F.5.4.1.5 Manually Starting/Ending a Nomination Period
When a Nomination Period is not in progress, the user can immediately begin the NEXT
period by setting the Status signal to the ON state. The current start time will reflect the
time that the user started the cycle. The target and stop times used will be those of the
NEXT period. The user may immediately end a nomination period which is in progress by
setting the Status signal to the OFF state. The current time will be stored as the LAST stop
time.
