General Operation
General Functionality
The Display Module acts as a simple terminal that
allows a user to easily view metering parameters or
change configuration items. This is accomplished by
using three modes of operation: Display mode,
Program mode, and Edit mode.
Display mode allows any user to view any of the
measured parameters that the Powermonitor II
provides including metering information, harmonic
analysis (1403-MM only), and logging information.
The user also has the option of selecting default
screens which are displayed at power-up or after 30
minutes of non-activity.
Program mode allows a privileged user to issue
commands or select a parameter to modify. Program
mode provides a basic security system where each
Powermonitor II is password protected, and only one
entity can modify a Powermonitor II; an entity
includes one of the three possible Display Modules
or the Smart Communication Card. When a user is in
Program Mode, a flashing “P” is displayed at the
bottom right-hand corner of the Display Module.
Edit mode allows the privileged user to modify the
selected parameters. When a user is in Edit mode, the
parameter being modified flashes, and the flashing
“P” remains solid.
Key Functions
The Display Module has four keys located on its
front bezel: an Escape key, Up Arrow key, Down
Arrow key, and Enter key. These keys maintain their
same functionality for all of the Display Module’s
modes making the Display Module easy to use. The
functionality of the four keys is shown in Figure 4.1.
