Local Control Panel Does Not Start or Fully Shut Down Engine
Use the following checks if the engine will not start or fully shut down from the local control panel.
Check the status bar and alarm list for any alarms that have not been acknowledged. Refer to Troubleshooting Guide, M0096721, General Information.
Ensure that the physical E-Stop button is not depressed. Ensure that the remote E-Stop is not engaged.
Check that the ECS is in "Local" mode.Note: Starting from the panel is disabled if the ECS is in "Remote" mode.
Ensure that the Crank Inhibit Switch is disabled. If enabled, the status bar will display "Start Disabled".
Check that all active shutdown alarms have been acknowledged and cleared.Note: Shutdown events must be acknowledged and cleared before the engine will be allowed to start.
Check for interlocks preventing the engine from starting. There are two types of interlocks that can prevent the engine from starting. The interlocks are either programmed or physical.
Check that there are no programmed engine or transmission interlocks preventing start (such as neutral inhibit) on the "Start Conditions" screen of the DCU.
Check the "Hold Button to Start/Stop" setting if the engine attempts to start but then stops or does not fully shut down.
A dialog box will appear on the DCU if this setting is configured. The dialog box displays "Are you sure you want to start/stop the engine?". Check the "Hold Button to Start/Stop" option under the DCU "Start/Stop/Prelube" setting in the web tool. Refer to the Programming Guide, LEBM0063, "Cat A&P Controls Programming Guide".
Check the panel and engine wiring. In the panel, check the Crank Inhibit Switch wiring. Check the crank output between the DCU and remote start.Note: The remote start is for the engine ECM start command.The issue is outside of the panel if +24V is present on C-1:29 while the DCU indicates cranking. Check the E-Stop for damaged or unplugged wiring to the engine.
Use the following steps if the engine does not start and the DCU displays "Engine Start Failed":
Attempt an engine restart and monitor engine speed on the DCU.
Check the speed sensor at the flywheel housing for correct installation depth if the "Engine Speed" parameter displays "- - - -".
Perform the panel wiring troubleshooting from Step 8 if the DCU is reading engine speed.
Ensure that both the E-Stop and Crank Inhibit Switch are both disengaged if using Crank Override to start the engine.
Check the Cat® Electronic Technician (Cat ET) Service Tool configurations.The Engine Will Not Shut Down from the DCU
Use the following checks if the engine will not shut down from the DCU.
Check the Engine Control Switch (ECS) configuration. Ensure that the ECS is in "Local" mode.
Check the panel and ECS wiring. Check the DCU Relay 5K26 wiring at terminal 80. Terminal 80 should have 24V while the DCU is indicating stopping.The Local Throttle Control Does Not Work (Prop 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 rotary dial lock is disengaged.
Sweep the rotary throttle until the desired engine speed is within 50 rpm of the configured RPM value of the actual speed.
Ensure that the ECS contact block is closed.
Check the 0-5V output with a multimeter. The voltage output should be 0.5V to 4.5V, C1:S and C1:T (prop only)
Check the desired speed input configurations in Cat ET.
Enable the primary and/or secondary throttle if necessary.
Change the "tertiary desired speed" if required.The Local Throttle Control Does Not Work (Aux Only)
Use the following checks when troubleshooting the local control throttle:
Ensure that the Engine Control Switch (ECS) is in "Local" mode.
Ensure that 24V is being passed to DCU pins 22/24 when each of the raise/lower switches is depressed.
Ensure that the ECS contact block is closed.
Check the Local Control Switch for faulty wiring.
Check the desired speed input 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 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
Use the following checks if the remote start does not work.
Check the status bar. The status bar must show "Cranking Manual" or "Cranking Automatic".
If the status bar displays "Start Disabled", ensure that the crank inhibit switch is not engaged. The crank inhibit switch must be off.
If the status bar displays "Starting Denied", a shutdown event is active. The event must be acknowledged and cleared in the alarm list.
Ensure the Engine Control Switch (ECS) is in "Remote" mode.Note: Remote starting is disabled if the ECS is in "Local" mode.
Check the E-stops. Ensure that the physical E-stop button is not depressed and the remote E-Stop is not engaged.
Ensure that there are no engine or transmission interlocks such as neutral inhibit preventing start.The Remote Stop Does Not Work
If the remote stop does not work, use the following list of checks.
Check the status bar for engine states and alarms.
Ensure the Engine Control Switch (ECS) is in "Remote" mode.Note: Remote starting is disabled if the ECS is in "Local" mode.The Remote Throttle Does Not Work (Prop Only)
Ensure that the Engine Control Switch (ECS) is in "Remote" mode.Note: Remote starting is disabled if the ECS is in "Local" mode.
Ensure that the ECS contact is closed. The ECS contact must be open to enable the remote throttle.
Check PWM output from Vessel Power Train Control Throttle with a multimeter. The duty cycle must be between 10% and 90% on connector pin C1:AY.
Check the engine for PWM 1 diagnostics. Check the DCU screen for any engine PWM 1 codes.
Check for damaged or unplugged wiring from the panel to the engine ECM.Note: For a 4-20mA remote throttle input, ensure current flow and polarity between X1.1.60 and
