Analyzer Start-Up Procedure
Turn the power switch ON and allow the instrument to warm up for at least three minutes. During this time,
the gas values on the screen will show “********”. While the instrument is warming up, the user will be
prevented from accessing the calibration screens since the sensors have not had enough time to provide
accurate data. It is recommended that the instrument is powered on for at least five minutes prior to use,
although measurements can be taken within only three.
Sampling Criteria
Accurate readings are only possible if the sample is taken from a clean (free of excess carbon buildup)
sample port. The current state-of-the-art technology associated with infrared gas detection requires that a
clean, soot free sample be available for analysis. This will also increase the life of the filter elements, and
reduce the possibility that soot will enter the unit and contaminate the sensors.
On a furnace, the ideal port would be found on SSi’s Sample Port (Part Number 20264). This sample port
contains a high-temperature filter that contains the same element that is in the filter on the side of the
analyzer. This filter will not only prevent contaminants from entering the analyzer, but since the filter is at
the furnace it will also protect the sample lines from the furnace to the analyzer.
SSi Manual #4563 Rev. D Page 6 Multi-Gas Model 6000
On a generator, a dedicated sample port should be available. This sample port should be blown out before it
is used, which will remove any soot that has accumulated in the line.
The ideal flow rate for sampling should be between 1.0 and 1.5 Standard Cubic Feet per Hour (SCFH). A
visual indication of flow rate can be obtained through the flow meter located on the face of the enclosure, or
by the digital representation of flow on the left side of the display screen. The flow meter on the outside of
the enclosure also contains a dial that allows the user to restrict the flow, if necessary, to maintain an
appropriate flow rate. If the sample gas is not under pressure, the internal pump can be used to extract it.
For additional information on the operation of the pump, please refer to the section
option 4).
Pump Control

Filters
The side of the enclosure contains a large bowl filter that is intended to prevent soot and other contaminants
from entering the instrument. Periodic inspection of this filter will ensure reliable operation of the MGA6000.
When this element is new, it is a white/eggshell color. As this filter becomes dirty it will turn black and the
flow rate of the analyzer will begin to diminish. Replacing the filter element is as simple as unscrewing the
clear bowl from the filter housing, and unscrewing the retaining plug at the base of the element.
Information on replacement filters can be found in the section of this manual entitled “Spare Parts”.
Condensation / Moisture
When a hot gas is cooled rapidly, moisture in the gas can condense and form water. This water can collect
in the sample tubing and eventually enter the bowl filter. Care must be taken to ensure that no water enters
the unit, as this will cause permanent, irreversible damage to the sensors. The unit should be closely
monitored during operation to determine if moisture is collecting in the bowl filter. If this is the case, the
bowl filter basin can be removed and emptied by unscrewing it. Although water in the bowl filter will not
cause damage to the unit, this filter should not be used as a condensation receptacle. If moisture has
collected in the bowl filter, sampling should be stopped, and steps should be taken to prevent this from
continuing before operation is resumed.

auto mode, this message will read “Pump = AUTO”.
Main Display Setup
IR Status – Menu Page 2
Depending on the configuration of the instrument, this
screen may not contain all of the information shown in
the example. For one- and two-gas configurations, the
“Calculated” values will not be shown, since there is not
enough information available for the instrument to
compute the percent carbon. When the instrument is
configured with three gases (CO, CO2, and CH4), carbon
percentage can be calculated by the instrument, The IR
Status Display provides the user with the calculated
carbon percentage (%C) from two different sources
(probe and infrared). It provides information to allow
the atmosphere controller to be “tuned” to match the
information from the 3-gas analyzer.
To obtain the most information from this screen, data from the carbon probe must be entered. This can
either be done manually or automatically via RS485 communications. This information is displayed at the
right hand side of the screen under the heading

• FC TC= The furnace thermocouple value, or the furnace temperature.
• PB MV= The millivoltage from the carbon probe.
• PB TC= The probe thermocouple value, or the probe temperature.
• COF= The CO Factor value read from the SSi, Honeywell, Barber Colman, Yokogawa, or other
atmosphere controller.
• PF= The Process Factor value read from the Marathon Sensors atmosphere controller.

