Shaker motor contactor is de-energized and the
timer resumes inactive status.
Note: Before a cleaning cycle can start by
pressing the CLEAN button, the M1 fan
contactor must have been energized for at
least 30-seconds.

an internal safety feature ensures the controller
automatically resets ready for the fan to be restarted.
Reapplying power does not require the cycle to be
completed.
