Magnetically Operated Front Panel
Magnetically Operated Front Panel
Persons with cardiac pacemakers should absolutely avoid magnetic
fields !
Negative effects on persons beyond those described above caused by
magnetic fields are not known. It is presumed that persons showing allergic
reaction on contact with ceramic or metallic material show the same
behavior on contact with magnetic material.
Instruction Manual
HASAxE-IM-HS

DANGER TO LIFE
Permanent magnets are surrounded by magnetic fields. These magnetic
fields can disturb and even destroy sensitive electronic measuring devices,
but also mechanical watches, credit cards, etc.
Usually a distance of 20 inch (0.5 m) is enough to avoid damages. All sintered
permanent magnets are hard and brittle. Hitting of sintered permanent
magnets by the magnetic attraction causes splitting into fragments with many
sharp edges. This especially occurs with high energy magnets, and can
also cause skin bruises by high attraction.
High energy magnets made of rare-earth materials have to be stored dry,
otherwise the surfaces would oxidise. Unprotected operation in a humid
environment may cause corrosion. Avoid damaging the protective galvanic
coating.
A storage in a hydrogen atmosphere destroys these magnet s. A demagnetisation is caused when permanent magnet materials have been exposed in
a radioactive radiation for a long time.
For air transportation of magnetic material the IATA instructions have to be
observed:
Magnetic fields are not allowed to penetrate the package, if necessary the
magnets have to be shorted using a metal plate.

1-1 Overview
The X-STREAM series analyzers offer a wide
range of available configurations and options,
to be combined according to the selected
model:
Measuring principles
Up to two out of all offered principles may be
combined within one analyzer model to provide
best adaption to the application.
For a detailled description of available
measuring principles: chapter 3.
Gas path design
Internal tubing with viton or, optional and
depending on application, PFA or stainless
steel.
In addition one or more of the following options
are available:
• Soleniod valve block
This option uses 4 internal solenoid valves
to control sample, zero, span gas 1 and
span gas 2. These gases are fed to the
analyzers to provide manual or controlled
automatic calibration (initialized by
keypad, serial interface or digital inputs).
• Sample pump
Maximum flow rate 2.5 l/min
• Barometric Pressure sensor
(Measuring range 800 to 1,200 hPa)
Facilitates compensation of atmospheric
pressure variations to improve precision
of results (
measurement specifications, page 3-17).
Special sensors for e.g. corrosive gas on
request.
• Flow measurement
A flow sensor (option) can be used to
monitor gas flow and set alarms.
• Heated box for physical components
All the physical components
*)
can
optionally be installed inside thermostatted
box to minimize influences from ambient
tem-perature fluctuations.
For a detailled description of optional gas path
components: page 1-18
Interfaces
All models may be configured to use several
interfaces:
St andard:
• analog outputs
• serial interface (RS 485 or RS 232) with
Modbus protocol
• status signals (NAMUR; relay outputs)
Optional:
• 8 digital outputs & 7 digital inputs
• Modbus via Ethernet

Tabletop or Rack Mount Version
Instruction Manual
HASAxE-IM-HS
1 1/2006
This basic general purpose version contains
all components within a full 19 inch housing and
is intended to either be used as rack mountable
analyzer or as tabletop instrument after removing
two mounting brackets and installing 4 feet (part
of an accessory kit).
The front panel shows a 4x20 characters alphanumeric display, a membrane keypad and
3 status LEDs (fig. 1-1).
Electrical connections are provided by either
screw terminals (version GP , fig. 1-2) or plugs,
sockets and mains appliance (version GPS,
fig. 1-3) at the instrument's rear side.
Gas fittings are provided at the instrument's
rear side, too.
An optional fitting facilitates purging the
instrument with inert gas to minimize influences
caused by ambient air when measuring low
ranges of select gases (e.g. CO, CO
). The in-
2
ert gas may exhaust the analyzer through a
separate fitting (into an exhaust system) or
by leakages in the housing (into ambient).
Purging the physical components with air or
inert gas may also be needed when measuring aggressive and/or flammable gases: In
addition to the purge fitting an internal box is
installed, covering the physical components.
This forces the purge medium to flow around
all other (electronic) components before it
circulates around the physics and exhausts
the analyzer through a separate outlet fitting
into an exhaust system. In case of internal
leakage this ensures that the aggressive/
flammable gas is not flushed towards the
electronics causing hazards of corrosion and/
or explosion and provides operator safety .

