Single timing cycle which begins on
energisation.
set time T1, for a period T2.
Both T1 and T2 independently adjustable.
After energisation, closure of the control con-
tact 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.
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.
Provides a cumulative time for contact
opening.
The output changes states at the end
of the set time.

After energisation; a pulse ( 50 ms) or a
maintained control contact will cause the out-
put 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.
A output 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.
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.
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.
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.
