Special Safety Instructions for Operating the EL6010 Gas Analyzer
Observe Safety
Precautions
Before starting any work on the EL6010 gas analyzer, observe all explosion-
protection safety precautions.
Do Not Work Where
There is a Risk of
Explosion
While there is a risk of explosion, do not work on current-bearing components,
except intrinsically safe circuits, and do not work with equipment that poses an
ignition hazard.
Potential Compen-
sation Connection
The connection to the local potential compensation point must be made before all
other connections.
Risks of a
Disconnected
Protective Lead
The EL6010 gas analyzer can be hazardous if potential compensation is inter-
rupted inside or outside the gas analyzer or if the potential compensation connec-
tion is interrupted.
Risks Involved in
Opening the Covers
Current-bearing components can be exposed when covers or parts are removed,
even if this can be done without tools. Current can be present at some connection
points.
Risks Involved in
Working with an
Open EL6010 Gas
Analyzer
The EL6010 gas analyzer must be disconnected from all power sources before
being opened for any work. All work on an gas analyzer that is open and con-
nected to power should only be performed by trained personnel who are familiar
with the risks involved.
While connected to power, the EL6010 gas analyzer housing should only be
opened when the surrounding environment does not pose an explosion threat.
Charged Capacitors The EL6010-... analyzer unit capacitors require 10 minutes to discharge after the
system is disconnected from all power sources. Observe the safety precautions
indicated on the housing.
In the capacitors of the EL6010-CU control unit dangerous energies can be stored
even after separation from the voltage source. The control unit housing must not
be opened if the surrounding atmosphere is an explosion risk. Observe the
warning advice on the housing cover on this subject.
Sample Gas Supply
Cutoff
When working with flammable and toxic sample gases, shut off the sample gas
supply and purge the sample gas path with nitrogen before opening the EL6010-...
analyzer unit housing.
When Safe Operation
Can no Longer be
Assured
If it can be assumed that safe operation is no longer possible, the EL6010 gas
analyzer should be taken out of service and protected against inadvertent use.
The possibility of safe operation is excluded:
• If the gas analyzer is visibly damaged
• If the gas analyzer no longer operates
• After prolonged storage under adverse conditions
• After severe transport stresses

Gas Inlet and Outlet Conditions
Sample Gas
Inlet Conditions
(Atmospheric
Conditions)
The gas analyzer is capable of measuring non-flammable and flammable gases
under atmospheric conditions which occasionally can form an explosive environ-
ment.
Inlet Pressure p
e
≤ 100 hPa (= 0.1 bar) or p
abs
≤ 1,100 hPa (= 1.1 bar)

EL6010-Magnos106 20 to 60 l/h
EL6010-Caldos17 normally 10 to 90 l/h, min. 1 l/h
The maximum oxygen content of the sample gas mixture should be 21 Vol.-%,
corresponding to atmospheric conditions.
If the sample gas is a mixture only of oxygen and flammable gases and vapors, it
must not be explosive under any conditions. As a rule this can be achieved by
limiting the oxygen content to a maximum of 2 Vol.-%.
Flammable gases that are explosive under the conditions encountered in analysis
even when oxygen is excluded should be present in the mixture only in concentra-
tions that are not critical to safety.
Sample Gas
Inlet Conditions
(Positive Pressure)
When specially equipped and when special conditions are fulfilled, the gas ana-
lyzer is capable of measuring pressurized non-flammable and flammable gases.
The sample gas should never be explosive. The analyzer unit should have two
ventilation openings.
Inlet Pressure p

Sample Gas
Dew Point
The sample gas dew point should be at least 5 °C below the lowest ambient
temperature throughout the sample gas path. Otherwise a sample gas cooler or
condensate trap is required. Water vapor content variations cause volume errors.
Corrosive Gases The EL6010 gas analyzers must not be used for the measurement of corrosive
gases. Gases like chlorine (Cl
2
) and hydrogen chloride (e.g. wet HCl) as well as
gases or aerosols containing chlorine must be cooled or undergo prior absorption.
Gas Outlet Conditions The outlet pressure must not exceed the inlet pressure by more than the pressure
loss across the analyzer.

Special Safety
Measures for
Operation with
Positive Pressure in
the Sample Gas Path
A special version of the analyzer units is needed for operation with positive
pressure in the sample gas path. This version is identified by the words “Messgas-
druck siehe Besondere Bedingungen” [See Special Conditions for Sample Gas
Pressure] on the identification plate.
When operating with positive pressure in the sample gas path the following special
safety measures should be taken:
• To protect the pressure-tight housing, two additional vent openings (imple-
mented in the same manner as sample gas flame barriers) are incorporated.
Their internal and external openings must always remain open.
• If the positive pressure at the sample gas outlet and inlet is p
e
≤ 300 hPa
(p
abs
≤ 1,400 hPa), in a failure mode (e.g. if the sample gas line in the analyzer
bursts) this can lead to a sample gas flow from both sides. For this case, steps
must be taken to assure that the total sample gas flow on both sides cannot
exceed the maximum value of 100 l/h.
• To avoid the development of an explosive mixture in the sample gas path, the
latter must be flushed with an inert gas prior to introducing flammable gases.
EL6010-Uras14
The “Flowing Reference Gas” option is not available for the EL6010-Uras14
analyzer unit for operation with positive pressure in the sample gas path.
Pressure Sensor
Connection
• If the pressure sensor connection is routed to the outside, the plug must be
removed from the associated flame barrier (see Figure 2, Page 12) before
starting operation.
• The pressure sensor connection should not be joined with the sample gas path
when measuring flammable and corrosive gases.
Housing Purge Housing purge is used to avoid corrosion in corrosive environment or with
corrosive sample or associated gases.
To preserve atmospheric conditions in the pressure-tight housing, two types of
purge operation are possible:
• Limiting purge gas inlet and outlet pressure to a maximum positive pressure
p
e
≤ 100 hPa (p
abs
≤ 1,100 hPa).
• The purge gas is supplied without pressure at the inlet and is extracted from the
outlet (p
e
≥ –100 hPa).
The purge gas flow must be limited to 10 l/h in normal operation.
Clean instrument air from non-explosive areas or an inert gas must be used as
purge gas. The purge gas should not contain any sample gas components.
16 EL6010 Gas Analyzer in Category 2G Operator’s Manual 42/24-30 EN Rev. 1
Connect Electrical Lines – Safety Precautions
CAUTION!
Follow all applicable national safety regulations for the preparation and
operation of electrical devices as well as the following safety precautions!
Potential
Compensation
The external potential compensation connections of the control unit and the
analyzer unit must be connected to the local potential compensation point.
The connection to the local potential compensation point must be made
before all other connections. Minimum conductor section = 4 mm
2
.
The gas analyzer can be hazardous if the protective lead is interrupted inside
or outside the gas analyzer or if the protective lead is disconnected.
Securing
Electrical Lines
All electrical wiring, including the connections between the analyzer unit and
the control unit, must be firmly secured.
Shielded Lines Shielded lines must be routed through the metal wiring connectors. The
shield braid must be placed on the cable connectors.
Unused
Cable Connections
Only the manufacturer’s original equipment plugs should be used to close off
the threaded cable connections. Unused cable connectors must be closed
off with factory-provided plugs. Securely tighten the cap nuts on the unused
cable connectors (torque to 2.5 Nm).
Before the Power
Supply is Connected
Before the power supply is connected, make sure the power line voltage is in
the permissible range 85 to 250 VAC for operation of the gas analyzer.
