4 Setting Up the MJ-XL Control Panel
Siemens Power Transmission & Distribution, Inc. 17
Note: Depending upon the version of software in
your MJ-X
L
Control Panel, your menus may be
slightly different than those described. If your
control panel does not support all of the fea-
tures described, please contact your Siemens
representative for details about obtaining the
latest version of the software.
4.2 Setup for Retrofit Panels
If you are retrofitting either a G. E. or Cooper regulator for
use with the Siemens MJ-X
L
Control Panel, please refer to
the respective Application Note. Contact your Siemens
representative for details.
4.3 Defining Your Regulator—
the <CONFIGURE> Menu
When the MJ-X
L
Control Panel is delivered pre-installed on
a regulator, many of the configuration variables are already
set. However, the MJ-X
L
Control Panel provides a wide
range of additional variables that can be used to make the
regulator perform more effectively in your system.
Variables in the <CONFIGURE> Menu are summarized in
Table 4.1 and explained in the following pages.
Figures 4.1 to 4.3 show typical Siemens regulator name-
plates. Refer to these figures for information that can be
obtained from Siemens regulator nameplates.
