form the inverter voltage
25
None
wiring fault
INV relay and bypass SCR
open, but output voltage is
higher than normal.
Check the input and output wires
31
None
CAN
communication
fault
When
the
parallel
communication
between
the UPSs is interrupted, the
fault
signal
will
be
displayed.
Check the parallel cables between the UPSs
are normal, and the cable between the parallel
board and the control board are normal.
41
None
over temperature
The temperature of sink is
over the protection setting.
Check if UPS is overloaded, air vents are
blocked, and ambient temperature is over
40
℃
.
After overload or block is removed, please
keep UPS cool down for 10 minutes before
turning on again.
It is not recommended to operate the UPS
under over 40°C temperature environment.
42
None
DSP
communication
Failure
When the communication
between the INV control
board and the PFC control
board is interrupted, the
fault signal will be
displayed.
43
Overload
The load is over the
settings for certain time.
Check the loads and remove some non-critical
loads.
Check whether some loads are failed.
45
None
Charger Error
The UPS detect the
charger current more than
1.5A when power on the
UPS
Check the charger HCT
46
None
Model fault
The UPS can not identify
the right model.
Check the Model Pin of the Control board is
inserted correctly
47
None
DSP and MCU
communication
Failure
When the communication
between the INV control
board and the COMM
board is interrupted, the
fault signal will be
displayed.
1, for 30K~80K old version (2016~2019) AC
EMI board, maybe the problem is 5V power
have problem. It need to replace the AC EMI
board.
2, Check if the flat cable between the INV
control board and the COMM board is
normal.
49
None
Input and output
phase sequence is
not compatible
Input and output phase
sequence different
Check the input and output cable connect
status
60
None
Inverter
over
current fault
Output voltage stable and
output current RMS is
higher than normal
Check the loads and remove some non-critical
loads. Check whether some loads are failed.
61
None
Bypass SCR short
There isn’t signal drive the
bypass SCR close, but
bypass output voltage
higher
Check the wire connection make sure the
output is not source, check the Bypass SCR
circuited
62
None
Bypass SCR open
There is signal drive the
bypass SCR close, but
bypass output voltage is
lower than normal
Check Bypass SCR circuited and the input
relay circuited
