2-8 Operation TP-5353 8/94
Fault Shutdowns
The generator set will shut down automatically under
the following fault conditions:
Overspeed. Unit shuts down immediately if governed
frequency exceeds 70 Hz (2100 RPM) on 50 and 60 Hz
models.
Overcrank. Shutdown occurs after 45 seconds of
continuous cranking. Shutdown occurs after 75
seconds of cyclic cranking (crank 15 seconds, rest 15
seconds, crank 15 seconds, etc., for a total of 75
seconds). Shutdown occurs after 15 seconds if engine
or starter will not turn (locked rotor).
Low Oil Pressure. Shutdown occurs 5 seconds after
fault. Low oil pressure shutdown will not function during
the first 30 seconds after start-up.
NOTE
Low oil pressure shutdown will not protect against low oil
level. Check for oil level at engine.
High Engine Temperature. Shutdown occurs 5
seconds after fault. High engine temperature shutdown
will not function during first 30 seconds after s tart-up.
NOTE
High temperature shutdown will not function if proper
coolant level is not maintained.
Low Coolant Level. Shutdown occurs 5 seconds after
fault. Low coolant level shutdown will not function during
the first 30 seconds after start-up.
NOTE
Low oil pressure, high engine temperature, and low
coolant level shutdowns will not function during the first
30 seconds after start-up.
Overvoltage (if equipped). Unit will shut down after
approximately two seconds of voltage 15% or more over
nominal voltage. Low water temperature/auxiliary lamp
will light.
NOTE
Sensitive equipment may suffer damage in less than
one second of an overvoltage condition. Install separate
overvoltage protection to on-line equipment requiring
faster shutdowns.
