Rect Expansion
•
Inactive:
Select this option if this is the only ACU+
Controller in the power system.
•
Primary:
Select this option if the power system
consists of multiple bays with multiple ACU+
Controllers, and this ACU+ Controller is to be the
Primary Controller. Note that only one (1) ACU+
Controller can be set as the Primary Controller.
•
Secondary:
Select this option if the power system
consists of multiple bays with multiple ACU+
Controllers, and this ACU+ Controller is to be a
Secondary Controller.
_____________________
Up to four (4) ACU+ Controllers can be connected
together when a power system requires a greater
number of rectifiers than can be controlled by a single
ACU+ Controller. One (1) Controller is designated as the
primary Controller, the others as secondary Controllers.
The rectifiers controlled by the secondary Controllers are
designated as RectifierGroup 2 through 4 in the menus.
Primary/Secondary Procedure:
Note:
Changing the Rectifier Expansion setting may take
more than 3 minutes for the ACU+ to configure the
feature.
1. Connect the ACU+ Controllers in the multiple bays
via the RS485 interface.
2. Set one of the ACU+ Controllers as the Primary
Controller via the
Rect Expansion
menu item in the
Power System "General" Parameters
menu.
3. Set all other ACU+ Controllers as Secondary
Controllers via the
Rect Expansion
menu item in the
Power System "General" Parameters
menu.
4. Set the Address of the ACU+ Controllers set as
Secondary Controllers to 201, 202, or 203 via the
Address (Slave)
menu item in the
Power System
"General" Parameters
menu. Note that each
Secondary Controller must be set to a different
address.
