Configuring the ACU+ Identification of Converter Modules
When converters are all installed prior to applying power and starting the system, the
order in which the ACU+ identifies the converters is by serial number (lowest serial
number is Conv 1, next lowest is Conv 2, etc.).
If you prefer the ACU+ to identify the converters 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 “Converter”
(ENT).
4) Navigate to “Conv #” (# is used here to represent the converter identification
number). Press ENT. The converter # menu screen is displayed, and the green
LED on one converter starts flashing. This is the converter currently identified by
the ACU+ as converter #. (If this is not the converter you want, press ESC to
return to converter menu screen and select a different converter.)
