Setting Up Global Inputs/
Outputs
While following the programming instructions for this submenu, refer
to the menu map in Figure A-4 on page A-4.
1. To enter the
GLOBAL menu, press [F3]=GLOBL.
2. To enter the I/O submenu, press [F3]= I/O.
• Press [F1] to set up error handling, or
• Press [F2] to set up any inputs or outputs.
Proceed to the appropriate section for step-by-step instructions on
each of the two options offered above.
Note: Be sure to record all programmed data in Appendix B, Data
Records.
Selecting Error Handling This menu option permits programming of the manner in which the
Model DF868’s measurements respond during an error condition. See
Chapter 2, Error Codes and Screen Messages, of the Service Manual
for a discussion of the built-in error codes.
1. At the
I/O screen, press [F1] to select the Error option.
2. Press
[F1] if you want the DF868 to Hold the last “good” reading
and continues to totalize, based on that reading, or press
[F2],
No Up, if you want the meter to stop totalizing.
3. Press
[F1] to disable 2-path Error Handling, or press [F2] to enable
2-path error handling.
The
2-path error handling option is intended for applications where
two sets of transducers are installed in the same location in the same
pipe to improve accuracy and the meter is operated in
AVE mode. With
this function enabled, the Model DF868 performs error handling only
if both
channels are in error. If this function is disabled, error
handling occurs when either
channel goes into error.
Specific responses of the totalizer to the 2-path error handling option
are listed in Table 1-19 below.
Table 1-19: 2-Path Error Response Options
Option Totalizer Response
NO Outputs the average of CH1 and CH2 totals, regard-
less of the error state of either channel.
YES 1. If one channel is in error, totalizing continues.
2. If both channels are in error and “No Up” is
selected, totalizing stops.
