Troubleshooting
The following information is used for rapid troubleshooting in the event of a malfunction.
9.1
What should 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 found that the error cannot be clearly
defined and remedied, your local Leuze office and or the
Leuze electronic
hotline can
assist.
9.2
Diagnostics
Operational malfunctions often have simple causes that you can remedy yourself. The
following tables will help you do this.
9.2.1
Transmitter diagnostics
9.2.2
Receiver diagnostics
The receiver distinguishes between error codes (E xx) and fault codes (F xx). Only error
messages (E) provide information about events or states that you can eliminate. If the
receiver shows a fault code (F), it must be replaced. Consequently, only error codes (E)
are shown in the table below:
