Special Safety Instructions for Operating Explosion-Protected
Analyzer Modules
Observe Safety
Precautions
Before starting any work on the Ex analyzer module, 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 Ex analyzer module can be hazardous if potential compensation is interrupted
inside or outside the Ex analyzer module 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
Ex Analyzer Module
The Ex analyzer module must be disconnected from all power sources before
being opened for any work. All work on an Ex analyzer module that is open and
connected to power should only be performed by trained personnel who are
familiar with the risks involved.
While connected to power, the Ex analyzer module housing should only be opened
when the surrounding environment does not pose an explosion threat.
Charged Capacitors The Ex analyzer module power supply capacitors require 10 minutes to discharge
after the system is disconnected from all power sources. Observe the safety
precautions indicated on the housing.
Sample Gas Supply
Cutoff
When working with combustible sample gases, shut off the gas supply before
opening the Ex analyzer module housing.
When Safe Operation
Can no Longer be
Assured
If it can be assumed that safe operation is no longer possible, the Ex analyzer
module should be taken out of service and protected against inadvertent use.
The possibility of safe operation is excluded:
•If the Ex analyzer module is visibly damaged
•If the Ex analyzer module no longer operates
•After prolonged storage under adverse conditions
•After severe transport stresses

Gas Connection
Design
(see Figure 1)
All gas connections –with 1/8-NPT female threads –are routed via flame barriers:
•Sample Gas Inlets and Outlets
•Housing Purge (Option)
•Flowing reference gas for the Uras 14-Ex (Option)
•Pressure sensor for Uras 14-Ex, Magnos 106-Ex (Option) and Caldos 17-Ex
The actual gas connection layout of a delivered Ex analyzer module will be shown
in the applicable analyzer data sheet.
Sample Gas Inlet
Conditions
see “Operating Specifications”section, page 30
CAUTION!
The sample gas must not contain corrosive gases (such as chlorine) that
attack stainless steel.
Special Safety
Measures for
Operation with
Positive Pressure in
the Sample Gas Path
A special version of the Ex analyzer modules 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 (implemented
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 pe< 300 hPa (pabs <
1400 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 combustible gases.
Uras 14-Ex The "Flowing Reference Gas" option is not available for the Uras 14-Ex analyzer
module for operation with positive pressure in the sample gas path.

Connect the Gas Lines, continued
Housing Purge 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
pe≤100 hPa (pabs ≤1100 hPa).
•The purge gas is supplied without pressure at the inlet and is extracted from the
outlet.
During operation, purge gas flow should be limited to 10 liters/hour.
Clean instrument air from non-explosive areas or an inert gas is to be used as the
purge gas.
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 1, Page 8) before starting
operation.
•The pressure sensor connection should not be joined with the sample gas path.
Gas Path Seal
Integrity Verification
The seal integrity of the sample gas path and reference gas path (if applicable)
within the Ex analyzer module is factory-tested with helium at a leak rate of
< 2 x 10–4hPa l/s.
Since gas path seal integrity can be compromised during shipping of the Ex
analyzer module (e.g. by strong vibration) a seal integrity check should be
performed on site prior to startup (see "Check Gas Path Seal Integrity, Page 11).
FFor more information on checking gas path seal integrity during operation see the
"Inspection and Maintenance" section (Page 27).

42/24-12-2 EN Advance Optima Ex Analyzer Modules Operator’s Manual 11
Check Gas Path Seal Integrity
Quantity Description
1 Pressure gauge
1 Tubing, approx. 1 meter in length
1 Tee with shutoff valve
Material Required
Air or nitrogen
CAUTION!
If the seal test is to be carried out with air and there is the possibility of a
combustible gas being present in the gas paths or if a combustible gas is to
be introduced later, the gas paths should first be purged with nitrogen. Other-
wise the seal integrity test can be performed with nitrogen.
Step Action
1 Plug the outlet of the gas path to be tested.
2 Connect a hose with a tee fitted with a shutoff valve to the inlet of the
gas path to be tested.
3 Connect the free end of the tee to the pressure gauge.
4 Blow air or nitrogen through the shutoff valve until the sample gas path
is pressurized to a peof approx. 50 hPa (= 50 mbar). Close the shutoff
valve. Maximum excess pressure pe= 150 hPa (= 150 mbar).
5 The pressure should not change measurably in 3 minutes. A sharp
pressure drop is a sign of a leak in the gas path being tested.
Gas Path Seal Integrity
Verification
6 Repeat steps 1-5 for all gas paths in the analyzer module.

Isolation Relay -K01 Isolation relay -K01 is installed in the CU-Ex. It is used to connect the system bus
cable HIGH, LOW and GROUND leads and the non-intrinsically safe system
controller signal leads.
The standard arrangement of isolation relay -K01 is shown in the CU-Ex Operator’s
Manual (Publication No. 42/24-13 EN).
Terminal Strip -K05 Terminal strip -K05 is installed in the CU-Ex. It is used to connect the 8-wire
system bus cable leads not connected to isolation relay -K01.
Terminal strip -K05 is not needed if the 8-wire Ex analyzer module system bus
cable is routed to a connection box and a 3-wire extension cable is used for the
connection to the CU-Ex.
Terminal Strip -K06 Terminal strip -K06 is installed as an option in the central unit version for use in
Zone 2 and in the non-explosion protected version. It is used for system bus cable
connections.
If terminal strip -K06 is not installed, the Ex analyzer module system bus cable
should be routed to a connection box and the connection to the central unit
should be made via the standard system bus cable with plug and a tee.
Power Line Filter -Z01 The Ex analyzer module 24-VDC connecting cable can only be connected directly
to the (Ex) central unit if the optional -Z01 power line filter is installed.
If the -Z01 power line filter is not installed, the 24-VDC cable is connected to a
separate power supply.
