Conc. Alarm Valid (Relay)
Indicates whether the Concentration Alarm is Valid or not (Invalid).
When the status is Invalid, this field has a Red background.
When the Conc. Alarm relays are configured as Stream Indicators
rather than as Concentration Alarm Indicators:
Concentration Alarm 1 relay indicates StreamA selected for analysis.
- Energized (On) = StreamA selected
- De-energized (Off) = StreamA not selected
Concentration Alarm 2 relay indicates StreamB selected for analysis.
- Energized (On) = StreamB selected
- De-energized (Off) = StreamB not selected
Conc. alarm invalid relay (on Analyzer Data tab) indicates āInvalidā
concentration alarm when one of the following situations is true:
- Conc. Alarm Hard Enable is in Disable state, or
- Sample system is in shut-in/off state (check Analyzer system status), or
- During Startup time delay period (check Analyzer system status), or
- Conc. Alarm Soft Enable is in Disable state, or
- During Alarm clearing (check Analyzer system status), or
- Fail alarm activated before any one of the concentration alarms is
activated.
Concentration Alarm 1
Concentration Alarm 2
The current status of the Concentration Alarms (Alarm 1 and Alarm 2),
either ON or OFF. The ON status indicates that one (or both) of the
Concentration Alarms has exceeded its On-Threshold (trip-point)
value and Off-Threshold (alarm clear) value.
If the Concentration Alarms are disabled, the status of each alarm
will be displayed here, either ON or OFF. The Concentration Alarms
are disabled if Result Assignment (on the Alarm Setting and Stream
Switch Parameters dialog box) is set to 0-N/A.
If the status of these alarms is ON, these fields will have a Red back-
ground.
