MUTING
INSTRUCTION MANUAL 51
After this time if the user wants to enter in Muting has to deactivate the Muting input
and start the sequence from the beginning.
Figure 20 - T Muting timings
The sensors named A1/A2 are connected to the same Muting input (MUTING1) and the
sensors named B1/B2 are connected to MUTING2.
The sensors that end with “1” are on the same side of the light curtain and are on the
opposite side of the sensors that end with “2”.
“D” is the distance at which the sensors A1/A2 or B1/B2 have to be mounted; it depends
on the package length (L):
D < L
“d1” is the maximum distance between the Muting sensors; it depends on the package
speed (V):
d1max[cm] = V[m/s] * T12[s] * 100,
“d2” is the maximum distance for the Muting request to be accepted; it depends on the
package speed (V):
d2max[cm] = V[m/s] * T12[s] * 100,
where “T12” is the activation delay between MUTING1 and MUTING2 that is selectable
by the user by means of ACM.
