4. Kuweka na Kuweka
4.1 Kuweka
Securely mount the sensor using appropriate hardware in a location that provides a clear line of sight to the target object and is free from excessive vibration or impact.
Wiring
The LR-W500C sensor uses a 4-pin M12 connector. Refer to the diagram below and the sensor's label for correct wiring. Ensure power is disconnected before making any connections.
| Bandika | Rangi ya Waya | Kazi |
|---|---|---|
| 1 | Brown | Power (10-30V DC) |
| 2 | Nyeupe | Ingizo la Nje |
| 3 | Bluu | 0V (Chini) |
| 4 | Nyeusi | Output (50mA) |
After wiring, ensure all connections are secure and insulated.
5. Maagizo ya Uendeshaji
5.1 Washa umeme
Once wired correctly, apply power (10-30V DC) to the sensor. The STB (Stability) indicator will illuminate.
5.2 Uteuzi wa Njia
The sensor features a MODE button to cycle through different operating modes:
- NO/NC (Normally Open/Normally Closed): Press the MODE button briefly to toggle between Normally Open (NO) and Normally Closed (NC) output configurations.
- Kuzingatia: Press and hold the MODE button for approximately 3 seconds to enter Focus mode, allowing for fine-tuning of the detection area.
5.3 Setting Detection
Use the SET button to teach the sensor the desired detection threshold. Follow the specific instructions for your application to set the sensor accurately.
Taa 5.4 za Kiashiria
- STB (Stability): Indicates the stability of the detection. A steady light typically means stable operation.
- C (Control Output): Illuminates when the control output is active (e.g., an object is detected).
- I (Input): Indicates the status of the external input.
6. Matengenezo
Regular maintenance ensures the longevity and reliable operation of your sensor.
- Kusafisha: Gently wipe the sensor lens and housing with a soft, dry cloth. For stubborn dirt, use a cloth lightly dampened with a mild, non-abrasive cleaner. Do not use organic solvents.
- Ukaguzi: Periodically check wiring for damage or loose connections. Ensure the sensor is securely mounted.
- Zima umeme: Always disconnect power to the sensor before performing any cleaning or inspection.
7. Utatuzi wa shida
If the sensor is not operating as expected, refer to the following common issues and solutions:
- Sensor not powering on:
- Angalia usambazaji wa umeme voltage (10-30V DC).
- Verify wiring connections (Brown to +V, Blue to 0V).
- No detection or unstable detection:
- Ensure the sensor lens is clean and free from obstructions.
- Check the detection distance; it should be within 30-500mm.
- Re-perform the SET procedure to teach the sensor the target.
- Adjust the sensor's position or angle relative to the target.
- Check for excessive ambient light or reflective surfaces interfering with detection.
- Output not switching:
- Verify the NO/NC setting is correct for your application.
- Check the wiring of the output (Black wire).
- Ensure the load connected to the output is within the sensor's current capacity (50mA).
If problems persist, contact Keyence technical support.
