Timing Sequence
Timing Operation:
Control signal (S) applied – timing period T1 starts.
After preset time T1 – output (R) closes.
Output (R) remains closed for preset time T2.
After time T2 – output (R) opens.
Output (R) remains open until next control signal (S) is applied, which retriggers the sequence.
