Component Low; Clock Error; Tcf Error - ABB PGC2000 Operation And Service Manual

* Retention Time High—activates when retention time exceeds the upper setpoint.
* Response Factor High—activates when response factor exceeds the upper setpoint.

Component Low

When "Component Low:" appears as the main alarm, one or more component alarms appears below
the main alarm. Typical Component Low alarms and their descriptions are:
* Component Low Low—activates when a component is below "low low" setpoint.
* Component Low—activates when a component is below "low" setpoint but above "low low" setpoint.
* Retention Time Low—activates when retention time is below lower setpoint.
* Response Factor Low—activates when response factor is below lower setpoint.

Clock Error

When "Clock Error:" appears as the main alarm, one or more clock alarms appears below the main
alarm. Typical clock alarms are:
* No Active Streams—activates when the status of all streams in the stream table has been set to
inactive. To clear this alarm set at least one stream's status to active.
* Memory Shortage < 20%—activates when the GCC is short of memory. This is usually caused by
chromatogram storage. To clear this alarm return all memory that is being used for chromatogram
storage back to the operating system and reduce the number of points being saved by
Chromatogram Storage function.
* Auto Zero + Over Range—activates when program is unable to autozero because the signal is out
of range high.
* Auto Zero - Over Range—activates when program is unable to autozero because the signal is out of
range low.
* Bad Base Projection Forward—activates when the beginning of a peak was not defined in the
analysis.
* Bad Base Projection Backward—activates when the end of a peak was not defined in the analysis.
* A/D Buffer Overrun—activates when the analog-to-digital algorithm was unable to perform a
conversion based on the analog signal provided.
* A/D Conversion Error—activates when the analog-to-digital algorithm was unable to perform a
conversion.

TCF Error

When "TCF Error:" appears as the main alarm, one or more time-coded function alarms appears
below the main alarm. These alarms are cleared by correcting the associated method entry
designated by the alarm. Typical TCF alarms and their descriptions are:
* Auto Zero During Noise—activates when auto zero is performed during noise calculation.
* Auto Zero During Gate—activates when auto zero is performed during forced gate.
