13 Diagnosis and troubleshooting
13.1 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 3.4 "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.
PROFIsafe alarm messages
The safety sensor can make alarms available for diagnostic purposes.
• If the safety sensor detects an error, it passes this on to the PROFIsafe control as an alarm.
• Both PROFINET-specific as well as device-specific alarms are realized in the safety sensor. Each
alarm can be selected and deselected individually.
• Alarm-specific help texts can be displayed on the PROFIsafe control or read out by the PROFIsafe con-
trol.
NOTICE
For safety sensors with PROFIsafe interface, the alarm messages, with the exception of the
PROFIsafe-specific alarms, are activated by default.
Ä If necessary, you can activate the alarms individually via the SensorStudio configuration
software.
NOTICE
If the safety sensor 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.
Ä Analyze the cause of the fault using the diagnostics displays and rectify the fault.
Ä If you are unable to rectify the fault, contact the Leuze branch responsible for you or call the
Leuze customer service (see chapter 15 "Service and support").
