Abort Function
Abort is a is a temporary function that suspends the releasing count-down after contacts on a momentary-switch are
closed. Suspension of the releasing count-down occurs at 10 seconds. Activating the abort function prior to 10 seconds
continues the releasing count-down until the timer reaches 10 seconds.
Activating the abort function after 10 seconds causes an immediate suspension of the releasing count-down and the
timer holds at 10 seconds. The releasing count-down re-starts at 10 seconds when contacts on the momentary-switch
are opened. A releasing event occurs when the count-down timer reaches zero. An abort function overrides a manual
release function when the manual release is activated before the abort. The manual release function overrides the abort
function when the abort is activated before the manual release.

must be inserted and turned to the right. To silence the NACs, insert the Enable Control key, turn to the right and press
