1. Киришүү

This manual provides essential information for the safe and effective installation, operation, and maintenance of the Danfoss KP 35 Low Current Pressure Switch. The KP 35 is designed for use in various applications including refrigeration, air conditioning, and general industrial systems, monitoring and controlling pressure within a specified range.

2. Коопсуздук маалыматы

ЭСКЕРТҮҮ: Improper installation, operation, or maintenance can result in serious injury or equipment damage. Always follow these safety guidelines:

• Ensure power supply is disconnected before installation or servicing.
• Орнотуу жана тейлөө квалификациялуу кызматкерлер тарабынан гана аткарылышы керек.
• Verify that the pressure switch specifications match the system requirements.
• Do not exceed the maximum rated pressure or temperature.
• Protect the switch from physical damage and environmental extremes.

3. Продукт бүтүп калдыview

The Danfoss KP 35 pressure switch is a compact, robust control device featuring a single-pole double-throw (SPDT) contact system. It is designed for regulating, monitoring, and alarm systems in industrial applications. The switch is equipped with a pressure connection and electrical terminals for easy integration into control circuits.

5. Орнотуу

5.1 Монтаждоо

1. Select a suitable location free from excessive vibration, moisture, and extreme temperatures.
2. Mount the switch using the provided mounting holes. Ensure it is securely fastened.
3. The switch can be mounted in any position, but vertical mounting with the pressure connection downwards is generally recommended to prevent accumulation of liquids in the pressure connection.

5.2 Pressure Connection

1. Connect the pressure switch to the system's pressure line using the 1/2 inch connection.
2. Use appropriate sealing material (e.g., PTFE tape) to ensure a leak-free connection.
3. Avoid overtightening the connection to prevent damage to the switch or piping.

5.3 Электр зымдары

ЭСКЕРТҮҮ: Disconnect all power before performing electrical wiring.

1. Remove the cover of the switch to access the electrical terminals.
2. Connect the electrical wires according to the system's wiring diagram and local electrical codes. The KP 35 features SPDT contacts.
3. Бардык байланыштар коопсуз жана туура изоляцияланганын текшериңиз.
4. Replace the cover securely after wiring.

6. Орнотуу жана тууралоо

The KP 35 pressure switch allows for independent adjustment of the cut-in pressure (range) and the differential pressure.

1. Adjusting the Range (Cut-in Pressure): Use the larger adjustment screw or knob (typically marked "RANGE") to set the desired cut-in pressure. This is the pressure at which the switch will activate or deactivate.
2. Adjusting the Differential: Use the smaller adjustment screw or knob (typically marked "DIFF") to set the differential pressure. This is the difference between the cut-in and cut-out pressures. For example, if the range is set to 5 bar and the differential to 1 bar, the switch will cut in at 5 bar and cut out at 4 bar (for a decreasing pressure application).
3. Refer to the scales on the front of the switch for precise settings.
4. After adjustment, verify the settings by observing the system's pressure and the switch's operation.

7. Иштөө нускамалары

Once installed and adjusted, the Danfoss KP 35 pressure switch operates automatically based on the system pressure. When the pressure reaches the set cut-in point, the SPDT contacts will switch position. When the pressure changes by the set differential, the contacts will switch back.

• Monitor system pressure to ensure it remains within the safe operating limits of both the switch and the overall system.
• Observe the electrical load connected to the switch to ensure it does not exceed the switch's rated capacity.

8. Техникалык тейлөө

The Danfoss KP 35 pressure switch is designed for long-term, reliable operation with minimal maintenance. However, periodic checks are recommended:

• Визуалдык текшерүү: Өчүргүчтү физикалык бузулуулардын, дат басуулардын же бош туташуулардын белгилерин үзгүлтүксүз текшерип туруңуз.
• агып текшерүүлөр: Periodically check the pressure connection for any leaks.
• Функционалдык тест: If possible and safe, periodically test the switch's operation by simulating pressure changes to ensure it activates and deactivates at the set points.
• Тазалоо: Keep the exterior of the switch clean and free from dust and debris. Do not use harsh chemicals.

9. Кыйынчылыктарды

If the pressure switch is not functioning as expected, consider the following common issues:
