5.6.3.2 Process Value Alarms
DO3 and DO4 outputs can indicate only one of the
following: sensor status, PV alarms, setpoint
deviation alarm limits, or setpoint ramping.
The use of the PV monitoring function precludes
the use of the Min/Max selection function for both
the PV and remote setpoint.
There are five alarm options and two possible limits for process value
alarms. Each alarm option uses the same limits. Use FCODE 103 to
set type of alarm.

Process value alarms, setpoint deviation alarms,
sensor status, and setpoint ramping all use DO3
and D04, and are mutually exclusive. If more than
one of these functions is set at a time the display
indicates ERROR during configuration.
The following table shows which outputs carry the selected alarms.
Only one of the indications can be on at any given time.
