18 Section 2 Operation
Description
Input from a customer-supplied switch that
closes when the fault is active. The generator
set shuts down 0.3 seconds after the fault is
detected and will not start when the fault is
active (input is grounded). This protection
becomes active 3 seconds after crank
disconnect.
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.
Not used.
Not used.
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).
Shutdown occurs after 3 unsuccessful starting
attempts. The crank cycle is set for three
starting attempts of 15 seconds cranking and 15
seconds rest.
The generator set also shuts down if no engine
rotation is sensed during cranking. Shuts down
1 second after the fault is detected.
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).
Shutdown occurs if the engine speed exceeds
115% of the normal running speed for more than
0.3 seconds.
Shutdown occurs if the voltage exceeds 120%
of the system nominal voltage for more than 2
seconds.
Shutdown occurs when the governed frequency
falls below 90% of the nominal system
frequency for more than 5 seconds or below 59
Hz for more than 60 seconds. This protective
becomes active 10 seconds after engine start.
(10 second inhibit).
Shutdown occurs if the voltage falls below 80%
of the nominal system voltage for more than 10
seconds.

Check
Check the cause of the auxiliary fault.
Check for blocked air inlets and exhaust outlets.

Check the fuel supply, spark plug, and battery.
Check for loose connections.
