Smart Tachograph EFAS-4.10/4.11
6.2.3
Motion sensor
The motion sensor must conform to EU regulations and must be a type approved for use with the EFAS device. Install the motion
sensor in accordance with the manufacturer’s instructions. After the motion sensor has been installed, it can be connected to
the sensor cable. The other end of the motion sensor cable is connected to socket B on the back of the recording device. If you
are installing cabling for the tachograph in a vehicle for the first time, please refer Table 6 to Table 9 for the pin assignments of
the plug.
If you are using existing cabling for the installation, checks should be made to exclude any branch connections. If a full sight
check is not possible, a reference cable should be used for testing between the sensor and the EFAS tachograph.
During activation the motion sensor is paired with the tachograph. They then form a single unit that is referred to as recording
device. In this process, please follow the vendor’s instructions for the motion sensor used and observe the vehicle manufactur-
er’s installation instructions.
6.2.4
Mounting on the vehicle
Attach the mounting on the back of the device (M6 threaded bolts, rubber pads, etc.) to a suitable location in your vehicle. This
may only be possible after it has been inserted into the installation bracket.
Insert the tachograph into the intended bay until you hear the clips click into place.
6.2.5
Conditions for switching-on and operating states
The EFAS tachograph is activated by the following signals (conditions for switching on):
y
Connection to the power supply
y
Switch on the ignition
y
Card insertion
y
Key-press
y
Motion sensor signals
y
Optionally by an external switch-on signal (from devices connected to the CAN bus C)
y
Optionally at the end of a 45-minute interruption in travel time
When the ignition is turned on, the EFAS tachograph is in normal operating mode. If the ignition is turned off, only restricted
operation is possible where it is not possible to eject a card from the slot and printing is not available.
If there is no condition for switching on present, the EFAS device enters standby mode after a certain shutdown time. In standby
mode, less power is consumed and the display is switched off. The default for the shutdown time is approve. 2 minutes. The
EFAS
Service Tool
can be used to set a longer or shorter shutdown time. (In the EFAS Service Tool referred to as “EFAS Follow-up Time”)
The minimum shutdown time is 60 seconds. If there is no condition for switching on present, the display lighting is switched off
after approx. 15 seconds. Depending on the programmed shutdown time the EFAS device will switch into standby mode at the
end of the specified time.
6.2.6
Changing the internal buffer battery
The internal buffer battery must be replaced with each regular inspection or recalibration, if the date of the previous inspection
was more than 12 months ago. The date of the previous inspection is given on the installation plaque or on the printout of the
“Technical Data”.
6.2.6.1
Removing the internal buffer battery
Before removal of the battery the tachograph must be put to CALIBRATION mode to avoid damages to the tachograph.
For this the insertion of the workshop smart-card and the PIN entry is required. By the operating mode CALIBRATION error
entries can be avoided in the device, which can result from the separation of the supply voltage of the vehicle.
If the tachograph is installed in the vehicle, then install the tachograph with the help of the unlocking clamp. Check if the device
is fastened at the rear and loosen the fastener if required.
The tachograph can now be separated from the connecting cables and connected to an external power supply (12 V or 24 V).
