Description
The model 4389 is a delay-on-make
timer with the output contacts normally open. When operating voltage is applied to a load
connected to the model 4389 the load circuit will remain Off. The load circuit will remain
Off until an initiate switch closes and a preset timing period expires. At the end of the
preset timing period the output contact close and the load circuit is turned On. When the
initiate switch is opened, the output contacts open and the load circuit is turned back
Off.
