6.2.1. ERROR MESSAGES OF THE DISPENSER
In every defect of the dispenser equipped with the PDEX5, PDEX, TBELTM or TBELTX counter, delivery is
interrupted and the display shows an error message ("E" + error code). Depending on the message type, either
the whole dispenser is blocked (fatal error), or only the part where the fault appeared is blocked.
Important error messages are saved in the counter memory, where they can be shown using parameter Error
message code history and Error message code statistics.
