b) Starting from about 1 meter away from the center of the bumper, slowly
approach both hands to simulate a parking maneuver. At a distance of about
40/50 cm will be heard the first intermittent signals and then a contnuous
higher frequency sound at about 10-15 cm from the bumper.
WARNING: For a correct simulation be carefull to reset the system every time
you approach.
c) If the system shows to work regularly it is possible to fix definitely the
bumper.
Note: EPS-DUAL FRONT 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
signaled and it is not bothered the normal operation of the device.
USER MANUAL
OPERATING PRINCIPLE
EPS-DUAL FRONT is an innovative parking sensor that uses low energy
electromagnetic waves and is able to detect the approach of any kind of
obstacle .
The activation of the device is obteined by pressing the activation button and
confirmed by a signal of “OK". Once activated, the EPS-DUAL FRONT
generates around the bumper, on which is installed, a protection zone (Fig. 6).
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 FRONT is activated the control functionality of
the system is carried out in a fraction os second.
In case of anomalies the speaker emits an audible warning signal consisting of
2 notes (one high and one low) repeated 3 times. If this happens check the
antenna connection to the ECU.
If the control is OK you hear a signal of one single note 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 40/50 cm with 2 types of sounds:
1) an increase in sequence of "BIP" (alert) when the obstacle comes close
to the bumper at a distance between 15 and 60 cm measured on the middle of
bumper.
2) continuous sound at a more acute frequency (risk of contact) when an
obstacle is very close to the bumper (10-15 cm).
Note:
- The device should be activated only during parking maneuvers.
- The distances will vary depending on the size of the obstacle and correspond
to the central zone of the bumper; on 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 FRONT software.
