5. Configuração e instalação
Proper installation is crucial for the reliable operation of the pressure switch. Refer to local codes and regulations.
5.1 Montagem
- Choose a location free from excessive vibration, moisture, and extreme temperatures.
- Mount the switch securely using appropriate fasteners. Ensure the mounting surface is stable.
5.2 Conexão de Pressão
- Connect the 3/8 inch NPT pressure port of the switch to the system's pressure line.
- Use appropriate thread sealant (e.g., PTFE tape) to ensure a leak-free connection.
- Do not overtighten the connection, as this can damage the port or the switch.
5.3 Fiação elétrica
- Ensure all power is disconnected at the source before wiring.
- Open the electrical cover of the switch.
- Connect the electrical wires according to the wiring diagram provided inside the switch cover or in the specific product documentation.
- Use properly sized conductors and ensure all connections are secure.
- Close the electrical cover securely to maintain the IP rating.
6. Instruções de operação
The Danfoss RT200 Pressure Switch operates by sensing pressure and activating or deactivating an electrical circuit when the pressure reaches a predefined set point.
6.1 Setting the Pressure
- Refer to the internal adjustment mechanism (typically a screw or dial) for setting the desired cut-in or cut-out pressure.
- Use a calibrated pressure gauge to monitor the system pressure while adjusting the switch.
- Turn the adjustment screw clockwise to increase the set point and counter-clockwise to decrease it.
- Test the switch operation multiple times to confirm the set point accuracy.
6.2 Differential Adjustment (if applicable)
Some models allow for adjustment of the differential (the difference between cut-in and cut-out pressure). Consult the specific product diagram for details on adjusting this setting.
7. Manutenção
The Danfoss RT200 Pressure Switch is designed for minimal maintenance. However, periodic checks are recommended to ensure continued reliable operation.
- Inspeção visual: Inspecione regularmente o interruptor para verificar se há sinais de danos físicos, corrosão ou conexões soltas.
- Verificação de vazamentos: Periodically check the pressure connection for any leaks.
- Teste funcional: If critical, periodically test the switch's operation by simulating pressure changes to verify it switches at the correct set points.
- Limpeza: Keep the exterior of the switch clean and free from dust and debris. Do not use harsh chemicals that could damage the enclosure.
8. Solução De Problemas
If the pressure switch is not functioning as expected, refer to the following table for common issues and their potential solutions.
| Problema | Possível causa | Solução |
|---|---|---|
| Switch does not activate/deactivate | No power; Incorrect wiring; Pressure outside range; Faulty switch | Check power supply; Verify wiring against diagram; Check system pressure; Replace switch if faulty |
| Inaccurate switching point | Incorrect set point adjustment; Clogged pressure port; Sensor issue | Re-adjust set point; Clean pressure port; Contact Danfoss support if sensor is suspected faulty |
| Leaks at pressure connection | Improperly sealed threads; Damaged connection | Re-apply thread sealant and re-tighten; Replace connection if damaged |
| Operação intermitente | Loose electrical connections; Vibration; Pressure fluctuations | Tighten connections; Isolate from vibration; Stabilize system pressure |
Se as etapas de resolução de problemas não resolverem o problema, entre em contato com o suporte técnico da Danfoss ou com um técnico de serviço qualificado.
