Switch. The Status LED shows
normal. But can't output
power.
Turn on and turn off the
"POWER OUTPUT" Switch, it
without clear mechanic
switching sound inside of
BMS.
6 Turn on the BMS. The Status
LED is flashing red.
7 Turn on the BMS. The Status
LED is lighting red. And the
buzzer is noising.
8 Turn on the BMS. The Status
LED shows normal. But the
output relay can't be
actuation.
9 Turn on the BMS. The one
and the following of the
battery module's Status LED
lighting red or not lighting.
10 Single Cell is over voltage/
low voltage.
(Check through the monitor
or maintenance software.)
11 Battery module shows the
temperature is -40℃.
(Check through the monitor
or maintenance software.)
12 Another failure
breaker is fault.
Self-check can't pass.
 Output relay is

operation for breaker is fault
or not. If it is fault, change
the control module (BMS
module).
If something is wrong, please
contact with seller or sells
agent.
 Check the output relay. If
fault find out the short
circuit reason. Change
the relay or the control
module (BMS module).
 Change the control
module (BMS module).
Check the wire of output
relay got loose or broken? Fix
it. Or change the control
module (BMS module).
 Change this battery
module;
 Check the
communication cable;
 Check by professional
stuff.
 Check the wires of cell
sampling module;
 Change this battery
module.
Check the wires of
temperature sampling
module. Or change this
battery module.
Can't find out failure point or
can't check. Please contact
with seller or sells agent.
