4. Configuració i instal·lació

Proper installation is crucial for accurate readings and safe operation. The monitor supports two main wiring methods:

4.1 Hall Sensor Installation

The Hall sensor measures current by detecting the magnetic field around the wire. Ensure the wire carrying the current to be measured passes through the center of the Hall sensor. The triangle icon on the sensor should point in the direction of the load when measuring the positive lead.

4.2 Two-Wire Connection (5-90V)

This method is suitable for monitoring systems where the power supply for the meter is within the 5-90V range and is the same as the circuit being measured.

1. Connecteu el fil vermell of the meter to the positive terminal of the battery.
2. Connecteu el filferro negre of the meter to the negative terminal of the battery.
3. Connecteu el filferro groc of the meter to the positive terminal of the battery.
4. Pass the positive lead from the battery to the load/controller through the Hall sensor. Ensure the triangle icon on the sensor points towards the load.

4.3 Three-Wire Connection (0-300V)

This method is used when the meter's power supply is separate from the circuit being measured, or when monitoring voltages outside the 5-90V range (up to 300V).

1. Connecteu el fil vermell of the meter to a separate DC 5-100V power supply's positive terminal.
2. Connecteu el filferro negre of the meter to the negative terminal of the battery (common ground).
3. Connecteu el filferro groc of the meter to the positive terminal of the battery being monitored.
4. Pass the positive lead from the battery to the load/controller through the Hall sensor. Ensure the triangle icon on the sensor points towards the load.

5. Instruccions de funcionament

5.1 Disseny de la pantalla

The STN LCD display provides clear readings of various parameters. Refer to the image below for an explanation of each display area:

Imatge: Detallada view of the DROK Battery Monitor's LCD display, indicating the location of remaining capacity (AH and percentage), current, voltage, power, and accumulated energy readings, along with button labels.

• Battery Bar: Indicates the remaining capacity of the battery visually.
• AH Display: Shows the remaining Amp-hours of the battery.
• Corrent (A): Displays the DC current in Amperes. Positive values indicate current flowing out (discharge), negative values indicate current flowing in (charge).
• Voltage (V): Mostra el volum de DCtage en Volts.
• Potència (W): Displays the instantaneous power in Watts. Positive for discharge, negative for charge.
• Accumulated Energy (WH): Shows the total accumulated electric energy in Watt-hours.
• Menu/Save Key: Used to enter menu settings and save changes.
• Backlight/+ Key: Used to control the backlight and navigate menu options.

5.2 Basic Operation and Settings

The monitor has several configurable parameters to ensure accurate readings for your specific battery system.

1. Entrant al mode de configuració: Press and hold the "Menu/Save key" for approximately 3 seconds to enter the setup menu.
2. Navigating Parameters: Use the "Backlight/+ Key" to cycle through the available parameters.
3. Ajust de valors: While a parameter is selected, press the "Menu/Save key" to enter edit mode, then use the "Backlight/+ Key" to adjust the value. Press "Menu/Save key" again to confirm the value.
4. Desar la configuració: After making all desired changes, press and hold the "Menu/Save key" for approximately 4 seconds until the display flashes, indicating settings have been saved.

5.3 Key Parameters to Set

• AH (Amp-Hour Capacity): Estableix això al total Amp-hour capacity of your battery bank. For example, for a 100Ah battery, set to 100.0.
• FU (Full Voltage): Set this to the voltage at which your battery is considered fully charged. This helps the monitor accurately determine 100% capacity.
• HU (High Voltage Alarma): Set the upper voltage limit. The monitor will alarm if the voltage supera aquest valor.
• LU (Low Voltage Alarma): Set the lower voltage limit. The monitor will alarm if the voltage baixa per sota d'aquest valor.
• HA (High Amp Alarma): Set the upper current limit. The monitor will alarm if the current exceeds this value.

Note: Some versions may display additional parameters like CU, AA, AU. These are typically for advanced features (e.g., Bluetooth versions) and can generally be ignored or left at default values (000.0) if not applicable to your model.

5.4 Current Calibration (Zeroing)

To ensure accurate current readings, especially after initial setup or if readings appear incorrect:

1. Ensure the battery is fully charged and no electrical loads are connected or drawing power.
2. In standard display mode (not setup mode), press the "Backlight/+ Key" (often labeled as the '+' key) for approximately 2 seconds.
3. The display should show 0.00A, indicating successful calibration. This sets the zero point for current measurement.

Control de retroiluminació 5.5

A short press of the "Backlight/+ Key" will toggle the display backlight ON or OFF.

7. Solució De Problemes

If you encounter issues with your DROK WLS-PVA200 Battery Monitor, consider the following common problems and solutions:

• Pantalla en blanc:
  • Check all wiring connections, especially the red and black power wires, to ensure they are secure and correctly connected to a power source within the specified voltage gamma.
  • Verifiqueu que la font d'alimentació estigui activa i que proporcioni el volum correctetage.
• Inaccurate Current Readings:
  • Perform a current calibration (zeroing) as described in Section 5.4. Ensure no current is flowing through the Hall sensor during calibration.
  • Check the direction of the Hall sensor. The triangle icon should point towards the load for positive discharge readings. Reverse the sensor if charging current is not displayed as negative.
  • Ensure only one wire (the positive lead) passes through the Hall sensor.
• Incorrect Capacity (AH) or Battery Percentage:
  • Verify that the AH (Amp-Hour Capacity) parameter is correctly set in the menu to match your battery bank's capacity (Section 5.3).
  • Ensure the FU (Full Voltage) parameter is accurately set to your battery's fully charged voltage. The device uses this to determine 100% charge.
  • If the battery indicator is flashing empty after charging, recalibrate the current to zero when the battery is full and no load is present.
• Alarm Function Not Working or False Alarms:
  • Check the HU (High Voltage), LU (Low Voltage), and HA (High Amp) alarm parameters in the setup menu (Section 5.3) to ensure they are set to appropriate values for your system.
• Difficulty with Menu Navigation/Settings:
  • Refer to Section 5.2 for detailed instructions on entering setup mode, navigating, adjusting, and saving parameters.
  • Remember to press and hold the "Menu/Save key" for 4 seconds to save changes.
