• Range D:
The Stop coil is inoperative after the time has elapsed.
• Range E:

Timing relay, off-delayed with and without random
switching
Random switching, with and without retriggering
The contact of the timing relay randomly switches within the
set value range.
Retriggering
When the time is running and the trigger coil is reactivated or
deactivated, the actual value is reset to zero. The set time of
the timing relay is timed out once more.
