1. About this document
1.1. Aim / Scope
This document informs about the worldwide applicable Honeywell ® GasLab Q2 hereinafter called
short Q2. It is a real-time natural gas analyzer from the enCore instrument series and measures the
superior calorific value, Wobbe index and other parameters in natural gas and is designed for
operation in many potentially explosive atmospheres. GasLab Q2 covers a wide operating
temperature range, this allows the analyzer to be placed close to the process to obtain a short
response time.
Common applications are control and regulation of gas tubins, fiscal energy measurement and
analysis of gas mixtures. To do so the Q2 uses the configuration and analysis software enSuite.
(Software details see chapter 8 Configuration and analysis software enSuite).
Please note that only the software and hardware versions mentioned on the
cover page are described here.
This document is intended for trained personnel in the gas industry or process measuring sector.
It explains the basic instrument functions and describes the installation, commissioning, operation,
use and maintenance. In addition to the general specialist knowledge, this document enables safe
and efficient use of the GasLab Q2. To do so, you must have a good command of the documentation
language or use another translation of this manual.
The safety and warning instructions on the device are in English or French.
Depending on the area of activity, trained personnel are assumed to have various basic
skills; the pertinent details are contained in the relevant sections.
Selon le domaine d’activité, diverses compétences de base sont nécessaires. Les
informations correspondantes se trouvent dans les chapitres respectifs.

1.2. How to use this document
Honeywell recommends that all technical documentation is always kept to hand in the system. For
a comprehensive overall understanding of the measuring system, it is essential to read the manual
before starting work!
Safety and warning information (generally shown as in this example) must be read and
obeyed in all circumstances.
A lack of warning signs or information does not release you from your personal
responsibility for safety.
Les consignes de sécurité et les avertissements (habituellement représentés comme dans
cet exemple) doivent être lus et respectés dans tous les cas!
En cas de défaut de symbole d’avertissement ou de consigne, vous restez responsable de
votre propre sécurité!
The modular, standard design of our devices allows you to skip some sections of this document. To
gain knowledge in the various fields, for example, operation, it is also enough simply to read the
appropriate chapters after the safety instructions.
The first chapters of this document deals with the hardware. It contains the explosion-relevant
information as well as a summary of relevant safety and warning notices. In addition to general
expertise, it enables the Q2 to be handled safely and efficiently.
The chapters 7 and 8 (software) are addressed to measurement operator’s and explains the basic
functions of the measuring instrument and how to operate the Q2 in detail.
The chapters 9, 10 and 11 gives information for keeping Q2 permanent in measuring capability and
a summary of the technical data.
The illustrations and figures are designed to provide a visual depiction
of the topics covered. They may differ slightly from the actual design.
1.3. Symbols, abbreviations and definitions
Essentially the same symbols are used both on the device and in the documents to ensure clarity.
A comparison with other Honeywell documentation will highlight the alternative symbol (if there
is one). Texts which are preceded by a sign of this type must be followed to the letter.
To ensure greater differentiation between gas and electrical lines, the term “cable” is always used
in this documentation for electrical lines.
General safety rules and expertise for how to act in plants and in dealing with gas
are assumed to be known and are therefore not reproduced here in full.

