Functions
U : Supply
R : Output or load relay
T : Timing
Function A:
Function Ab:
The output changes states at the end of the
set time T1, for a period T2.
Both T1 and T2 independently adjustable.
Function Ad :
The output changes state after timing.
Single timing cycle which begins on
energisation.
Function Ac:
After energisation, closure of the control
contact causes the timing period T to
commence and output relay R (or the load)
changes state at the end of this interval.
When contact C (Y1) opens, relay R resets
after a second timing period T. .
After power-up, pressing or holding down
the switch starts timing. At the end of timing,
the output is energised. The output
will be reset the next time the switch is
pressed or held down.
Function Ah :
After power-up, pressing or holding down
the switch starts timing. At the end of timing,
the output is energised. At the end of this
second timing, the output falls back to
its initial value.
Function At:
Provides a cumulative time for contact
opening.
The output changes states at the end of the
set time.

AOutput relay R (or the load) changes state,
and remains in the changed-over state for the
timing period, both when control contact C
(Y1) closes and when it opens.
Function B:
After energisation; a pulse ( 50 ms) or a
maintained control contact will cause the
output to change state which reverts to the
rest position at the end of timing.
N.B. : this process enables shortening or
lengthening of a signal.
Function Bw:
Function C:
After energisation, once the control contact is
closed the output state changes.
Timing will only begin on the re-opening of
this control contact (one shot).
Relay R returns to its initial position at the
end of the timing period.
Function D or Di:
Repetitive cycle which switches the output
alternately between the rest and operating
position for equal time bases.
T1 + T2 = T total
Function D: the cycle begins with the output
in rest position. Pause start.
Function Di: the cycle begins with the output
in the operating position. Pulse start.
Function H:
On energisation, the output changes state,
remains in that state for the duration of timing
and resets at the end of the single cycle.
N.B. This is complementary to function A.
