Off-delay
Short description
hen an On-delay (Page 132) is set, the output is reset when the configured time has expired.
Parameter T
Note the parameter T defaults specified in topic Time response (Page 124).
The actual value of another already-configured functions can provide the time for parameter
T. ou can use the actual value of the following functions:
Analog comparator (Page 183) (actual value Ax - Ay)
Analog trigger (Page 178) (actual value Ax)
Analog amplifier (Page 191) (actual value Ax)
Analog multiplexer (Page 209) (actual value A )
Analog ramp control (Page 212) (actual value A )
Analog Math (Page 224) (actual value A )
PI controller (Page 216) (actual value A )
Up/down counter (Page 168) (actual value Cnt)
Analog filter (Page 229) (actual value A )
Average value (Page 235) (actual value A )
Max/Min (Page 231) (actual value A )
On-delay (Page 132) (current time Ta)
Off-delay (current time Ta)
On-/off-delay (Page 138) (current time Ta)
Retentive on-delay (Page 140) (current time Ta)
Interval time-delay relay/Pulse output (Page 142) (current time Ta)

Description
Input Trg
The off-delay timer starts with a negative edge (1 to 0
transition) at input Trg (Trigger)
Input R
A signal at input R resets the on-delay time and the
output.
Parameter
The output switches off (transitions from1 to 0) when
the delay time T expires.
Retentivity:
/ No retentivity
R The status is retentive.
Output
A signal at input Trg sets . holds this state until T
expires.