Explanation/Definition
Administrator
Administrator is a person with unrestricted access to the device and res-
ponsible for setting and transferring user management to the device.
The Administrator should therefore have the appropriate equipment
knowledge e.g. by participating in a training course.
The station operator usually takes on this task.
Alarm
Error which jeopardizes the correctness of the results.
Generated, for example, if a measurement is outside the defined measuring
range.
The start and end of an alarm are registered with time stamps in the
associated logbook / error list.
Analysis
is the operating mode in which the device undertakes systematic analyses
and is therefore the normal operating state.
Approval file
is an enSuite file which automatically defines which parameters should be
especially protected. It contains approvals for specific countries or standard-
ized settings and relates to all relevant AFBs. An approval file must be used
for fiscal purposes, otherwise its use is optional.
Audit trail
is a two-part log archive (parameter audit trail) which enables the user to
conduct changes relevant to billing without opening the SSW.
These changes are monitored and documented in the fiscal section. If the
SSW is opened, data are only included in the general section.
Base calibration
is a factory adjustment of the device using multiple gases before delivery. It
may be repeated by Honeywell if necessary in adjustment procedures.
Breathing device
The breathing device (short breather), also known as venting device or flame
arrester, is designed to equalize the pressure on explosion-proof housings.
This pressure equalization device is required during operation and must not
be sealed.
C2+
means that all higher hydrocarbons are added to the ethane component.
Cable
To ensure greater differentiation between gas and electrical lines, electrical
lines are always referred to as “cables” in the following.
Calibration gas
See Operational calibration gas.
Carbon dioxide
(CO2)
An acidic, non-flammable, colorless and odorless gas comprising a chemical
compound of carbon and oxygen. The gas is also known as carbonic
anhydride or colloquially carbonic acid.
Checksum
is a method to identify, display and check the software version. It is
calculated by the device itself. Further information about this checking
method used by enCore devices is provided in the manual entitled “enCore

GasLab Q2
Term
Explanation/Definition
Compressibility
factor Z
The quotient from the actual (real) volume of a specified mass of gas at a
specified pressure and temperature and its volume as calculated from the
Ideal Gas Law (for the same pressure and temperature). The compressibility
factor Z is generally dependent on the temperature, pressure and gas
composition.
CSA mark
The mark shows that the product has been certified by an accredited third-
party lab (independent standards organization) and have met applicable
standards as required by American law.
DBB technology
is a valve technology to seal gas streams. The connection of 2 solenoid
valves in series, between which there is a vent, ensures that the system is
safe even if the valves leak.
Density/Density at
base conditions
is the quotient of the mass of a gas sample and its volume in specified
pressure and temperature conditions or at base conditions, e.g. in kg/m³.
The density or density at base conditions is used to monitor the gas
composition and energy content of fuel gases.
Display
is the generic term for all depictions and views on the computer and the
optional screen.
enCore devices
enCore is the name of the product platform for representatives of a range of
measuring devices based on similar modular hardware and software. Their
configuration is variable. In addition to the GasLab Q2, these include the
volume conversion device enCore ZM1, the signaling and monitoring unit
enCore MC1 and the flow computer enCore FC1.
enSuite
The configuration and analysis PC software for current Honeywell Elster
devices in the field of flow computer, data storage, gas quality analyzer and
ultrasonic gas meter. The software supports all activities that are required for
commissioning and maintenance of these devices.
Error list
is used by the user to identify errors and reproduce the history of the error.
The start and end of a message is entered into the error list with a time
stamp and recorded in the logbook.
Event
or note is generated if a measurement violates a state defined by the user.
The start is entered in the error list with a time stamp and logged in the
logbook. Notes cannot be accepted and are automatically deleted from the
error list after the cause of the note has ended.
Export value
(enSuite)
The function blocks in the software supply results which can be processed
by other function blocks. These results are known as export values.
Firmware
Firmware is software that is functionally fixed to device hardware
components. It is embedded or stored in the device and cannot be replaced
by the user.

GasLab Q2
Term
Explanation/Definition
Gas family
Classification of fuel gas types into groups based on their physical and
combustion properties (families, abbreviated to GF)
A distinction is made between 4 gas families. Gas families are classified in
Germany in DVGW Code of Practice G 260; natural gas and gas similar to
natural gas are members of the second gas family in this system.
Gas Quality
Analyzers
are devices which automatically measure the superior calorific value of
gases. The superior calorific value, density at base conditions and carbon
dioxide content are calculated using the values from the sensors.
Gas saturation
Reflects the influence of water vapor on calorific value/heat value.
Values for wet (saturated) gas or partly wet (partially saturated) gas are lower
than those for dry (unsaturated) gas because the total volume consists of
the components of hydrocarbons and water vapor.
The instrument do not analyze water vapor. The determination of the actual
water vapor content must, for example, be obtained from moisture or dew
point measurements.
The results are therefore calculated for three assumed standards (dry/wet
/partly wet) of water vapor.
Ground loop
Grounding the devices may create ground loops since the cable screens
create additional connections if they are connected to both sides.
A ground loop is electric cabling closed to create a loop. In the event of low-
frequency error currents, an undesirable voltage drop occurs in the signal
path and an interference signal is added to the signal as a result of the
impedance of the loop.
Grounding
Grounding is the general term used for the highly conductive connection to
a reference potential, for example, to the earth which is also conductive.
This device connection is used, among other things, to prevent incoming and
outgoing interference as described in the EMC directives and allows various
electrical devices and equipment to be operated with a joint reference
potential.
Inferior calorific
value
also called net heating value or Lower heating value Hi (colloquially known
as energy content or energy value) is a heat variable.
In contrast to the Superior calorific value, the calorific value, all the
combustion products are in gaseous which is why this value is lower than the
superior calorific value. The value can refer to mole, mass or volume, for
example in kWh/m³.
Location of use
See Place of Use.
Logbook
also known as the standard audit trail, is a log archive which can be used by
all software parts and records every extraordinary situation, for example,
errors in the measuring equipment.