inert gas may exhaust the analyzer through a
separate fitting (into an exhaust system) or by
leakages in the housing (into ambient).
Purging the physical components with air or
inert gas may also be needed when measuring aggressive and/or flammable gases: In
addition to the purge fitting an internal box is
installed, covering the physical components.
This forces the purge medium to flow around
all other (electronic) components before it
circulates around the physics and exhausts the
analyzer through a separate outlet fitting into
an exhaust system. In case of internal leakage
this ensures that the aggressive/flammable
gas is not flushed towards the electronics
causing hazards of corrosion and/or explosion
and provides operator safety .
Purge medium specifications:
see technical data section (2-1).
An optional fitting facilitates purging the
instrument with inert gas to minimize influences
caused by ambient air when measuring low

1-4 X-STREAM FD
1-4 X-STREAM FD Cast Field Housing
X-STREAM
X-STREAM FD analyzers, providing agency
certified flame-proof protection are intended to
be installed in hazardous areas. The wall
mountable cast aluminum enclosure with it´s
rugged design and a NEMA 4X / IP66 protection also provides advantages when installed
in non-hazardous, but harsh environments.
The front panel is located behind a safety glass
providing protection against mechanical impact
and shows a 4x20 characters alphanumeric
display and 3 status LEDs. The keypad as it is
used to operate the tabletop analyzer is replaced by sensor fields, operated with a magnetic tool (Abb. 1-9).
Electrical connections are provided by internal
screw terminals, the cables enter the housing
via cable glands or conduits located at the
instruments bottom side (Abb. 1-1 1).
Gas fittings are located at the instrument's
bottom side, too.
The enclosure consists of two parts, secured
together by means of 20 screws, located on a
flange at the instrument´s outside. The front
cover opens vertically by 180° providing easy
access to internal components.
Some gas fittings may optionally be used for
purging the instrument with
• Inert gas to minimize influences caused by
ambient air when measuring low ranges
of select gases (e.g. CO, CO2)
or
• Air or inert gas when measuring aggressive and/or flammable gases: In addition
to the purge fitting an internal box is
installed, covering the physical components. This forces the purge medium to flow
around all other (electronic) components
before it circulates around the physics and
exhausts the analyzer through a separate
outlet fitting into an exhaust system. In case
of internal leakage this ensures that the
aggressive/flammable gas is not flushed
towards the electronics causing hazards
of corrosion and/or explosion and provides
operator safety .

• internal sample gas pump
• internal valve block
• internal flow monitor
• internal barometric pressure sensor
X-STREAM
1-6-1 Internal Sample Gas Pump
An optional sample gas pump may be required
if the process gas stream is without exerting
pressure. In this case the pump ensures the
sample gas stream through the instrument
remains constant.
If an internal sample gas pump is installed, the
associated software setup menu entry shows
Y es (
5-4-3-5, page 5-41). The valve may
be controlled either manually by a corresponding menu line or remotely by a digital input.
1-6-2 Internal Valve Block
An optional internal valve block allows to
directly connect sample gas as well as span
and zero calibration gases to the instrument,
e.g. enabling automatic calibration.
If an internal valve block is installed, the associated software setup menu entry shows
Internal or Int+Ext ( 5-4-3-5, page 5-41).
V alve control is supported by a corresponding
menu line, by selecting the autocal mode or
remotely by digital inputs.
1-6-3 Internal Flow Monitor
An optional internal flow meter allows to
monitor the gas flow and set an alarm in case
of a fault.
If an internal flow monitor is installed, the associated software setup menu entry shows Yes
(
5-4-3-5, page 5-41).
There will be a status message in the measuring screen if the gas flow is too low and the
related "Check requests" menu entry is Yes
( chapter 8 "Troubleshooting").
1-6-4 Internal Barometric Pressure Sensor
An optional internal barometric pressure
sensor allows to compensate the influence of
changing ambient pressure on the measuring

