Figure 6 shows the correct muting sequence and highlights how the
muting cycle differs according to whether 2 or 3 sensors are used.
Note:Note: The signals represent the voltage logical levels at the inputs of the control unit.
TS1S2TS1S2 is the time between detection of the material in transit by sensor 1 (or 2) and detection by
sensor 2 (or 1 ). If TS1S2 is less than 4 seconds, the AU S3M2 activates muting.
Tp = 300msTp = 300ms is the response time of the control unit on switching of the muting signals. Delay time
introduced by the unit to filter switching bounce-back.
T3 T3 is the moment of occupation of sensor 3. Interception may take place when the muting function is
active or after de-activation of this.
