Wiring Diagram
Mode 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 time 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.
