Control signals
For the bypass function of the single beam safety light barrier, PLC control signals can be
used. For this purpose, inputs and outputs of the PLC are used as muting senders. The
functions muting start and muting stop are then induced by the PLC. The PLC is
programmed to react on the test request of the TMC 66. The test of the PLC inputs and
outputs is induced before every muting procedure while connecting the control signals.
INote!
The control signals control 1 and control 2 have to be generated by two different signal
sources if a PLC is used as muting sender. Control 1 can come from the PLC, whereas
control 2 will be deduced from a contactor which switches the conveyor belt on and off.
