2. Safety Information

Please read and understand all safety instructions before installing, operating, or maintaining this device. Failure to follow these instructions may result in property damage, injury, or death.

• Electrical Safety: Ensure all power is disconnected before wiring or servicing the device. All electrical connections must comply with local and national electrical codes.
• Pressure Safety: Always depressurize the system before installing or removing the pressure switch. Use appropriate personal protective equipment (PPE) when working with pressurized systems.
• Qualified Personnel: Installation and maintenance should only be performed by qualified and trained personnel.
• Environmental Conditions: Do not expose the device to conditions outside its specified operating range (temperature, humidity, pressure).
• Intended Use: Use this device only for its intended purpose as a pressure switch relay controller.

3. Setup and Installation

The HNS-206 is designed for straightforward installation. Follow these steps to ensure proper setup:

1. Preparation:
   • Ensure the system is depressurized and power is disconnected.
   • Gather necessary tools (e.g., wrenches, wire strippers, screwdriver).
2. Mounting:
   • Select a suitable location for mounting the pressure switch, ensuring it is easily accessible for adjustments and maintenance.
   • The device can be directly connected to the pipeline. Ensure a secure, leak-free connection using appropriate thread sealant if necessary.
3. Electrical Wiring:
   • Refer to the wiring diagram provided with your specific unit (not included in this general manual) for correct electrical connections.
   • Connect the power supply and load according to the diagram. Ensure all connections are tight and insulated.
4. Initial Pressure Setting:
   • Before applying pressure, set the desired pressure range using the adjustment mechanism on the device. The visible scale indicates pressure in bar and psig.
   • Consult the product specifications for the adjustable pressure range of your specific HNS-206 model.

4. Operating Instructions

Once installed and wired, the Bolisila HNS-206 operates automatically to control liquid pressure. Follow these guidelines for operation:

1. Power On: Restore power to the system. The pressure switch will begin monitoring the liquid pressure.
2. Pressure Monitoring: The device continuously monitors the pressure within the connected pipeline.
3. Relay Activation: When the liquid pressure reaches the set upper limit, the internal relay will activate (or deactivate, depending on configuration) to control the connected equipment (e.g., pump, valve).
4. Pressure Differential: The switch typically operates with a pressure differential (hysteresis) to prevent rapid cycling. The relay will remain in its activated/deactivated state until the pressure crosses the lower limit.
5. Adjusting Set Points: If pressure set points need adjustment, ensure the system is depressurized and power is off before making changes to the adjustment mechanism.

5. Maintenance

Regular maintenance ensures the longevity and reliable operation of your Bolisila HNS-206 Pressure Switch Relay Controller.

• Periodic Inspection: Visually inspect the device and its connections regularly for any signs of wear, damage, or leaks.
• Cleaning: Keep the exterior of the device clean and free from dust and debris. Do not use abrasive cleaners or solvents.
• Connection Integrity: Periodically check all electrical and pressure connections to ensure they remain tight and secure.
• Calibration Check: If precise pressure control is critical, consider periodic calibration checks by a qualified technician to ensure accuracy.
• Replacement: If the device shows signs of malfunction or significant wear, replace it with an original Bolisila HNS-206 or equivalent model.
