5. Move the generator set master switch to OFF/
RESET.
6. Reconnect the generator set to the load using the
line circuit breaker or ATS.
Code Fault
Description
HE
High engine
Shutdown occurs if the engine coolant temperature exceeds
temperature
the maximum temperature for more than 5 seconds. This
shutdown
protective becomes active after the engine reaches the crank
disconnect speed.
LO
Low oil
Shutdown occurs if a low oil pressure condition exists for more
P
pressure
than 5 seconds. This protective becomes active 30 seconds
shutdown
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.
Overcrank
Shutdown occurs after 3 unsuccessful starting attempts. The
OC
shutdown
crank cycle is set for three starting attempts of 15 seconds
cranking and 15 seconds rest.
Locked rotor
The generator set also shuts down on OC if no engine rotation
is sensed during cranking. Shuts down 3 seconds after the
fault is detected.
OF
Overfrequency
Shutdown occurs when the governed frequency exceeds 110%
shutdown
of the system's frequency setpoint for more than 5 seconds.
This protective becomes active 10 seconds after engine start
(10 second inhibit).
OS
Overspeed
Shutdown occurs if the engine speed exceeds 110% of the
shutdown
normal running speed for more than 0.3 seconds.
UF
Underfrequency
Shutdown occurs if the governed frequency falls below 54 Hz
shutdown
for more than 5 seconds.
Shutdown also occurs if the governed frequency falls below
56.5 Hz for more than 60 seconds.
This protective becomes active 10 seconds after engine start.
(10 second inhibit).
UU
Undervoltage
Shutdown occurs if the voltage falls below 80% of the nominal
shutdown
system voltage for more than 10 seconds.
LB
Low battery
Fault code is displayed if the engine starting battery voltage
voltage warning
falls below 11 VDC for more than 30 seconds when the engine
is not running. Not operative during the engine crank cycle,
this fault condition does not inhibit engine starting.
The fault condition clears when the battery voltage returns to an
acceptable level.

7. Move the generator set master switch to the AUTO
position for startup by remote transfer switch or
remote start/stop switch.
Note: The controller's LED display remains off
until an engine start command is received.
Check
Check for blocked air inlets and
exhaust outlets.
Check for leaks in the lubrication
system.
Check the oil level and add oil if
the level is low.
Check the fuel supply, spark plug,
and battery.
Check for loose connections.
