(continuous light), or reset Q with off delay. Output Q can
be reset with a signal at the Trg input.
Input R You set the current time Ta, and reset the output to 0, with
a signal at input R.
Parameter T: The output is reset (1 to 0 transition) when the time T
has expired.
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 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 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
＂Ｔ＂，＂ＴＬ＂
can be set/modified in parameter mode.
