Setting the Mini Control Unit as Required for Your Application
General
Refer to the Mini Control Unit Instructions (UM1M831ANA) for additional information.
Temperature Probes: Depending on if controller temperature probe inputs are enabled or disabled in the
controller configuration, you may have to program the controller for any temperature probes being used. Note
that some temperature probe inputs may not be enabled by default. Refer to the C-drawing supplied with your
system to determine if temperature probe inputs are enabled and pre-programmed. Refer to “Setting
Temperature Sensors” in the “Common Tasks Performed via the Local Keypad and/or Web Interface” section of
the controller manual (UM1M831ANA) if temperature probe inputs require programming.
NOTE!
Verify the controller temperature probe configuration if temperature probes are installed from
the factory. Refer to the C-drawing supplied with your system.
NOTE!
When setting total rectifier current limit, the set point to each rectifier is the total set point
divided by the number of rectifiers. For example, if the system contains three rectifiers and the current
limit is set to 30 amps then each rectifier has a current limit set point of 10 amps. If one or more
rectifiers are removed or fails it will take several seconds for the individual set points to the remaining
rectifiers to be reset. In the example given, if one rectifier is removed the current limit set point will drop
to 20 amps (10 amps times two 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 15 amps for a total of 30 amps. The total current limit of the
rectifiers should not be set such that the loss of the redundant rectifiers 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 Mini Control Unit 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 Mini Control Unit. You can verify that the
correct configuration file has been loaded into your Mini Control Unit by performing the following procedure.
Procedure
1.
With the Main Screen displayed, press ESC. A screen displays the Mini Control Unit serial number.
Repeatedly press the ENT key to display the hardware version, software version, configuration file
number, file system, IP address, and MAC address.
2.
Press ESC to return to the Main Screen.
Checking Basic System Settings
Navigate through the controller menus and submenus to check system settings. You can adjust any parameter
as required. Note that these settings can also be checked (and changed if required) via the WEB Interface.
NOTE!
Repeatedly press the “ESC” key to return in reverse order level by level from any submenu until
the Main Menu appears.
