Section 2 Generator Set Operation
Condition
AC Sensing Lost. In Auto mode, generator
output AC sensing is lost. Detection begins 10
seconds after crank disconnect.
Warning: after 1 second if no output detected
after crank disconnect.
Shutdown: after 3 seconds if voltage was
present and then lost.
Accessory Power Overload. An over current
fault (short circuit) on the accessory controller
power output.
ATS Communication Error. Warning is
displayed if RXT interface connection is lost.
See Section 2.6.3.
ATS Phase Rotation Mismatch. Transfer
switch phase rotation does not match. ATS will
not transfer.
Auxiliary Input. An optional
customer-connected input is closed. (Digital
input from optional PIM.)
Engine starting battery voltage falls below 11
V for more than 10 seconds. Inhibited during
the engine crank cycle.
Clears when the battery voltage returns to an
acceptable level.
Engine starting battery voltage rises above
133% (16 V) of the battery voltage setting for
more than 10 seconds. Inhibited during the
engine crank cycle.
Clears when the battery voltage returns to an
acceptable level.
Engine starting battery voltage falls below the
battery voltage setting (typically 12.5 volts) for
more than 90 seconds when the engine is not
running. Inhibited during the engine crank
cycle.
Clears when the battery voltage returns to an
acceptable level.
The time and date have not been set on the
generator controller.
The coolant level switch input has been
activated.
Coolant temperature is too high.
Crankshaft Position Sensor (CPS) timeout
error occurred.
This group of faults includes a wide variety of
faults that originate from the engine ECM
and also contain ECM in the fault name.
