3. from the zone where there is the RF cable start applying the adhesive aluminium tape antenna sensor practising a good pressure to make it well adhere to the inner surface of the bumper RF Cable Antenna sensor When the antenna sensor has been attached covering the whole of the bumper from left to right the excess length is cut off Place a piece of the included sticking material at either ends of the antenna sensor to ensure a secure fixing onto the bumper surface It is recommended but not essential to cover the antenna with a black anti rust protection paint of the same type that is applied to the underneath of a car chassis or similar to protect from the elements do not use silicon paste Sticking material Antenna sensor Connect the RF Cable coming from the ECU to the antenna sensor Apply a piece of sticking material on the connection and fix iton the bumper by a strong pressure If the ambient temperature is below 10 C we recommend heating both the mastic and the sticking area on the bumper It is necessary to use the same material to fix the opposite extremity of the antenna Fig 5 Replace the bumper and pull the RF Cable inside the luggage compartment or engine compartment in order not to leave excess cable outside Sticking material RF Cable Fig 5 ELECTRICAL CONNECTIONS a Connect the red lead of the power cable to the positive cable that feeds the reversing lamp b Connect the bl

5. the lateral edges the distances is less see Figure 6 The alert occurs only when the vehicle is approaching an obstacle a fixed object in front of the bumper is only detected after the first movement of approach WARNING 1 In presence of rain or high moisture weather the system reduces his sensibility automatically in order to eliminate a part of false alarms that could be given by movement of water on the bumper 2 As soon as the system is activated an acknowledgement of the surrounding of the bumper is made Consequently it is very important during testing operation not to switch on the system while you are very close to the central unit and antenna sensor in order not to have false information on the working capability of the system During the test you must also take into consideration the fact that after the first approach to the bumper any subsequent APPROACH without first reset the system can give false interpretations of the functionality of the sensor due to special characteristics of the EPS DUAL 2 0 software specifically created to reduce false signalling in the rainy conditions ALERT SIGNAL ALARM SIGNAL RISK OF CONTACT SIGNAL Fig 6 Antenna sensor Central module ECU To back gear lamp Buzzer Sensibility switch position white color Sensibility 1 Sensibility 3 Sensibility 4 from 20 to 90 C
6. IROXEL PROXIM LHECTRONICS INSTALLATION INSTRUCTIONS amp USER MANUAL Rear parking sensor mod EPS DUAL 2 0 EPS DUAL 2 0 can be installed only on rear bumper The sistem is strictly a driver assistance device and should not be relied upon as a A security device or a substitute for safe driving practices Use common sense when reversing and always follow recommended safe driving guidelines a The installation of the antenna sensor constituted by an aluminium adhesive ribbon must be performed to the inside of the bumper It is of some importance that the zone of application on the inside surface of the bumper corresponds to the higher part as regards the ground but also the most distant from the car body It is not advisable to install the antenna sensor too low Correct zone b Disassemble the bumper STARTING PROCEDURE a Identify on the car body the zone close to the extremity of the bumper and on the side where it is present the back gear lamp a possible hole of passage toward the intern of the trunk in order to carry out the RF cable from the antenna sensor b Through the individuated passage route the RF cable inside the trunk leaving the fast on terminal outside Fig 2 Thoroughly clean with alcohol or nitre solvent be careful not to use anti adhesive detergent the inner surface of the bumper of the zone previously identified see Fig 1 on which will be applied the antenna sensor Starting
