11 DETECTORS' ERRORS
11.1 Data Reception/Transmission Error between Detectors and Cabin
During data transmission/reception between detectors and cabin, the following screen may be
displayed:
Figure 71
This means that there is a transmission/reception failure due to one or several of the following
problems:
•
Detectors infrared transceivers are not working
•
There is a failure or a radio interference inside the transmission system,
•
There is a hinder (ex. vehicle door open) between front and rear detectors.
Rear detectors do not directly communicate with cabin: their data are transmitted/received
passing through front detectors so, if a front detector is not working properly, data could not be
transmitted to the corresponding rear detector, even if this latter is working.
If the cause of failure is eliminated (ex. vehicle door is closed) error page will immediately
disappear, and the measurement page will be displayed again. If the problem continues, check
system hardware by switching machine off. Of course, it is not recommended to abruptly power
cabin off; follow the correct switching off procedure:
•
Press “Esc” on keyboard to go back to the introduction page (chap.8 on page19).
•
Switch machine off following the correct procedure (see par.4.2 on page 13).
