Mode of Operation

The yellow LED, flashing
when timing, is ON as soon
as the relay turns ON.

The set delay period begins
as soon as the power supply
is connected. At the end of
the set delay the relay oper­ates and does not release

until the power supply is
interrupted for at least 200
ms. If the power supply is
interrupted for at least 200
ms before the relay operates
the time is set to zero and
the circuit is ready for a new
time period.
