Wiring of single-beam protective photoelectric sensors in series
Several photoelectric sensor pairs can be connected to the TNT 35/7-24 in series with
multi-axle arrangements on a machine or system. The adjacent picture shows a three-axle
photoelectric sensor arrangement. It is possible to operate up to
three
photoelectric sensor
pairs on one TNT 35/7-24V.
Function characteristics:
The TNT 35/7-24V (terminal 14) activates the first photoelectric sensor transmitter. The
receiver is activated via the first optical path and, by using its output, activates the second
photoelectric sensor transmitter. The supply has to provided on each photoelectric
transmitter and receiver. The feedback to the TNT 35/7-24V (terminal 15) is done by the
last photoelectric sensor receiver within the series connection.
Any time the light axis is interrupted, a message is issued to the TNT 35/7-24V through the
series connection.
The series connection tests every transmitter and receiver for function capability while
performing the testing procedure.
