Installation
Information on installation, see chapter 8.5 ‘Installation height sensor’, page 150.
Parameter s
etting
Definition of a vehicle with mechanical suspension is carried out via tab 2, Vehicle.
The GIO port for the height sensor is specified via tab 11, Connectors.
Calibration
Information on calibrating, see chapter 9.4.1 ‘Calibration for vehicles with mechani-
cal suspension’, page 170.
5.9.3 Pressure control
The pressu
re control circuits take the set point pressures specified by the LSV
function and convert them into cylinder pressures.
The TEBS E Modulator takes the actual value pressures measured at the output of
the relay valves and compares them with the nominal pressure specification.
If there is a discrepancy, this is compensated for by actuating the inlet or exhaust
solenoids of the modulator or the 3rd modulator.
If the measured supply pressure exceeds 10 bar, pressure control and ABS control
is deactivated and braking is done via the backup alone.
In accordance with the EC- and ECE guidelines, a maximum of 8.5 bar supply
pressure is permitted in the trailer.
Pneumatic predominance and Predominance via CAN
For fine-tuning and harmonizing of brake pad wear, a predominance can be de-
fined.
The values for the pneumatic predominance and CAN predominance can vary.
Parameter setting
A predominance is entered via tab 3, Brake data.
