C (y1) : Command
• A function:
Delay on energisation
1 relay
Single shot timing which starts
on energisation.
• Ad function:
Delay on energisation
(cannot be reset)
1 relay
After ener
gisation, a control pulse
or latching contact starts timing.
At the end of timing, the output
is excited. The output will be reset
when a new control pulse or
latching contact occurs.
• Ac function:
Timing after closing and opening
of control contact
1 relay
After energisation, closing of the
control contact results in starting
of the time delay T.
Output relay "R" (or the load)
changes state at the end of
this time delay. After opening of
contact C (Y1), relay "R" drops out
after a second time delay T.
• At function:
Timing on energisation
with memory
1 relay
Adds up the opening time
of a contact.
Output relay "R" (or the load)
changes state at the end of timing.
• A1 function:
Delay on energisation
1 timer
1 instantaneous relay
• A2 function:
Delay on energisation
2 timers.
• AM function:
Delay on energisation
Latching during the time delay.
• AMt function:
Delay on energisation
Latching during and after
the time delay.
• B function:
Timing on impulse (one shot) -
Shaping (cannot be reset)
1 relay
After energisation, an impulse
≥
50
(
ms) or a latching contact
causes a change in state of the
output relay "R" (or the load)
which drops out at the end
of timing.
• Bw function:
Pulse output (adjustable)
1 relay
On closing and opening
of the control contact C (Y1),
the output relay "R" (or the
load) changes state for as long
as the time delay lasts.
2 timers or
2 relays including 1 instantaneous
• C function:
Timing after impulse
True delay off
(without auxiliary power supply)
1 relay
After energisation, closing of the
control contact C (Y1) results in
the change of state of output relay
"R" (or the load).
Timing will only start when this
contact opens.
• D or Di functions:
Symmetrical flashing
Repetitive cycle which alternately sets the output relay "R"
(or the load) to operating and rest position for equal periods
of time.
1 relay
1 relay
D function:
The cycle starts with relay
"R" in rest position.
Di function:
The cycle starts with relay
"R" in operating position.
• Ah function:
Single shot flip-flop
(cannot be reset)
After energisation, a control pulse
or latching contact starts timing.
At the end of timing, the output is
excited. The time delay is then
reset. At the end of this new time
delay, the output reverts to its initial
value.
2 timers or
2 relays including
1 instantaneous
