5.2. Schéma zapojení
The DFC15 controller connects to a flow sensor, a temperature sensor, and an optional solenoid valve. Refer to the diagram below for correct wiring:

Image: Detailed wiring diagram showing connections for the DFC15 controller, flow sensor, temperature sensor, and solenoid valve.
- Connect the flow sensor to the designated input on the controller. Ensure the flow direction matches the sensor's arrow.
- Connect the temperature sensor to its dedicated port. The M8 thread sensor should be installed in a suitable fitting in the liquid path.
- If using quantitative control, connect the 12VDC solenoid valve to the controller's output terminals. Observe polarity.
- Connect the provided 12VDC power adapter to the controller's power input.
Note: Ensure all connections are secure before applying power.
5.3. Montáž regulátoru
The controller can be mounted using the integrated eyelet on the back. Choose a location that is dry, stable, and allows for easy viewing of the display and access to buttons.

6. Návod k obsluze
6.1. Zapnutí a úvodní zobrazení
Once powered on, the DFC15 will display the current total volume, real-time flow rate, and temperature. The default units are Liters (L) and Liters Per Minute (LPM).

6.2. Setting Quantitative Control (Batch Mode)
- Stiskněte tlačítko MENU tlačítko pro vstup do nabídky nastavení.
- Navigate using the Up/Down arrows to find the "Quantitative Setting" or similar option.
- Stiskněte SOUBOR to enter the quantitative value adjustment.
- Use the Up/Down arrows to set your desired volume (e.g., 50 Liters). Press SOUBOR to confirm each digit.
- Once the value is set, press MENU pro ukončení nastavení.
- To start the quantitative dispense, press the RUN / STOP button. The controller will activate the solenoid valve and stop when the set volume is reached.
- To stop a dispense manually, press the RUN / STOP znovu tlačítko.
6.3. Adjusting K-Value (Calibration)
The K-value is a calibration factor that allows the controller to accurately measure flow from different sensors. This value may need adjustment for precise readings.
- Stiskněte tlačítko MENU tlačítko.
- Navigate to the "K-Value Setting" or "Calibration" option.
- Stiskněte SOUBOR to adjust the K-value.
- Use the Up/Down arrows to change the value. A higher K-value means the sensor is reporting more pulses per unit of volume.
- To calibrate, dispense a known volume of liquid (e.g., 10 liters) and compare it to the controller's reading. Adjust the K-value until the controller's reading matches the actual dispensed volume.
- Stiskněte SOUBOR to confirm the new K-value, then MENU vystoupit.
Tip: Start with the default K-value or a value provided with your flow sensor. Fine-tune as needed.
6.4. Changing Units (Liters/Gallons, Celsius/Fahrenheit)
The DFC15 allows you to switch between different measurement units.
- Volume/Flow Rate Units: Access the "Unit Setting" in the MENU to toggle between Liters (L) and Gallons (G) for total volume and LPM/GPM for flow rate.
- Jednotky teploty: The temperature display can be switched between Celsius (°C) and Fahrenheit (°F) via a setting in the MENU.
6.5. Resetting Total Volume
To clear the accumulated total volume, press the JASNÝ button. Confirm the reset if prompted.
7. Údržba
Regular maintenance ensures the longevity and accuracy of your DFC15 controller and associated sensors.
- Čištění: Wipe the controller's display and casinměkkým, suchým hadříkem. Nepoužívejte abrazivní čisticí prostředky ani rozpouštědla.
- Kontrola senzoru: Periodically check the flow sensor and temperature sensor for any debris, blockages, or damage. Clean as necessary according to the sensor manufacturer's instructions.
- Kontrola připojení: Ujistěte se, že všechna elektrická připojení zůstanou bezpečná a bez koroze.
- Rekalibrace: If you suspect inaccuracies or after significant changes in your system (e.g., replacing a sensor), perform a K-value recalibration as described in Section 6.3.
- Skladování: If storing the unit for an extended period, disconnect power and store in a dry, cool environment.
8. Řešení problémů
This section addresses common issues you might encounter with your DFC15 controller.
| Problém | Možná příčina | Řešení |
|---|---|---|
| Ovladač se nezapne. | Žádné napájení, vadný adaptér, uvolněné připojení. | Check power outlet. Ensure power adapter is correctly connected. Test adapter if possible. |
| Flow rate/volume display is 0 or inaccurate. | Flow sensor not connected, faulty sensor, K-value incorrect, no flow. | Verify flow sensor connection. Check for blockages in the flow path. Recalibrate K-value (Section 6.3). Ensure liquid is flowing. |
| Solenoid valve does not open/close. | Incorrect wiring, faulty valve, quantitative setting not enabled. | Check solenoid valve wiring and polarity. Ensure quantitative control is set and activated. Test valve independently if possible. |
| Temperature reading is incorrect. | Temperature sensor not connected, faulty sensor, sensor not immersed. | Verify temperature sensor connection. Ensure sensor is properly installed in the liquid. |
| Display backlight turns off too quickly. | Výchozí nastavení. | This is a power-saving feature. There may be a setting in the menu to adjust backlight timeout, consult the full user manual (PDF) if available. |
