3. Configuració i cablejat

The CD60L module functions as a switching relay to control charging or discharging based on user-defined voltage parameters. It is important to note that this module does not regulate voltage directly; it only connects or disconnects the power path.

3.1. Charging Mode (IN) Wiring

In charging mode, the module controls the power flow from a charger to the battery. When the battery voltage drops below the set lower limit (dn), the relay closes, allowing the charger to charge the battery. When the battery voltage reaches or exceeds the set upper limit (UP), the relay opens, stopping the charging process. The display will show "IN" and blink during active charging.

Figure 3: Charging Mode (IN) Wiring Diagram

• Connect the DC 6-60V power source (charger input) to the "VIN+ VIN-" terminals.
• Connect the battery to be charged to the "OUT+ OUT-" terminals.
• Ensure correct polarity (+ to + and - to -) for all connections.

3.2. Discharge Mode (OUT) Wiring

In discharge mode, the module controls the power flow from the battery to a connected load. When the battery voltage is greater than or equal to the set upper limit (UP), the relay closes, allowing the load to draw power. When the battery voltage drops below the set lower limit (dn), the relay opens, disconnecting the load to protect the battery from undervoltage. The display will show "OUT" and blink during active discharging.

Figure 4: Discharge Mode (OUT) Wiring Diagram

• Connect the battery to the "VIN+ VIN-" terminals.
• Connect the load to the "OUT+ OUT-" terminals.
• Ensure correct polarity (+ to + and - to -) for all connections.

Nota important:

This product is a simple voltage controller that operates via a relay to turn the output on and off. It serves only as a switching mechanism and cannot change or regulate the voltage nivell.

4.2.1. Parameters in Charging Mode (IN)

Figure 6: Charging Mode Parameter Display

• UP (Upper Voltage Limit): El voltage threshold at which the charging process will stop.
• dn (Lower Voltage Limit): El voltage threshold at which the charging process will start.
• OP (Charge Time Control): Set a non-zero value (in hours) to enable time-based charging. If set to 0, time control is disabled, and charging is solely voltagcontrolat electrònicament.
• dOP (Delay Turn-on Time): Specifies the interval (0-999 seconds) between the completion of a charge/discharge cycle and the next activation of the relay.

4.2.2. Parameters in Discharge Mode (OUT)

Figure 7: Discharge Mode Parameter Display

• UP (Upper Voltage Limit): El voltage threshold at which the discharging process will start.
• dn (Lower Voltage Limit): El voltage threshold at which the discharging process will stop (undervoltage protecció).
• OP (Discharge Time Control): Set a non-zero value (in hours) to enable time-based discharging. If set to 0, time control is disabled, and discharging is solely voltagcontrolat electrònicament.
• dOP (Delay Turn-on Time): Specifies the interval (0-999 seconds) between the completion of a charge/discharge cycle and the next activation of the relay.
• FOP (Forced Start Time): After the relay's ON condition is met, the relay is forced ON for a set duration (0-10 seconds). This function is primarily for discharge mode to prevent premature relay disconnection due to instantaneous voltage drops when a test load is initially applied.

4.3. Time Control Function (OP)

Quan el OP parameter is set to a non-zero value, the module initiates a timer when the relay activates for either charging or discharging. Upon completion of the set time, the relay automatically disconnects to conclude the process. If the timer finishes but the voltage condition (e.g., voltage dn in charging mode, or voltage > UP in discharge mode) is not met, the time control function will automatically deactivate, and "H:ER" will blink on the display, indicating an improper time parameter setting. Press any key to clear the "H:ER" message.

If time control is disabled (OP=0), the module will record the cumulative time the relay was active. This recorded charging/discharging time will blink on the display when you access the time display interface. It will reset upon exiting the time display or at the start of the next charge/discharge cycle.

4.4. Voltage Percenttage Càlcul

El vol mostrattage per centtage is calculated using the formula: Battery Voltage / (Upper Voltage - Lower Voltage).

5. Solució De Problemes

• "ERR" Display: If the system displays "ERR" after setting parameters and exiting, it indicates that the lower voltage limit (dn) has been set to be greater than or equal to the upper voltage limit (UP). This is an invalid configuration. Please review and correct your voltage settings to ensure UP is always greater than dn.
• "H:ER" Blinking: This message indicates an issue with the time parameter (OP) setting. The time control function has automatically turned off because the voltage condition was not met upon completion of the set time. Adjust your OP parameter or ensure your voltage limits are appropriate for the timed operation. Press any key to clear the "H:ER" message.
• Relay Not Activating/Deactivating as Expected:
  • Cablejat: Double-check all wiring connections for correct polarity and secure contact. Loose connections can cause intermittent operation.
  • Entrada Voltage: Comproveu que l'entrada voltage to the module is within the specified DC 6-60V operating range.
  • Configuració dels paràmetres: Ensure the current battery voltage is within the set UP/dn parameters for the selected mode (IN/OUT) to trigger the relay.
  • Parada d'emergència: Check if the emergency stop function (short press DOWN button) has been accidentally activated, which disables the relay.
• La pantalla no funciona:
  • Font d'alimentació: Confirm that the module is receiving power.
  • Retroil·luminació LCD: If the LCD backlight is set to "ON" (L-P parameter), it might have automatically turned off due to inactivity. Press any key to wake it up.
