SICK Flexi Compact User Manual

Complementary information
•
If t
here 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).

Data type: Boolean
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.
