Muting Basics
It is necessary to suppress the function of the single beam safety light barrier for a certain
period, if material has to be transported from or into the hazardous area. This suppression
procedure is called muting.
The TMC 66 has two muting preparation signals Control 1 and Control 2, as well as two
muting signals Start 1 and Start 2 for the muting function.
Note!
The TMC 66 is equipped with a direction detection to avoid manipulation. The inputs Start 1
and Start 2 have to be activated in the correct order. During the muting procedure, both
signals have to be permanently present. An interruption causes immediate abortion of the
muting function (drop-off of safety relays).