1-6 Optional Gas Path Components
1-6-5 Optional Heated Compartment
Instruction Manual
HASAxE-IM-HS
1 1/2006
Two optional internal heated compartments
offer three functionalities:
At first the compartments allow to heat all
physical components at 60° C to avoid
condensation of gases inside the gas path and/
or reduce influence of ambient temperature
fluctuation.
In addition to thermostating the physical components this box can be purged and thus allows
to keep out ambient air, interfering measuring
gases at low ranges. The purge medium is
applied to a separate fitting, passes the
electronics, enters the box and exits through
leaks into ambient.
An alternative, gastight compartment allows to
measure corrosive and toxic gases protecting
the electronics and providing operator safety .
With this box the purge medium when applied
to the separate inlet fitting flows through the
electronics, enters the box to flow around the
physical components and than exits through a
purge gas outlet, recommended to be
connected to an exhaust.

LOW: Uin < 1.5 V
HIGH: Uin > 4.5 V
Input resistance: 57.5 kΩ
(V oltages to be measured against the reference
terminal labeled "IN GND").
Inputs protected against overvoltage up to
approx. 40 V . Open inputs are at LOW level.
See Chapter 7 Maintenance, section 7-3
Calibration procedures for a detailled description of how to drive the digital inputs In1 to IN3.
1-8-3-2 Digital Inputs IN4 to IN7
IN4 to IN7 are used to control valves. Signal
voltages at these inputs are evaluated in
decreasing order of priority: IN4 is assigned
the highest, IN7 the lowest prioritiy .
IN4 to IN6: A valve is opened by applying a HIGH
level signal voltage to the related input while all
inputs of higher priority are at LOW level. All
other valves are closed at the same moment,
regardless of the signal voltages applied to
inputs of lower priorities.
Input IN7 has a converted input logic:
The related sample gas valve opens by
applying a LOW level signal; a HIGH level signal
closes ALL valves.

Measuring Principles
X-STREAM
series analyzers support several
measuring principles or combinations of
principles, depending on measured gas
components. This provides best possible
results as the principle always is adjusted to
meet the specific characteristics of the
particular gas.
The following sections introduce the available
measuring principles and show their specific
characteristics.
3-1 Infrared Measurement (IR)
Ultraviolet Measurement (UV)
This principles make use of infrared/ultraviolet
light absorbed by the sample gas. The wave
length of the absorbed portion of IR/UV light
characterizes the gas component whereas the
intensity of absorption is a measure of
concentration.
Two different IR measuring principles are
available, both comparing concentration
depend and concentration independ signals.
The difference of these two signals results in a
measure of concentration.
One of these principles (as described in detail
in the following sections) is adapted for UV
measurements: The absorption measurement
in the UV spectral range is based on the same
principle as the IR measurement, but a glowdischarge source is used instead of an IR
source.
As the glow-discharge source needs a specific
and as constant as possible temperature, it is
either thermostatted to about 55 °C or built into
a thermostatted box, covering all physical
components and completely thermostatted.
Section 3-1-2 covers both IR and UV measurement.
The decision about which measurement (UV
or IR) is selected for a specific application
depends on the gas component to be
measured. The decision about which IR
measurement to be used is based on the
required performance.
3-1-1 Interference Filter Correlation (IFC)
This is an IR principle only and suitable for
applications not requiring high performance
parameters.
An undivided analysis cell is alternately passed
by light of two different wave lengths, filtered
by interference filter out of the spectrum of an
IR source: One wavelength covers the
absorption band of the measured gas
component, the other is selected to cover a
region where no absorption occures.
Fig. 3-1 shows an example of interference filter
transmissions and absorption bands of the gas
components CO and CO
. It‘s easy to see that
2
the interference filters‘ transmissible spectral
bands overlap the absorption bands of the
gases, whereas within the bandwidth of the
reference filter no absorptin takes place. Other
gases (CH4) and HC do not affect the measuring result because they do not absorb IR light
of these wavelengths.

