4 Setting Up the MJ-4A & MJ-4B Control Panel
4.1 Setup—Overview
MJ-4 Control Panel setup procedures allow you to custom-
ize the control panel to your needs and to the environment
in which it is installed. You can describe specific regulator
parameters and power-flow conditions, and define auto-
matic-mode operation. Previous generation controllers
used dip switch settings and jumpers for this purpose.
With the MJ-4 Control Panel, simply use front panel touch-
keys and the display screen to define the operating envi-
ronment. Also, the MJ-4 communication facilities in con-
junction with the MJXplorer software can be used to set
up the MJ-4 Control Panel.
The setup process for the MJ-4 Control Panel consists of
several steps:
Configuration
In this step, use the <CONFIGURE> Menu to describe
the regulator and the power distribution system. Use the
<ADV CONFIGURE> Menu to adjust optional or
advanced settings if desired.
Setpoints
In this step, use the <REGULATOR> Menu to define
Automatic Mode setpoints (voltage level, bandwidth, time
delay, etc.).
Logging Requirements
In this step, use the <LOG SETUP> Menu to define data
logging requirements (what values you want logged, how
often, under what conditions, etc.).
Security Definition
In this step, use the <PASSWORD> Menu to define pass-
words and to activate security protection.

Communications Definition
In this step, use the <COMMUNICATIONS> Menu to
define communications parameters (baud rate, unit
address, etc.).
This chapter describes each of the setup parameters, and
explains how they are defined. The Communications Mod-
ule Instruction book contains additional detail and back-
ground information to help you make the proper
selections.
Note: Depending upon the version of software in
your MJ-4 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.
