Lafayette 3612 Engine BB39200 - Caterpillar

throttle:
Ensure that the Engine Control Switch (ECS) is in "Local" mode.
Ensure that the PWM rotary dial lock is disengaged.
Sweep the PWM rotary throttle until the desired engine speed is within 50 rpm of the actual speed.
Ensure that the ECS contact block is closed.
Check the Sync #2 wire to the engine ECM. Use a multimeter to check if 0V is on the connector pin (C1:35).
Check the PWM output from the Speed Brick with a multimeter. The duty cycle must be between 5% and 95% on connector C1:4.
Check the analog signal to the Speed Brick. Ensure that the analog potentiometer should have a 0 kOhm to 1 kOhm resistance on pins 1, 2, and 3.
Check power supply to the Speed Brick. The Speed Brick should have a 14V to 45V supply on pins B+ and B-.
Check the "Prop Throttle Configuration" in Cat ET.
Enable the Secondary Throttle if necessary for C32 and C18.
Change the "Desired Speed Input Configuration" if the required customer setting is not PWM for C9.3.The Local Throttle Control Does Not Work (MGCP IIIB Only)
Use the following checks when troubleshooting the local control throttle:
Ensure that the Engine Control Switch (ECS) is in "Local" mode.
Ensure that the relay contacts 21 and 22 are open to the engine ECM Digital Throttle Enable input. Use a multimeter to ensure that 0V is on connector C1:37.
Ensure that the relay contacts 11 and 14 are closed to the Local Throttle Switch.
Ensure that the ECS contact block is closed.
Check the Local Control Switch for faulty wiring.
Use a multimeter to check if 0V is on connector C1:48 when the switch is pressed for "Raise Engine Speed".
Use a multimeter to check if 0V is on pin 38 when the switch is pressed for "Lower Engine Speed".
Check the auxiliary and genset throttle configurations in Cat ET.
Set the "Desired Speed Input Configuration" to "CAN" if the generator or auxiliary engine does not have a PWM speed sensor. Ensure that the "Secondary Desired Speed Input Configuration" is set to the required setting.Note: Do not set the "Desired Speed Input Configuration" and the "Secondary Desired Speed Input Configuration" to "CAN" on both inputs.Engine Does Not Start When Commanded by Automatic Start (MGCP IIIB Only)
Check the "Starter 1" cranking time under the DCU "Start/Stop/Prelube" settings in the web tool. Refer to the Programming Guide, LEBM0063, "Cat A&P Controls Programming Guide".
Check the Crank Inhibit Switch wiring. Use a multimeter to ensure that the DCU terminals 88, 89, and 90 have +24V.
Check the Cat ET configurations.
Ensure that the "Engine State Control Input Configuration" is set to "Not Installed" in the C32 auxiliary and genset engine software.
Ensure that the "Flexed Parameter - Fuel Enable Input" is set to either "Not Installed" or "Off" in the C18 auxiliary and genset engine softwareEngine Does Not Fully Shut Down After Pressing Stop Button
Check the "Hold Button to Start/Stop" setting under the DCU "Start/Stop/Prelube" menu on the web tool. Refer to the Programming Guide, LEBM0063, "Cat A&P Controls Programming Guide".The Remote Start Does Not Work
