SLG 415 L – DESIGN OF THE MUTING FUNCTION WITH 2 PRE-ASSEMBLED MUTING SENSORS
Integrated Muting sensors – for one-way openings with pallet exit
In this model, the sensors 1 and 2 are on the same side of the
vertical light grid and are placed in front of the guarded opening.
This model is one-way and is useful for protecting pallet exit
openings.
The Muting function is activated following concurrent interruption
(within max. 4 sec) of sensors S1 and S2. The Muting function
remains active as long as both sensors remain occupied.
When the first of the 2 sensors is cleared, the material has four
seconds to leave the guarded area delimited by the light grid. The
Muting condition will be disabled as soon as the protected area is
cleared.
After 4 seconds, if the light grid is still occupied, the OSSD outputs
are disabled, interrupting the function of the machine.
For this model, the maximum duration of the Muting condition
(timeout) can be set to 30 seconds or 90 minutes.
To guarantee the safety operation of the SLG 415 L
systems, the horizontal muting sensor must be
mounted INSIDE the dangerous area.
When using a SLG 415 L, the minimum distance
between two consecutive pallet must be 40cm.

SLG 415 T – DESIGN OF THE MUTING FUNCTION WITH PRE-ASSEMBLED MUTING SENSORS
Integrated Muting Sensors – for two-way openings with pallet entrance/exit
In this model, the Muting sensors are on both sides of the
vertical light grid.
This model is therefore two-way and is useful for
protecting pallet entrance/exit openings.
The point of intersection of the two muting
sensors must be inside the dangerous area
in order to avoid accidental actuation of the
Muting function.
The Muting function is activated following concurrent
interruption (within max. 4 sec) of sensors S1 and S2.
The Muting function remains active as long as both
sensors remain occupied.
When the first of the two sensors is cleared, the Muting
function is disabled.
Also for this model, the maximum duration of the
Muting condition (timeout) can be set to 30 seconds
or 90 minutes.
