“Start”: The options include “FC”, “BC” and “Test”. If system is not configured with
any battery, the control would be invalid. If there is AC power off alarm, or the
busbar voltage is too low, the BC and battery test control will not be executed by
the system. No battery test control can be conducted when the rectifier
communication is interrupted. Finally, after the battery test, the battery management
mode will be changed from “Manual” to “Auto” automatically.
“Battery”: The options include “Reconnect” and “Disconnect”. If there is no battery,
or there is a battery alarm, the battery operations will be invalid.
“Load”: The options include “Reconnect” and “Disconnect”.
The following maintenance over the rectifier can be conducted only when the power
system is in the FC state.
”RectTrim”: Range: 42V ~ 58V. It can be used to improve the current sharing
among rectifiers. Note that the value of this parameter cannot exceed the
over-voltage alarm point, or the parameter will be invalid.
