5. Installation
The GOWENIC Digital Air Pressure Switch is designed for straightforward installation. Follow these steps for proper setup:
- Montage: Securely mount the digital pressure switch in the desired location. Ensure it is easily accessible for viewing the display and operating the buttons.
- Thread-Verbindung: Connect the RC 1/8in thread of the pressure switch to your pneumatic or vacuum system. Use appropriate sealing tape or compound to ensure an airtight connection. Avoid overtightening to prevent damage to the thread or the device.
- Elektrischer Anschluss: Connect the provided connecting cable to the pressure switch and to your DC 12-24V power supply and control circuit. Refer to the wiring diagram (if provided in the physical manual) for correct polarity and output connections. The switch features a PNP open collector output.
- Einschalten: Once all connections are secure, apply power to the device. The digital display should illuminate.

6. Bedienung
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 Grundlegende Bedienung
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.
- Ausgabestatus: 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 Kopierfunktion
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. Fehlerbehebung
If you encounter issues with your GOWENIC Digital Air Pressure Switch, consider the following troubleshooting steps:
- Kein Strom/Display aus: Check the DC 12-24V power supply connection. Ensure correct polarity and that the power source is active.
- Falsche Messwerte: 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).
- Ausgabe wird nicht aktiviert: 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.
Sollte das Problem nach Durchführung dieser Schritte weiterhin bestehen, wenden Sie sich bitte an den Kundendienst, um weitere Unterstützung zu erhalten.
