DELAY ON BREAK
(Off Delay, Release Delay, Delay on Release, Postpurge Delay)

OPERATION/TIME DIAGRAM

OPERATION:Power must be applied to the input before and during timing. Upon closure of the initiate switch, the output is energized (relay is transferred). The time delay begins when the initiate switch is opened (trailing edge triggered). The output remains energized during timing. At the end of the time delay, the output is de-energized. The output will energize if the initiate switch is closed when power is applied.

RESET:Reclosing the initiate switch during timing resets the time delay. Loss of power resets the time delay and output.
