What If The Safety Light Curtain Does Not Work?
- Jul 09, 2018 -

The safety light curtain does not work, and there are many reasons for it. Let's see what it does. The safety light curtain has no output. Look at the indicator light of the sensor or the digital display shows what fault code is displayed. If the sensor always shows a red light or blinks continuously, it may be a sensor failure, or a transmitter and receiver pair. Not allowed, it will always display a red light. If there is a digital display on the sensor, the fault symptom code is generally displayed, and the fault can be judged according to the code display. There is also the possibility that the sensor indicator is normal, but the device is in an alarm state. It may be that the controller has a problem, and it needs to be removed and sent for maintenance.
