Mode of Operation
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 re-
lay will not operate.
If power supply is applied, in-
terrupted and reapplied dur-
ing the pulse period, the pulse
duration can be extended.
Shot only at supply OFF (F2)
When power supply is applied,
the relay will not operate.
When power supply is inter-
rupted, the relay operates and
will be kept energized for the
set time period (0.15-3 s).
If power supply is interrupted,
reapplied and again interrup-
ted during the pulse period,
the pulse duration can be ex-
tended.
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 re-
lay 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 dura-
tion, the ON- and OFF-pulses
can be extended.
