Inputs and Testing Continued...
Testing inputs is very simple, like the flick of a light switch. To test proximity sensors pass
a metal object across the face of any sensor. Lights on both the proximity sensor and
PLC Input should light up. To test inputs operated by switches, depress the lever on the
switch and the appropriate input should light up.
The following wiring drawings will show the simplest way a switch and proximity sensor
connect to the PLC.
Below is an example of a typical input circuit using a switch. One side of the switch
goes to the PLC Input and the other side of the switch goes to Negative Voltage. The
PLC Input Common is supplied with Positive Voltage. The circuit is shown in the open
position so there will be no input light on the PLC. The batteries will supply the 24 Volts.
All of the machine switches are wired like this. The only difference is that the wires will
pass though plugs and junction blocks.
