Mode of Operation
Function 1
Delay on operate
The time period starts when
pins 5 and 2 are interconnect-
ed. At the end of the set delay
the relay will operate and will
not release until pins 5 and 2
are interconnected again, or
power supply is interrupted.
The time period will autostart
when pins 5 and 2 are con-
stant connected.
Function 2
Interval timer
The relay operates and the
time period starts when pins 5
and 2 are interconnected. At
the end of the set delay the
relay releases. The relay will
operate again when pins 5
and 2 are interconnected. For
autostart connect pins 5 and
2 before power supply is ap-
plied. A recovery period of 200
ms should be allowed before
reapplying power supply.
Function 3
Interval timer
Delay on release
Power supply must be con-
stantly applied. When inter-
connecting pins 5 and 2 the
relay will operate. When pins
5 and 2 are disconnected, the
time period starts, and when
the set time period has expir-
ed, the relay releases. If pins 5
and 2 are connected again
before the time period has
expired, the time is reset and
the time period restarts when
the interconnection between
pins 5 and 2 is interrupted.
Function 4
Recycler
ON-time period first
When power supply is ap-
plied the relay operates and
the time period starts. At the
end of the first set time pe-
riod, the relay releases for the
set time period. This
sequence continues with
equal ON- and OFF-time peri-
ods until power supply is
interrupted.
Recycler
OFF-time period first
When pins 5 and 2 are inter-
connected the recycler func-
