T
L
: Determines the period during
which the input must be set in
order to enable the permanent
light function.
T
!
: Determines the on delay for the
pre-warning time.
T
!L
: Determines the length of the
pre-warning time.
Retentivity set (on) = the status is
retentive in memory.
Output Q is set with a signal at
input Trg, and it is reset again after
a configured time has expired and
depending on the pulse width at
input Trg, or it is reset with another
signal at input Trg.
Parameter
The off-delay time T, the permanent light time TL, the on-
delay pre-warning time T!, and the pre-warning time
period T!L can be provided by the actual value of another
already-programmed function:
Analog comparator (Ax – Ay) Analog threshold trigger
(Ax)
Analog amplifier (Ax) Analog multiplexer (AQ)
Analog ramp (AQ) Mathematic instruction
(AQ)
PI controller (AQ) Up/down counter (Cnt)
Analog filter (AQ) Average value (AQ)
Max/Min (AQ) On-delay (Ta)
Off-delay (Ta) On-/off-delay (Ta)
Retentive on-delay (Ta) Wiping relay(pulse output)
(Ta)
Edge triggered wiping relay (Ta)
Asynchronous pulse generator (Ta)
Stairway light switch (Ta) Multiple function switch (Ta)
Stopwatch (Ta)
The value of “TL”, ”T”can be set/modified in parameter
mode. For information about how to modify, refer to
chapter 5.2.2, please.
Timing diagram
Output Q is set to 1 with a 0 to 1 signal transition at Trg.
If output Q = 0, and input Trg is set hi at least for the
duration of TL, the permanent lighting function is enabled,
and output Q is set accordingly.
