Press
▲ or ▼ to select the parameter you need, and press ◄ or ► to select the parameter value, then press the
ENT key to confirm. The value description of the DC parameters is listed in Table 4-13.

The DC OverVolt alarm w ill be generated w hen the system
DC voltage is higher than the setting value
The values of
these three
parameters
should be:
Over Volt >
Low Volt 1 >
Low Volt 2
Low Volt 1
45.0V
The DC Low Volt1 alarm w ill be generated w hen the system
DC voltage is low er than the setting value
Low Volt 2

4.7.5 Rectifier Settings
At the Settings screen, press
▲ or ▼ to select the ‘Rect Settings’ menu, then press the ENT key to confirm.
There are three screens, as shown in Figure 4-33.
Position En: N
HVSD: 59.0V
Default V: 53.5V
R-Posi: 1-1
Walk-in On: N
Walk-in: 8s
Interval T: 0s
AC OverV On: N
ACCurrLim: 30A

Press
▲ or ▼ to select the parameter you need, and press ◄ or ► to select the parameter value, then press the
ENT key to confirm. The value description of the rectifier parameters is listed in Table 4-14.

Value description
Position En
Y, N
Y
Y: The controller w ill prompt you to set the rectifier position after the rectifier
and controller are pow ered on.
N: You do not need to set the rectifier position
R-Posi
1 ~ 30
R-Posi: represented in tw o figures, the first figure represents the rectifier
number, the next figure represents the position number. Press the ENT key to
select the rectifier, press
◄ or ► to change the position number. When the
controller is communicating w ith a rectifier, the green indicator on the
corresponding rectifier will blink
HVSD
56V ~ 59V
59V
The rectifier over-voltage alarm w ill be generated w hen the rectifier output
voltage is higher than the setting value
Default V
48V ~ 58V
53.5V
‘Default V’ output occurs when rectifier communication is interrupted. This
setting value must be low er than the
‘HVSD’ voltage value
Walk-in On
Y, N
N
It means the rectifier voltage w ill rise from 0V to the
‘Default V’ value after the
‘Walk-in T’ value
Walk-in
8s ~ 128s
8s
Interval T
0s ~ 10s
0s
The controller can set the DC-DC interval start of the system rectifiers. Start
time = rectifier address * interval
AC OverV On
Y, N
N
The controller can set the rectifier to
‘Over Volt En’, meanw hile, the rectifier
can start forcibly. The controller w ill automatically set the rectifier w ith least
address to have this function. If the rectifier alw ays exceeds the normal
voltage for 60s, the function w ill be cancelled automatically
ACCurrLim
1A ~ 50A
30A
The controller limits the input current of the rectifier w ithin the AC current limit
range
