SERVOPRO CHROMA Gas Analyser
61 04400001A / Revision 7
3) Generator Starting mode
• Manual:
the automatic re-start feature is disabled and any plasma power value
between 0 and 100% may be entered. It is useful when troubleshooting or re-
configuring the system.
• Automatic:
when the cell raw counts are lower than the cell Plasma starting
count value, a higher power will be applied to the cell to restart the plasma.
NOTE: The system checks if the plasma is OFF between cycles. This feature
is used only when the analyser has a plasma cell.
4) Range Mode
Manual : you may change range manually.
Automatic
: changes the range according to the result of the previous peak
integration. If the result of peak integration gives a value higher than 99% of the
range presently used, the analyser switches to the next higher range. The next
integration gives the proper result. If the result of a peak is lower than 90% of
the lower range currently set, the analyser switches to this lower range.
As this process is independent for all peaks, in Automatic ranging
the second peak range can stay the same even if the first peak
changes range.
5) Auto-Start on Boot-Up
When set to
Yes
, will try to start a cycle (or several cycles if The
Injection mode
has been set to Automatic ) on the analyser boot-up after all the alarms are
resolved.
6) Flow Set Point
Indicates the flows and the set point for each of them. The flow is controlled by
an autonomous electronic Pressure Regulator Board.
The Flow Set Point value is used by the flow control loop. In the third column of
the Flow Set Point grid, the real flow is displayed. There may be a delay after a
new set point is entered before the real flow is displayed and stabilized to the
specified set point. Change the set point by adjusting the value in the second
column for the corresponding flow. The range of the values that can be set
corresponds to the range of the associated flow sensor table (see
CONFIGURATION-FLOW menu).
