After switching on the safety relay, display elements (LEDs, see chapter 3.2 Display elements ) assist in
checking the proper function and troubleshooting.
In case of failure, you can determine the fault from the LED displays. With the error message you can
determine the cause of the fault and initiate measures to rectifying it.
Switch off the machine and leave it switched off.
Analyze and eliminate the cause of the fault (see chapter 11.2 Operating displays of the LEDs ).
If you are unable to rectify the fault, contact the Leuze electronic branch responsible for you or call the
Leuze electronic Hotline.
