2. Safety Information

Always adhere to local regulations and safety standards when installing, operating, or servicing the pressure switch. Failure to do so may result in personal injury or equipment damage.

• Installation and service must be performed by qualified personnel only.
• Disconnect power supply before performing any electrical connections or maintenance.
• Ensure the system pressure is relieved before connecting or disconnecting the pressure switch.
• Do not exceed the specified maximum operating pressure and electrical ratings.
• Protect the switch from moisture, dust, and extreme temperatures unless specifically designed for such conditions.

3. Setup and Installation

3.1. Mounting

The KP1 pressure switch can be mounted in any position. Ensure the mounting location is free from excessive vibration and provides adequate space for wiring and adjustments.

3.3. Electrical Connection

The KP1 060-1101 features screw terminals for electrical connections. Refer to the wiring diagram inside the switch cover for correct connections. Ensure all connections are secure and comply with electrical codes.

• Disconnect power before wiring.
• Connect the power supply and load to the appropriate terminals.
• The switch has a Normally Closed (NC) contact type.

3.4. Pressure Setting Adjustment

The KP1 pressure switch allows adjustment of both the cut-in/cut-out pressure (Range) and the differential pressure (Diff). These adjustments are typically made using screws located under the cover.

1. Range Adjustment: Use the screw associated with "RANGE" to set the desired cut-out pressure.
2. Differential Adjustment: Use the screw associated with "DIFF" to set the difference between the cut-in and cut-out pressures.
3. Ensure the system is depressurized before making adjustments.

4. Operating Instructions

Once installed and adjusted, the Danfoss KP1 060-1101 operates automatically based on the set pressure range. It functions as an automatic pressure controller.

• The switch will activate or deactivate connected equipment when the system pressure reaches the set cut-in or cut-out points.
• Some models may feature a manual reset button (indicated as "Reset Auto" in some diagrams). If present, this button allows for manual resetting of the switch after an alarm condition or power interruption.

5. Maintenance

The Danfoss KP1 pressure switch is designed for minimal maintenance. Regular inspection is recommended to ensure optimal performance and longevity.

• Visual Inspection: Periodically check the switch for any signs of physical damage, corrosion, or loose connections.
• Cleaning: Keep the exterior of the switch clean and free from dust and debris. Use a dry, soft cloth. Do not use abrasive cleaners or solvents.
• Functionality Check: If possible and safe to do so, periodically verify the switch's operation by observing its response to pressure changes within the system.

6. Troubleshooting

Before attempting any troubleshooting, ensure the power supply is disconnected and system pressure is relieved.

If the problem persists after attempting these solutions, contact a qualified service technician or Danfoss customer support.
