5.3.2 Alarm Severity
Indicates that an alarm exists but is not critical to the operation of
the unit. Use when testing for some condition that may occur from
time to time and there is a need to know when it happens.
Indicates that an alarm exists; typically is not critical but may
indicate or provide unexpected results.
Indicates that a malfunction exists that may affect the operation of
the unit and most likely will provide unexpected results. The fault
will keep any affected streams from having their data updated;
however, a fault would not stop a scheduled or manually initiated
calibration from occurring. Additionally, if the calibration corrects
the alarm condition, the alarm will be cleared.
This typically indicates that a maintenance problem exists.
Analysis processing will still occur, depending on the problem;
however, results will not be updated for any stream while this
condition exists. Default system faults are already defined.
Additionally, unless the user has a situation in which they want to
stop all stream data from being updated, they should not use this
category of alarm.
5.3.3 Pressure Regulator Alarm
If a pressure regulator alarm is in fault status, the following procedures will step
the user through the troubleshooting process. On occasion, these instructions may
take the user to other procedures. When those procedures are complete, the user
should return to these procedures to continue.
