Error diagnostics

7 Error diagnostics
The following information is used for rapid troubleshooting in case of failure.
7.1

What to do in case of failure?

If the AOPD shows an error on the display, the machine must be stopped immediately and checked by
competent personnel. If it is determined that the error cannot be clearly defined and remedied, your local
Leuze office and/or the Leuze hotline can assist.
7.2

Diagnosis

Operating faults often have simple causes that you can remedy yourself. The following tables provide
detailed assistance.
7.2.1

7.2.2

Receiver diagnosis

The receiver distinguishes between error codes (E xx) and fault codes (F xx). Only error codes (E) provide
information about events or states that you can remidy. If the receiver shows a fault code (F), it must be
replaced. Consequently, only error codes (E) are shown below:
Code
