Display Alarms
The Display Alarm feature provides two independently configurable
alarms for transmitters with the display/keypad option. Each alarm tracks
a selected quantity, with a freely configurable limit values. Each alarm
also has a configurable hysteresis value to prevent unnecessary triggering
when the measurement fluctuates around an alarm limit. The alarms can
be configured for any quantity supported by the transmitter. The
configuration of the Display Alarms can only be done using the
display/keypad option.
You can have the alarm activate inside or outside the specified range by
setting the limits correctly:
- To have the alarm activate when the measured quantity is outside the
specified range, set the
Act. above
limit higher than the
Act. below
limit.
- To have the alarm activate when the measured quantity is inside the
range, set the
Act. above
limit lower than the
Act. below
limit.
The alarm limits are shown on the graph display as thicker dotted lines.
When a display alarm is activated, the automatic scaling of the graph
display always keeps the limits in view.
