Error and Caution Display Messages

Various error and caution message codes can be shown on the display. A diagnostic

event can be configured by the user to be shown as either an error or caution

message, or can be set to not appear on the display. The action of each type is:

 Caution message codes are shown at the end of the regular scroll list, when a

caution is present. Scrolling continues for all display items.

 Error message codes override all regular display items and only the error

message codes are displayed. Scrolling stops for regular display items when

an error is displayed.

Once an error or caution occurs, the display continues to show the error or caution

code until it is cleared. The codes persist across power outages and continue to

display after the meter is powered down and back up. The error or caution codes are

read and cleared by NES System Software via PLC communication with the Data

Concentrator, or directly with the Provisioning Tool via the meter optical port.

All error and caution message codes can be read by the Data Concentrator and sent

to NES System Software, even when not selected to appear on the display.

If more than one error or caution is active, the displayed characters are a

combination of the error or caution values. See “Self Tests and Diagnostic Messages”

on page 1 for a list of the diagnostic messages and an explanation of display codes.

Display Value ID Code

The display value ID code is the user configurable 1 to 4 character alpha/numeric

identifying code for the value currently shown in the 8-digit value field of the meter

display. Different codes are used for power values and error and caution diagnostic

values. See the NES Provisioning Tool User’s Guide for more information on

creating value ID codes. Figure 3.2 shows the 4-character display value ID location.
