TP-6811 7/1664 Section 5 Troubleshooting
Fault Message CheckDescription/ CommentsAction
Engine Speed Low Shutdwn Shutdown The controller shut down the generator,
after crank disconnect, because engine
speed, as calculated from AC
frequency, was below the low speed
setting for 3 seconds or more.
Troubleshoot engine
operation per the engine
service manual.
Exer Not Sch Warning Warning There is no exercise scheduled. Set the exercise schedule.
Frequency High Shutdwn Shutdown The controller shut down the generator
because the frequency measured on
Phase A exceeded the high frequency
setting for 10 seconds, 10 seconds or
more after crank disconnect.
Troubleshoot engine
operation per the engine
service manual.
Frequency Low Shutdwn [ Shutdown The controller shut down the generator
because the frequency measured on
Phase A was less than the low limit for
10 seconds or the measured frequency
was 10 Hz or more less than rated for
60 seconds or more, 10 seconds or
more seconds after crank disconnect.
Troubleshoot engine
operation per the engine
service manual.
Fuel Leak Shutdwn * Shutdown The controller shut down the generator

Level Wa rning (PIM) is active (low).
Check customer equipment
connected to the PIM module.
Fuel Level High Warning * Warning The digital input for High Engine Fuel
Level Wa rning (PIM) is active (low).
Check customer equipment
connected to the PIM module.

because the digital input for Low Fuel
Level Shutdown (PIM) was activated
(low).
Check customer equipment
connected to the PIM module.
Fuel Level Low Warning * Warning The digital input for Low Fuel Level
Warning (PIM) is active (low).

GenBrkerOpen Warning
(Generator Circuit Breaker
Open)
Warning There is voltage at the generator set but
no voltage measured on the emergency
side of the ATS (Model RXT transfer
switch).
Check line circuit breaker.
Check for and correct short
circuits or overloading on the
load side before resetting the
circuit breaker.
Ground Fault Warning * Warning The digital input for Ground Fault
Warning (PIM) is active (low).
Check customer equipment
connected to the PIM module.
Lo Crank Vlt Warning Warning During cranking, the controller
measured battery voltage less than
60% (7.2V or 14.4V) for 6 seconds or
more during cranking.
Check cranking battery.
Locked Rotor Shutdwn Shutdown The controller shut down the generator
because no rotation of the engine or
alternator was detected, for 3 seconds
or more, during cranking.
Check cranking circuit.
Troubleshoot the engine. See
Engine Service Manuals.
Check alternator connections
to controller and auxiliary
winding circuit breaker.
Troubleshoot the alternator.
MainPwrOverL Shutdwn Shutdown The internal current limit circuit has
tripped, indicating an overcurrent
condition on the DC power supply
circuit.
Check crank, run, and flash
relay circuits for short circuits.
* Programmable Interface Module (PIM) required
w Load management device (LCM, load shed kit, or RXT with combined interface/ load management board).
