Analog Expander Setup
The meter can provide 16 additional analog outputs via two optional AX-8
analog expanders that are connected through a serial RS-422 interface to
the meter port COM2. Each expander has its own address 0 or 1 on the
serial interface.
This menu allows you to assign parameters for the expanded analog outputs
and to specify their scales. For more information on configuring the analog
expander outputs in your meter, see “Programming the Analog Expander” in
Chapter 4.
To enter the menu, select the “AEPn” entry from the Main menu, and press
the ENTER button.
The expanded analog outputs are labeled in the following manner: analog
output channels A1-1 through A1-8 are associated with the analog expander
with address 0, while outputs A2-1 through A2-8 are associated with the
analog expander with address 1.
The menu uses three entries:
1. The upper window indicates an analog expander’s output
channel.
2. The middle window selects a setup parameter to view or
change.
3. The lower window displays the parameter value.
Use the UP and DOWN arrow buttons to scroll to the desired analog
expander channel.
To select a setup parameter:
1. Press the SELECT button to activate the middle window.
3. Use the UP and DOWN arrow buttons to scroll to the desired
parameter.
To change the parameter value:
1. Press the SELECT button to activate the lower window.
2. Use the UP and DOWN arrow buttons to select the
desired value.
3. Press ENTER to confirm the new parameter setting, or
press ESC to discard changes.
4. You are returned to the middle window to select and
configure another parameter, or confirm the analog output
settings and exit the menu.
To store your new settings after you configured all parameters:
1. When the middle window is highlighted, press the ENTER
button.
