Wiring of Single Beam Safety Light Barrier in Series Connection

Several photo electric sensor pairs can be wired in series on the TMC 66 if multi-axis 
safeguarding needs to be installed on a machine or system. The figure below illustrates a 
three-axis photo electric sensor installation. It is possible to operate up to six photo electric 
sensor pairs on one TMC 66.

Function characteristics

The TMC 66 (terminal 1) activates the first photo electric sensor transmitter. The receiver is 
activated via the first optical path and, by using its output activates the second photo 
electric sensor transmitter. The supply has to provided on each photo electric transmitter 
and receiver. The feed-back to the TMC 66 (terminal 2) is done by the last photo electric 
sensor receiver within the series connection.

Any time the light axis is interrupted, a message is issued to the TMC 66 through the series 
connection.
The series connection tests every transmitter and receiver for function capability while 
performing the testing procedure.
