S 1201 156, S 1201 166
Mode of Operation
Delay on operate
The time period starts when
power supply is applied. At the
end of the set time period, the
relay operates and does not
release until power supply is
interrupted for at least 200 ms.
Interval timer
The relay operates and the
time period starts when power
supply is applied. At the end
of the set time period, the relay
releases. Operation starts a-
gain when reapplying power
supply after an interruption of
at least 200 ms.
Symmetrical recycler
ON-time period first
When power supply is applied
the relay operates and the
time period starts. At the end
of the first set time period, the
relay releases. At the end of
the second set time period (of
the same duration as the first),
the relay operates again.
This sequence continues with
equal long ON- and OFF-time
periods until power supply is
interrupted.
Symmetrical recycler
OFF-time period first
The time period starts when
power supply is applied. At the
end of the first set time period,
the relay operates. At the end
of the second set time period
(of the same duration as the
first), the relay releases.
This sequence continues with
equal long OFF- and ON-time
periods until power supply is
interrupted.
