\\\ OPERATION
Supply voltage is continuously applied to the input. An external isolated
switch between pins 5 and 6 controls the timer. When closed, the relay ener-
gizes. Opening the switch initiates the delay period. Upon completion of the
delay period, the relay de-energizes. If the control switch recloses during the
delay period, the relay remains energized and the timer resets to zero.
NOTE: The TBD Series is available in an 8-pin SPDT and an 11-pin DPDT
configuration.

DIP SWITCH OPERATION

Digital selection of the time delay is accomplished by the use of ten (10) binary
switches, each marked with a time increment. The time periods, of which there are
R five (5) ranges, represented by each switch in the ON position is added together to
TD obtain the desired time delay. No more trial-by-error adjustments.
