5.2. Esquema de cablejat

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.

1. Connect the flow sensor to the designated input on the controller. Ensure the flow direction matches the sensor's arrow.
2. Connect the temperature sensor to its dedicated port. The M8 thread sensor should be installed in a suitable fitting in the liquid path.
3. If using quantitative control, connect the 12VDC solenoid valve to the controller's output terminals. Observe polarity.
4. Connect the provided 12VDC power adapter to the controller's power input.

Note: Ensure all connections are secure before applying power.

5.3. Muntatge del controlador

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. Instruccions de funcionament

6.1. Power On and Initial Display

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).

Imatge: Anglesa view of the DFC15 controller, showing the illuminated digital display with various readings.

6.2. Setting Quantitative Control (Batch Mode)

1. Premeu el botó MENÚ botó per entrar al menú de configuració.
2. Navigate using the Up/Down arrows to find the "Quantitative Setting" or similar option.
3. Premeu SET to enter the quantitative value adjustment.
4. Use the Up/Down arrows to set your desired volume (e.g., 50 Liters). Press SET to confirm each digit.
5. Once the value is set, press MENÚ per sortir de la configuració.
6. To start the quantitative dispense, press the CARRER/PARAR button. The controller will activate the solenoid valve and stop when the set volume is reached.
7. To stop a dispense manually, press the CARRER/PARAR botó de nou.

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.

1. Premeu el botó MENÚ botó.
2. Navigate to the "K-Value Setting" or "Calibration" option.
3. Premeu SET to adjust the K-value.
4. Use the Up/Down arrows to change the value. A higher K-value means the sensor is reporting more pulses per unit of volume.
5. 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.
6. Premeu SET to confirm the new K-value, then MENÚ per sortir.

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 MENÚ to toggle between Liters (L) and Gallons (G) for total volume and LPM/GPM for flow rate.
• Unitats de temperatura: The temperature display can be switched between Celsius (°C) and Fahrenheit (°F) via a setting in the MENÚ.

6.5. Resetting Total Volume

To clear the accumulated total volume, press the CLAR button. Confirm the reset if prompted.

7. Manteniment

Regular maintenance ensures the longevity and accuracy of your DFC15 controller and associated sensors.

• Neteja: Wipe the controller's display and casinNetegeu amb un drap suau i sec. Eviteu productes de neteja o dissolvents abrasius.
• Inspecció del sensor: Periodically check the flow sensor and temperature sensor for any debris, blockages, or damage. Clean as necessary according to the sensor manufacturer's instructions.
• Comprovació de la connexió: Assegureu-vos que totes les connexions elèctriques estiguin ben fixades i lliures de corrosió.
• Recalibració: 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.
• Emmagatzematge: If storing the unit for an extended period, disconnect power and store in a dry, cool environment.
