Sensors Active; Sensors Held; Component High - ABB PGC2000 Operation And Service Manual

Sensors Active

When "Sensors Active:" appears as the main alarm, one or more sensor alarms appears below the
main alarm. "Sensors Active" appears when an alarm is active at the time you look at the Alarms
screen. Typical Sensors Active alarms and their descriptions are:
Sensor Alarms 1 to 5 are application-specific alarms. Descriptions of their use are
contained in the Data Package supplied with the analyzer.
* Sensor 5 Alarm: [user entered name]
* Sensor 4 Alarm: [user entered name]
* Sensor 3 Alarm: [user entered name]
* Sensor 2 Alarm: [user entered name]
* Sensor 1 Alarm: [user entered name]
* Purge Air—activates when purge air is lost. After purge air is restored the alarm resets.
* Carrier Gas—activates when carrier gas is lost. After carrier is restored the alarm resets.
* Low Oven Temp—activates when oven temperature goes below the lower setpoint. When
temperature comes back within the setpoints, the alarm resets.
* High Oven Temp—activates when oven temperature exceeds the upper setpoint. When
temperature comes back within the setpoints, the alarm resets.
* Low Standard Sample—activates when standard sample is low or missing. When the standard
sample is restored, the alarm resets.
* Sample Flow—activates when sample flow is lost. When the sample flow is restored, the alarm
resets.
* Low Fuel/N2/Dilution—activates when fuel/N2/dilution is lost. When it is restored the alarm resets.

Sensors Held

When "Sensors Held" appears as the main alarm, one or more sensor alarms appears below the
main alarm. "Sensors Held" appears when an alarm was active at some time during the analysis, but
before you looked at the Alarms screen. Typical Sensors Held alarms are the same as those for
Sensors Active.
You can manually reset Sensors Held alarms by entering the Alarms screen (after the problem is
corrected) and pressing the F2 (Clear Alarms and Exit) soft key. If you set Sensors Held to clear at
the end of the analysis, they will do so if the Sensors Active have cleared.

Component High

When "Component High:" appears as the main alarm, one or more component alarms appears below
the main alarm. Typical Component High alarms and their descriptions are:
* Component High High—activates when a component exceeds the "high high" setpoint.
* Component High—activates when a component exceeds the "high" setpoint but is within the "high
high" setpoint.
