Parameter Settings
* Press and hold the SET button to enter the parameter setting interface, the LCD will display SET;
* After entering the parameter setting interface, switch the set parameters by short pressing the SET button;
* After selecting the parameters, you can use the UP/DOWN button to set, support short press, long press (rapid increase or
decrease);
* If you want to set other parameters, repeat steps b), c);

Function Description
1. Automatic charging control function:
By setting the upper limit voltage UP and the lower limit voltage dn; when the battery voltage ≤ the lower limit voltage dn, the
relay is turned on, the charger starts to charge the battery; when the battery voltage ≥ the upper limit voltage UP, the relay is
turned off, and an automatic charging is completed;
2. Charging time control function:
How to turn on time control?
After entering the parameter setting, if the setting parameter OP is not 0, the time control function is enabled. The default
parameter of the OP is: -----h, the time control function is not enabled by default;
After the time control function is turned on (OP is not 0), when the battery voltage < lower limit voltage dn, the charger starts
to charge the battery, and the system starts timing; during the timing, the battery voltage ≥ the upper limit voltage UP, the
relay is turned off; if the battery voltage
Note: Time format: 00:59 (00 for hours, 59 for minutes) The maximum time is 99:59, which is 100 hours.
3. Serial data upload and parameter setting function:
The system supports UART data upload and parameter setting functions (TTL level);
UART: 115200, 8, 1
Data upload message format:
Battery voltage + battery percentage + charging time + charging status
12.0V, 020%, 00:10, OP
Button Function Description
* In the running interface (main interface),
* Short press the SET button to display the currently set parameters;
* Short press the UP button to switch between display charging percentage and charging time;
* Press the DOWN button shortly to select the enable/disable relay enable. If the relay is enabled to turn off, ‘OFF’ will be
displayed to remind you that the relay is off.
* Press and hold the UP button to set the status of the LCD backlight (L-P), OFF: the backlight is always on, on: the backlight
is automatically turned off after 5-10 minutes;
* Press and hold the SET button to enter the parameter settings.
Additional Features
* Charging time recording function: When the charging time control is not turned on, the product will record a complete time.
When entering the time display interface, the charging time will flash; when exiting the time display interface or the next
charging is turned on (the relay is turned on), it will be cleared;
* Automatic parameter detection: When the parameter is set, when exiting, if the voltage lower limit dn ≥ upper limit voltage up,
the system will flash “ERR” to indicate the alarm;
* Battery access detection: This product is attached to the battery. If the battery is not connected, the system will display
“nbE” on the lower line to remind you;
