Function C: Delay on break - timing after impulse

Delay OFF (with constant supply

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: Repeat cycle - Flip-flop

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: Timing on energisation

Interval timer - one shot

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.

Function B: Single shot - timing on impulse one shot

On pulse (with constant supply)

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: Pulse output (adjustable)

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.

U : Supply C (Y1) : Control contact R : Output or load relay T : Timing : indefinite

Function A: Delay on make - delay on energisation

Single timing cycle which begins on energisation.

The output changes state after timing.

Function Ab: One-shot cycle

The output changes states at the end of the set time T1, for a period T2. Both T1 and T2 independently adjustable.

Function Ac: Timing after closing and opening

of control contact

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. .

Function Ad :Delay on energisation by switch

(not resettable)

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 : Flashing single cycle by switch

(not resettable)

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: Timing on energisation with memory

Provides a cumulative time for contact opening.

The output changes states at the end of the set time.

Function P : Delayed fixed-length pulse

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.

Function Pt : Impulse counter (delay on)

Calculates the total opening time of a contact. At the end of timing, the output is energised for approximately 500 ms.

Function Q : Star-delta"

At the end of timing, the output is not energised. It remains "open" (not conducting) and will only change state after the fixed time of Ti has elapsed. Dwell time selectable

Function T : Timing on

energisation with memory 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

Function T : Impulse relay

After power-up, pressing or holding down the switch closes the relay. Pressing the switch a second time opens the relay.

Function Tt : Timed impulse 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.

Function W : Timing after pulse on control contact

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.

Function L : Repeat cylce - Cyclic timing - Asymmetrical recycler

Repetitive cycle comprising 2 independent adjustable time bases. Each time base corresponds alternately to a different output state.

N.B. : The cycle starts with the output in the rest position.

Function Li : Repeat cylce - Cyclic timing - Asymmetrical recycler

Repetitive cycle comprising 2 independent adjustable time bases. Each time base corresponds alternately to a different output state.

N.B. : The cycle starts with the output in the operating position.

Function N : "Safe-guard"

At the first control pulse the output is energised. To complete the timing the interval between the two control pulses must be greater than the timing set.

Function O : "Delayed safe-guard".

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.

Function Ht : Delay on energisation

with memory

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.

Function K: Delay on de-energisation - True delay OFF

On energisation, the output changes state. On de-energisation timing commences and the output only returns to the reset condition after timing.
