Diagnostics and troubleshooting
11.1
What to do in case of failure?
After switching on the muting controller, the display elements (see chapter 3.2 "Display elements") assist in
checking the correct functionality and in fault-finding.
In case of failure, you can read a message from the 7-segment display. With the error message you can
determine 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!
Ä
Switch off the machine 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 12 "Service and support").
With the
Sensor Studio
diagnostics software, you can create a service file that you can send to Leuze elec-
tronic customer service in the event of service requests (Diagnostics software Sensor Studio). The service
file contains all available information on the muting controller, as well as configuration and settings.
