Fault Message CheckDescription/ CommentsAction
Spd Sens Flt Shutdwn
(Speed sensor fault)
Shutdown The controller shut down the generator
because the speed signal was lost.
Check leads 55, 66, F+, and
F-- between the alternator and
the controller. This fault also
occurs if the engine stalls;
check the engine and see the
troubleshooting chart in
Section 4.11.
Total Power High Shutdwn Shutdown Measured load is greater than 102% of
the generator set power rating for more
than 1 minute. (10/12RESV 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
Section 4.11, Troubleshooting
Charts, and Section 5,
Component Testing and
Adjustment.
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
Section 4.11, Troubleshooting
Charts, and Section 5,
Component Testing and
Adjustment.
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
Section 4.11, Troubleshooting
Charts, and Section 5,
Component Testing and
Adjustment.
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
Section 4.11, Troubleshooting
Charts, and Section 5,
Component Testing and
Adjustment.
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
Section 4.11, Troubleshooting
Charts, and Section 5,
Component Testing and
Adjustment.
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
Section 4.11, Troubleshooting
Charts, and Section 5,
Component Testing and
Adjustment.
