Troubleshooting; What To Do In Case Of Failure; Operating Indicators Of The Leds - Wieland SLC Series Operating Instructions Manual

11 Troubleshooting

11.1 What to do in case of failure?

After switching the safety sensor on, the display elements (see chapter 3.4 "Display elements")
assist in checking the correct functionality and in faultfinding.
In case of failure, you can determine the fault from the LED displays or 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 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 and eliminate the cause of the fault using the following table.
Ä If you are unable to rectify the fault, contact the Wieland Electric branch responsible for
you or call the Wieland Electric customer service (see chapter 13 "Service and support").
