Total Power High ShtDwn SD Measured load is greater than 102% of
the generator set power rating for more
than 1 minute. (38RCL only)
Reduce the load by
disconnecting non-essential
equipment. Check wiring and
troubleshoot connected
equipment.
Check for phase imbalance.
Check for very high power
factor loads.
Volts L1-L2 High Shutdwn [ Shutdown The controller shut down the generator
because the voltage measured from
Phase A to Phase B exceeded the high
limit for a time greater than the delay
setting 2 seconds.
Troubleshoot alternator; see
alternator service manual.
Volts L1-L2 Low Shutdwn [ Shutdown The controller shut down the generator
because the voltage measured from
Phase A to Phase B was greater 5% of
rated, but less than the low voltage
setting for a time greater than the delay
setting 10 seconds.
Troubleshoot alternator; see
alternator service manual.
Volts L2-L3 High Shutdwn [ Shutdown The controller shut down the generator
because the voltage measured from
Phase B to Phase C exceeded the high
limit for a time greater than the delay
setting 2 seconds.
Troubleshoot alternator; see
alternator service manual.
Volts L2-L3 Low Shutdwn [ Shutdown The controller shut down the generator
because the voltage measured from
Phase B to Phase C was greater 5% of
rated, but less than the low voltage
setting for a time greater than the delay
setting (default 10 seconds).
Troubleshoot alternator; see
alternator service manual.
Volts L3-L1 High Shutdwn [ Shutdown The controller shut down the generator
because the voltage measured from
Phase C to Phase A exceeded the high
limit for a time greater than the delay
setting. (default delay time is 2
seconds.)
Troubleshoot alternator; see
alternator service manual.
Volts L3-L1 Low Shutdwn [ Shutdown The controller shut down the generator
because the voltage measured from
Phase C to Phase A was greater 5% of
rated, but less than the low voltage
setting for a time greater than the delay
setting.
Troubleshoot alternator; see
alternator service manual.
