1.1 Main operating information
1.1.1 Noises
● Rhythmic noises are normal during operation.
● Specific noises can occur for several minutes after start-up.
1.1.2 UV lamp service life
The Analyzer module DEFOR uses a UV lamp as light source. The UV lamp has a limited service life and probably needs to be replaced several times during the overall operating time.
Status messages of increasing importance are activated automatically when the light
intensity of the UV lamp weakens (→ p. 16 [7]).
● UV lamp service life → p. 26, §5.7
● Display of the operating hours with the PC software “SOPAS ET” → p. 14,
§4.1
1.2 Application limitations
It is possible that another gas component contained in the sample gas can influence the
analysis of the desired measuring component (cross-sensitivity).
In such a case, a constant concentration of the “interfering gas” creates a constant deviation from the true measured value every time (constant characteristic curve offset). The
deviation varies accordingly when the interfering gas concentration fluctuates.
Important Information
● Cross-sensitivity against a certain gas is minimized automatically when the
DEFOR also measures the concentration of this gas.
● The cross-sensitivity can be minimized through computation in the control
unit when the interfering gas concentration is measured with a different
Analyzer module in the GMS800.

Product Description
2.1 Measuring system
Measuring principle
The Analyzer module DEFOR uses the fact that some gases have a specific absorption
characteristic in the ultraviolet light range. For this purpose, UV light is radiated through the
sample gas. The concentration of a gas component in a gas mixture can be determined
through suitable selection of the light wavelength and selective absorption measurement.
The Analyzer module DEFOR can, in this way, analyze the concentration of the gases Cl
H
S, NO, NO2, NH3, SO2 and further gases.
2
The Analyzer module DEFOR can simultaneously measure up to 3 gas components.
Measuring method
● The Analyzer module DEFOR uses interference filter correlation (IFC) for most gas components. Measuring and reference radiation are created alternately by swiveling two different interference filters into the beam path (filter wheel [2a]).
● Gas filter correlation (UVRAS) is used for NO. This method creates the reference radiation by swiveling a gas filter filled with the relevant gas into the beam path (filter wheel
[2b]).
● Both measuring methods are combined for joint measurement of NO and other gases
(both filter wheels [2a]+[2b] are used).
● The physical state of the measuring system is captured and compensated using a reference beam path through a reference cuvette.
,
2
Analyzer module layout
– Beam source is a special UV gas discharge lamp (→ p. 8, Fig. 1 [1]) that emits both broad-
band as well as NO-specific radiation components.
– Thermostat-controlled filter wheel unit [2] keeps the optic filters at a constant tempera-
ture. This minimizes the influence of external temperature changes.
– Lenses [3][8], beam splitter [4] and mirror [5] direct the beam path.
– Sample gas flows through sample cuvette [6]. Reference cuvette [7] is either filled with
a neutral gas or has span gas flowing through (option).
– Detectors [9] capture the radiation intensity created with the various filters.
– Measurement signals are amplified electronically and digitally evaluated. The structure
symmetry compensates proportional and symmetric signal drifts in the best possible
way.
–The measuring system can be fitted with an adjustment unit ([10] → p. 10, § 2.2.1).
The specific properties of the desired measuring components and the desired
physical measuring range each demand an individual metrological concept for
the Analyzer module.

2.2.1 Adjustment unit
The adjustment unit simplifies and accelerates routine adjustments.
Zero gas flows through the Analyzer module during an adjustment procedure with an
adjustment unit. The first step is a zero point adjustment. An optical filter is swiveled automatically into the beam path of the sample cuvette for the subsequent reference point
adjustment – and thus simulates the presence of a span gas in the sample cuvette. The
nominal values of this simulation are determined at the manufacturer's factory.
This means only a zero gas is required for an adjustment procedure with adjustment unit; a
span gas for reference point adjustment is not necessary. The procedure can be started
manually or can run automatically (requires automated zero gas feed).
The adjustment unit should be checked and readjusted in larger intervals during operation (recommendation: Every 6 months). For this purpose, the Analyzer module must be adjusted with real test gases beforehand.
2.2.2 Process cuvette
The versions with process cuvette are intended for applications with dangerous sample
gases where it must be ensured the sample gas does not flow into the gas analyzer when a
window of the sample cuvette becomes leaky.
In the process cuvette, the measuring compartment is flanked by purge gas compartments
through which purge gas flows continuously (→ Fig. 2). When a measuring compartment
window is leaky, the emerging sample gas flows into the purge gas compartment and from
there out of the gas analyzer with the purge gas.
The GMS800 therefore requires continuous purge gas for versions with a process cuvette
(→ p. 12, §3.2).

