1.4.2 Setting Up Inputs and Outputs
Set up the XMT868i’s inputs and outputs using the I/O submenu. While following the programming instructions, refer
to Figure 31 on page 10 and Figure 32 on page 11. Remember to record all programmed data in Appendix B, Data
Records .The I/O submenu consists of the following options:
• Error Handling - program the meter’s response during an error condition
• Options - set up any option cards and the Slot 0 analog outputs
• LCD - set up the LCD display (refer to Chapter 2, Displaying Data )
To enter the I/O submenu:
1. From the PROGRAM menu, scroll to GLOBL and press [Enter] .
2. Scroll to I/O and press [Enter] .
Note: In this section, Slot 1 appears as an option only if a suitable option card is installed in Slot 1.
1.4.2.1 Setting Up Error Handling
This menu option lets you set how the XMT868i will handle the outputs for measurements and average (two-path)
measurements during an error condition. See Chapter 2, Error Codes , in the Service Manual for a discussion of the
built-in error codes.
1. In the Global I/O option, scroll to ERROR and press [Enter] .
2. Scroll to the desired Error Handling selection (as shown in Table 15 and Table 16 on page 27).
a.
If you selected Other , enter the 4-20 mA Error Level (the number of milliamps the analog output will put out during
a fault condition). Enter a whole number between 0 and 22, and press
[Enter]
.
See Table 15 and Table 16 on page 27 for a description of the error handling options available and how the totalizers
and display respond to them for a single and two-channel meter.
Table 15: Error Options and Responses, Single-Channel Meter
Option Output Response Totalizer Response
HOLD Holds the last “good” reading Holds the last “good” reading and continues to
totalize, based on that reading
LOW Forces the outputs to the low set point Stops totalizing
HIGH Forces the outputs to the high set point Stops totalizing
HHIGH Forces the outputs

10% above the high set point Stops totalizing
OTHER Allows user to enter 4-20 mA error level in mA. Sends analog outputs to entered mA level when
a fault occurs.
