Provides a cumulative time for contact opening.
On energisation, the output changes state,
remains in that state for the duration of timing
and resets at the end of the single cycle.
On energisation, the output changes state.
On de-energisation timing commences and
the output only returns to the reset condition
after timing.
Repetitive cycle comprising 2 independent
adjustable time bases. Each time base corre-
sponds alternately to a different output
state.
N.B. : The cycle starts with the output in the
rest position.
Repetitive cycle comprising 2 independent
adjustable time bases. Each time base corre-
sponds alternately to a different output
state.
N.B. : The cycle starts with the output in the
operating position.
At the first control pulse the output is ener-
gised.
To complete the timing the interval between
the two control pulses must be greater than
the timing set.
On energisation, a first timing sequence
occurs and the output changes state.
With the closing of the control contact, the
output resets and the timing starts, with the
output being activated after timing.
For the timing to be completed, the interval
between the closing of two control contacts
must be greater than the timing set.

Calculates the total opening time of a contact.
At the end of timing, the output is energised
for approximately 500 ms.
After power-up, pressing or holding down the
switch closes the relay. Pressing the switch a
second time opens the relay.
After power-up, pressing or holding down the
switch closes the relay and starts timing. The
relay opens at the end of timing or when the
switch is pressed a second time.
Timing begins on energisation. At the end of
the timing period output relay R (or the load)
changes state for a period of approx. 500
milliseconds.
At the end of timing, the output is not
energised. It remains "open" (not con-
ducting) and will only change state after
the fixed time of Ti has elapsed.
Dwell time selectable
a - energisation by control signal
The timer sums the times for which the
control contact is closed (C1).
Reset is by the reset signal (C2) only.
b - energisation by supply voltage
The timer sums the times for which the
supply voltage (U) is on.
Reset is by the reset signal (C2) only
After energisation, if the control contact
opens it causes output relay R (or the load)
to change state and timing to start. At the
end of the timing period, relay R resets to its
original state.
