6.
From the Main screen, press ENT to go to the “Main Menu” screen.
7.
From the Main Menu, select a submenu by repetitively pressing the up or down arrow key. The selected
submenu will be indicated by the cursor. Press ENT to open the submenu.
NOTE!
Repeatedly press the “ESC” key to return in reverse order level by level from any submenu until
the Main screen appears.
8.
Verify and set the ACU+ controller as required for your application. Refer to the ACU+ Instructions
(UM1M820BNA or UM1M820DNA400) for procedures. Note that you will have to program the ACU+ for
any temperature probes and external inputs/outputs connected to the IB2 Interface Board, optional EIB
Interface Board, and optional SM-DU+ Shunt Interface Board.
NOTE!
When setting total rectifier or total converter current limit, the set point to each unit is the total
set point divided by the number of units. For example, if the system contains five rectifiers and the
current limit is set to 150 amps then each rectifier has a current limit set point of 30 amps. If one or
more rectifiers or converters are removed or fail it will take several seconds for the individual set points
to the remaining rectifiers or converters to be reset. In the example given, if one rectifier is removed the
current limit set point will drop to 120 amps (30 amps times four remaining rectifiers) until the controller
can send updated set points to the remaining rectifiers. This takes a couple communication cycles
(several seconds) after which each rectifier would have a new set point of 37.5 amps for a total of 150
amps. The total current limit of the rectifiers and converters should not be set such that the loss of the
redundant rectifiers or converters will cause this temporary set point to drop below the actual maximum
expected load. If batteries are used on the rectifier output, the batteries should support the load until
the current limit set points can be re-established due to loss of a rectifier.
Verifying the Configuration File
Your ACU+ was programmed with a configuration file that sets all adjustable parameters. The version number
of the configuration file can be found on the configuration drawing (C-drawing) that is supplied with your power
system documentation, and on a label located on the ACU+. You can verify that the correct configuration file
has been loaded into your ACU+ by performing the following procedure.
NOTE!
The quantity of LVD’s and shunt values for your specific system may be different from the
values shown on the C-drawing.
Procedure
NOTE!
When viewing any of the following screens, if a key is not depressed within approximately 10
seconds, the ACU+ will automatically return to the Main screen.
1.
With the Main screen displayed, press ESC. A screen displays the serial number and software version.
2.
Press ENT. A screen displays the hardware version and MAC address.
3.
Press ENT. A screen displays the configuration version number.
