2. Painting the Sensors
Follow these steps to paint the sensors for a seamless integration with your vehicle's color:
- Preparation:
For BL-412PM sensors, remove the plastic rings. Note: The silicon rubber is not removable; do not attempt to remove it ?.
Visual Description: An illustration shows a sensor with a plastic ring that should not be removed.
- Sanding:
Sand the surface of the sensors with a fine sandpaper (1000 or 1200 grit) to ensure better paint adhesion. Clean the sensor surface thoroughly to remove any sanding dust.
- Masking:
Place the sensors inside the provided paint mask box.
Visual Description: An illustration shows four sensors placed inside a white box labeled "Paint Mask".
- Spray and Paint:
Apply a thin coat of paint. Allow it to dry, then apply another coat for better paint coverage. Paint the plastic rings together with the sensor heads.
Visual Description: An illustration shows a spray gun painting sensor heads and their rings.
3. System Overview
The system provides parking assistance for vehicles.
For a Passenger Car
Visual Description: A top-down view of a car's rear bumper area shows the placement of four sensors. The control box is depicted inside the vehicle, and a speaker unit is also shown. The text indicates that the speaker unit is for distance indication, and closer proximity to objects results in a shorter pitch sound. The control box is not waterproof and is recommended to be placed under the driver's seat.
Placement: Place the speaker and control box inside the vehicle. Avoid water damage. The speaker unit provides auditory feedback for distances to objects, with shorter pitch sounds indicating closer proximity.
Control Box Location: The control box is not waterproof; it is recommended to place it under the driver's seat.
For a Truck
Visual Description: A diagram illustrates the installation in a truck. It shows a video wire from a camera connected to a monitor unit. The speaker unit is labeled for distance indication. The control box is shown, with a note that it is not waterproof and should be placed under the driver's seat. Extension cables are also depicted.
Connections: Video wire from a camera to be connected to a monitor unit. The control box is not waterproof and is recommended for placement under the driver's seat. Extension cables are used for routing.
4. Installation
Proper installation is crucial for both appearance and system functionality.
- Sensor Placement:
Sensors should be mounted at 90° angles to the ground. Avoid obstructions caused by bumper shape for optimal operation.
- Height Measurement:
Measure the height on the bumper for proper installation locations. The diagram indicates a maximum height (L max) and specific measurements for sensor spacing (e.g., 1/8, 1/4, 1/4, 1/8 from the edges).
Visual Description: A diagram shows a bumper edge with measurements indicating sensor spacing. A tape is placed over the intended installation location. The ground is indicated.
- Mounting:
Generally, mount sensors as high as possible in the bumper. Use paint masking tape to mark locations according to the diagram for proper spacing.
- Important Pre-Drilling Check:
⚠️ MUST CHECK BEHIND THE BUMPER FOR ANY METAL BRACKETS OR INTERNAL BRACES BEFORE DRILLING ⚠️
- Drilling:
Ensure the bumper surface and sensors fit at 90° to the ground. Clean the hole surface. Start cutting the bumper surface in a counter-clockwise direction (A) to prevent paint chipping, then drill the hole in a clockwise direction (B).
Visual Description: A diagram shows a bumper with a hole being drilled. Arrows indicate counter-clockwise drilling (A) and clockwise drilling (B). A number '3' points to the sensor installation area.
- Sensor Orientation:
BL-412PM sensors must be installed from the outside of the bumper. Check the direction dot (WHITE) and ensure correct orientation.
Visual Description: An illustration shows a sensor being installed from the outside of a bumper, highlighting a white dot indicating its orientation. A button labeled "Check for the direction" is shown.
- Hole Size:
It is important not to drill the hole larger than the indicated measurement. MUST use the provided hole saw.
- Wire Routing:
Route the sensor wires through the bumper to a suitable location in the vehicle trunk or rear hatch.
- Control Unit Connection:
Connect the main control unit RED wire to a positive charge wire of the vehicle's back-up light. Connect the main control unit BLACK wire to a stable ground.
- Sensor Installation:
After routing and attaching cables, use a block (e.g., small block of wood) to press the sensors into place. NEVER push the sensor heads (center portion) into the bumper.
Visual Description: An illustration shows a sensor being pushed into a bumper hole using a block of wood. It emphasizes not to push the center of the sensor head.
? Important Notes:
- Do not use the negative charge wire of the vehicle's back-up light for ground. Some vehicles have a "check bulb" feature that makes that wire not a true ground.
- The system may not detect a small and round pole (such as a fire hydrant or light pole, etc).
- When the vehicle approaches a rising slope, the slope may not be detected, as most of the signal will be reflected up and not back at the vehicle.
5. Detecting Range
The sensors' normal detection range is up to 8 feet.
Visual Description: Diagrams illustrate the detection zones of the parking sensors from both a top-down view and a side view of a vehicle. The detection cones show the area around the rear of the vehicle where objects can be detected.
