3. Usage of Lens Shield
The detector includes two lens shields to mask undesired detection areas. Each shield has three layers (A, B, C), with each layer containing 6 segments, allowing 30° masking per segment.
Example: At a 10m installation height, the detection range varies based on the lens shield used:
| Used Lens Shield | Covered Detection Range |
|---|---|
| None | Φ 16m |
| Small segment | 30° per piece |
| A+B+C | Φ 1m |
| A+B | Φ 12m |
| A | Φ 14m |
The shadowed parts in the diagram (FIG. 1) indicate the cut-off areas. After selecting the desired detection area, remove any redundant lens shields. To fix a lens shield, insert it into the slot around the lens (FIG. 2).
4. Installation
4.1 Select a Proper Location
4.1.1. Mounting Height: The detector can be installed between 2.5m and 10m. For optimal detection (16m diameter, 360° coverage), installation at 10m is recommended (FIG. 3-A, FIG. 3-B).
4.1.2. Movement Direction: The detector is more sensitive to movement across its field of view than directly towards it, which can reduce effective coverage (FIG. 4).
4.1.3. Installation Tips: To ensure accurate detection, avoid the following conditions (FIG. 5-A, FIG. 5-B):
- Pointing towards highly reflective surfaces like mirrors or glass.
- Mounting near heat sources such as heating vents, air conditioners, or lights.
- Aiming at objects that may sway in the wind, like curtains or tall plants.
4.2 Installation Procedure
4.2.1. Flush Mount with European Standard Junction Box
- Remove the decorative frame of the detector (FIG. 6).
- Pull out the KNX bus cable from the European standard junction box.
- Connect the bus cables using the KNX terminal (FIG. 6-A, FIG. 6-B). The terminal has two components (B2.1, B2.2) with four contacts each, suitable for solid conductors (Ø 0.6 - 0.8 mm). Strip 5mm of cable sheathing and insert into the terminal (Red = +, Grey = -).
- Wire correctly as per illustration (FIG. 7) and fix the power box into the European standard junction box using two screws (FIG. 8).
- Re-attach the decorative frame (FIG. 6).
- Restore power supply.
4.2.2. Flush Mount with Power Box Cap (Optional Purchase)
- Drill a 78mm diameter hole in the ceiling board and ensure the cable is accessible. Refer to Section 4.2.1.2 and 4.2.1.3 for cable connection (FIG. 9).
- Break the rubber gasket on the power box cap using a screwdriver and feed cables through it (FIG. 10).
- Wire correctly as per illustration (FIG. 7) and securely screw on the power box cap.
- Compress the two spring clips on the detector and insert it into the drilled ceiling hole (FIG. 11).
- Restore power supply.
4.2.3. Surface Mount with Junction Box (Optional Purchase)
- The junction box has four pairs of knockouts (56mm to 80mm) on its bottom cover for various mounting applications (FIG. 12). Select matching knockouts on both ends for the desired fixing distance (Table-2).
- Feed cables through the side knockout of the junction box. Use cutting pliers to break the knockout, insert cables, and then connect them as per Section 4.2.1.2 and 4.2.1.3 (FIG. 13).
- Fix the junction box to the ceiling surface using two wood screws with rubber washers, selecting appropriate knockouts (FIG. 14).
- Refer to wiring diagrams for correct wiring (FIG. 7). Align the fixing plate's square hole with the protrusion on the junction box (FIG. 15). Then, attach the detector head to the power box using the four provided non-dropping screws (FIG. 6).
- Replace the decorative frame and restore power supply.
5. Troubleshooting
If the detector operates abnormally, consult the following table for potential problems, causes, and solutions:
| Problem | Possible Cause | Suggested Solution |
|---|---|---|
| Lighting / HVAC device does not turn off | 1. Power is not on. 2. Incorrect wiring. 3. Incorrect Lux setting. 4. Malfunctioned load. 5. Unable to detect movement. | 1. Switch on power. 2. Check wiring diagram for correct connection. 3. Verify Lux setting. 4. Replace the load. 5. Check detection range setting. |
| Lighting / HVAC device does not turn on | 1. Auto off time is set too long. 2. Detector is nuisance triggered. 3. Incorrect wiring. | 1. Set a shorter auto-off time and check. 2. Avoid the detection area during testing. 3. Check wiring diagram for correct connection. |
| Red LED does not turn on | 1. Not set to Test mode. 2. Exceeding detection range. 3. LED indicating function is set to "Disable". | 1. Set to Test mode. 2. Ensure movement is within the 16m detection range. 3. Enable LED indication via ETS software. |
| Nuisance triggered | There are heat sources, highly reflective objects, or swaying objects within the detection coverage. | Avoid pointing the detector towards heat sources (air conditioners, heaters), highly reflective surfaces, or objects that sway in the wind (curtains, plants). |
