5.6.2 Analog Input Alarms
The top right side of the Alarms tab presents eight analog Input alarm references and their
associated indicators. The four analog Input Greater Than Limit and four Less Than Limit
fields refer to alarm set points set on the
Analog Inputs
tab and will be discussed in more
detail in Section 5.17.
5.6.3 Analysis Alarms
The bottom half of the tab presents the analysis alarms for each of the streams. Each stream
has 6 available types of gas runs , each with its own set of alarms.
• High Alarm – is the first warning set point in a concentration range where the operator may
need to be alerted of a situation in the process.
•
High High Alarm – is the second warning set point in a concentration range where the
operator may need to take actions to alleviate this alarm. Many users will use this set point
to “Shut in” the process being monitored.
•
Deviation Alarm – is an alarm when consequent runs vary from each other by a greater
percentage than the value set on the Streams Tab. This alarm is generally disabled for the
H2S Run, as it is of little value for H2S Runs – it is expected that some degree of variation
in H2S concentration from analysis to analysis on the normal sample stream will occur.
•
Lock Alarm - This alarm will lock the analyzer in what ever stream it is currently in if it
exceeds the limit value. All alarm types can be configured to trigger specific relays and/or
outputs. To enable specific outputs for each alarm, simply put a checkmark in the desired
checkboxes in the Actions box.