A pyroelectrical detector generates a signal
using the effect of charge flow caused by heat
flow within a piezo crystal:
The IR radiation passing measuring cell and
filters results in a change of temperature when
arriving at the detector. The IR absorption is
different for measuring wavelength and
reference wavelength so the crystal is
alternately more or less heated. As result the
detector gives an alternating voltage signal
which is passed to electronics for further
processing.

3-1 Infrared (IR) and Ultraviolet (UV) Measurement
3-1-2 Opto Pneumatic Measuring Principle
X-STREAM
This high performance principle is used for IR
and UV measurements and utilizes a separated
analysis cell whose one side is passed by the
sample gas. The other side (reference side) is
either filled with an inert gas (e.g. nitrogen) or
passed by a reference gas stream, depending
on application.
Both sides of the cell are alternately irradiated
with IR (UV) light of same intensity, which
afterwards passes a filtering cell before it
arrives at the detector.
absorption chamber
The opto pneumatical detector, which is used
instead of the pyroelectrical detector with the
IFC principle, converts the radiation from sample side and reference side into a voltage
signal proportional to the radiation intensity .
The pneumatical detector consists of a gas
filled absorption chamber and a compensation
chamber, both connected by a flow channel. A
micro flow detector is placed within this channel
to measure least flows.

3-1 Infrared (IR) and Ultraviolet (UV) Measurement
3-1-3 Technical Implementation
The detector is filled with the gas to be
measured and therefore sensitive to the related
characteristic wavelength band only .
The absorption chamber is sealed with a
window transparent for IR radiation [CaF
(Calziumfluorid)] .
There is no absorption when the IR(UV)
radiation passes the reference side of the
analysis cell , so the intensityis at a maximum
when it arrives at the detector. The gas within
the detector is heated, therefore expands and
flows from absorption chamber through flow
channel to the compensation chamber. This
flow generates a voltage signal.
When the IR(UV) radiation passes the sample
side of the analysis cell, part of it is absorbed
by the sample gas decreasing the radiation
intensity . As an effect the gas within the detector
cools down and flows from the compensatoin
chamber back into the absorption chamber.
This flow again causes a voltage signal by the
micro flow detector which is now reverse to the
previous signal.
So the micro flow detector generates alternating signals. The flow channel is designed to
not influence the gas flow and therefore the
change in signal is proportional to the change
in radiation intensity which is proportional to
the concentration of gas to be measured.
The broadband IR (UV) radiation emitted by a
special source passes a chopper wheel (fig.
3-3 showing a dual channel analyzer). In case
of IFC principle it passes additional optical
filters, before entering the analysis cell. The
2
radiation leaving the cell is focused to the
detector by means of a filter cell. The detector
output signal is passed to micro processor
controlled electronics conditioning and
converting it to reasonable units (V ol-%, ppm,
mg/m³, etc.) shown on the alphanumeric
display.
Depending on gas component and measuring
range several photometer designs are used
with X-STREAM series analyzers, differing in
analysis cell length, kind of detector and used
filters. Optionally the assemby may be sealed
against ambience: O-rings between the
components prevent ambient air to come in the
optical path and interfere the measurement.
The photometer assembly is mounted on the
BKS main board, which itself is placed in
housings rail.
The flow detector signal is passed to electronics conditioning the signal and converting
it into a usefull format.

