12 Diagnostics and troubleshooting
12.1 What to do in case of failure?
After switching the safety sensor on, the display elements assist in checking the correct functionality and
in faultfinding (see chapter 3.3 "Display elements").
In case of failure, you can determine the fault from the LED displays and read a message from the display.
With the error message you can determine the cause of the error and initiate measures to rectify it.
12.2 Diagnostics displays
The diagnostics displays consist of one letter plus four numbers, divided into classes consisting of letters
and the first number.
Diagnostics classes:
• I (Information)
• No OSSD switch-off
• Unhindered operation possible
• U (Usage)
Application error
• E (External)
External fault
• F (Failure)
Internal device error
• OSSD switch-off
• Self test unsuccessful
• Hardware error
• P (Parameter)
Inconsistency in configuration

NOTICE
If the safety sensor responds with an error display, you will often be able to eliminate the cause yourself!
Switch off the machine and leave it switched off.
Analyze the cause of the fault using the diagnostics displays and rectify the fault.
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").
