Trigger Inputs Pins 5 and 6,
Figures 7 and 8
Two AND-connected, identical inputs determine the
trigger conditions of monostable time stages, i.e., both
inputs must be in position “ON” so that the output is
switched ON. The tracking time starts after the trigger
conditions has elapsed. The output ON state is given until
the tracking time is over.
Input Pin 5 is a simple comparator whereas input Pin 6 is
built up as a window discriminator.
Noise suppression for t
ON
= 40 ms guarantee, that there
is no peak noise signals at the inputs which could trigger
the circuit.
At the same time, the retrigger is delayed for a duration
of 640 ms (t
OFF
), to avoid noise signal to trigger the relay.
