Figure 117: Signal diagram of timing relay, off-delayed
(with/without random switching, with/without retriggering)
Range E: The trigger coil drops out twice.
The SET time ts consists of t1 plus t2 (switch function not retriggerable).
Range F: The trigger coil drops out twice. The ACTUAL time t1 is cleared and the SET time ts elapses
completely (retriggerable switch function).
How the timing relay works with the on/off-delayed operating mode with and
without random times
Time value I1: on-delay time
Time value I2: Off-delay time
Random switching
The contact of the timing relay switches randomly within the SETPOINT value range.
