Complementary information
•
If there are objects in the area of the muting sensors during the first logic cycle
and therefore one or more muting sensor signal inputs are set to 1, this gener‐
ates a muting error. The signaling of the error state at the
Muting error
output is
suppressed if the
BWS
input = 1. Before a new valid muting cycle can be executed,
this error must be reset.
•
The muting times have an accuracy of ± 10 ms (evaluation plus logic execution
time).

The optional
C1
input can be used as additional protection against
manipulation. If it is used, the
C1
input must have switched to 0 after a
previous muting cycle, and to 1 at the latest when both muting sensor
signal inputs switch to 1 at the same time. A failure to meet this
condition results in a muting error, which is indicated at the
Muting error
output.
The
C1
input must then switch back to 0 before the subsequent muting
cycle is permitted. The
C1
input is not relevant for the duration of the
muting status.
