• High-High Alarm Enable
- If this box is checked then the limit value entered will be used as
an alarm point. The High-High Alarm also known as the Predictive Alarm Analysis (PAA)
alarm mode is an alarm mode that triggers when the live calculated concentration at any
point during the analysis cycle (except for the sample delay on the standard analysis
method) exceeds the High-High alarm set point. When the analyzer enters this PAA mode,
the concentration displayed on the LCD screen immediately begins to update with the live
concentration value once per second. In addition, any analog output or MODBUS register
that is currently outputting the stream normal concentration value will also output the live
value of the concentration once per second while the analyzer is in PAA mode.
When the analyzer is in PAA mode, this alarm will be listed in the Analyzer Alarm list, as
well as in the Event Log, and the red ALARM LED on the front panel of the analyzer will
also be lit. Any outputs associated with this alarm mode will also be triggered. Once the
concentration of the normal stream drops back below the PAA set point, the alarm LED will
turn off, PAA will be cleared from the Analyzer Alarm List, and any unlatched outputs
associated with PAA will return to their non-triggered state. Any latched outputs associated
with this alarm will have to be manually cleared through the GUI.
• High-High Alarm Duration - The number of seconds entered in this field represents the time
required for the High-High alarm to be active before the alarm would register. This would
alleviate the alarm bouncing on and off if the concentration reading was close to the alarm
set point.
• Lock Alarm Enable
- If this box is checked then the limit value entered will be used as an
alarm point. This alarm set point if pasted will lock the analyzer in whatever stream it is
currently and will not allow the analyzer to proceed to other enabled gas runs.
5.10.4 Calibration, Reference and Zero Gas Tabs
5.10.4.1 Calibration Tab
The
Calibration
tab is set up very similarly to the
Sample
tab, with a few notable differences.
The calibration run can be set up to automatically calibrate the analyzer and calculate a new
gain factor if the analyzer is equipped with the auto-calibration option. The Calibration run can
be triggered to start a number of ways such as: a discrete input, an automatic or manual
sequence entry, a timed schedule entry, through the keypad or simply by hitting the Stream
Calibration button.
If any analysis alarms have been triggered on the Sample Run (i.e. High or
High High), any calibration run triggered from the GUI will be put into the
run queue and not run until the alarm condition(s) has/have cleared.
