Mode of Operation
The delay period begins when
power supply is applied. At the end of the set delay, the
relay will operate 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 cir-
cuit is reset to zero, and the
relay is ready for a new time
period.
