Información de seguridad

Tenga en cuenta las siguientes precauciones de seguridad durante la instalación y el funcionamiento:

• Always disconnect power to the air compressor system before installing or servicing the pressure switch.
• Asegúrese de que todas las conexiones eléctricas estén seguras y aisladas para evitar cortocircuitos y riesgos eléctricos.
• Verify that the pressure switch's ratings (PSI, ampedad, voltage) sean compatibles con su sistema de compresor de aire.
• Use appropriate thread sealant on the 1/8" NPT connection to ensure an airtight seal.
• It is recommended to use this pressure switch in conjunction with a relay to handle the compressor's current draw, especially for higher amperage systems.
• Do not exceed the maximum operating pressure or temperature ratings of the switch.

The VIAIR 90217 Pressure Switch is a critical component for automated air management systems. It provides reliable control by sensing air pressure and activating or deactivating an air compressor accordingly. Its sealed design offers resistance to moisture, enhancing durability in various environments.

Características principales:

• Automatically turns air compressor on at 110 PSI y off at 145 PSI.
• Cuenta con una 1/8" Male NPT Thread para una conexión segura.
• Rated for use with 12 & 24-volt systems, up to 30 amps.
• Diseñado con un construcción sellada for moisture resistance.
• VIAIR recommends using this pressure switch with a relay for optimal performance and longevity.

Instrucciones de instalación

Montaje

1. Identify a suitable 1/8" NPT female port on your air tank or manifold.
2. Apply an appropriate thread sealant (e.g., PTFE tape or liquid sealant) to the 1/8" Male NPT threads of the pressure switch.
3. Carefully thread the pressure switch into the port. Tighten until snug, ensuring an airtight seal, but do not overtighten to avoid damaging the threads or the switch.

Alambrado

The pressure switch acts as a control signal for your compressor. It is a Normalmente abierto switch, meaning the circuit is open (compressor off) when pressure is above 145 PSI, and closes (compressor on) when pressure drops below 110 PSI.

1. Ensure the power source to the compressor system is disconnected.
2. Connect the two terminals of the pressure switch into the control circuit of your air compressor system.
3. For systems drawing more than a few amps, it is strongly recommended to wire the pressure switch to control a relé. The relay will then handle the high current draw of the compressor motor, protecting the pressure switch from excessive load.
4. Ensure all wiring is correctly sized for the ampmedia y voltage of your system (up to 30 amps para 12 & 24-volt systems) and properly insulated.
5. After wiring, double-check all connections for security and correct polarity before restoring power.

Operación

Once correctly installed and wired, the VIAIR 90217 Pressure Switch operates automatically. When the air pressure in your system drops to 110 PSI, the switch will close its internal contacts, sending a signal to turn on the connected air compressor. The compressor will continue to run until the system pressure reaches 145 PSI. At this point, the switch will open its contacts, turning off the compressor. This cycle repeats as needed to maintain pressure within the specified range.

Mantenimiento

The VIAIR 90217 Pressure Switch is designed for minimal maintenance. However, periodic inspection can help ensure its continued reliability:

• Inspección visual: Revise periódicamente el interruptor para detectar cualquier signo de daño físico, corrosión o conexiones sueltas.
• Integridad de la conexión: Ensure the NPT threaded connection remains tight and free of leaks. Check electrical connections for tightness and proper insulation.
• Limpieza: Keep the exterior of the switch clean and free from excessive dirt or debris. While sealed for moisture resistance (IP54), extreme conditions or prolonged exposure to contaminants can affect performance.
• Verificación de funcionalidad: Periodically verify that the compressor turns on and off at the specified pressure points (110 PSI ON, 145 PSI OFF).
