4 Setting Up the MJ-X
L
Control Panel
4.1 Setup—Overview
MJ-X
L
Control Panel setup procedures allow you to cus-
tomize the control panel to your needs and to the environ-
ment in which it is installed. You can describe specific
regulator parameters and power-flow conditions, and
define automatic-mode operation. Previous generation
controllers used dip switch settings and jumpers for this
purpose. With the MJ-X
L
Control Panel, simply use front
panel touch-keys and the display screen to define the
operating environment. Also, the MJ-X
L
communication
facilities in conjunction with the MJXplorer software can
be used to set up the MJ-X
L
Control Panel.
The setup process for the MJ-X
L
Control Panel consists of
several steps:
Configuration
In this step, use the <CONFIGURE> Menu to describe
the regulator and the power distribution system.
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. Chapter 7 contains addi-
tional detail and background information to help you make
the proper selections.
