Manual motion sensor pairing

The motion sensor pairing process is launched automatically when the device is activated. Start the pairing manually if auto
pairing was unsuccessful, e.g. if the motion sensor was not connected during activation, or if you need to repeat the pairing of
EFAS with the motion sensor.
Motion sensor pairing is possible only in CALIBRATION mode. The tachograph switches into CALIBRATION mode after plugging
in the workshop smart-card and enter the corresponding PIN (see section 6.4, step 2).
The pairing process is launched using an appropriate calibration device or with the EFAS Service Tool via the EFAS menu. The
pairing process can take up to three minutes.
When using a calibration device, it generally displays information on the progress and success of the motion sensor pairing
process.
If you use the EFAS Service Tool you will receive all necessary information on the progress and success of the pairing process as
well as key data of the paired motion sensor on the computer running the EFAS Service Tool.
Proceed as follows to start the pairing from the EFAS menu.
Select: OK g Installation g  Sensor connection g Sensor pairing Start YES/NO
Use the cursor key  or  to choose YES and press OK. The process of pairing the sensor with EFAS commences and the
following is displayed:
Figure 30 — Sensor pairing commences
The process of the pairing is displayed at the bar chart and the percentage.
Figure 31 — Successful end of the sensor pairing
After the pairing is complete EFAS switches back to the item " Sensor connection" and then to the default display. If
the pairing is unsuccessful, an error message is displayed.

Note
Sensors according to Annex 1B could usually be coupled several times, whereby one and the same sensor can
be coupled successively with different tachographs. An Annex 1C sensor can always be recoupled with the
same tachograph unless there is a defect. If the sensor coupling fails multiple times, consider replacing the
sensor.
There is also the possibility that Annex 1C sensors will not activate immediately after a power interruption, but
will only function properly again after a certain period of time.
If the workshop card is ejected on pairing errors, the following display occurs:
Figure 33 — Display of service ID on workshop card ejection
If a service ID is displayed the card ejection may be aborted by pressing the back key 9. The workshop technician should correct
the problem before the workshop card is removed in order to avoid the entry of an event or fault. As a reminder, the following
screen is displayed:
