14.5 Permissible ABS configurations

ABS configurations for semitrailers, central axle trailers and drawbar trailers

Lifting axles

2S/2M system: Lifting axles are not allowed to have sensors fitted!

All other systems: Lifting axles can be fitted with ABS sensors e, f.

Steering axles

Constrained steering axles can be treated like rigid axles. WABCO prescribes EBS configurations 4S/3M,
4S/2M+1M or 2S/2M+SLV for vehicles with self-steering axles.

If 2S/2M or 4S/2M EBS systems are to be used in vehicles with self-steering axles, tests during the type test must
establish that there are no abnormal axle vibrations or course deviations. It is not possible to investigate all axles
on the market to check how they respond when ABS is triggered.

14.7 Cable overview

In some cases the cables look very similar (e.g. a 4-pin GIO connector and the 4-pin DIN bayonet).
However, this wide range of different cables is necessary because the components to be connected have
completely different pin assignments and the cables must not be interchanged even if they look alike.
A precise identification is necessary to rule out malfunctions and damage to components.

The connectors are coloured on the modulator end to facilitate identification.

System plate
After the trailer EBS system has been installed, the PC diagnostic program can be used for making an EBS
system plate displaying the setup data. This EBS system plate must be affixed in a clearly visible place on the
vehicle (e.g. in the area where the LSV plate is located in conventional brake systems). The blank foil for this type
plate can be obtained from WABCO, order number 899 200 922 4. The data must be printed out using a laser
printer.
