5 Required components: Overview
This chapter gives an overview of the components that are required for the following three TailGUARD™ variants.
Further details can be found in Chapter 6 of the system description for TailGUARD™ for Truck & Bus.
To avoid any accidents, observe the following safety instructions for vehicles with braking intervention
through TailGUARD:
„
Because the stopping distance becomes longer with heavily laden vehicles
- in particular when it is equipped with EBS - the settings (parameter
setting / pressure limiting valve) must enable sufficient deceleration for the
fully laden vehicle.
„
Note pulsed braking when reversing too fast:
„
TailGUARD can assist only with reversing speeds below max. 9 km/h.
„
TailGUARD will trigger short brake pulses when a critical speed is
reached to alert the driver.
„
If the driver accelerates further, TailGUARD deactivates itself and
outputs a fault message.
„
In the case of EBS vehicles with brake intervention via separately
installed valves, ABS functions are not available during TailGUARD
braking. Even at the low speed range at which TailGUARD is active, the
wheels might lock on slippery surfaces.
„
Speed signal faults due to incorrect or unprofessional connection can
significantly impair vehicle safety.
„
Vehicles with a prepared interface for TailGUARD: TailGUARD may not
brake if the vehicle’s EBS system has a fault.
5.1 Variant: Only monitoring and warning
If TailGUARD™ is only to be used for monitoring and warning purposes (see Section 4.1, first variant), the following
components are required:
„
2 to 6 ultrasonic sensors depending on your own requirements, as well as the number of installation locations that
are possible on the refuse collection vehicle in question.
„
The appropriate extension and splitter cables for connecting the ultrasonic sensors to the Electronic Extension
Module.
„
The Electronic Extension Module (also referred to here as the ECU), which contains the control electronics and
provides all the required sockets for the connecting cables. The ECU is usually mounted on the frame of the
vehicle as close as possible to the drive axle. The ECU must always be installed so that the cable openings point
downwards or to the side.
„
A Trailer Remote Control in the vicinity of the driver's seat for optical and acoustic indication of the detected
distances, as well as for warning purposes. The Trailer Remote Control also allows the driver to manually adjust the
volume of the acoustic indicator and to temporarily disable TailGUARD™.
„
A special supply cable for the power supply to the ECU, which is fed to terminals 15, 30 and 31 in the fuse box or
the vehicle's electrical compartment. The Trailer Remote Control is also connected to terminals 15 and 31 of this
line link to supply it with voltage. In addition, the Trailer Remote Control communicates with the ECU via this line
using the PLC method: "PowerLine Communication" uses a power supply line to simultaneously transmit electrical
signals.
