Uvod
This manual provides instructions for the proper installation, operation, and maintenance of your VIAIR 90217 Pressure Switch. This device is designed to automatically control an air compressor by turning it on at 110 PSI in off at 145 PSI. Adherence to these instructions is essential for safe and effective use.

Varnostne informacije
Med namestitvijo in delovanjem upoštevajte naslednje varnostne ukrepe:
- Always disconnect power to the air compressor system before installing or servicing the pressure switch.
- Ensure all electrical connections are secure and insulated to prevent short circuits and electrical hazards.
- Verify that the pressure switch's ratings (PSI, amperage, zvtage) are compatible with your air compressor system.
- 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.
Konec izdelkaview
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.

Montaža
- Identify a suitable 1/8" NPT female port on your air tank or manifold.
- Apply an appropriate thread sealant (e.g., PTFE tape or liquid sealant) to the 1/8" Male NPT threads of the pressure switch.
- 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.
Ožičenje
The pressure switch acts as a control signal for your compressor. It is a Običajno odprto switch, meaning the circuit is open (compressor off) when pressure is above 145 PSI, and closes (compressor on) when pressure drops below 110 PSI.
- Ensure the power source to the compressor system is disconnected.
- Connect the two terminals of the pressure switch into the control circuit of your air compressor system.
- For systems drawing more than a few amps, it is strongly recommended to wire the pressure switch to control a rele. The relay will then handle the high current draw of the compressor motor, protecting the pressure switch from excessive load.
- Ensure all wiring is correctly sized for the amperage in voltage of your system (up to 30 amps za 12 & 24-volt systems) and properly insulated.
- After wiring, double-check all connections for security and correct polarity before restoring power.
Delovanje
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.
Vzdrževanje
The VIAIR 90217 Pressure Switch is designed for minimal maintenance. However, periodic inspection can help ensure its continued reliability:
- Vizualni pregled: Regularly check the switch for any signs of physical damage, corrosion, or loose connections.
- Celovitost povezave: Ensure the NPT threaded connection remains tight and free of leaks. Check electrical connections for tightness and proper insulation.
- Čistoča: 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.
- Preverjanje funkcionalnosti: Periodically verify that the compressor turns on and off at the specified pressure points (110 PSI ON, 145 PSI OFF).