Operating mode
Different working states of the device during operation are known as
operating modes.
Operational
calibration gas
also known as just calibration gas, is kept in a cylinder permanently
connected to the GasLab Q2 and is an integral part of the measurement
device. This is a mixture of methane and carbon dioxide with officially
defined properties and is required for automatic calibration.
Ordinal number
or sequence number is an automatically assigned identification number for
archived data. This is formed so that the very first archive entry has the
number 1. The number is incremented by one for each subsequent entry.
PELV
PELV protective extra-low voltage systems which comply with
DIN EN 60079-14: the power supply to generate PELVs must ensure that no
short-circuit is possible between the primary voltage and the extra-low
voltage and its connections. It has a safe electrical isolation point (safety
isolation transformer) and complies with IEC 61558-2-6.
The circuits are grounded.
All bodies of electrical equipment must be connected to a common
grounding (and equipotential bonding) system.
Pipeline
Pipeline is the 0.5 to >2 m diameter steel pipe. The instrument uses much
smaller diameters. The production and installation of tubing is entirely
different from pipelines.

Explanation/Definition
Power-limited
circuit
A power-limited circuit is a circuit separated from other circuits by at least
BASIC INSULATION in which the direct voltage (U) is no greater than 60 V.
The current which can occur in the circuit is limited by certain measures to a
value of less than 200/U. These measures must interrupt the circuit within
120 seconds if this value is exceeded.
Process gas.
is the gas which is to be analyzed or measured. It is supplied to the
measuring equipment in normal operation and is also known as the
operating sample gas
Reference
potential
is a potential to which all other voltages are referred. The potential of a
grounded point (ground potential) is used for this purpose and gives it a
value of zero volts.
Since ground connections, like all connections, have different resistances,
voltage differences or potential differences may occur between grounded
points and system parts. A correctly designed low resistance equipotential
bonding cable between the system parts or devices can eliminate these
ground potential differences.
Security switch
(SSW)
(also known as the CAL switch) is a possible hardware isolator and part of the
concept to limit user rights. Since a change requires the housing to be
opened, this may only be done by trained personnel with the authorization of
the manufacturer.
SELV
SELV safety extra-low voltage systems which comply with DIN EN 60079-14:
The power supply to generate SELVs must ensure that no short-circuit is
possible between the primary voltage and the extra-low voltage and its
connections. It has a safe electrical isolation point (safety isolation
transformer) and complies with IEC 61558-2-6.
Live parts of circuits must not be grounded or connected to live parts or PE
wires of other circuits. All bodies of electrical equipment cannot be grounded
(for example, for electromagnetic compatibility).
(GasLab Q2 must be grounded even in a SELV system)
Signal
is an event which is only output for a short time.
Acceptance by the user is not required.
Signals are also entered into the logbook.
Software
also called application software, is a collective term for programs that
determine the function of a device. It can be exchanged or updated by the
user.
Specialist
or professional is the designation for a trained person who, as a result of
their technical training, possesses skills and experience and who is familiar
with the relevant standards and regulations. Trained personnel can assess
their work and identify potential dangers.
Hardware work on the GasLab Q2 requires, among others, the expertise
described in EN/IEC 60079-14, Annex A.
