The DC Over Voltage alarm will be raised when the system DC output
voltage is higher than the value of Over Volt
The DC low voltage alarm will be raised when the system DC output
voltage is lower than the value of Low Volt 1. The value of the Low Volt 1
must be lower than that of the Over Volt
The DC under voltage alarm will be raised when the system DC output
voltage is lower than the value of Low Volt 2. The value of the Low Volt 2
must be lower than that of the Low Volt 1
Setting according to the actual instance
They can be reset when the shunt options are 'SET' in the system with load

'Y': The controller will prompt you to set rectifier position before the rectifier
and controller are powered on.
'N': You need not to set rectifier position
R-Posi: represented in two figures, the first figure represents the rectifier
number, the next figure reprents position number. Press ENT to select the
rectifier, press ◄ or ► to change position number. When the controller
communicates with the rectifier, the green indicator on the corresponding
rectifier will blink
The rectifier over voltage alarm will be raised when the rectifier output
voltage is higher than the HVSD voltage
Default output voltage when communication interrupted. Must be lower than
this value
