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, M0096722, 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.
