4. Nastavení a instalace
Follow these steps to properly set up your DIGITEN Water Flow Control System:
- Install the Flow Sensor: Integrate the G2" flow sensor into your water line. Ensure the flow direction matches the arrow indicated on the sensor body. The sensor has G2" male threads for connection.
- Connect the Flow Sensor to the Controller: The flow sensor has a cable with a connector. Plug this connector into the corresponding port on the DFC15 controller.

- Connect the Temperature Sensor (Optional): If using, connect the NTC3950 temperature sensor to its designated port on the controller. This sensor is typically used to measure the liquid temperature.
- Connect the Solenoid Valve (Optional): If you intend to use the quantitative control feature, connect your 12VDC solenoid valve to the controller's solenoid output terminals. Ensure correct polarity. The controller can output up to 5A for the solenoid valve.
- Připojte napájecí adaptér: Plug the 12VDC power adapter into the power input jack on the DFC15 controller. Then, plug the AC power adapter into a standard 100-240VAC wall outlet.

5. Návod k obsluze
The DFC15 controller features an intuitive LCD display and several control buttons:
- Tlačítko MENU: Accesses various settings and configuration options.
- Tlačítko SET: Confirms selections or enters editing mode for parameters.
- Tlačítko CLEAR: Resets values or clears current settings.
- Šipky nahoru/dolů: Navigate through menus or adjust numerical values.
- Tlačítko SPUSTIT/STOP: Initiates or halts the flow control process.
5.1. Basic Display Information
The main screen typically displays:
- Horní linie: Total accumulated volume (e.g., 0003.98 L).
- Middle Line: Real-time flow rate (e.g., 0009.60 L/min).
- Sečteno a podtrženo: Current liquid temperature (e.g., 027 °C).
- Indikátory: "RUN" and "STOP" LEDs indicate the current operational status.
5.2. Setting Quantitative Control
To set a specific volume for automatic shut-off:
- Stiskněte tlačítko MENU tlačítko pro vstup do nabídky nastavení.
- Navigate using the Up/Down arrows to find the "Quantitative Control" or "Set Volume" option.

7. Řešení problémů
If you encounter issues with your DIGITEN Water Flow Control System, refer to the following common problems and solutions:
| Problém | Možná příčina | Řešení |
|---|---|---|
| Displej je prázdný nebo se nezapíná. | Žádné napájení, vadný adaptér, uvolněné připojení. | Check power adapter connection to controller and wall outlet. Ensure outlet has power. Test adapter if possible. |
| Flow rate or total volume reading is inaccurate. | Incorrect K value, debris in flow sensor, sensor installed incorrectly. | Calibrate the K value (refer to Section 5.3). Inspect flow sensor for obstructions and ensure it's installed with correct flow direction. |
| Quantitative control does not stop flow. | Solenoid valve not connected, faulty solenoid valve, incorrect wiring. | Verify solenoid valve connection and wiring (refer to Section 4 and Figure 6). Test solenoid valve independently if possible. Ensure quantitative value is set correctly. |
| Temperature reading is incorrect or absent. | Temperature sensor not connected, faulty sensor. | Check temperature sensor connection to the controller. Ensure the sensor is properly immersed in the liquid if measuring liquid temperature. |
