Proxel EPS-DUAL 4.0 Rear Parking Sensor

STARTING PROCEDURE

a) The installation of the antenna sensor, constituted by an aluminum adhesive ribbon, must be applied to the inner surface of the bumper. It is of some importance that the zone of application corresponds to the higher part as regards the ground but also the most distant from the car body.
b) 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 on the data cable to the antenna sensor.

POSITIONING OF ANTENNA SENSOR

A- Thoroughly clean with alcohol or niter solvent the inner surface of the bumper of the zone previously identified on which will be applied the antenna sensor.
B- Fix through its adhesive the black connection module of the data cable on the inner surface of the bumper at approximately 10 cm away from the wheel.

C- Connect the black module of the Data cable coming from the ECU to the antenna sensor. and fix it on the bumper by a strong pressure. When arrived at the opposite side of the bumper cut off the antenna in excess and fix the extremity using a piece of sticking material

ELECTRICAL CONNECTIONS

( Fig.2)

a) Connect the red lead of the power cable to the positive cable that feeds the reversing lamp.
b) Connect the black lead of the power cable to the earth of the reversing lamp.

NOTE: Some vehicles are equipped with a metal crash protection bar insert facing the inside surface of the bumper. When this metal surface is too close to the inner surface of the bumper where you have placed the antenna sensor. the detection distance can be reduced.

However. you can increase the sensitivity by changing the position of slide switch (see FIG 3).

SENSITIVITY:

1. LOW
2. NORMAL
3. MEDIA Fig.3
4. HIGH

TESTING PROCEDURE

a) Turn on the key, insert the back gear. In a fraction of second the control unit performs a check of the functionality of the system and, if everything has been done correctly, the buzzer emits an acoustic sound of “OK” (two notes in rapid succession). Once you have this signal the system becomes operational.

VERY IMPORTANT is not to carry out experimental tests (on bench) before having completely assembled the kit with the antenna applied to the bumper because the system does not work properly without the presence of the metal mass of the vehicle Possible problems and their solutions

1. If the buzzer produces 8 consecutive fast beeps control the data cable and its connection to the control unit and that there is not a short circuit between the antenna sensor and the metal body of the car.
2. lf the transducer emits an audible warning signal consisting of 2 notes (one high and one low) repeated 3 times check the connection of Data cable with antenna sensor.
   b) Starting from about 1 meter away from a wII, approach very slowly to simulate a parking maneuver. At a distance of about 60/70 cm will be heard the first acoustic signals whose repetition rate will increase at the decreasing distance to become a fast intermittent sound and then a continuous higher frequency sound at about 10-15 cm from the bumper.
   c) If the system shows to work regularly it is possible to fix definitely the bumper.

Notes: EPS-DUAL 4.0 starts to give the signaling only when the vehicle is being approached to the obstacle; a fixed object in front of the bumper. for instance the hauls hook and a bull bar or the sides walls of a car box, is not signal led and it is not bothered the normal operation of the device. . If the license plate covers the antenna sensor. ,t does not alter its ability to detect obstacles in front of it.

The activation of the device is obtained by the insertion of the back gear and confirmed by a signal of “OK”. Once activated, the EPSDUAL 4.0 generates around the bumper, on which is installed, a protection zone (Fig. 1 ). When any obstacle present in the protection zone tends to approach the bumper you will hear a series of beeps.

WORKING EXAMPLE

A) As soon as the EPS-DUAL 4.0 is activated the control functionality of the system is carried out in a fraction of second.
If the control is OK you hear a signal of two notes in rapid succession to confirm the proper functioning of the system.
B) When approaching an obstacle the system activates the acoustic signal at a distance between the bumper and obstacle (measured in the central area of the bumper) of about 70 / 80 cm with 3 types of sounds:

1. an increase in sequence of “BIP” (alert) informs the driver that an obstacle is approaching.
2. intermittent sounds of fast repetition rate when the obstacle comes close to the bumper at a distance between 15 and 30 cm measured on the middle of bumper (alarm).
3. continuous sound at a more acute frequency (risk of contact) when an obstacle is very close to the bumper (10-15 cm).

Note:

• The detection is depending on the size of the obstacle and while the max corresponds to the central zone in the lateral edges the distances of detection are less ( see Fig. 1)
• 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.
• The ON I OFF switch on the buzzer is blocked because it cannot be used in this version.

WARNING

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 near the antenna.

