10 Troubleshooting
The following information is used for rapid troubleshooting in the event of a malfunction.
10.1 What do I do if an error occurs?
If the AOPD shows an error on the display, the machine must be stopped immediately and
checked by an experienced technician. If it is determined that the error cannot be clearly
defined and remedied, your local Leuze office and or the Leuze electronic hotline can
assist.
10.2 Diagnostics
Operational malfunctions often have simple causes that you can remedy yourself. The
following tables will help you do this.
10.2.1 SD4T Transmitter diagnostic
