to avoid the possibility of accidental passing through the light curtain with Muting
active (Figure 12).

4 sensors
For correct positioning of sensors 1, 2, 3 and 4, i.e. those that manage enabling and disabling of the
Muting function, take into account the following:
Figure 13
SEQUENTIAL (Figure 8, Figure 13 Table 1):
 the distance between the first and the
last sensor must never exceed the length
of the pallet (in one of the phases of
the sequence, the 4 sensors must all
be intercepted simultaneously);
 the pallet must interrupt sensors S1 and
S2 (or S4 and S3 in the opposite
direction) before intercepting the light
curtain;
 make sure that the two beams are
intercepted by the material on the pallet
and not by the empty pallet
Figure 14
CONCURRENT (Figure 14):
 The Muting function is activated following
concurrent interruption (within max. 4
sec) of sensors S1 and S2 (or S4 and
S3 in the opposite direction).
 also in this operating mode, for correct
activation of the Muting function, for a
short period of time, all 4 sensors
must be intercepted simultaneously.
