FUNCTIONS

T muting
In T type operations the device enters muting function if the input MUTING2 goes high within
a fixed T12max after the rise of MUTING1 (or viceversa). The muting function ends as soon
as the signal on MUTING1 or MUTING2 goes low. The maximum activation delay between
MUTING1 and MUTING2 (or viceversa) can be set by the user from a minimum of 1 sec to a
maximum of 16 sec (T12max). After this time if the user wants to enter in muting has to
deactivate the muting input and start the sequence from the beginning.
Fig. 41 – 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):
d1 max [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):
d2 max [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.
