Mode of Operation
ing the pulse period, the pulse
duration can be extended.
Shot only at supply ON (F1)
When power supply is applied,
the relay operates and will be
kept energized for the set time
period (0.15-3 s). When power
supply is interrupted, the relay will not operate.
Shot only at supply OFF (F2)
When power supply is applied,
the relay will not operate.
When power supply is interrupted, the relay operates and
will be kept energized for the
set time period (0.15-3 s).
If power supply is applied, interrupted and reapplied dur-

If power supply is interrupted,
reapplied and again interrupted during the pulse period,
the pulse duration can be extended.
Shot at supply ON & OFF (F3)
When power supply is applied,
the relay operates and will be
kept energized for the set time
period (0.15-3 s). When power
supply is interrupted, the relay operates again and will be
kept energized for the same
set time period.
If power supply is applied or
interrupted for a time period
shorter than the pulse duration, the ON- and OFF-pulses
can be extended.
