain. 6. To maintain engine stability at the minimum speed setting, add a small amount of droop using Droop in the GAConfig Tool Advanced Configuration menu. At the maximum speed setting performance will be near isochronous, regardless of the droop adjustment setting. 10 Setting Variable Speed (CONTINUED) SETTING VARIABLE SPEED If minimum speed is higher than maximum speed increasing the speed input signal position will decrease the rpm. NOTE

Enhanced Electronic Governor EEG7000 with GAConfig Tool 8-2021-D6 PIB1009 11 Adjusting for Droop Droop adjustments are made while the engine is running. Setting droop reduces the speed as fuel position (load) increases. To maintain engine stability, at the minimum speed setting, add a small amount of droop. At maximum speed performance will be near isochronous regardless of the droop adjustment setting. 1. Open the GAConfig Tool on your PC. From the Main menu, select Engine Tuning and locate the Tuning pane. 2. Check that Lead Circuit is deselected. The default is selected. 3. From the main menu select Advanced Configuration settings and locate the Droop box. 4.

After initial configuration the CAN data is available on the J1939 Diagnostics Messages view on the GAConfig Tool, or using a compatible controller. Sample PGN transmit and receive codes are shown in this section. This docu- ment is not intended to describe how to communicate with this controller over SAE J1939. CREATING J1939 MESSAGING J1939 messaging between the EEG7000 and the J1939 source is configured using these basics rules. • J1939 indexing starts at 1, not 0. • Timeout rate is 2x transmission rate. Transmission rate is configured using SPN3349 (PGN65251), part of the TSC1 message. Timeout rate defaults at the 5th byte (0xFE to 40 ms). Other values including SPN3344 can be used to set longer timeouts. • Speed Ramping is used under one of two conditions: • When not under TSC1 control • When under TSC1 control and CAN Speed Ramp Enable is set • The following lists supported PGNs. If signal is lost to J1939 the EEG7000 reverts to hardwired fixed speed settings (idle).

Enhanced Electronic Governor EEG7000 with GAConfig Tool 8-2021-D6 PIB1009 Additional EEG7000 capabilities 16 Light Force Governing provides finer adjustment resolution for smaller actuators. It is designed to work with low current small actuators, like T1 ATB, ALR/ALN, 100/103/104 series and normally closed Cummins EFC actuators. Select Light Force Governing from the Engine Tuning  Tuning menu when using small actuators to improve adjustments as they respond very quickly to input changes over a smaller range of operating current, using a fraction of the PID and current output of a normal actuator. Lead Circuit (default is ON) enables the speed controller to be more responsive and typically increases the range of gain adjustment. This function allows for more active control to increase the performance in typically slow engines. Idle is set with Speed 1 of the speed control settings on the Engine Tuning menu. Smoke Reduction is an adjustment made using the Start Fuel parameter in the Engine Tuning menu. This sets the actuator % applied during crank in order to start easily but not too high to reduce black smoke. Auxiliary Enable enables connections to synchronizing and load sharing equipment. This allows the adjustment of the speed requests through the auxiliary input voltage, accepting a 1 - 9 V DC signal, biased at 5 V, and selectable response polarity. In response the EEG7000 will increase or decrease voltage but does not change engine speed. CAN J1939 bus device communication is supported to receive and display J1939 messages. Importing, exporting, and restoring settings The EEG7000 offers a number of GAC specific capabilities as well as helpful tools. The GAConfig Tool allows settings in the tool to be stored, shared, and imported back into the tool for use on multiple EEG7000 con- trollers. Export settings at any time while using the GAConfig Tool. To export files: 1. EEG7000 must be powered on and connected to the GAConfig Tool. 2. At the Tool bar click the Export button. The Save as dialog allows you to select the location you want to save the file. To import files: 1. EEG7000 must be turned on and connected to the GAConfig Tool. 2. At the Tool bar click the Import button. The Save as dialog allows you to select the location you want to save the file. Best practice is to export engine settings information once the engine performs as desired. Name the file using dates and intended use as part of the file name. These files are helpful when shared with the GAC support team to aid further enhancing your settings. To restore the original GAC factory settings: 1. Shut the engine off. Factory restore can be done when the engine is off but the GAConfig Tool is running. 2. Access the Quick Configuration  Advanced Configuration  System Commands menu. 3. Click Factory Restore to set the EEG7000 to its factory settings. GAC factory settings are not the same settings used on an OEM version of the EEG7000. 4. To reset just the software settings, click System Reset. Parameter settings can be created before connecting to the engine and uploaded once the connection is made. The EEG7000 must be connected to power and the PC. 1. Click the Connect button on the Main menu. The Import Configuration menu displays asking if you want to import the settings you have recently created. 2. Click Import to update the EEG7000. The progress bar displays.

