The timing period T begins on energization. After timing, the output(s) relay close(s).
2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)
After power-up, closing of the control contact Y1 causes the timing period T to start (timing can be interrupted by operating the Gate control contact G). At the end of this timing period, the relay closes.
When control contact Y1 re-opens, the timing T starts.At the end of this timing period T
At the end of this timing period T, the output reverts to its initial position (timing can be interrupted by operating the Gate control contact G).
2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)
After power-up, the first opening of control contact Y1 starts the timing. Timing can be interrupted each time control contact closes. When the cumulative total of time periods elapsed reaches the pre-set value T, the output relay closes.
T = t1+t2+t3
After power-up, pulsing or maintaining control contact Y1 starts the timing T. The output relay closes for the duration of the timing period T then reverts to its initial state.
On closing and opening of control contact Y1, the output relay closes for the duration of the timing period T.
After power-up and closing of the control contact Y1, the output relay closes. When control contact Y1 re-opens, timing T starts. At the end of the timing period, the output(s) relay revert(s) to its/their initial state.
2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)
Repetitive cycle with two timing periods T of equal duration, with output(s) relay changing state at the end of each timing period T.
Before power-up Y1 should be permanently connected to A1.

Repetitive cycle with two timing periods T of equal duration, with output(s) relay changing state at the end of each timing period T.
2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)
On energization of the relay, timing period T starts and the output(s) relay close(s). At the end of the timing period T, the output(s) relay revert(s) to its/their initial state

On energization, the output relay closes for the duration of a timing period T then reverts to its initial state.
Pulsing or maintaining control contact Y1 will again close the output relay.
Timing T is only active when control contact Y1 is released and so the output relay will not revert to its initial state until after a time t1 + t2 + t3
The relay memories the total, cumulative opening time of control contact Y1 and, once the set time T is reached, the output relay reverts to its initial state.
