2). When "load mode" is displayed, long press to enter into the load mode setting. Press
to adjust the mode, and long press for 2s to save and exit; or else, the system will not save the
setting that was just made and automatically exit the setting interface after 12s.
10. Battery Types, Charging Voltages (Lithium Battery), Over-Discharge
Return and Over-Discharge Voltage Settings
In the non-load mode menu:
1) When is long pressed , the first interface entered is for battery type setting, and the flashing one is
the battery type currently selected. Press to select among FLD/GEL/SLD/LI.
2) After selection, short press to enter into over-discharge return and over-discharge voltage settings;
or the first to enter charging voltage setting menu for lithium battery.
3) After parameters have been set, long press for 2 s to save and exit.
parameters shall be set according to the following rule: over-discharge voltage ＜over-discharge return voltage
＜=under-voltage warning ＜floating charging voltage ＜boost charging return ＜=equalizing charging voltage ＜
overcharge voltage; and two adjacent values shall have a difference greater than 0.5 V.
11. Charging and Discharging Overload Protection and Recovery Time
In the charging and discharging overload protection mechanism, the relation between overload current and
protection time is as follows: An overload current 1.25 times of the rated current initiates a delay of 30s
before starting protection; similarly, 1.5 times, 5s and 2 times, 1s.
Overload recovery: automatic recovery after 1 minute.
12. Load Short Circuit and Recovery
