If the sensor doesn’t respond
Check the sensor response after each step and continue only if the sensor
fails to respond.
1 Check the connectors and ensure there is power to the sensor.
2 Replace the sensor.
If the sensor responds
1 Trigger the sensor again and check if the PLC responds (through 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.
4 Trigger the sensor again.
5 If the PLC still does not respond, replace the gap sensor connector
(with cable).
