voltage measurement
1. Restart
2.Check the connectivity and reliability
of the power and comm. cable by
reconnection.
3. Swap the current measurement
board or BMS
4.If problem remain, contact Pylontech
service engineer.

damage error
（Bit6）
Battery cell voltage
measured at <2.0V
1. Restart
2. Swap out the RED LED module
3. Use multimeter to measure the
battery module power terminal
voltage, if is the same as the BMS
reading value, then it`s a true cell
damage. Otherwise please swap the
BMU of the module.
Comm.

hardware
BMIC error
（Bit8）
Sensor chip error
1. Restart
2. If observed a module LED is off, try to
bypass the module on both comm.
and power side and see whether rest
modules` LED could be on and green.
If so, then please change the BMU of
the bypassed module. If not, further
bypass the next LED off module and
repeat the process.
3. If problem remain, contact
Pylontech service engineer.
