Calibrate the height sensors
For calibrating the height sensors, TEBS E system training or a successfully com-
pleted E-Learning course is mandatory.
Only after obtaining the PIN 2 are you authorised to perform the calibration, see
chapter 11.2 ‘System training and PIN’, page
Prerequisites for a successful calibration
• The characteristic curve range is 966 - 1660 Timer Ticks (TT).
• Normal level I must be between 1139 - 1486 TT.
• The upper calibration level must be greater than the sum of normal level I
(Normal level) and 3x the tolerance value for the nominal level (can be set with
the TEBS E Diagnostic Software) + 5 mm.(e.g. arresting cables).
• Formula: Upper calibration level > normal level + 3x tolerance value of nominal
level + 5 mm
• The lower calibration level value must be less than the difference of the normal
level minus 2 times the nominal level tolerance.
Formula: Lower calibration level < normal level - 2x tolerance value of nominal
level
Restricting cables are attached around the axles so that the body cannot be lifted
too far, in order to limit the maximum height.
A characteristic curve error appears in the diagnostic memory in the event of an
implausible calibration.
– Move the vehicle into a horizontal position at the height of normal level before
starting the calibration.
3-point calibration
Application: for individual calibration of a vehicle.
This type of calibration corresponds to the standard ECAS systems.
– Press
the
Start calibration
button.
Adjust the vehicle to normal level I using the Lifting/Lowering buttons.
– Press
the
Save normal level
button.
An input field appears into which the distance between the load floor or the
top edge of the vehicle frame at normal level I relative to the road is entered
(in mm). Always measure the distance in the vicinity of the axle to be cali-
brated.
– Adjust the vehicle to the upper level using the Lifting/Lowering buttons.
– Press
the
Save upper level
button.
An input field appears into which the distance between the load floor or the
top edge of the vehicle frame at upper level relative to the road is entered (in
mm).
– Adjust the vehicle to the lower level using the Lifting/Lowering buttons.
– Press
the
Save lower level
button.
An input field appears into which the distance between the load floor or the
top edge of the vehicle frame at lower level relative to the road is entered (in
mm).
If the calibration was successful, a corresponding message appears.
