2. Коопсуздук маалыматы
ЭСКЕРТҮҮ: Read and understand all instructions before installing, operating, or servicing this device. Failure to follow these instructions may result in death, serious injury, or equipment damage.
- Disconnect all power before working on the switch or connected equipment.
- Орнотуу жана тейлөө квалификациялуу кызматкерлер тарабынан гана аткарылышы керек.
- Ensure the pressure system is depressurized before connecting or disconnecting the pressure switch.
- Verify that the operating pressure range of the system does not exceed the switch's specified limits (40 psi to 170 psi).
- Protect the switch from environmental conditions beyond its IP54 rating.
3. Орнотуу жана орнотуу
3.1 Монтаждоо
Mount the pressure switch in a location free from excessive vibration, moisture, and extreme temperatures. Ensure adequate space for wiring and pressure line connections. The switch is designed for flange mounting.
3.2 Басым менен туташуу
- Ensure the pressure system is completely depressurized.
- Connect the pressure line to the 1/4" NPSF flange port on the switch.
- Use appropriate thread sealant to ensure a leak-free connection. Do not overtighten.
3.3 Электр зымдары
The 9013GHG2J30 is a Double Pole Single Throw Normally Closed (DPST-NC) switch. This means that under normal (low pressure) conditions, the contacts are closed, and they open when the pressure rises above the set point.
- Disconnect all power to the circuit before wiring.
- Open the switch enclosure.
- Connect the electrical wires to the screw terminals as per your system's wiring diagram. Refer to local electrical codes.
- Бардык байланыштар коопсуз жана туура изоляцияланганын текшериңиз.
- Close the switch enclosure securely to maintain its IP54 rating.
3.4 Басымды жөндөө
The switch has an adjustable operating range between 40 psi and 170 psi. The exact adjustment mechanism (e.g., screw, knob) is typically located inside the enclosure. Consult the specific product diagram for precise adjustment instructions.
- Depressurize the system and disconnect power.
- Open the switch enclosure.
- Locate the adjustment screw/mechanism.
- Turn the adjustment mechanism to set the desired pressure actuation point within the 40-170 psi range. Turning clockwise typically increases the set point.
- Close the enclosure, repressurize the system, and restore power to test the setting. Repeat adjustment if necessary.
4. Иштөө нускамалары
Once properly installed and adjusted, the Schneider Electric 9013GHG2J30 Pressure Switch operates automatically. When the system pressure falls below the set point, the DPST-NC contacts will close, completing the circuit. When the system pressure rises above the set point, the contacts will open, interrupting the circuit.
- Ensure the system pressure remains within the operational limits of the switch.
- Regularly monitor the system to confirm the switch is actuating at the desired pressure points.
5. Техникалык тейлөө
The 9013GHG2J30 Pressure Switch is designed for reliable operation with minimal maintenance. However, periodic inspection is recommended to ensure optimal performance and longevity.
- Визуалдык текшерүү: Periodically check the switch for any signs of physical damage, corrosion, or loose connections.
- Агып кетүүнү текшерүү: Inspect the pressure connection for any signs of leaks. Tighten if necessary, ensuring not to overtighten.
- Функционалдык тест: If possible and safe, periodically test the switch's actuation point to ensure it is operating within the desired pressure range.
- Тазалоо: Keep the exterior of the switch clean and free from dust and debris. Use a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
ЭСКЕРТҮҮ: Always disconnect power and depressurize the system before performing any maintenance.

| Көйгөй | Мүмкүн себеп | Чечим |
|---|---|---|
| Switch does not actuate at set pressure. | Туура эмес басым орнотуу. Blocked pressure port. Туура эмес зымдар. Internal switch failure. | Verify and adjust the pressure setting. Check for obstructions in the pressure line/port. Зымдардын бош туташууларын же бузулууларын текшериңиз. Эгерде баары жардам бербесе, которгучту алмаштыруу керек болушу мүмкүн. |
| Pressure leaks at connection. | Improperly sealed connection. Бузулган жиптер. | Depressurize, disconnect, reapply thread sealant, and reconnect. Inspect threads for damage; replace components if necessary. |
| Electrical circuit remains open/closed unexpectedly. | Туура эмес зым. Internal contact welding/failure. Pressure outside operating range. | Review зымдардын схемасы жана туура туташуулар. Test switch continuity; replace if contacts are faulty. Ensure system pressure is within 40-170 psi. |
