Wiring DiagramMode of Operation
Operation Diagram
Knob-adjustable on absolute
scale.
The relay operates immedi-
ately when power supply is
applied.
When power supply is inter-
rupted, the time period
starts, and at expiration of
the set
tim
e period the relay
releases.
If power supply is reapplied
before the relay has
released, the time is reset
and the relay remains ON.
For safe charging of the
built-in capacitor, the power
supply must be applied for
min. 20 s or 1 time period +
1 s (whichever is less).
For safe reset of the relay
(after time-out), the power
supply must be interrupted
for at least 60 s.
