Problem 5
The engine shutdown occurs after the engine runs for more than 3 minutes.
Check the overspeed setting on the electronic speed switch (ESS).
Observe the indicator lamp on the ESS.
Reset the air shutoff lever, if equipped.
Crank the engine. Stop the engine with the emergency stop switch, if trouble occurs.Result
The indicator lamp on the ESS is turned on.Overspeed is indicated as the cause of the engine shutdown. Press the "RESET" button of the ESS. Find the cause of the overspeed. Refer to Testing and Adjusting, "Overspeed Verification Test" and Testing and Adjusting, "Overspeed Calibration". If the overspeed is adjusted properly and the problem persists, check the shielded cable. Only the shield should be connected to terminal 2 on the ESS. STOP.
The indicator lamp is turned off.Go to Step 2.
Check the protection switches.
Remove the jumper that is between terminals (TS-9) and (TS-10) of the junction box.
Crank the engine. Stop the engine with the emergency stop switch, if trouble occurs.Result
The engine starts and the engine runs.The problem is in the oil pressure switches or the water temperature contactor switch. Go to Step 8 of "Problem 1".
The engine starts but engine shutdown occurs immediately.Go to Step 1 of "Problem 3".
The engine starts and the engine runs but engine shutdown occurs after the engine runs for more than 3 minutes.Go to Step 3.
The engine cranks but the engine does not start.Go to Step 1 of "Problem 1".
Check the start/stop switch.
Disconnect the wire in the junction box that connects terminal (SR1-85) of the slave relay (SR1) to terminal (TD-7) of the time delay relay (TD).
Disconnect the wire from terminal (TD-7) and insulate the exposed wire.
Crank the engine. Stop the engine with the emergency stop switch, if trouble occurs.Result
The engine starts and the engine runs.The start/stop switch has a short circuit or a wiring problem is causing a voltage at terminal (TD-7). Reconnect the wire to the terminal.
Check the start/stop switch.
Disconnect the wire that runs from the STOP position of terminal (SSS-6) to terminal (TD-6). Terminal (SSS-6) is on the start/stop switch.
Disconnect the wire at terminal (TD-7).
Crank the engine. Stop the engine with the emergency stop switch, if trouble occurs.Result
The engine starts and the engine runs.The start/stop switch is faulty. Replace the switch. STOP.
Engine shutdown still occurs.Reconnect the wire to terminal (TD-7). Go to Step 5
Check the slave relay (SR1).
Disconnect the wire that connects terminal (TS-10) of the junction box to terminal (TD-6) of the time delay relay.
Disconnect the wire at terminal (TD-6).
Crank the engine. Stop the engine with the emergency stop switch, if trouble occurs.Result
The engine starts and the engine runs.The start/stop switch is faulty. Replace the start/stop switch. STOP.
Engine shutdown still occurs.The contacts of SR1 periodically close. The problem may also be with the governor or the fuel supply to the engine. Refer to the Engine Service Manual. If a 2301A Electric Governor is used, the SR1 contacts may be opening. Refer to 2301A Electric Governor Service Manual, SENR3585. Test SR1. Refer to Testing and Adjusting, "Slave Relay Test".Problem 6
Engine shutdown does not occur
The engine shutdown occurs after the engine runs for more than 3 minutes.
