Troubleshooting
12.1
What to do in case of failure?
After switching on the light curtain, display elements (see chapter 3.4) assist in checking the proper func-
tion and troubleshooting.
In case of error, you can determine the error from the LED displays. With the error message you can deter-
mine the cause of the error and initiate measures to rectify it.
NOTICE
If the light curtain responds with an error display, you will often be able to eliminate the cause yourself!
Switch off the system and leave it switched off.
Analyze and eliminate the cause of the fault using the following table.
If you are unable to rectify the fault, contact the Leuze electronic branch responsible for you or call the
Leuze electronic customer service (see chapter 14 "Service and support").
