Electricity imbalance
：
0006
When (maximum phase current and minimum phase current)
≥
1 + (set value / / 10 +), unbalanced protection works, the air
compressor fails to stop, and the motor is reported to be
unbalanced. Set
≥
15:00, no unbalanced protection.
Phase break protection
time
（
s
）：
002.0
When the off phase protection time is set
≥
20 seconds, the
phase off protection function is forbidden.
Historical malfunction
reset
：
0000
Enter "8888" and, after confirmation, clear the history of the
failure.
Early warning shutdown
（
h
）：
0000
Air compressor material warning, after the time set here after
the failure shutdown.
Max using time
（
h
）：
0000
The accumulative running time of the air compressor exceeds
the set value here, and when the air compressor is in the
downtime, the fault alarm shows "use error".
Manufacturer password
2:
0000
The manufacturer sets up a modifiable factory password.
Voltage too high
（
V
）：
0410
Whenthedetectionvoltageofthecontrollerishigher thantheset
value,thestopprotectionandthereported
voltage are too high.
When set to 0000, the high voltage function is invalid.
Voltage low
（
V
）：
0350
When the detection voltage of the controller is lower thantheset
value,thestopprotectionandthereported
voltage are too low.
When set to 0000, the low voltage function is invalid.
Communication timeout
（
s
）：
002.0
The timing starts when the controller sends the first byte, and if no
response from the converter is received within this time, the controller
determines thetimeout
and resends the command data.
Communication
interruption
（
s
）
:
0020
The controller failed to receive the correct data continuously
over the set time and reported the
communication interruption.
Communications
resumed:
0015
After the communication is interrupted, the correct datais
receivedcontinuouslyoverthesettimes,andthe
communication is considered to be back to normal.
Timing start and stop
function:
Open /
prohibit
Set to open: timing start and stop function is
effective.
Set to prohibit: timing start and stop function is not functional.
Timing pressure
function
Open /
prohibit
Set to open: timing pressure function is effective.
Set to prohibit: timing pressure function is not functional.
Total running time: (h)
000100h
：
00min
Modify the total operating time of the air compressor.
