Condition
AC sensing lost. In Auto mode, generator output AC sensing
is lost. Detection begins10 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
W
circuit) on the accessory controller power output.
Shutdown during the reduced speed portion of an exercise.
The event history will show Advanced Diagnostic Active. The
SD engine then restarts, runs at full speed for 2 minutes, and
stops. The controller returns to AUTO mode. The exercise
schedule does not change.
ATS communication error. Warning is displayed if ATS
W interface connection is lost. See the section title: ATS
Communication Errors.
ATS phase rotation mismatch. Transfer switch phase rotation
W
does not match, ATS will not transfer.
Auxiliary input. An optional customer-connected input is
closed. (Digital input from optional PIM.)
Battery charger fault. Input to PIM from an external battery
W
charger (not the built-in battery charger).
Engine starting battery voltage falls below 11 VDC for more
than 10 seconds. Inhibited during the engine crank cycle.
W
Clears when the battery voltage returns to an acceptable
level.
Engine starting battery voltage rises above 16 VDC for more
than 10 seconds. Inhibited during the engine crank cycle.
W
Clears when the battery voltage returns to an acceptable
level.
Engine starting battery voltage falls below 12.5 VDC for more
than 90 seconds when the engine is not running. Not
W operative during the engine crank cycle.
Clears when the battery voltage returns to an acceptable
level.
