c)
The STOP button will NOT stop an Inverter while drawing power and will NOT stop charging if there is
current from the Charger. Loads & Charger must be OFF to allow the BMS to enter into Sleep Mode.

BMS Relay controller output current at 12V when Chargery Mechanical Relay closed.
a)
12V 100A relay, coil current is 0.75A at 12V drive voltage.
b)
12V 200A relay, coil current is 0.96A at 12V drive voltage.
c)
12V 400A relay, coil current is 1.24A at 12V drive voltage.
d)
12V 600A relay, coil current is 1.3A at 12V drive voltage.
Because the relay coil current is far more than BMS working current, to avoid any cell being over
discharged, please operate as below,
a)
if the battery is not in use (exclude charging), please disconnect coil driven wire.
b)
If storage for over 1 month, please press STOP button place the BMS into Sleep Mode.
c)
If storage for over 3 months, please turn off the BMS directly. You may use the External / Internal
power switch if using internal power.
10.
Show timeout during updating,
a)
Download the correct firmware according to product model and save to your PC, from
http://chargery.com/update.asp
b)
Update tool software version must be v1.03 or greater. Always use the most current.
c)
Connect BMS main unit or LCD unit to the PC by using the provided USB cable.
d)
Turn on BMS main unit.
e)
Execute update tool software and lock the com port by click OPEN button.
f)
Click open file button and upload the correct firmware.
g)
Click update button finish update.
11.
Charging stops, the possible reasons are as below.
a)
Any cell voltage reaches “Over Charge Protection(P) Voltage“ setting.
b)
The highest cell voltage is over “Over Charge Release(R) Voltage” setting.
c)
Charging current is over “Over charge current” setting.
