range muting sensors so that the muting signals arrive at the device at different
times
Important information
NOTE
If a mut
ing connector is used or one signal is on the system connection and the 2nd
signal on the extension connection, the muting sensors do not have to be arranged with
an offset.

4.3.6.5 Partial blanking
In comparison to muting, the partial blanking function allows safety to be increased by
ha
ving the topmost beam (far from system plug) remain active during a valid muting
condition. All other beams are temporarily bypassed (e.g. for a certain object height). As
soon as the topmost beam is interrupted, the OSSDs switch to the OFF status.

Inactive beams
The following is true for partial blanking:
•
T
he active beam can be bypassed by override even if partial blanking is configured
•
Partial blanking cannot be combined with a reduced resolution
4.3.6.6 Distributing muting signals
In the regular configuration, the muting signals are at In1 and In2 of the extension
c
onnection. If both muting signals are actuated, muting is active.
However, if a muting signal is to be supplied by the control system, muting signal 1
can be moved from In1 of the extension connection to In4 of the system connection
(system plug SP2 M12, 8-pin). Once the muting sensor is actuated and the control
system supplies a signal, muting is active. EDM is then not possible on the system and
extension connection.