Fig. 3-4 shows the mechanical design of an
pyro detector assembly:
Attached to the chopper are IR source (07) as
well as analysis cell (09) with signal detector
unit (filter cell 14 / 15) and pyroelectrical
detector with integrated pre amplifier (16).
Furthermore the chopper assembly contains
the filter aperture (04 / 05) limiting the IR light
to the required bandwidth.
The chopper assembly (03) is made of two
parts and contains an inner volume where the
stepper motor driven chopper wheel is placed.
This inner volume is sealed against ambience
by means of an o-ring to prevent ambient CO
from entering. This avoids pre absorption and
drift. An additional absorber is used to remove
CO2 traces existent by diffusion.
Furthermore the chopper assembly contains a
light barrier to detect the chopper wheel
phasing. A temperature sensor (28) measures
the assemblies‘ temperature. This information
is used for the purpose of compensating
temperature effects.
The filter cell (14 / 15) is made as two-tiered
conus system, which is optimized to focus the
beam to the active detector area.
High measuring ranges (up to 100 %) require
an adaptor cell (10): The analysis cell is in this
case the volume between output window of the
adaptor cell and input window of the filter cell ,
covered by a distance ring (08).
2
The analysis cell is made of an aluminum tube
with two gas fittings. This simple design without
windows easily allows cleaning if the cell is
polluted.
The chopper windows and those at the filter
cell remain as only possibly polluted windows.
All of them are accessible once the analysis
cell is removed.

3-2 Oxygen Measurement
X-STREAM
3-2 Oxygen Measurement
Two dif ferent principles are used for measuring
oxygen concentrations. The currently used
principle is given by the channel code (sample
gas designator) on the nameplate label (
fig 2-7, page 2-16):
pO2 = paramagnetical sensor
eO2 = electrochemical sensor
3-2-1 Paramagnetic Measurement
Oxygen measurement is based on the paramagnetical characteristics of oxygen molecules:
Two nitrogen filled quartz spheres (N2 is not
paramagnetic) are arranged in a dumbbell
configuration and, hinged to a platinum wire,
placed inside a cell. Fixed to the wire a small
mirror reflects a light beam to a photo detector
(fig. 3-6).
The measuring cell is placed inside an
inhomogeneous magnetical field generated by
a strong permanent magnet of specific design.
So the current compensating the torque affecting the dumbbell is a direct measure for the
oxygen concentration within the sample gas.
In addition to measuring cell, permanent
magnet, electronics and enclosure the paramagnetic oxygen detector contains a temperature sensor and a heating element to hold the
detector at approx. 55 °C.
Several variations are available including
corrosion resistant, solvent resistant and/or
intrinsically safe (for measuring flammable
gases) versions.
3 Principles
Oxygen molecules within the sample gas now
due to their paramagnetical characteristics are
deflected into the area of highest field strength.
This generates different forces on both spheres
and the resulting torque turns dumbbell and
mirror out of the rest position. This generates
a photodetector signal because the beam is
deflected, too.
Initiated by the photodetector signal a preamplifier drives a compensation current through
a loop surrounding the dumbbell to turn back
the dumbbell into the rest position by effect of
a magnetic field

The temperature compensating thermistor and
adjusting resistance are connected between

the cathode and anode. The current generated
by oxygen reduction is converted into a voltage
by these resistances.
The value of the current flowing to the thermistor
and resistance varies in proportion to the
oxygen concentration of the measuring gases
which contact the membrane. Therefore, the
voltage at the terminal of the resistances is
used for the sensor output to measure the
oxygen concentration.

