Analog Expander Setup Analog Expander Setup Analog Expander Setup 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 (see pictures above):
The upper window indicates an analog expander’s output channel.
The middle window selects a setup parameter to view or change.
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:
Press the SELECT button to activate the middle window.
Use the UP and DOWN arrow buttons to scroll to the desired parameter.
To change the parameter value:
Press the SELECT button to activate the lower window.
Use the UP and DOWN arrow buttons to select the desired value.
Press ENTER to confirm the new parameter setting, or press ESC to discard changes.
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:
When the middle window is highlighted, press the ENTER button.
You are returned to the upper window to select another analog output or exit the menu.
To exit the menu, press ESC.
The following table lists available analog output options.
Label Parameter Options Description
OutP Output
parameter See Appendix B Selects the measured parameter to
be transmitted through the analog
expander channel.
Lo Zero scale Low engineering scale (in primary
units) for the analog output
corresponding to a lowest (zero)
output current (0 or 4 mA)
Hi Full scale High engineering scale (in primary
units) for the analog output
corresponding to a highest output
current (1 or 20 mA)
