Use “” or “” to select one page or one of the parameters, and “” or “” to
select the parameter value. Press “ENT” to confirm and save.
2. The value description of the parameters is listed below:
Table 5-17 Value description of rectifier settings
Parameter Range Default Value description
Rect Over Volt 56V ~ 59V 59V
The rectifier over voltage alarm will be
raised when the rectifier output voltage is
higher than the “Rect Over Volt”
Default Volt 48V ~ 58V 53.5V
The “Default Volt” must be
lower than the “Rect Over Volt”
Walkin Enabled Y, N N
Walkin Time 8s ~ 128s 10s
The output soft start function means the rectifier voltage will rise from 0V
to the “Default Volt” after the “Walkin Time”
Fan Speed Full Speed,
Half Speed
Half
speed
When set to “Half Speed”, the rectifier will regulate the fan speed
according to the temperature. When set to “Full Speed”, the fan will
operate at full speed
HVSD Time 50s ~ 300s 300s
The rectifier will shut off automatically upon over-voltage, and restart after
a certain delay to see whether it is still over-voltage then. That delay is set
through the parameter “HVSD Time”. If the rectifier’s output voltage is
normal within the delay, the rectifier is regarded normal; otherwise, the
rectifier will be locked out and auto-restart function will be disabled
