6. මෙහෙයුම

The digital pressure switch allows for precise control and monitoring of pressure levels. The device typically features buttons for setting parameters and navigating menus.

6.1 මූලික මෙහෙයුම

Upon powering on, the display will show the current pressure reading. Use the 'Up' and 'Down' buttons (often labeled with arrows) to navigate through settings and adjust values. The 'S' button is typically used to enter menus, confirm selections, or save settings.

• Setting Pressure Thresholds: Access the setting menu to define the desired ON/OFF pressure points. The minimum setting unit is 0.1kPa.
• Adjusting Response Time: The device includes an anti-vibration function and allows adjustment of the response time. This helps prevent false triggers due to rapid, momentary pressure fluctuations. Consult the physical manual for specific steps to adjust this parameter.
• නිමැවුම් තත්වය: The PNP open collector output will activate when the pressure conditions meet the set thresholds. Some models may indicate output status via a change in display color (e.g., red to green).

6.2 පිටපත් කිරීමේ කාර්යය

A unique feature of this digital pressure switch is its copy function, which allows for efficient configuration of multiple units:

• When the pressure switch is powered on, the set values from a main sensor can be copied to up to 10 side sensors simultaneously.
• The minimum transmission distance for this function is 4 meters.
• This copy function requires the use of a dedicated communication line (not included with the standard package, refer to accessories).

7. දෝශ නිරාකරණය

If you encounter issues with your GOWENIC Digital Air Pressure Switch, consider the following troubleshooting steps:

• බලය නැත/සංදර්ශකය අක්‍රියයි: Check the DC 12-24V power supply connection. Ensure correct polarity and that the power source is active.
• වැරදි කියවීම්: Verify that the pressure switch is properly connected to the system and that there are no leaks at the RC 1/8in thread. Ensure the fluid being measured is compatible (non-corrosive, non-flammable gas).
• ප්‍රතිදානය සක්‍රිය නොවේ: Confirm that the set pressure thresholds are correctly configured. Check the wiring of the PNP open collector output to your control circuit. Ensure the load current does not exceed 80mA.
• Confusing Controls: The controls for setting ON/OFF points can sometimes be counter-intuitive. If you set the values incorrectly, try reversing the high and low settings. Refer to the detailed instructions in the physical user manual for specific programming sequences.
• Rapid Pressure Changes Causing Maloperation: Adjust the response time setting to a longer duration to filter out rapid, transient pressure fluctuations.

If the problem persists after attempting these steps, contact customer support for further assistance.
