1. Ensure that the safety light curtain is correctly powered on.

2. Check and confirm that the serial cable used to connect the controller is a straight line, not a penetration line.

3. Check and confirm that the serial port connection cable is intact and the two ends are not loose or falling off.

If the safety light curtain still fails to operate normally after the above review and correction, please use a multimeter to measure whether the serial port of the connected control system hardware is damaged to confirm whether it should be returned to the safety light curtain manufacturer for inspection and repair. Of course, if you do not understand, you can communicate with safety light curtain manufacturers, and repair it simply according to the requirements of safety light curtain manufacturers, and return to the factory for maintenance.
