Description of the function
Output Q is set to 1 with a 0 to 1 signal transition at input Trg. The 1 to 0 transition at input
Trg triggers the current time and output Q remains set.
Output Q is reset to 0 when Ta reaches the time T. Before the off delay time (T - T
Output Q is reset to 0 when Ta reaches the time T. Before the off delay time (T - T
!
) has
expired, you can output a prewarning that resets Q for the duration of the off prewarning time
T
!L
.
Ta is retriggered (optional) at the next high/low transition at input Trg and if Ta is expiring.

● Switch (continuous light)
● Pulse switch with off delay
● Switch (continuous light)
Connection
Description
Input Trg
A signal at input Trg (Trigger) sets output Q (permanent light) or resets Q with an
off-delay. When active, output Q can be reset with a signal at input Trg.
Input R
A signal at input R resets the current time Ta and resets the output.
Parameter
T : determines the off-delay time. The output is reset (1 to 0 transition) when the
time T expires.
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 prewarning time.
T
!L
: determines the length of the prewarning time period.
Retentivity 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.
