4.2.5 Auto exercise
You can use exercise mode to schedule a maximum of two start/stop sequences for the genset. The sequences can occur
daily, weekly, or monthly. The load transfer on the mains/genset is also configurable.
The exercise mode is activated when a scheduled sequence starts. The scheduled sequence only starts if there are no
alarms. The sequence runs for the adjustable DG ON duration time. When the DG ON duration timer expires or when you
push the Stop button, the engine cools down and then stops. The controller is no longer in exercise mode when the engine
has stopped. If you have scheduled two sequences to start at the same time, a minute is added to the start time for the
second sequence.
The genset does not start if a sequence is scheduled to start when the controller is in manual mode. If you change the
running mode to AUTO mode during a scheduled sequence, the genset starts and operates for the remaining duration time.
If the controller is in AMF mode when a sequence is scheduled to start, the controller changes to exercise mode for the DG
ON duration time. The controller returns to AMF mode once the DG ON duration has expired. If a mains failure occurs during
a scheduled sequence (exercise mode), the genset continues to run for the DG ON duration time, and then returns to the
AMF mode. Load is then transferred to the genset. When the mains returns, the genset cools down and stops.
