Action Description/ Comments
Warning The digital input for Low Fuel Level
Warning (PIM) is active (low).
Warning There is voltage at the generator set but
no voltage measured on the emergency
side of the ATS (Model RXT transfer
switch).
Warning The digital input for Ground Fault
Warning (PIM) is active (low).
Warning Generator serial number parameter not
populated or is invalid.
Warning The ECM reported that the engine
manifold air temperature is too high.
Warning The ECM reported that the signal
(voltage) from the manifold air
temperature sensor is too high.
Warning The ECM reported that the signal
(voltage) from the manifold air
temperature sensor is too low.
Warning During cranking, the controller
measured battery voltage less than
60% (7.2V or 14.4V) for 6 seconds or
more during cranking.
Shutdown The controller shut down the generator
because no rotation of the engine or
alternator was detected, for 3 seconds
or more, during cranking.
Shutdown The internal current limit circuit has
tripped, indicating an overcurrent
condition on the DC power supply
circuit.
Warning Engine run time, or calendar days, has
exceeded the maintenance reminder
setting.
Warning The RDC2 controller is not in AUTO.
The generator will not start from an ATS
or remote device.
The digital output for Not In Auto (PIM)
is active (contacts closed).
Check
Check customer equipment
connected to the PIM module.
Check line circuit breaker.
Check for and correct short
circuits or overloading on the
load side before resetting the
circuit breaker.
Check customer equipment
connected to the PIM module.
If available, reenter the
correct or valid Serial
Number.
Use SiteTech to load the
saved parameter file for this
generator.
Clean debris.
Check engine compartment
fan wiring.
Check engine compartment
fan fuses. Reconnect intake
air duct.
Check the TMAP sensor for
shorted leads.
Check the TMAP sensor for
shorted leads.
Check cranking battery.
Check cranking circuit.
Check for loose connections.
Check for obstruction of
alternator or engine.
Troubleshoot the engine. See
Engine Service Manuals.
Check alternator connections
to controller and auxiliary
winding circuit breaker.
Troubleshoot the alternator.
Check crank, run, and flash
relay circuits for short circuits.
Change the oil and perform
other service according to the
service schedule in
Section 2.2.
Reset the maintenance timer
after service.
See Section 2.3.4.
