Troubleshooting
If the sensor responds
1 Trigger the sensor again and check if the PLC responds (check the PLC
I/O indicator).
If the PLC responds, it was likely an intermittent failure and no further
action is needed.
2 If the PLC does not respond, perform a continuity check on the PLC’s
connector signal terminals.
3 If the continuity check fails, check the cables and connectors.
Troubleshooting PHS-12 to PHS-14, PHS-24 to PHS-26