DC battery power not connected. 2. Check for blown fuse 3. Low battery voltage 4. Wiring error 2 Pick-Up 3 and 12 1.0 V AC RMS min while cranking 1. Gap between speed sensor and gear teeth too great 2. Check Gap 3. Improper or defective wiring to speed sensor. 4. Resistance between 3 and Ground should be 300 to 1200 Ω. See your specific magnetic pickup data for resistance settings. This could be a defective speed sensor. 3 Actuator and Battery 1(-) and 11(+) 1.0 - 2.0 V DC while cranking 1. SPEED value set too low 2. Short/open in actuator wiring 3. Defective speed control 4. Defective actuator. See the product bulletin for the specific actuator and review your actuator manuals troubleshooting section. INSTABILITY SYMPTOM ACTION Slow Periodic An irregularity of speed below 3 Hz. (Sometimes severe) 1. Adjust P, I, and D 2. Check fuel system linkage during engine operation for: • binding • high friction • poor linkage 3. Add a small amount of droop. Non-Periodic Erratic Engine Behavior Increasing Stability reduces instability but does not totally correct it. If this is the case, there is most likely a problem with the engine itself. Check for: • engine mis-firings • erratic fuel system • load changes on the generator set voltage regulator If the GAConfig Tool is not connecting check the following on your PC or Laptop: 1. Open the GAConfig Tool. 2. Click Connect. The Select Serial Port window displays. Click Advanced Configuration arrow. 3. Select the number of the serial port the EEG7000 is plugged into. If no serial ports display call your GAC representative. 4. Check to make sure your baud rate is set to 19200 and all other settings are as show in this example. 5. If you made changes reboot the machine and try again. 6. If reboot does not see the EEG7000 please call your GAC representative. EEG7000 SYSTEM TROUBLESHOOTING 17 If the engine governing system does not function determine the fault using the following voltage tests as described in Steps 1 through 3. Positive (+) and negative (-) refer to meter polarity. • Should normal values be indicated during troubleshooting steps, then the fault may be with the actuator or the actuator wiring. • Perform test with battery power on and engine off, except where noted. • See your actuator model’s product bulletin for more information on testing the actuator.

Enhanced Electronic Governor EEG7000 with GAConfig Tool 8-2021-D6 PIB1009 SYMPTOM Response ACTION Engine Overspeed Do Not Crank. Apply DC power to the governor system. After the actuator goes to full fuel, disconnect the speed sensor at Pin 3. If the actuator is still at full fuel-speed then the controller is defective. Manually hold the engine at the desired running speed. Measure the DC voltage between Pins 1(-) and 11(+) on the speed controller. If the voltage reading is 1.0 to 2.0 V DC check for: • Speed set above desired speed • Possible defective speed controller If voltage reading is > 2.0 V DC check for: • Actuator binding • Linkage binding If the voltage reading is below 1.0 V DC check for Defective speed controller Check Flywheel Teeth value. Incorrect number of teeth in setup. Overspeed shuts down engine after running speed is reached Examine the Speed and Overspeed values for the engine Speed set too high. Overspeed set too close to Speed. Actuator or linkage binding. Speed controller defective. Overspeed shuts down engine before running speed is reached Check resistance between Pin 3 and Ground. Should be 30 to 1200 Ω. See your specific Mag- netic Pick-up data for resistance details. Overspeed set too low If the speed sensor signal is erroneous, then check the wiring. Actuator does not ener- gize fully Measure the voltage at the battery while cranking. If the voltage is less than: • 7 V DC for a 12 V DC system, or 14 V DC for a 24 V DC sys- tem check or replace battery. Momentarily connect Pins 1 and 11. The actuator should move to the full fuel position. Actuator or battery wiring in error Actuator or linkage binding Defective actuator Fuse opens. Check for short in actuator or harness. Engine remains below desired governed speed Measure the actuator output, Pins 1 and 2, while running under governor control. If voltage measurement is within 2 V DC of the battery supply voltage level, then fuel control is restricted from reaching full fuel position, possibly due to mechanical governor, carburetor spring, or linkage interference. Speed set too low EEG7000 SYSTEM TROUBLESHOOTING (CONTINUED) 17 Use the Windows Device Manager to determine the correct serial port for EEG7000: 1. In your Windows search box type Device Manager. 2.
