1 Commercial Vehicle Systems Product DATA Function The function uses the lateral accelerometer integrated in the TEBS Brake Module to monitor any lateral tilting of the trailer during the tipping operation. If the tilt angle exceeds a programmable threshold then the Brake Module will generate an electrical or pneumatic output which can be used as a driver warning or intervene in the tipping operation. PD--F0 Operation The lateral acceleration sensor, used primarily for the Roll Stability Program (RSP), may also be used to define the lateral angle of the trailer platform. Therefore, when a predefined lateral angle is exceeded, an electrical output will be generated from the configured AUXIO or a pneumatic signal from the P 8 output. This function is of value to tipping trailers where, due to irregularities in the surface on which the trailer is standing, the trailer may tip over as the body is lifted to off-load the contents of the body. The output from the Brake Module may be connected to produce the following possibilities: Connect to an audible warning system to alert the operator of a potential problem. Connect to the tipping control system to prevent the body from being lifted further. Connect to the tipping control system to automatically lower the body. The tilt angle may be set at any angle between and 5 (hysteresis 0. ). The output is generated up to a predefined maximum speed within the range 0 to 5 km/h (default setting is km/h). Once the defined speed has been exceeded the output will be suppressed. When the speed falls below the defined maximum speed less 5%, the output will be reinstated. The electrical signal can be set to switch between 0 V and V avg or, in inverted mode, between V avg and 0 V. is active (when configured) without the need for any switch or sensor (BLS) to detect that the body is lifted. However, if a sensor (BLS) or detection (BLD -. Standard (CN00 and above)/standard Plus/ Premium) is configured and is not active (i.e. body lowered) then the TA output will always be suppressed. Note: The number of occasions when the tilt angle output is activated is stored in the operational data recorder (ODR). See PD--F5, Document No. Y6.

2 PD--F0 Product Data Installation restrictions when using TA When TA is configured it is important for the Brake Module that during installation the lateral angular displacement is controlled to ensure the output from the internal lateral acceleration sensor is accurate and therefore able to allow effective TA control. The lateral installation angle A which must be kept within +/-5 of horizontal. Note that this value is checked during the EOL test. In the longitudinal and vertical planes the installation tolerance is +/- 0 Lateral installation angle A +5-5 DU-00b-TEBS-G Setting up of related parameters.0, G. and G. Standard up to CN0 In ECUtalk under the tab Auxiliary I/O use the Change configuration option. From the drop down list for the required AUXIO select Output, then TA. Select the Error detection and voltage ( V avg ) options to suit what is connected to the output:

the Body Lift Emergency Function (BLEF) to determine the speed at which the function makes an automatic application of the brakes.
