Mode of Operation
The delay period begins
when
power supply is
applied. At the end of the
set delay, the relay will oper-
ate and will not release until
power supply is interrupted
for at least 200 ms. If power
supply is interrupted for at
least 200 ms before the relay
operates, the time circuit is
reset to zero and the relay is
ready for a new time period.
