Troubleshooting

11.1 What to do in case of failure?

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 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.

11.2 Operating indicators of the LEDs



If it was possible to rectify a detected error, perform an "MSI restart" (24 V on terminal 21) or briefly dis

connect the MSI-TRxB from the voltage supply.

NOTE

If the safety relay indicates a fault, it may be defective.



Switch off the machine and leave it switched off.



Analyze and eliminate the cause of the fault (see chapter 11.2 "Operating indicators of the

LEDs").

If you are unable to rectify the fault, contact the Leuze branch responsible for you or call the

Leuze hotline.
