Configurable muting functions
Additional signal C1
You can also connect an additional signal C1 to the muting sensors. The signal can be a
c
ontrol signal from a PLC or a further sensor. The additional signal C1 is not allowed to be
a static signal. It is checked for dynamic behaviour during the muting cycle. If dynamic sig-
nal behaviour is not detected, no further muting can be initiated.
The following dynamic sequence must be present at the input:
To activate muting, a LOW/HIGH signal change must occur on input C1, before both mu-
ting sensors in the first sensor pair (e.g. A1 and A2) are active. If this is not the case,
then muting is not initiated.
If muting has been initiated, then a HIGH/LOW signal change must then occur on input
C1. If this is not the case, muting cannot be initiated again.
If you activate the additional signal C1, the direction detection function is activated
automatically and cannot be deactivated.
Information on the possible combinations of additional signal C1 and on connection can
be found in section 6.10 “Combinable muting functions and facilities for connecting”
from page 63.
