5. Орнотуу жана орнотуу
Proper installation is crucial for the accurate and reliable operation of your DIGITEN Water Flow Control System. Follow these steps carefully:
Figure 5.1: Wiring diagram illustrating the connections between the controller, flow sensor, solenoid valve, temperature sensor, and power adapter.
- Контроллерди орнотуу: Choose a suitable location for the DFC15 controller that is easily accessible and protected from direct water exposure.
- Install the Flow Sensor: Integrate the G1/2" flow sensor into your water line. Ensure the flow direction matches the arrow indicated on the sensor body. Use appropriate sealing tape (e.g., Teflon tape) on all threaded connections to prevent leaks.
- Install the Solenoid Valve: Install the G1/2" solenoid valve in the water line, typically downstream of the flow sensor. Pay attention to the flow direction arrow on the valve. Ensure secure and leak-free connections.
- Connect the Flow Sensor to Controller: Connect the flow sensor's signal cable to the designated input on the DFC15 controller. Refer to the wiring diagram (Figure 5.1) for correct pin assignments (VCC, GND, Signal).
- Connect the Solenoid Valve to Controller: Connect the solenoid valve's power wires to the controller's solenoid output terminals. Ensure correct polarity if specified.
- Connect the Temperature Sensor: If using, connect the temperature sensor to its dedicated input on the controller.
- Туташуу кубаты: Plug the 12VDC power adapter into a standard AC outlet (100-240VAC) and connect its output plug to the DFC15 controller's power input.
- Байланыштарды текшерүү: Before applying water pressure, double-check all connections for tightness and correct wiring.
Note on Sealing: Some users have reported that the 1/2" connections may require a generous amount of Teflon tape to ensure a watertight seal, especially under pressure. Apply tape thoroughly to all male threads.
6. Иштөө нускамалары
The DFC15 controller features an intuitive LCD display and control buttons for easy operation.

6.1 Негизги операция
- Күйгүзүү: Электр кубатына туташтырылгандан кийин, LCD дисплей күйөт.
- Маалыматты көрсөтүү: The main screen displays the total volume, real-time flow rate (LPM/GPM), and sensed temperature (°C/°F).
- RUN/STOP Button: басыңыз RUN/STOP button to initiate or halt the flow. When running, the solenoid valve will open, allowing liquid to pass.
- Setting Quantitative Flow:
- басыңыз SET button to enter the quantitative setting mode.
- колдонуу UP жана ылдый arrows to adjust the desired volume.
- Басыңыз SET маанисин ырастоо үчүн кайрадан басыңыз.
- Басыңыз RUN/STOP to start the flow. The system will automatically stop when the set volume is reached.
- Clearing Total Volume: басыңыз CLEAR button to reset the accumulated total volume.
6.2 Advanced Settings (K Value Calibration)
The K value is a calibration factor that allows the controller to accurately measure flow with different sensors. It may need adjustment for optimal accuracy.
- Access K Value Setting: басыңыз МЕНЮ button to navigate through settings until you find the K value adjustment.
- Adjust K Value: колдонуу UP жана ылдый arrows to change the K value. A higher K value means the sensor is reporting more pulses per unit of volume, and vice-versa.
- Калибрлөө процедурасы:
- Measure a known volume of liquid (e.g., 1 liter or 1 gallon) using a precise measuring container.
- Run the system to dispense this known volume.
- Compare the dispensed volume with the volume displayed on the controller.
- Adjust the K value incrementally until the displayed volume matches the actual dispensed volume. For example, if the controller reads lower than actual, decrease the K value. If it reads higher, increase the K value.
- Жөндөөлөрдү сактоо: Басыңыз SET or МЕНЮ (depending on the specific firmware) to save the new K value.
Note on Button Responsiveness: Some users have noted that the controller may require two presses of the RUN/STOP button to initiate operation if it has entered a sleep mode. The first press wakes the unit, and the second initiates the flow.
