4. Configuração e instalação
4.1 Montagem
The SM31R sensor is designed for easy mounting using its integrated threaded barrel. Secure the sensor firmly in the desired position, ensuring it has a clear line of sight to the corresponding emitter (if applicable for through-beam mode) or the target object (for diffuse mode).
- Certifique-se de que a superfície de montagem seja estável e livre de vibrações excessivas.
- Position the sensor to avoid direct sunlight or other strong light sources that could interfere with its operation.
4.2 fios
The SM31R comes with a 2-meter cable. Refer to the wiring diagram on the sensor label (Figure 3.2) and the table below for correct connections. Always ensure power is disconnected before wiring.
| Cor do fio | Função | Descrição |
|---|---|---|
| Marrom | Entrada de energia (+) | +10 a 30 VCC |
| Azul | DC Common (-) | Ground / 0 VDC |
| Branco | Output 1 (NPN) | Sink output, 150mA max |
| Preto | Output 2 (PNP) | Source output, 150mA max |
Connect the sensor outputs to your control system (PLC, relay, etc.) according to your application's requirements. The SM31R provides both NPN (sink) and PNP (source) outputs simultaneously.
5. Instruções de operação
Once properly installed and wired, the SM31R sensor operates automatically. It functions as a receiver in a through-beam setup or as a diffuse sensor, detecting objects within its 3-meter range.
5.1 Ligar
Apply 10-30 VDC power to the sensor. The sensor will typically have an indicator LED (if present) to confirm power and output status.
5.2 Detecção
When an object enters the sensor's detection field (up to 3 meters), the output state will change according to its configuration (light operate or dark operate, depending on the specific model and setup). The NPN and PNP outputs will switch simultaneously.
5.3 Alignment (for Through-Beam applications)
For through-beam applications, ensure the SM31R receiver is perfectly aligned with its corresponding emitter. Most Banner Engineering sensors have alignment indicators (LEDs) to assist with this process. Maximize the signal strength for reliable operation.
6. Manutenção
The BANNER ENGINEERING SM31R sensor is designed for minimal maintenance. However, regular inspection and cleaning can prolong its lifespan and ensure consistent performance.
- Limpeza: Limpe periodicamente a lente e o corpo do sensor com um pano macio e seco.amp cloth. Do not use abrasive cleaners or solvents that could damage the plastic.
- Inspeção: Regularly check the cable for any signs of damage, fraying, or wear. Ensure all connections are secure.
- Verificação ambiental: Verify that the operating environment remains within the sensor's specified limits (temperature, humidity, presence of corrosive substances).
7. Solução De Problemas
If the SM31R sensor is not functioning as expected, refer to the following common issues and solutions:
| Problema | Possível causa | Solução |
|---|---|---|
| O sensor não liga. | No power supply; Incorrect wiring; Power supply voltage fora do alcance. | Check power connections (Brown to +V, Blue to 0V); Verify power supply is 10-30 VDC; Check for blown fuses or tripped breakers. |
| Sensor not detecting objects | Misalignment (through-beam); Lens dirty; Object too far/close; Incorrect sensing mode; Damaged sensor. | Re-align emitter/receiver; Clean sensor lens; Verify object is within 3m range; Check sensor type (diffuse/through-beam); Replace sensor if damaged. |
| Erratic or inconsistent output | Interference from ambient light; Vibration; Loose wiring; Contaminated lens. | Shield sensor from strong light; Secure mounting; Check all wiring connections; Clean lens. |
| Output stuck ON or OFF | Short circuit in wiring; Overload on output; Internal sensor failure. | Inspect wiring for shorts; Ensure output current does not exceed 150mA; Contact Banner Engineering support if issue persists. |
