No.
Maintenance Item
Possible Fault Cause
Suggestion
1
The Run indicator
(green) blinks at 0.5
Hz.
Off: The lithium battery
has no power input or is
faulty.
1. Check the DC input of the
lithium battery.
2. Check the power cable
connection.
3. Check the fuses for the ports
on the function module and
lithium battery.
4. Check the function module
output.
5. Replace the lithium battery.
6. Check the communications
cable connection.
Blinking fast (4 Hz):
The function module
fails to communicate
with upstream
monitoring equipment.
1. Check the communications
cable connection.
2. Check whether the function
module is normal. Replace
the module if it is abnormal.

Possible Fault Cause
Suggestion
1
Check whether the
equalized charge
current limit
coefficient for lithium
batteries meets user
requirements.
-
Adjust the coefficient as
required. Retain 0.3C unless
otherwise required.
2
Check whether the
DC output voltage is
consistent with the
actual voltage
(tolerance: ±0.3 V)
and is within the
function module
The function module is
faulty.
Replace the function module.
