- Description of buzzer action
Fault: Every second, Buzzer works 0.25S;
Protection: Every 2 seconds, Buzzer works 0.25S;(except over voltage protection) Alarm: Every 3 seconds, Buzzer works 0.25S;(except over voltage protection)
The buzzer function can be enabled or disabled by the host computer, and the factory default is disabled.- Buttons Description
When the BMS is in the sleep state, press the button (3~6S) and release, the protection board is activated, and the LED indicator lights up in sequence from "RUN" for 0.5 seconds.
When the BMS is activated, press the button (3~6S) and release it, the protection board is dormant, and the LED indicator lights up in order from the lowest battery light for 0.5 seconds.
When the BMS is in the activated state, press the button (6~10S) and release it, the protection board is reset, and the LED lights are all lit simultaneously for 1.5 seconds.
After the BMS is reset, the parameters and functions set by the host computer are retained. If you need to restore the initial parameters, you can use the "restore default value" of the host computer to achieve, but the related operating records and stored data remain unchanged (such as power, cycle number, Record protection, etc.)- Sleep and wake up status
- Sleep status
When any of the following conditions are met, the system enters a low‐power mode:- The single or overall over‐discharge protection has not been released within 60 seconds.
- Press the button (3~6S) and release it.
- The lowest monomer voltage is lower than the sleep voltage, and the duration reaches the sleep delay time (at the same
time, no communication, no protection, no balance, no current).- Standby time exceeds 24 hours (no communication, no charge and discharge, no commercial power).
- Forced shutdown by the host computer software. Before entering sleep, make sure that the input terminal is not connected to an external voltage, otherwise it will not be able to enter the low power consumption mode.
- Wake up status
When the system is in low‐power mode and meets any of the following conditions, the system will exit low‐power mode and enter normal operation mode:- Connect the charger, and the charger output voltage must be greater than 48V.
- Press the button (3~6S) and release it.
- RS232 communication is activated (this method cannot wake up the motherboard due to over‐discharge).
Remarks: After single or total over‐discharge protection enters low power consumption mode, it wakes up regularly every 4 hours and turns on charge and discharge MOS. If it can be charged, it will exit the sleep state and enter normal charging; if it can not be charged after 10 consecutive automatic wakeups, it will no longer automatically wake up.
When the system is defined as the end of charging, the recovery voltage has not been reached after 2 days of standby (standby time setting value), and the charging is forced to resume until the end of recharging. - Appearance
