3 Safety information
Observe all required regulations and instructions:
– Read this publication thoroughly.
Adhere to all instructions, information and safety information to prevent injury to
persons and damage to property.
WABCO will only guarantee the security, reliability and performance of their
products and systems if all information in this publication is adhered to.
– Make sure to follow the specifications and instructions of the vehicle manufac-
turer.
– Maintain all accident regulations of the business as well as regional and na-
tional regulations.
Make provisions for a safe work environment:
Only trained and qualified technicians are to perform any work on the vehicle.
– Use personal protective equipment if required (protective goggles, respiratory
protection, ear protectors, etc.).
Pedal actuations can lead to severe injuries if persons are in the vicinity of the ve-
hicle. Make sure that pedals cannot be actuated as follows:
– Switch the transmission to ‘neutral’ and actuate the park brake.
– Secure the vehicle against rolling with chocks.
– Fasten a visible note to the steering wheel indicating the work is being per-
formed on the vehicle and that the pedals are not to be actuated.
Avoid electrostatic charge and uncontrolled discharging (ESD):
Note during construction and building the vehicle:
– Prevent potential differences between components (e. g. axles) and the vehicle
frame (Chassis).
Make sure that the resistance between metallic parts of the components to the
vehicle frame is lower than 10 Ohm.
Connect moving or insulated vehicle parts such as axles electrically conductive
with the frame.
– Prevent potential differences between the towing vehicle and the trailer.
Make sure that an electrically conductive connection is made between metal
parts in the towing vehicle and the coupled trailer via the coupling (king pin, fifth
wheel, claws with pins), even without a cable being connected.
– Use electrically conductive bolted connections when fastening the ECUs to the
vehicle frame.
– Run the cable in metallic casing if at all possible (e. g. inside the U-beam) or
behind metallic and grounded protective plating, to minimise the influence of
electro-magnetic fields.
– Avoid the use of plastic materials if they can cause electrostatic charging.
– For electrostatic painting, connect the ground line of the ISO 7638 plug connec-
tion (pin 4) to the paint ground (vehicle chassis).
Note during repair and welding work on the vehicle:
– Disconnect the battery - if installed in the vehicle.
– Disconnect cable connections to devices and components and protect the plug-
ins and connections from contamination and humidity.
– Always connect the grounding electrode directly with the metal next to the weld-
ing position when welding, to prevent magnetic fields and current flow via the
cable or components.
– Make sure that current is well conducted by removing paint or rust.
– Prevent heat influences on devices and cabling when welding.

Special note when using prefabricated TEBS support modules for installation
in the vehicle:
By optimising production processes at trailer manufacturers, many prefabricated
TEBS support modules are installed in the trailer. The TEBS E Modulators as well
as many different valves are fastened to these cross-member supports. These
support modules are often painted so that when installing in the vehicles, the elec-
trical contact between the vehicle frame and the support module has to be properly
connected again.
Ensuring the electrical contact between the support module and the vehicle frame:
– Fasten the support module with electrically conductive bolted fasteners using
self-tapping screws with a conducting surface to the vehicle frame.
The resistance of the support module and the frame must be < 10 Ohm.

Braking system
The trailer vehicle is connected to the towing vehicle via two hose couplings for
supply pressure (3) and control pressure (2). The park release emergency valve
(PREV, 20) is used to conduct the control pressure to the TEBS E modulator (19).
The PREV is equipped with a red actuating button (13) for actuating the parking
brake, as well as a further black actuating button (14) for releasing the brake which
is automatically actuated when the trailer vehicle is unhitched. The compressed air

4 TEBS E
Introduction

from the reservoir flows to the Pneumatic Extension Module (PEM, 5) via a check
valve integrated in the PREV.
The PEM includes the following functions:
• a charging valve for securing pressure in the air braking system apart from the
air suspension,
• an overload protection valve to protect the wheel brakes from overloading –
when service and parking brake are actuated simultaneously,
• a pressure distribution for the supply ‘air suspension’ and supply ‘service brake’.
The TEBS E Modulator controls the service brake components (8) for the Tristop®
cylinders (9). At least two rotational-speed sensors (18) are connected for sensing
the wheel speeds. A pressure test connection is also provided on the PEM for
measuring the current braking pressure. The PEM charges the service brake sys-
tem reservoir (10) with the supply pressure from the PREV.
The same line is used to supply the TEBS E Modulator with supply pressure from
the reservoir. The reservoir for the air suspension system (11) is charged via the
charging valve integrated in the PEM. The charging valve has the task to ensure
that primary pressure is maintained in the ‘Brake’ reservoir and thus the ability of
the towing vehicle to brake, in the event of a pressure drop in the air suspension
system. In order to protect the wheel brakes from overloading from the additional
brake force (diaphragm part and spring chamber of the Tristop® cylinder actuated
simultaneously), an overload protection valve (7) is integrated in the PEM. The
pressure is distributed to the Tristop® cylinders (9) by the PEM.
The parking brake is actuated by pressing the red button on PREV (13). This ex-
hausts the parking brake component of the Tristop® cylinder so that the integrated
spring can actuate the wheel brake. If the service brake is also used while the
parking brake is actuated, the braking pressure flows into the parking brake com-
ponent of the Tristop® cylinders via the overload protection valve, thereby relieving
the force in the parking brake component in proportion to the braking force built up
in the service brake component and so ensuring that there is no addition of force.
Conventional air suspension system
The conventional air suspension system consists of a levelling valve (17) and a lift-
ing/lowering valve, e.g. TASC (12) see chapter 6.4 ‘Speed switch (ISS 1 and ISS 2)
and RTR’, page 75. Both valves are supplied with supply pressure from the PEM.
The levelling valve adjusts to the normal level (ride height) of the trailer vehicle by
adjusting the amount of air in the support bellows (15). The lifting/lowering valve
can be used to change the level of the trailer vehicle manually, e. g. for loading or
unloading. In addition, a lifting axle valve (16), which is modulated by the TEBS E
Modulator relative to load, may also be installed. The lifting axle valve is also sup-
plied with supply pressure from the PEM.
