1.6.2 Start button (F2)
A cycle may be executed by pressing the button labelled Start, which is then re-
labelled Stop.The cycle can then be stopped by pressing the same button, which
is then re-labelled Start. Start and Stop may also be actioned by toggling F2.
When a cycle is started, the analyser waits for the ending time of the first peak
and begins its peak detection between the starting time and the ending time. If a
peak is found, the peak that is detected and used for integration is presented in
yellow below the raw signal coming from the detectors.
During the cycle, the progress bar rises with time. The bar starts at the left and
ends at the right. The cycle length can be set in the CONFIGURATION-
CYCLE menu. During a peak, a green circle appears at the corresponding peak
of the upper grid alarm column (Al). When the peak detection process is
completed, the peak area is converted into the process value and displayed in the
grid beside the peak name in the value field. Then the analyser waits for other
peaks and applies the same procedure.
The cycle continues even if you exit the REAL-TIME
CHROMATOGRAM MENU.
It is not recommended to Stop a real time chromatogram during a
cycle.
1.6.3 Injection Mode
Use the Injection Mode radio control to select one of two injection modes. The
Manual mode executes one cycle after the Start button is pressed. The
Automatic mode restarts new cycles until the Stop button is pressed or the
Manual mode is selected.
1.6.4 Injection Status
The Injection Status radio control enables sample injection when the ON radio
control is selected and disables sample injection when the OFF radio control is
selected.
1.6.5 Enhanced View (Ultra only)
The Enhanced View radio control enables the chromatogram view to focus
between the Baseline and the Saturation line (see Figure 15). This enables the
user to clearly view the peaks on the chromatogram.

15 04400003A_0
The Range cannot be changed during a peak integration. When
Automatic ranging is selected, range selection will be automatically
based on the result of the last peak calculations.
If the peak selected is configured to ppb and the measurement
switches into Range 1, ppt measurement will be seen in Peak table.
If the measurement switches into Range 2, ppb measurement will be
seen in Peak table.
Note that when Threshold calibration is enabled, “Warning: Threshold
Calibration enabled”will be displayed in the chromatogram display with
Enhanced View On.
Note that when Span calibration is enabled, “Warning: Span Calibration
enabled”will be displayed in the chromatogram display with Enhanced View Off.
During both Threshold and Span calibration the Enhanced View radio control
will be disabled.
The colour displayed in the Alarm column (Al) of the peak grid indicates the
alarm status for each peak. The following table shows the meaning of each colour.

1.7 Historic Menu
1.7.1 Alarm Menu
Displays the last 200 system alarms, peak value alarms and event logs, and all
the active alarms.
1) System alarms:
•Low sample flow
When the sample flow goes below 10 cc/min with a sample flow set point
greater than 10 cc/min.

Quick Start Guide
SERVOPRO CHROMA/NANOCHROME/ULTRA Gas Analyser
17 04400003A_0
•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.

2) Peak value alarms
Peak value alarms do not impact the system status alarm dry contact output.
•Alarm 1 peak #
When the concentration of impurity is greater than the Alarm 1 for the peak.
•Alarm 2 peak #
When the concentration of impurity is greater than the Alarm 2 for the peak.
•Overscale peak #
When the concentration of impurity is greater than the actual scale of the
peak.
3) Peripheral alarms:
Some peripherals connected with the analyser may show their alarms/errors
status in the Historic Alarm menu. Refer to their User Manuals for more
information.
When a problem arises, a new alarm is generated and the button of the
HISTORIC ALARM menu turns red. If the menu is opened and an alarm is
still active, it turns yellow. If another alarm occurs, it turns red again. The
button will turn green when all alarms are resolved.
Every system alarm will activate or deactivate the system status alarm dry
contact output, depending on the settings in the CONFIGURATION
ALARM menu. Peak value alarm 1 and 2 each have a separate dry contact
output that is activated or deactivated, depending on the CONFIGURATION
ALARM menu, when the alarm thresholds are reached.
Some system functions, such as a real-time chromatogram, are disabled when
alarms are active. Rectify the problems before proceeding with your analysis.
When the problem is resolved, the same alarm message is displayed, but with
an “Ok” message (except for a “Plasma shut down” that is resolved with a
“Starting” and for the “Plasma OFF” that is resolved with a “Plasma ON”).
Example:
• If a “Low carrier flow” occurs, the following message is displayed:
(date) Low carrier flow: (hour)
• When the flow problem is rectified, the following message is displayed:
(date) Low carrier flow: Ok (hour)
