Muting is the brief interrruption of a safety light barrier and is used wherever this is rquired by the the working cycle. For doing so, the Muting channels 1A, 2A and 1B and 2B must be under voltage. Muting is permitted only if the nature of the work cycle excludes any access into the hazardous area, or during non-hazardous machine movements. This is the case whenever, for instance, material is conveyed through the protctive field in a way
that there is no space for entering the area between material and safety light barrier, or if there is no hazardous movement. Application fields are e.g. safeguarding of pallettizers, narrow-aisle storage facilities, fork lift access areas, manufacturing cells, bending presses, rubber presses, presses with automatic material feeders, etc ...
