Section
AF Auxiliary fault Not used on the model 8.5/12RES. — —
HE High engine
temperature Shutdown occurs if the engine coolant
temperature exceeds the maximum temperature
for more than 5 seconds. This protective
becomes active after the engine reaches the
crank disconnect speed. Check for blocked air inlets and exhaust outlets. 1.8
LCL Low coolant
level Not used on air-cooled models. — —
LOC Loss of coolant Not used on air-cooled models. — —
LOP Low oil
pressure Shutdown occurs if a low oil pressure condition
exists for more than 5 seconds. This protective
becomes active 30 seconds after the engine has
reached crank disconnect speed (30 second
inhibit).
Note: The low oil pressure shutdown does not
protect against low oil level. Check the oil level
at the engine.
Check for leaks in the lubrication system.
Check the oil level and add oil if the level is low.
Check low oil pressure switch connections and
operation.
Check the oil pump and lubrication system.

OC Overcrank Shutdown occurs after 3 unsuccessful starting
attempts. The crank cycle is set for three
starting attempts of 15 seconds cranking and 15
seconds rest. Check the fuel supply valves and pressure.
Check spark plug and battery.
See Troubleshooting Chart, generator set cranks
but does not start.

The generator set shuts down on an overcrank
fault if no engine rotation is sensed. Shuts down
after 3 seconds of cranking or 1 second after the
fault is detected. Check mag pickup connections and operation.
Check for a locked rotor.

OF Overfrequency Shutdown occurs when the governed frequency
exceeds 110% of the system’s frequency

setpoint for more than 5 seconds. This
protective becomes active 10 seconds after
engine start (10 second inhibit).
Measure output frequency and ajdust, if
necessary. 5.8.5
engine start (10 second inhibit).
Check governor system condition and operation. 5.8
OS Overspeed Shutdown occurs if the engine speed exceeds
115% of the normal running speed for more than
0.3 seconds. Check governor settings and operation. 5.8
OU Overvoltage Shutdown occurs if the voltage exceeds 120% of
the system nominal voltage for more than 2
seconds. Check AC voltage.
Check wiring and connections.

UF Underfrequency Shutdown occurs when the governed frequency
falls blow 90% of the nominal system frequency
for more than 5 seconds. This protective
becomes active 10 seconds after engine start.
