The current time Ta is triggered with a 0 to 1 signal transition at input Trg. Output Q is set to
1 when Ta reaches the time T. A further pulse at input Trg does not affect Ta.
The output and the time Ta are only reset to 0 with a1 signal at input R.
If retentivity is not set, output Q and the expired time are reset after a power failure.

The off time T can be provided by the actual value of another already-programmed function:
Analog comparator: Ax – Ay
Analog trigger: Ax
Analog amplifier: Ax
Analog multiplexer: AQ
Analog ramp: AQ
Analog math: AQ
PI controller:AQ
Data latching relay: AQ
Up/Down counter: Cnt
The value of "TL" can be set/modified in parameter mode. For information about how to
modify, refer to chapter 5 .2.2 please.

Q
Q A pulse at Trg sets Q. The output stays set until the time T
has expired and if Trg = 1 for the duration of this time. A 1
to 0 transition at Trg prior to the expiration of T also resets
the output to 0.
