Function
Two-hand Monitoring for NO1*NO2 =
control inactive and NC1*NC2 = active
MEZ + time monitoring of this state.
I.e. if there is a signal change on
an NO from 1->0 or NC from 0-
>1 then the other signals (i.e.
further NO=0 or NC=1) must
follow within 0.5 s. If not the
output remains = 0.
No malfunction evaluation! No
time monitoring on change to
inactive state.
