2. Informació de seguretat
Always prioritize safety during installation, operation, and maintenance of the Danfoss KP-36 Pressure Switch. Failure to follow these guidelines may result in equipment damage, personal injury, or death.
- Personal qualificat: Installation and maintenance should only be performed by qualified and authorized personnel familiar with electrical and pressure systems.
- Desconnexió d'alimentació: Ensure all power supplies to the system are disconnected before commencing any installation, wiring, or maintenance work.
- Alliberament de pressió: Verify that the system pressure is fully released and isolated before connecting or disconnecting the pressure switch.
- Condicions ambientals: The switch has an International Protection Rating of IP54, indicating protection against dust ingress and splashing water. Do not expose the device to conditions beyond its specified IP rating.
- Eines adequades: Use appropriate tools for installation and adjustment to prevent damage to the switch or system components.
- Recanvis originals: Use only genuine Danfoss spare parts if replacements are necessary.
3. Configuració i instal·lació
Proper installation is crucial for the accurate and reliable operation of the KP-36 Pressure Switch.
3.1 Muntatge
The pressure switch should be mounted in a location where it is protected from excessive vibration, direct sunlight, and extreme temperatures. Ensure there is sufficient space for wiring and pressure connection.

4. Instruccions de funcionament
The Danfoss KP-36 Pressure Switch allows for adjustment of its pressure range and differential to suit specific application requirements.
4.1 Adjusting Pressure Range
The main pressure setting (cut-in or cut-out pressure) is adjusted using the large screw located on the top of the switch, typically marked "RANGE". Turn the screw clockwise to increase the set pressure and counter-clockwise to decrease it. Observe the scale visible through the window to set the desired pressure within the 10 to 60 PSI range.
4.2 Adjusting Differential
The differential (the difference between cut-in and cut-out pressure) is adjusted using a smaller screw, usually marked "DIFF". Adjusting this screw changes the pressure hysteresis. A larger differential means a wider gap between the pressure at which the switch activates and deactivates. This adjustment helps prevent rapid cycling of the connected equipment.

The switch operates in "Auto, Electric, Electrical" modes, implying its capability for automatic pressure control within an electrical circuit. The "Touch" control method likely refers to the tactile adjustment of the screws for setting the pressure parameters.
5. Manteniment
The Danfoss KP-36 Pressure Switch is designed for long-term, reliable operation with minimal maintenance. However, periodic checks can help ensure optimal performance and extend its lifespan.
- Inspecció visual: Inspeccioneu regularment l'interruptor per detectar qualsevol signe de danys físics, corrosió o connexions soltes.
- Integritat de la connexió: Check the pressure connection for leaks and the electrical wiring for fraying or loose terminals.
- Environmental Cleanliness: Keep the area around the switch clean and free from excessive dust or moisture, consistent with its IP54 rating.
- Prova funcional: Periodically verify the switch's operation by observing its cut-in and cut-out points against a known pressure source, if feasible and safe to do so.