SSi Manual #4563 Rev. D Page 9 Multi-Gas Model 6000
• Temperature Units = This determines the measurement units for temperature. Enter 0 for
Fahrenheit (degrees F) or 1 for Celsius (degrees C).
Although it is possible to enter the data manually using the keypad, the atmosphere controller should be
utilized to provide the data automatically if possible. When the data is entered automatically, it will change
as the composition of the atmosphere changes. This will allow for a more reasonable correlation between
the values from the MGA and the values from the probe.
The probe information can also be used to ensure that the pump operates only when the conditions are right
for sampling. This can be used to prevent damage to the instrument if the pump is left running as the
furnace cools or when the conditions deviate from pre-determined parameters. For additional information on
operating the pump in “Auto Sample” mode, please refer to the section titled
option 17).
Measurement of Infrared % Carbon (IR %C)
To accurately measure the % carbon in a furnace atmosphere, the instrument will need to know the values
of CO, CO2, and CH4 and the temperature of the gas being measured. At the left side of the screen, under
the heading
the furnace temperature (FC TC) value, will result in the calculation of the IR % Carbon (IR %C). This is
displayed in the center of the screen, under the heading
temperature information has not been entered correctly the resulting carbon calculation
For best results, it is recommended that the temperature information be entered automatically from either
the atmosphere controller or the temperature controller.
Measurement of Probe % Carbon (PB %C)
The measurement of the probe % carbon requires three pieces of information to be entered. These are the
probe millivolts (PB MV), probe temperature (PB TC), and either the COF or the PF (depending on the type
of atmosphere controller you are using). The probe millivolts and probe temperatures are entered on the
right side of the page, under the heading
determine the manufacturer of the atmosphere control instrument you are using. If SSi, Honeywell, Barber
Colman, Yokogawa, or anyone other than Marathon Sensors manufactures the instrument, then it will
contain a CO Factor (COF) adjustment variable. If the user is using a Marathon Sensors instrument, then
this variable is called a Process Factor (PF) adjustment. Only one of these (COF or PF) will be used at any
one time, and the other will not be relevant. If the instrument has a CO Factor adjustment variable, then
use the up or down arrow keys to go to the appropriate field and type in the value that is stored in your
atmosphere control instrument. After the value is entered, an asterisk (*) will appear next to the number.
This lets the user know that the CO Factor is being used for the calculations, not the Process Factor. If the
instrument has a Process Factor adjustment variable, then this value should be entered in the “PF =” slot,
which will result in the asterisk appearing by that number entered.
The calculation of probe % carbon is no different from the % carbon as displayed on the atmosphere
controller. The algorithm used by both instruments in their calculations is identical. The reason the
information is entered into the MGA is not to calculate the probe % carbon, but to enable the MGA to
compute the suggested COF / PF. Without knowing the current instrument values, it cannot compute the
suggested values.
What is a CO Factor or a Process Factor?
The carbon probe is measuring the amount of oxygen in the atmosphere. Knowing the amount of oxygen,
the atmosphere controller can determine the percentage of carbon. The calculation that the instrument uses
to translate oxygen concentration into percent carbon is based on a theoretically pure atmosphere being
present in the furnace. The composition of this theoretically pure atmosphere is 40% hydrogen (H2), 40%

nitrogen (N2), and 20% carbon monoxide (CO). In many situations, the measured amount of CO is less
than the theoretically exact 20%. This can be due to a variety of factors including seasonal changes in
natural gas composition and incomplete gas cracking in an endothermic generator. The CO Factor and
Process Factor adjustments are intended to make adjustments to the calculation to accommodate differences
between theoretical and actual gas compositions.
Suggested COF / PF
Between the two methods of determining % carbon (probe and infrared), the infrared is considered to be
more accurate. This is because the infrared analyzer evaluates the levels of three gases (CO, CO2, and CH4)
to make its calculation, instead of just using % oxygen like the probe does. At the bottom of the middle
display column,
making a comparison between where the probe is actually reading and where it should be reading. The
suggested COF and PF values can be entered into your atmosphere controller to make it display the same %
carbon reading as the MGA6000. By performing periodic evaluations with the MGA6000 and making the
suggested modifications to the adjustment factor in the atmosphere controller, the user can be assured that
the continuous source of process data (the probe) is as accurate as possible. Of course, large changes in CO
Factor or Process Factor should be verified by shim stock analysis or other means to confirm the significance
of the change.
