1) Contact Y1:
Control for functions B, C, Ac, Bw, Ad, Ah, N, O, W, T, Tt.
Partial stop for functions At, Ht and Pt.
Function D if Di selected.
Not used for functions A, H and P.
Technical DescriptionFunction Ad : Pulse Delayed Relay with Control SignalDescription
After power-up, pulsing or maintaining of control contact C starts the timing T.
At the end of this timing period T, the output R closes.
The output R will be reset the next time control contact C is pulsed or maintained.Function: 1 OutputFunction Ah : Pulse Delayed Relay (Single Cycle) with Control SignalDescription
After power-up, pulsing or maintaining of control contact C starts the timing T. A single cycle then starts with 2 timing periods T of equal duration (start with output in rest position).
Output R closes at the end of the first timing period T and reverts to its initial position at the end of the second timing period T.
Control contact C must be reset in order to re-start the single flashing cycle.Function: 1 OutputFunction N : Retriggerable Interval Relay with Control Signal OnDescription
After power-up and an initial control pulse C, the output R closes.
If the interval between two control pulses C is greater than the set timing period T, timing elapses normally and the output R closes at the end of the timing period. If the interval is not greater than the set timing period, the output R remains closed until this condition is met.Function: 1 OutputFunction O : Retriggerable Interval Delayed Relay with Control Signal OnDescription
An initial timing period T begins on energisation. At the end of this timing period, the output R closes.
As soon as there is a control pulse C, the output R reverts to its initial state until the interval between two control pulses is less than the value of the set timing period T. Otherwise, the output R closes at the end of the timing period T.Function: 1 OutputFunction P : Pulse Delayed Relay with Fixed Pulse LengthDescription
The timing period T begins on energisation.
At the end of this period, the output R closes for a fixed time P.Function: 1 Output
P = 500 msFunction Pt : Pulse Delayed Relay (Summation and Fixed Pulse Length) with Control Signal OffDescription
On energisation, timing period T starts (it can be interrupted by operating the Gate control contact G).
At the end of this period, the output R closes for a fixed time P.Function: 1 Output
T = t1 + t2 + ...
P = 500 msFunction TL : Bistable Relay with Control Signal OnDescription
After power-up, pulsing or maintaining of control contact Y1 switches the output on.
A second pulse on the control contact Y1 switches the output relay off.Function Tt : Retriggerable Bistable Relay with Control Signal OnDescription
After power-up, pulsing or maintaining of control contact C switches output R on and starts timing T.
The output switches off at the end of the timing period T or following a second pulse on the control contact C.Function: 1 OutputFunction W : Interval Relay with Control Signal OffDescription
After power-up and opening of the control contact, the output(s) close(s) for a timing period T.
At the end of this timing period the output(s) revert(s) to its/their initial state.
The second output can be either timed or instantaneous.Function: 1 OutputFunction: 2 Outputs
2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.).Legend
