T (bidirectional) muting timings with time monitoring
The activation of the Muting function occurs as a result of the interruption of the sen-
sors S1 and S2 (the order is not relevant) within a time of T
material moving in the opposite direction. When the delay time of T
muting function immediately stops.
NOTE: Muting operations is ceased as soon as the signal from S3 (S2 in the
opposite direction) goes inactive. An optional additional muting time Tdelay
may be set.
WARNING: If T
cuit between MUTING1 and MUTING2 input. USE ONLY if risk assessment
allows or if additional diagnostic measure are implemented (eg. Mute
Enable signal configured). ????????
