Mode of Operation
A1 & Y2 not connected (F)
Function switch in position
1 (delay on operate, pulse
start)
The delay period begins when
power supply is applied and
A1 & Y1 are initiated by a con-
tact.
At the end of the set delay the
relay operates and will not re-
lease until power supply is in-
terrupted for at least 200 ms.
A new time period can be ob-
tained by disconnecting and
subsequently reconnecting
A1 & Y1.
Function switch in position
2 (pulse-controlled interval
timer)
Power supply must be con-
stantly applied.
When A1 & Y1 are initiated by
a contact, the relay operates.
The time period starts when
A1 & Y1 are disconnected.
When interconnecting A1 &
Y1 before the delay has ex-
pired, the time is reset to zero.
The time period restarts when
the interconnection between
A1 & Y1 is interrupted again. A
new time period can be ob-
tained by disconnecting and
subsequently reconnecting A1
& Y1.
Function switch in position
3 (pulse controlled delay on
operate/delay on release)
Power supply must be con-
stantly applied.
The delay period begins when
A1 & Y1 are interconnected.
At the end of the delay period
the relay operates.If A1 & Y1
are disconnected before the
time delay has expired, the
relay operates immediately,
and a new delay period starts.
After this delay the relay re-
leases.
When A1 & Y1 are discon-
nected, a new delay period
starts and when this delay
period has expired, the relay
releases.
If A1 & Y1 are interconnected
before the delay period has
expired, the relay releases im-
mediately, the time is reset to
zero and a new delay period
must expire before the relay
operates.
A1 & Y2 connected (F)
Function switch in position
1 (pulse-started interval ti-
mer, leading edge)
The relay operates and the
time period starts when power
supply is applied and A1 & Y1
are initiated by an impulse or a
contact.
At the end of the set delay the
relay releases. A new time pe-
riod can be obtained by dis-
connecting and subsequently
reconnecting A1 & Y1.
Function switch in position
2 (pulse-started symmetri-
cal recycler, ON-time first)
The relay operates and the
time period starts when power
supply is applied and A1 & Y1
are initiated by an impulse or a
contact.
At the end of the first time pe-
riod the relay releases. When
the second time period (equal
to the first) has expired, the
relay operates.
This sequence continues with
equal ON- & OFF-time peri-
ods until power supply is in-
terrupted.
By applying a new impulse
when the sequence is running,
the sequence will restart.
Function switch in position
3 (pulse-started interval ti-
mer, trailing edge)
When power supply is appli-
ed and A1 & Y1 are intercon-
nected, the relay operates
when A1 & Y1 are disconnec-
ted (triggered on trailing edge)
and the delay period starts.
When the delay period expires,
the relay releases and will not
operate again before A1 & Y1
have been interconnected and
then disconnected.
If A1 & Y1 are interconnected
before the delay period has
expired, the relay releases.
When A1 & Y1 are then dis-
connected again, the relay
operates, and a new delay pe-
riod must expire before the
relay releases again.