In consequence of it‘s design the sensor‘s
lifetime is limited and depends on theoretical
designed life and oxygen concentration. The
sensor output can be taken as a rough criterion
for end of lifetime: The sensor is weared when
the output in atmosphere is below 70 % of the
initial output. The period till this can be
calculated by
Lifetime =
designed life (hours)
O2 concentration (%)
The sensor‘s designed life under constant
conditions of 20 °C is approx. 900,000 hrs.
The lifetime at 21 % oxygen is then calculated
to approx. 42,857 hrs, corresponding to
approx. 5 years.
3-12
Note!
The given values are for reference only! The
expected lifetime is greatly affected by the
temperature of the environment in which the
sensor is used or stored. Increases or
decreases in atmospheric pressure have the
same effect as that by increases or decreases
in oxygen concentration (Operation at 40 °C
halves lifetime).

constant.
For correct measurement the cell needs continuously to be supplied with concentrations of at
least 0.1 Vol.-% O2 . We recommend to use
the cells if need be in alternating mode, means
to purge cells with conditioned (not dried, but
dust removed) ambient air when measurement
pauses.
If it is necessary to interrupt oxygen supply for
several hours or days, the cell has to regenerate
(supply cell for about one day with ambient air).
Temporary flushing with nitrogen (N2) for less
than 1 h (e.g. for analyzer zeroing purpose) has
no influence on measuring characteristics.
This sensor is not suitable for anorganic gases
containing chlorene or flourene!
In addition is not suitable for sample gases
containing ozone, H2S (> 100 ppm) or
NH3 (> 20 ppm).

Thermal Conductivity Measurement primarily
is used for measuring concentrations of
hydrogen (H
) and helium (He). These gases
2
are characterized by their specific thermal
conducitivity , differing clearly from that of other
gases (see table 3-5).
3-3-1 Principle of Operation
A Wheatstone bridge, made of 4 temperature
sensitive resistors (PT 100 sensors), is
surrounded by gas in a way that each 2 sensors
are located in the measuring gas stream (RM)
and in a reference gas stream (RR), see fig. 2-9.
The bridge output signal (Ubr) is adjusted to zero
when in rest position (no gas flow).
By default the reference gas path is closed (not
flown through by gas). When sample gas is
supplied the sensors in the measuring gas path
are cooled due to the thermal conductivity
effect: The gas absorbs heat and carries it away
from the sensors. This tunes the Wheatstone
bridge and generates a signal proportional to
the thermal conductivity .
Additional electronics linearizes and conditions
this signal to provide usefull measuring values.

Thermal Conductivities

Depending on application it is possible to
supply a reference gas to the bridge‘s reference
side. The output signal in this case is proportional to the difference of the thermal
conductivities of sample and reference gas.

Chapter 4
Installation
This chapter describes how to install the different analyzer models in a safe manner and
gives instructions on what to care about.
4-1 Abstract Carefully examine the shipping carton and contents for signs of damage.
Immediately notify the shipping carrier if the carton or its contents are damaged.
Retain the carton and packing material until the instrument is operational.
ELECTRICAL SHOCK HAZARD!
Prior to connecting the analyzer to power ensure all safety instructions
as given in the appropriate chapter at the beginning of this manual and
in the following analyzer refered sections are read and unterstood!
Installation area has to be clean, free from
moisture, excessive vibration and frostprotected. T ake care to meet the permissible
ambient temperatures as given in the technical data section!
Instruments must not be exposed to direct
sunlight nor sources of heat.
4 Installation
For outdoor installation it is recommended
to mount the instruments into a cabinet. At
least sheltering against rain is recommended.

