TABLE 9-1. TROUBLESHOOTING GENSET FAULTS (CONT.)
Some genset service procedures present hazards that can result in severe personal
injury or death. Only trained and experienced service personnel with knowledge of fuels, electricity,
and machinery hazards should perform genset service. See Safety Precautions.
Accidental or remote starting can cause severe personal injury or death. Before removing a panel or
access door, disconnect the negative (−) cable from the battery to prevent the engine from starting.
WARNING
HIGH EXHAUST TEMPERATURE—CODE NO. 58
(Exhaust temperature exceeded design limits due to lack of water delivered to the exhaust/water mixer)
Corrective Action: Refer to Pages A-1 through A-5, as appropriate.
1. Check for and reconnect or replace any disconnected, kinked or leaking raw water hoses.
2. Check for and clean a blocked sea water strainer. If above the water line, fill the strainer with water
to assist priming.
3. Inspect the siphon break (if provided) for proper operation.
4. If loose, reconnect terminals S5+ and S5− to high exhaust temperature switch S5 (p. 5-8).
5. Check for a worn raw water impeller and replace as necessary (p. 4-12).
6. Clean the heat exchanger (p. 4-8).
7. Disconnect connector P1 (black) from genset controller (Page 5-1) and check continuity between
Pin 11 and terminal S5+ and between terminal S5− and B− (ground). Repair wiring and connectors
as necessary.
8. Test high exhaust temperature switch S5 and replace as necessary (Page 5-8).
9. Replace the genset controller (p. 5-1).
LOW COOLANT LEVEL—CODE NO. 59
(The engine coolant level fell below the optional coolant level sensor)
Corrective Action: Add coolant as necessary and repair leaks.
EXTERNAL SHUTDOWN—CODE NO. 61
(Genset was shut down by a fire suppression system or other external control)
Corrective Action: Make all necessary repairs to the genset and connected equipment and reset the
external control which shut down the genset.
