11 MEASURING HEADS ERRORS
11.1 Data receiving-transmission error between measuring heads and
console
During the data transmission/receiving between measuring heads and the console, the following
display page could appear
:
Figure 47
This means that there is a transmission/receiving fault due to one or more of the following
reasons:
There is an interruption of the cables and/or in the connectors on the connection between
front sensors and console.
There is an obstacle (e.g. door of vehicle open) between front/rear sensors.
The rear measuring heads fail to communicate directly with the console: their data are
transmitted/received passing through the front measuring heads. So, if a front sensor is defective,
it cannot transmit/receive data from the rear sensor, even though it is working properly.
If the cause of the error is removed (e.g. the vehicle door is closed) the error display page
immediately disappears and the measuring page again appears on the screen. If the error persists
it will be necessary to check the hardware of the system, after switching off the apparatus. Of
course it is never a good thing to suddenly cut the power supply to the console. The correct
switch-off procedure should always be followed:
Press the key “Esc” on the keyboard to return to the presentation page (chap. 8 page 21).
Proceed to switch off the equipment as usual (see para. 4.2 page 15).
11.2 Horizonatal plane angle measuring error
