4. Configuració
4.1 Desembalatge
Carefully remove the sensor and any accessories from the packaging. Inspect all components for any signs of damage. Retain the packaging for future transport or storage.
4.2 Muntatge
Mount the LR-TB5000C sensor using the provided mounting bracket and hardware. Ensure the sensor is securely fastened to a stable surface. Position the sensor so that its detection area is clear and unobstructed.
4.3 Cablejat
Connect the M12 connector cable to the sensor. Ensure proper polarity for the power supply (20 to 30 VDC). Connect the control output (NPN/PNP open collector) and analog output (current/voltage selectable) to your control system as required. Refer to your system's wiring diagram for specific connections.
5. Instruccions de funcionament
5.1 Encès
Once wired correctly, apply power to the sensor. The indicator lights on the sensor will illuminate, indicating it is powered on and ready for operation.
5.2 Funcionament bàsic
The LR-TB5000C can detect objects within a range of 60 to 5000 mm. The spot diameter is variable; ensure it is set to 40 mm or less for optimal performance. The sensor uses a red laser (660 nm) for detection.
5.3 Funcions del temporitzador
The sensor offers selectable timer functions: OFF, OFF delay, ON delay, and One-shot. Configure these settings via the sensor's interface or connected control system as per your application requirements.
5.4 Mutual Interference Prevention
When using multiple LR-TB5000C sensors in close proximity, enable the mutual interference prevention function. This allows up to 4 units to operate without interference.
6. Manteniment
Regular maintenance ensures optimal performance and longevity of the sensor.
- Neteja: Periodically clean the lens cover and display with a soft, dry cloth. Avoid abrasive cleaners or solvents.
- Inspecció: Check cables and connectors for damage or wear. Ensure mounting hardware remains secure.
- Condicions ambientals: Verifiqueu que l'entorn operatiu es mantingui dins dels rangs de temperatura i humitat especificats.
7. Solució De Problemes
If the sensor is not functioning as expected, refer to the following common issues and solutions:
- Sense energia: Comproveu les connexions de la font d'alimentació i el volumtage. Ensure the power source is active and within 20-30 VDC.
- Sense detecció: Verify the sensor's alignment with the target. Check the detectable distance setting. Ensure the lens is clean and unobstructed.
- Incorrect Output: Confirm the NPN/PNP or analog output settings are correct for your control system. Check wiring for continuity and correct connections.
- Interferència: If multiple sensors are used, ensure the mutual interference prevention function is enabled.
