Triaaer recognition

The level of the control inputs are periodically monitored by the processor. The sampling time (Ts = sample rate) is
typically Ts typ = 30 msec. The maximum monitor interval can be set to Ts max = 1 00 msec. Thus, shorter impulses,
spikes or quick AC voltages are recognized inaccurate or with a delay (undersampling). The bi-polar control inputs
evaluate both half-waves of AC voltages.

Examples for trigger settings

Ts = sample delay, Ts typ = 30 msec, Ts min = 0 msec, Ts max = 100 mseC

If the control input is ON for at least 0.6 seconds (Tdel + Ts max) and no other sequence with a higher priority is
currently running, the sequence 23 is started once. The end of the starting impulse is arbitrary.

Sequence 21 is initiated when the control input is without power for at least 0.2 seconds and no other sequence with
a higher priority is currently running. Since the control input is still low at the end of the sequence, S21 starts once
again.

24V
U INP
ov

If this control line’s (watchdog) level is not altered for a period longer than 1.0 seconds, the sequence 02 is launched.
If a sequence with a higher priority is currently running, the newly selected sequence will only be initiated after completion
of the sequence with the higher priority. Please be aware of the fact, that the truthful recognition of level alterations is
only possible when they are applied for a longer period than 1 00 msec (see trigger recognition).
