•
Low carrier flow
When the carrier flow falls below 5 cc/min for the plasma detector for 30
seconds,
a “Plasma #X on I/O Board #X shut down”
alarm will be initiated to
protect the system by turning off the #X plasma detector.
•
Plasma shut down
When a “Low carrier flow” alarm remains active for 30 seconds, turns the
plasma detector off.
•
Plasma OFF
When the cell signal counts are lower than the starting count, it indicates that
the plasma detector is physically off.
•
Starting
The plasma is restarted when the following is true
-
“Plasma off” alarm is active
-
“Low carrier flow” alarm
is inactive
-
Starting mode is automatic (
SYSTEM CONFIGURATION MENU
for
the
Starting mode
definition)
-
No cycle is progressing (real-time chromatogram stopped or between
cycles)
•
Plasma ON
When the cell signal counts go above the starting counts after a “Plasma OFF”,
it indicates that the plasma is physically on.
•
RTD problem
:
When an oven temperature falls below 10 degrees Celsius.
•
Carrier flow deviation
When the carrier flow is higher or lower than the carrier flow set point by 2
cc/min or more; the injection is still possible and the system continues to report
process values.
•
Oven temperature deviation
When an oven temperature is higher or lower than the oven temperature set
point by 2 degrees Celsius or more.
•
Communication problem
When the user interface (PC) cannot exchange any data with an electronic
board inside the analyser.
