안전 정보
설치 및 작동 시 다음 안전 예방 조치를 준수하세요.
- 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, amp시대, 권tage) are compatible with your air compressor system.
- Use appropriate thread sealant on the 1/8인치 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.
제품 끝view
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.
주요 특징:
- Automatically turns air compressor on at 110 PSI 그리고 off at 145 PSI.
- 특징 1/8" Male NPT Thread 보안 연결을 위해.
- Rated for use with 12 & 24-volt systems, up to 30 amps.
- 로 설계되었습니다 밀폐형 구조 for moisture resistance.
- VIAIR recommends using this pressure switch with a relay for optimal performance and longevity.
설치 지침
설치
- 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.
배선
The pressure switch acts as a control signal for your compressor. It is a 일반적으로 오픈 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 계전기. 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 amp에라지와 볼륨tage of your system (up to 30 amps ~을 위한 12 & 24-volt systems) and properly insulated.
- After wiring, double-check all connections for security and correct polarity before restoring power.
작업
Once correctly installed and wired, the VIAIR 90217 Pressure Switch operates automatically. When the air pressure in your system drops to 110파운드, 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 145파운드. 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.
유지
The VIAIR 90217 Pressure Switch is designed for minimal maintenance. However, periodic inspection can help ensure its continued reliability:
- 시각적 검사: Regularly check the switch for any signs of physical damage, corrosion, or loose connections.
- 연결 무결성: Ensure the NPT threaded connection remains tight and free of leaks. Check electrical connections for tightness and proper insulation.
- 청결: 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.
- 기능 확인: Periodically verify that the compressor turns on and off at the specified pressure points (110 PSI ON, 145 PSI OFF).
