Description
The model 4388 is a delay-on-make timer with
the output contacts normally closed. When operating voltage is applied to a load connected
to the model 4388 the load circuit will turn ON. The load circuit will remain ON until an
initiate switch closes and a preset timing period expires. At the end of the preset timing
period the output contacts open and the load circuit is turned off. When the initiate
switch is opened, the output contacts close and the load circuit is turned back ON.