ELECTRICAL CHARACTERISTICS

• Operating Voltage from 9,5 to 18V
• Average current absorption 20 mA
  

STARTING PROCEDURE

a) The antenna sensor, constituted by a very strong aluminum adhesive tape, must be applied to the inner surface of the bumper and in the higher part as regards the ground.
b) Locate a passage where, from the driver’s place behind the dashboard, it is possible to route the DATA CABLE into the engine compartment up to the extremity of the bumper.

We suggest to use the interspace that is spearing the engine compartment from the lateral outside surface of the car body. The right place where to find it is close the driver door hinge.

MOUNTING THE ANTENNA SENSOR

A- Thoroughly clean with alcohol or nitro solvent the inner surface of the bumper of the zone previously identified on which will be applied the antenna sensor.
B- Place the black fast-on connector of the data cable to the internal surface of the bumper using its double-sided tape, starting from about 1 0-15 cm from the bumper end and connect the antenna sensor.
C- Coat the connection with a piece of adhesive putty.

After connecting the antenna sensor, you can start placing the tape on the bumper by applying strong pressure in order to make i ad here well I to its internal surface. After application, the excess part of the tape can be cut off.
NOTE: Even if the metal license plate covers the antenna sensor, it does not disturb its obstacle detection capacity in that area.

ELECTRICAL CONNECTIONS

The control unit can be placed under the dashboard and the activation button together with the buzzer in a suitable place.
Connect the red wire of the power supply cable to the 12V positive under key and the black cable to a good ground point. Place the activation button in a suitable place on the dashboard and connect the red wire to the plus and the black wire to the minus. The other wo wires to the other two contacts indifferently (Fig.2).

FINAL TESTING PROCEDURE

a) Turn on the key, press the push-button. In a fraction of second the control unit performs a check of the functionality of the system and, if everything has been done correctly, the buzzer emits an acoustic sound of “OK” (one note). Once you have this signal the system becomes operational but automatically deactivates after 2 minutes with a special sound.

VERY IMPORTANT is not to carry out experimental tests (on bench) before having completely assembled the kit with the antenna applied to the bumper because the system does not work properly without the presence of the metal mass of the vehicle.

Possible problems and their solutions

1. If the acoustic transducer does not emit any signal check all the connections.
2. If the transducer emits an audible warning signal consisting of 2 notes (one high and one low) repeated 3 times) check the connections of DATA cable to the antenna sensor.
3. If the buzzer produces 8 consecutive fast beeps check the DATA cable connection on the central unit.
   b) Starting from about 1 meter away from a wall, approach very slowly to simulate a parking maneuver. At a distance of about 50/60 cm the first acoustic signals will be heard, the repetition frequency of which will increase as the distance decreases to first become a fast intermittent sound and then continuous at about 10-15 centimeters from the bumper.

NOTES:

1. EPS-FRONT 4.0 is able to detect obstacles that tend to approach the bumper with an alarm signal all the more prompt and evident the closer the obstacle is located. By activating the warning only when the vehicle is approaching the obstacle, a fixed object in front of the bumper, for example the “bull bar”, the license plate or the side walls of a garage, are not signaled and the normal operation of the device is not disturbed.
2. The front obstacle detection system must obligatorily be controlled via the button only when necessary, as it cannot always remain active during travel as the advancement of the car would continually produce false signals.

The activation of the device is obtained by pressing the activation button and confirmed by a signal of “OK”. Once activated, the EPS-FRONT 4.0 generates around the bumper, on which is installed, a protection zone (Fig. 1 ).

When any obstacle present in the protection zone tends to approach the bumper you will hear a series of beeps.

If you want to deactivate the system, simply press the button a second time and a different acoustic signal warns you of deactivation, otherwise it deactivates automatically after 2 minutes.

When approaching an obstacle the system activates the acoustic signal at a distance between the bumper and obstacle (measured in the central area of the bumper) of about 50/70 cm with 3 types of sounds:

1. an increase in sequence of “BIP” (alert) informs the driver that an obstacle is approaching.
2. intermittent sounds of fast repetition rate when the obstacle comes close to the bumper at a distance between 15 and 30 cm measured on the middle of bumper (alarm).
3. continuous sound at a more acute frequency (risk of contact) when an obstacle is very close to the bumper (10-15 cm).

Note:

• The distances will vary depending on the size of the obstacle and corresponds to the central zone of the bumper; on the lateral edges the distances is less (Fig. 5)
• 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 approaching.
  The ON I OFF switch on the buzzer is blocked because it cannot be used in this version.

WARNING

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.

In this situation, the alarm zone could be eliminated and only the risk of contact signal maintained (Fig. 1 ).
