Table 5-17 Value description of rectifier settings

Parameter		Range	Default		Value description
					The rectifier over voltage alarm will be
Rect Over Volt	56V ~ 59V		59V		raised when the rectifier output voltage is		The “Default Volt” must be
					higher than the “Rect Over Volt”		lower than the “Rect Over Volt”
Default Volt	48V ~ 58V		53.5V
Walkin Enabled		Y, N	N		The output soft start function means the	rectifier voltage will rise from 0V

					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
HVSD Time	50s ~ 300s		300s		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
