Description
The model 4888 is an electronic timing device which controls a solid state switch in a delay-on-make and break mode of
timing. When operating voltage is applied, the timer is in a standby condition until an
initiate switch closes. When the initiate switch closes the delay-on-make timing period
begins. At the end of this period the output load energizes and remain energized for as
long as the initiate switch is closed, and for preset delay-on-break timing duration after
the initiate switch opens. Should the initiate switch close during preset delay-on-break
timing period, the output will remain energized and the timing period, the output will
remain energized and the timing period reset to zero. Both timing periods are adjusted by
integral potentiometers atop the timer.
