CONFIGURING THE ACU+ IDENTIFICATION OF RECTIFIERS
When rectifier modules are all installed prior to applying power and starting the system,
the order in which the ACU+ identifies the rectifiers is by serial number (lowest serial
number is Rect 1, next lowest is Rect 2, etc.). If you prefer the ACU+ to identify the
rectifiers by position in the system, perform the following procedure.
Procedure
1) With the Main screen displayed, press ENT to go to the Main Menu. Navigate to
and select “Settings” (ENT).
2) If a password screen opens, a password must be entered to allow the User to
make adjustments. If a password was previously entered and has not yet timed
out, skip this step and proceed to step 3). Otherwise, to enter a password, with
the cursor at the User Name field (default is “Admin”), press the down arrow key
to move cursor down to the password line. Press ENT. “0” is highlighted. Press
the up arrow key once to change the “0” to”1” (default password is “1”), then
press ENT twice. (Note: If you have been assigned a unique User Name and
password, follow this procedure to enter these.)
3) With the Settings menu screen displayed, navigate to and select “Rectifier”
(ENT).
4) Navigate to “Rect #” (# is used here to represent the rectifier identification
number). Press ENT. The rectifier # menu screen is displayed, and the green
LED on one rectifier starts flashing. This is the rectifier currently identified by the
ACU+ as rectifier #. (If this is not the rectifier you want, press ESC to return to
rectifier menu screen and select a different rectifier.)
5) Navigate to and select “Rectifier ID”. Press ENT. Use the up or down keys to
change the ACU+ identification number for the flashing rectifier. Press ENT.
6) Press ESC to return to rectifier menu screen.
7) Repeat steps 4) through 6) for each of the remaining rectifiers in the system.
8) When you have finished selecting identification numbers for all rectifiers,
repeatedly press ESC to return to the Main Menu.
9) Navigate to and select “Manual” (ENT) / “Rectifier” (ENT) / “All Rect Ctrl”
(ENT).
10) Navigate to “Confirm ID/PH”. Press ENT. “Yes” highlights.
11) Press ENT to select the operation. Press ENT again to confirm.
Note: Check your numbering to be sure it is correct. If there where conflicts in your
numbering, rectifiers with conflicts will be assigned the next available
sequential number.
12) Return to the Main screen by repeatedly pressing ESC (escape).
