The lift axle traction help (or forced lifting) is being activated :
1) either through an impulse button connected to the power supply (+24 V) or minus (0 V) and on a
GIO of the modulator (with cable) and if the parameters have been set accordingly. The impulse
on the button needs to be between 0,1 and 5 seconds.
2) or by pushing 3 times the brake pedal if the parameters have been set accordingly on the GIO of
the modulator (without cable).
3) or through the SmartBoard if the parameters have been set accordingly.
In order to disconnect the lift axle traction help :
1) either when the impulse on the button is more than 5 seconds (with cable).
2) or by pushing again 3 times the brake pedal (without cable).
3) or through the SmartBoard.
Wear indicator (optional)
Up to 6 indicators for monitoring wear on the brake pads can be connected to the electronic system.
The wear indicators (a wire integrated into the brake pad) measure the wear on both brake pads. All
indicators are connected in series and connected to the wear input in a voltage distributor. The driver is
alerted via the ABS warning light shortly before and when the limit of wear has been reached.
Warning light
Warning phase 1
When the wire in the indicator has been worn down
during braking (> 3 braking operations), short-circuiting
towards earth (earth connection between brake and
chassis is essential) occurs and warning phase 1 is
activated. During the first warning phase, the ABS
warning light will flash 4x (1 cycle) once the ignition has
been switched on.
Warning phase 2
When the wire in the indicator has been worn through for
4 minutes, a voltage of 4.5 volts is measured in the wear
input and warning phase 2 is activated. During the
second warning phase the ABS warning light flashes 4 x
4 cycles (total of 16 times) once the ignition has been
switched on.
The warning is interrupted when the trailer exceeds a speed of 7 km/hour. In case of system faults, the
ABS warning light is permanently activated.
The corresponding information is simultaneously transmitted to the lorry/trailer interface and can be
displayed on the display.
The system automatically detects when new wear indicators have been installed after the brake pads
have been replaced. All warning lights will be de-activated after approx. 2 minutes (switch on ignition for
a minimum of 2 minutes). The warning light will only go out when the ignition is switched on again.
The last five replacements of the brake pads (position of kilometre indicator and operational hours
when the second warning phase and replacement of brake pads have taken place) are stored in the
ECU and can be read using the PC diagnostics.

The connecting points on the trailer are located at the front. The command line is colour coded yellow
and the supply line is colour coded red.
Figure 3.3.a. – Connection braking system
 When uncoupling the connecting hoses, the brakes are automatically
activated.

Once the air pipes have been disconnected, the connecting points should be
protected against soiling by water or dust by placing the lids of the
connections over the apertures.
 The parking brake is NOT automatically set once the command and supply air
pipes have been disconnected.
 Repairs to the brake system may only be carried out by qualified engineers.
 Any components in the brake system which need replacing should always be
replaced by original components.
Trailers equipped with the EBS-E brake system may only be coupled to lorries
with either:
 an ISO7638-1996 electrical connection (7-pin, 24V, CAN-databus),
 an ISO7638-1985 electrical connection (5-pin, 24V, no CAN-databus).
