Advanced Configuration Functionality
AO diagnostic alarm
There are diagnostics that, when under active conditions, do not drive the analog output to
alarm level. The AO diagnostic alarm menu enables selection of these diagnostics to be
associated with an analog alarm. If any of the selected diagnostics are active, it will cause the
analog output to go to the configured alarm level. For a list of diagnostic alarms that can be
configured to drive an analog alarm, see Table 5-3.
