Sequence of a muting cycle
If the muting sensors MS1 and MS2 are activated within a 3-second period, the muting cycle is initiated.
The muting lamp is switched on and interruption of the safety light barrier does not cause the device to
switch off. If three of the four muting sensors are inactive, the muting cycle is terminated after a delay
period of 0.25 seconds.