Enclosure
1 Install an external continuous purge gas supply for GMS800.
Suitable purge gas: Chemically neutral gas (inert gas) or gas mixture suitable for diluting and transporting the measured gas without danger.
2 Feed the purge gas through the “purge gas inlet“ gas connection on the enclosure.
Allowable pressure and volume flow: → p. 25, §5.3.2
3 Install a gas line on the “purge gas outlet” through which the purge gas and emerged
sample gas are reliably discharged.
▸
Lead the gas line to a safe position where emerged sample gas cannot create any
danger.
▸
Recommendation: Attach appropriate warning signs to the gas line or gas outlet
informing about the hazardousness of the sample gas.

– Damping metrological measured value fluctuations (noise)
– Smoothing fluctuating measured values when only the average value is relevant
Damping is done in the Analyzer module and therefore affects all measured value displays
and outputs. It is also active during an adjustment procedure.
● Increasing damping normally increases the reaction time (90% time) of the
gas analysis system accordingly.
● Reducing damping can possibly increase the measurement signal “noise”
(measuring turbulence).
● Time constant = 0 s means: No damping.
CAUTION: Risk of incorrect adjustment
The “Measuring time, test gas” must be at least 150% of the set damping time
constant during adjustments.
▸
When damping has been reset or increased: Check whether adjustment
settings need to be adapted.
Dynamic damping
“Dynamic damping” serves to compensate measured value fluctuations without significantly increasing the reaction time. Dynamic damping is automatically deactivated when
the measured value changes rapidly and strongly as against “normal” damping. This allows
“smoothing” continuous minor measured value fluctuations but rapid measured value
changes are still displayed without delay. Dynamic behavior is determined with the “Threshold” parameter:
– When the measured values change only slowly, dynamic damping functions as constant
damping.
– When the difference of successive measured values is greater than the set limit,
dynamic damping is terminated automatically and remains disabled as long as the
measured values continue to change rapidly.
– Dynamic damping is active again when measured value differences are below the limit
again (which means measured values changes remain slight).
Dynamic damping also affects all measured value displays and outputs.

4.3.4 Drift limit values
Purpose
Analyzer module drifts are caused, for example, by contamination, mechanical changes or
aging effects. The total drift (i.e. the deviation from original state) increases gradually. It is
not practical to keep compensating an ever increasing total drift through computation.
Inspect and reset the Analyzer module when total drift has become very large.
Drift limit values monitor total drift automatically. These also protect against erroneous
adjustments.
Functionality
After every adjustment, an Analyzer module compares the calculated total drift with the
drift limit value. Drift limit value violation is reported in two stages:
● Status “M” (Maintenance request) is activated when the total drift reaches 100 … 120%
of the drift limit value.
● Status “F” (Failure) is activated when the total drift reaches more than 120% of the drift
limit value.
● When an adjustment procedure shows that a calculated drift has reached more than
150% of the drift limit value, the result from this adjustment procedure is ignored and
the previous adjustment remains valid.
Functions in SOPAS ET
● The drift limit values are set in the factory (standard value: 10%).
● A Service function is available to reset all drift values to “0” (Drift reset).
This is useful after Analyzer module maintenance when this has established a new original state.
4.3.5 Deleting adjustment results
The “Delete results” function deletes all determined drift values of a measuring component. Drift limit values then refer to new drift values.
The data of the previous adjustment which was performed before are then no longer displayed. Test gas settings (e. g. nominal value) are not changed.
CAUTION: Risk of incorrect adjustment
If very large drift values are displayed after a manual adjustment procedure
(→ Operating Instructions “Basic Control Unit (BCU)”), a test gas used probably
did not match the relevant test gas setting or gas feed was interrupted – and
the adjustment result was still accepted.
▸
Do not delete incorrect adjustment results, but repeat the adjustment carefully.
▸
Do not use the deletion of adjustment results to nullify large drift values
caused by extensive physical changes of an Analyzer module. Instead,
clean the Analyzer module or perform an adjustment.
▸
After an Analyzer module has been cleaned, altered or exchanged:
Delete the relevant adjustment results and perform an adjustment.

Technical Data
If not specified otherwise, the metrological specifications in relation to the
physical measuring range are applicable (see order documents). The physical
measuring range is usually identical with the largest measuring range. The
same values apply for all other measuring ranges.
If, however, the Analyzer module was manufactured with “higher measuring
precision” (option), measuring precision is increased in range 0 … 20% of the
physical measuring range. The measurement specifications in this range are
then applicable in relation to 20% of the physical measuring range.
