EBS22
: No message with the total load from the sum of the single axles is trans-
mitted to the towing vehicle.
RGE22
: The individual loads of the axles are not transmitted to the towing vehicle.
Transmission of both messages is the default setting.
In some towing vehicles faults can occur if the transmitted data appears implausi-
ble. One of the messages should be deactivated where this is the case.
Calibration of the axle load output
In order to attain higher precision for the axle load output, the output can be cali-
brated via the SmartBoard. The calibrated value is transferred to the towing vehicle
via the ISO 7638 port and also displayed on the SmartBoard.
For calibration, an additional characteristic curve based on the weights of an
unladen, partially laden and fully laden vehicle. A 3-point characteristic curve is
stored in TEBS E. A detailed description can be found in the ‘SmartBoard – Sys-
tem description’ see chapter 4 ‘Introduction’, page
12
=> ‘More information’ section.
The calibration procedure has been improved so that a message is not
stored in the diagnostic memory in the event of a failed calibration.
Optionally 1, 2 or 3 points can be calibrated. Each value can be
changed separately, significantly improving the accuracy of the indica-
tion.
Once a value has been calibrated it is immediately integrated in the characteristic
curve for the axle load output. The calibrated minimum/maximum values may only
deviate up to max 20 % from the characteristic curve defined by LSV.
The calibrated values for the unladen, partially laden and laden vehicle must not be
below a defined minimum distance from one another (minimum of 10 %).
The bellows pressure changes slightly when the vehicle height is changed. Prior to
calibration, the vehicle height should therefore be adjusted to the height subse-
quently relevant for the axle load output. Generally this will be the normal level.
Because the air bellows' properties change over the service life, a recalibration
may be required.
Please note that a calibration already started via the SmartBoard must also be con-
cluded, otherwise a fault message is issued.
Fault indicator / warning lamp: Optionally it is also possible to program the unit in
the SmartBoard so that the fault indicator / warning lamp (red) flashes on the
SmartBoard when the axle load reaches 90 % and 100 % to indicate the danger of
overloading, when loading particulate material for example.
