7.7.3  Typical muting application and sensor connection 

 

 

Fig. 40 – Typical muting application 

 

The diagram above shows a typical muting application: the protection device installed on the 
conveyor must allow the package to pass through but not the operator.  The light curtain 
temporarily suspends its safety function when the sensors A11, A21, A12, A22 are activated 
in the correct sequence. 
These may be optical or mechanical sensors that switch 24 V when the object is detected. 

 

7.7.4  Muting direction 

The light curtain can be used for bidirectional muting (T-type, four sensors) as well as one-
directional muting (L-type, two sensors). 

  T-muting is used when objects can move through the light curtain in both directions. 

  L-muting is used when objects move only in one direction. 

 
In BCM mode the maximum activation delay between MUTING1 and MUTING2 (T12max) is 
4 seconds 
 

T-Muting 

With T-type operation, the device switches to the muting function if the signal from the 
MUTING2 input switches within a fixed T12max, after the MUTING1 signal has switched (or 
vice versa). The muting function ends as soon as the signal at MUTING1 or MUTING2 goes 
low.  Once this time has elapsed, if users wish to switch to muting status they will need to 
deactivate the muting input and start the sequence again.
