Button function

• UP button: short press to switch the display % and time, long press for 5 seconds to switch the mode, charging mode: IN, discharge mode: OUT.
• SET button: short press to view the currently set parameters; long press the SET button to enter the parameter setting interface, set UP: voltage upper limit, dn: voltage lower limit, OP: conduction time, dOP: delayed conduction time (0-999 seconds), FOP: forced conduction time (0-10 seconds) in discharge mode.
• DOWN button: short press to turn off/on the relay enable (emergency stop function) after turning off, the LCD displays OFF and the relay is disconnected. Long press the DOWN button to set the LCD backlight status L-P: OFF backlight is always on, ON: the backlight automatically turns off after 5-10 minutes; after turning off, press any button to wake up.

Parameter Settings

• A) Enter the parameter setting interface by pressing the SET key for a long time;
• B) After entering the parameter setting interface, switch the setting parameters by pressing the SET key;
• C) After choosing parameters, it can be set by UP/DOWN key to support short press and long press;
• D) To set other parameters, repeat steps B and C;
• E) After all parameters are set, press SET key for a long time, exit and save.

1. Charging/Discharging Time Control Function

When the time parameter OP is non-zero, start charging/discharging time control.

When the relay turns on a charge/discharge, the countdown begins; when the time is completed, the relay is automatically disconnected to complete a charge/discharge process; if the time is completed, in the charging mode, the detection voltage is less than the lower limit voltage dn or in the discharge mode, the detection voltage is more than the upper limit voltage UP, and the charging time control function is automatically turned off and flashes. Indicate H: ER reminds users that time parameter setting is unreasonable; press any key to stop flickering;

When the charging/discharging time control is not turned on, the product will record a complete time. When entering the time display interface, flashing shows the charging time, then exiting the time display interface or clearing the next time the charging is turned on (relay is turned on).

2. Automatic parameter detection:

When the parameters are set and exit, if the lower voltage limit DN is greater than the upper voltage up, the system will flicker to display "ERR" as a reminder.

3. Delayed turn-on function (0-999 seconds): completion of a charge/discharge, the interval between re-opening;

4. Discharge Conduction Forced Start Time (0-10S): After satisfying the relay conduction condition, the relay is forced to turn on (0-10S) to detect the battery voltage again. This function is mainly aimed at discharging function. Some test loads will pull down the lower limit voltage instantaneously at the moment of conduction, which will lead to the disconnection of the relay and the failure of normal discharge process.
