PARTIAL MUTING CONFIGURATION.
This feature is available only on the F3S-TGR-SBx-K3C and F3S-TGR-SBx-
K4C models.
It gives the users the opportunity to mute only half of the light curtain. The
other half remains active.
The configuration of this function is done by setting the internal dip switches
1
& 2.
For correct configuration and identification of dip switch and bypassed optics
refer to the following drawing and table.

CRITERIA FOR INSTALLATION
Take adequate care when installing the muting sensors to prevent undesired
requests for
muting
:
1. Wiring must be done correctly.
2. The
muting
sensors must recognise the whole length of the material (i.e.
pallets, vehicles...).
3. The sensors must be arranged so that the material is also recognised if it
has to be lifted for processing.
4. The effect of various transportation speeds in the field of
muting
on the
overall duration of muting must be taken into account, if any.
5. All the safety photocells and
muting
sensors must be arranged so that
the previous material clears the last
muting
sensor before the new
material reaches the first sensors
Example of conveyor protection installation, which must allow a box to pass through
but not a person. The
SLC
S
is connected to the control panel, and
A1
,
A2
,
B1
and
B2
are sensors used to enable
muting
. The contacts for these sensors are controlled
on the transceiver unit.
Sensors
A1, A2,
B1 and B2
can be optical, mechanical or proximity sensors etc., with
closed contact in the presence of the object to be detected.
