  • Page 11 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.

  • Page 12: Introduction

    Besides controlling wheel brakes, the Trailer EBS E Premium variant has a number of functions that can be created specific to the respective vehicle. Besides the solu- tions ‘prepared’ by WABCO, such as the control of air suspension systems or the dynamic wheelbase control, the methods for implementing customisable third-party controllers from the vehicle manufacturer is also explained in this chapter.

    Any events that occur during operation are stored in the Trailer EBS E and can be read out in the workshop using the TEBS E Diagnostic Software. The fault indicator / warning lamp must be monitored by the driver.
  • Page 36 Loss of tire pressure (IVTM) Warning signal with ignition on without detecting motion TEBS E switches the warning lamp / warning indicator on 30 minutes after the igni- tion has been turned on if no speed is detected via the wheel sensors. This func- tion results in incorrect messages when on a trailer with many axles and several TEBS E all axles of one TEBS E are lifted.

    TEBS E WARNING Risk of accidents caused by low supply pressure (< 4.5 bar) The vehicle can no longer be braked by means of the service brake. If the pres- sure at the coupling head is below 2.5 bar, the vehicle is automatically braked by the spring chambers.

  • Page 38: Brake Functions

    The braking request issued by the driver is referred to as the nominal value. If the trailer is towed by an EBS towing vehicle with a 7-pin (ABS) plug connection according to ISO 7638, the TEBS E gets the nominal value from the EBS vehicle via the trailer interface (CAN).

  • Page 50: Ecu-Internal Functions

    If a SmartBoard is installed, the distance travelled is also recorded here - inde- pendently of the TEBS E. This odometer keeps working even when the TEBS E is not supplied with voltage. Since the odometer in TEBS E counts the average values of all wheels, whereby the odometer in the SmartBoard counts distance on wheel sensor c, different tire circumferences (tire wear) can cause the odometer to vary.

  • Page 51: Service Signal

    If the vehicle reaches the next defined service interval (e.g. 200,000 km), the ser- vice signal is generated again. Parameter setting The service signal is not active in the factory default settings of the TEBS E Modu- lator. Activation and entering the interval is done via tab 8, General functions.

  • Page 52: Axle Load Output

    Transfer of the axle load to the towing vehicle via CAN is configured as default in the TEBS E and can be displayed in the dashboards of most towing vehicles. If in the case of trailers with two axle load sensors the loading state output is not indicated correctly in the towing vehicle, the transfer of the CAN messages can be adjusted.

    With tag axles, the wheel speed must be sensed and braking controlled via a sepa- rate modulator. WABCO recommendation: Brake the tag axle using an EBS relay valve (4S/3M system). An external axle load sensor e-f must also be installed to measure the bellows pressures on the tag axle.

  • Page 78: Traction Help

    TEBS E GIO functions Traction help Vehicle type All air suspended trailer vehicles with lifting axle or tag axle as first axle. Purpose On slippery ground or on steep hills vehicles have a hard time pulling away or can- not do so at all. The drive axle of the towing vehicle does not have enough traction and the wheels spin.

  • Page 80 This is also switched off when the preset threshold value (speed and pressure) is reached. Traction help can be activated by engaging the reverse gear. The ca- ble to the reversing light must be monitored by TEBS E or ELEX for this purpose. Connection, switch The following cabling options can be considered for installing the switch.

  • Page 81: External Axle Load Sensor

    Vehicle type Vehicles with hydraulic suspension for example because suspension pressures of up to 200 bar are required here (vehicles that cannot be connected to the TEBS E Modulator because of too high pressures). The external axle load sensor may be retrofitted on the main axle should the inter- nal sensor fail.

  • Page 82: Dynamic Wheelbase Control

    The function is deactivated once the vehicle had driven through the curve. • Only with partial/full load: With unladen vehicles, the function remains deacti- vated automatically. The TEBS E switches to the automatic lifting axle function.
  • Page 83 Board. Automatic start of OptiTurn when reversing By means of monitoring the reversing light via TEBS E or ELEX Opti- Turn is started automatically with reverse driving. The function is deac- tivated again after a longer stationary periods or when the vehicle moves forward.

  • Page 84: Drawbar Load Reduction (Optiload Tm )

    In this case, the rear axle of the semitrailer acts as a counterweight to the load. After the ignition is turned on, TEBS E determines the load status and relieves the last axle if applicable.
