Keyence light curtain error 5 0

Follow

Hi,

Can you give us the part number of the light curtain?

It's GL-R52H-R and GL-R52H-T

Just figured it out. I had the sync wires murretted together just to keep them out of the way.

Error code 50 on a Keyence light curtain typically indicates a communication error between the emitter and receiver units. This can be caused by a number of issues, including faulty wiring, incorrect power supply voltage, or a problem with the light curtain itself.

Here are some troubleshooting steps you can try:

Check the emitter and receiver units: Make sure that the emitter and receiver units are properly aligned and that there are no obstructions blocking the light curtain.

Reset the light curtain: Try resetting the light curtain by turning off the power and then turning it back on.

Check the wiring: Make sure all wiring connections are secure and free from damage. Check the wiring diagram in the manual to ensure that the wiring is correct.

Check the power supply voltage: Verify that the power supply voltage is within the specifications listed in the manual.

It's also worth noting that the error code may be specific to your particular model of light curtain. If you're still having trouble after trying the above steps, it may be helpful to provide Keyence with more specific information about the model number and other details of your light curtain.