4-1 Installation - Abstract
To stay in compliance with regulations regarding electromagnetic compatibility it is recommended to use only shielded cables, as
optionally available from Emerson Process
Management or equivalent. Customer has to
take care that the shield is connected in proper way . Shield and signal connector enclosure
need to be conductively connected, submin-dplugs and sockets must be screwed on the
analyzer.
4-2 Gas Conditioning
To ensure trouble-free analyzer operation
one has to attach great importance to gas
conditioning:
All gases must be conditioned
before supplying!
When supplying corrosive
gases ensure that gas path
components are not affected!
Flammable gases must not
supplied without additional
protective measures!
It is prohibited to supply explosive gases!
Using external submin-d-to-terminal adaptor
elements (option) affects electromagnetic
compatibility . In this case the customer has to
take measures to stay in compliance and has
to declare conformity , when required by legislation (e.g. European EMC Directive).
Furthermore the gases must be
- dry
- free of dust
- free of aggressive components affecting
gas path materials (e.g. by corrosion).
If moisture can not be avoided take care that
the gas‘ dew point is at least 18 F (10 °C) below
ambient temperature to avoid condensation
within the gas path.
The fieldhousing version X-STREAM F offers
the option to be ordered with thermostat
controlled pipes allowing a maximum dew point
of 77 °F (25 °C).
Pressure and flow must be within the limits given
by the measurement specifications table 3-7
(
3-4, page 3-17).
4-2
Emerson Process Management GmbH & Co. OHG
Instruction Manual
HASAxE-IM-HS
1 1/2006
Take care that all external gas lines are connected as described and are
tight to avoid leaks!
Improperly connected gas lines may cause explosion or death!
Exhaust may contain hydrocarbon and other toxic components (e.g. carbon
monoxide)! Carbon monoxide is highly toxic and can cause headache,
nausea, loss of consciousness, and death. Avoid inhalation of exhaust!
X-STREAM
4-2 Installation - Gas Conditioning
TOXIC GAS HAZARDS
Do not interchange gas inlet and outlet! All gases must be conditioned before
supplying! When supplying corrosive gases ensure that gas path components
are not affected!
Max. permissible gas pressure: 21.7 psi (1,500 hPa), except instruments with
integrated valve blocks (7.25 psi; 500 hPa) and/or paramagnetic oxygen sensor
(
table 3-7, page 3-17)!
Exhaust lines must be installed in a descending way, need to be pressureless,
frost-protected and in compliance with applicable legislative requirements!
The number of gas fittings as well as their
assignment vary depending on analyzer model
and selected options.
All gas fittings are labeled and are located at
• the analyzer's rear panel (X-STREAM GP ,
GPS)
• the analyzer's bottom side (X-STREAM F ,
FD)
4 Installation
When it is necessary to open gas paths seal
the analyzer‘s gas fittings using PVC caps to
avoid pollution of the internal gas path by
moisture, dust, etc.

sample source to minimize sample transport
time. A sample pump may be used to decrease
response time, whereat the analyzer is either

4-3 Installation - Electrical Connections
4-3 Electrical Connections
Installation and connecting power and signal cables are subject to qualified
personnel only taking into account all applicable standards and legislative
requirements!
Failure to follow may cause warranty invalidation, property damage and/or
personal injury or death!
Installation of these instruments is subject to qualified personnel only,
familiar with the resulting potential risks! Instruments providing screw
terminals for electrical connections may require working near live part!
X-STREAM
ELECTRICAL SHOCK HAZARD!
4 Installation
X-STREAM gas analyzers do not provide a power switch!
For X-STREAM F analyzers a power switch or circuit breaker (complying
with IEC 60947-1/-3) has to be provided in the building installation. This switch
has to be installed near by analyzer , must be easily operator accessible and
has to be assigned as disconnector for the analyzer.
Disconnect instruments with screw terminals from power when working at
power terminals (pull power plug or operate power switch/ circuit breaker in
building installation)!
The analyzers provide a protective earth terminal. T o prevent electrical shock
hazards the instruments must be connected to a protective earth. Therefore
the instruments must be connected to power by using a three wire power
cable with earth conductor!
Any interruption of the earth connector inside or outside the instrument or
disconnecting the earth terminal may cause potential electrical shock
hazzard!
The analyzers do not provide a power switch and are operable when connected to power.
