Series Laser
is used in a manner not specified within
this manual, the protection provided by the equipment may be
impaired.
Failure to observe the requirements of the manual may result in the
user being held responsible for the consequences and may
invalidate any warranty.
Before you attempt to install, commission or use the
07931
-
Series
Laser, read this manual carefully.
Do not attempt to install, commission, maintain or use the
07931
-
Series Laser unless you are trained and competent.
The
07931
-
Series Laser
doe
s not
include any user
-
serviceable
parts.
The
07931
-
Series Laser
does not include any user replaceable
fuses.
Do not use the
07931
-
Series Laser
as Personal Protective
Equipment (PPE).
If you do not install an
d use the
07931
-
Series Laser
in accordance
with the instructions in this manual, you may risk exposure to
hazardous laser radiation.
The
07931
-
Series Laser
may be attached to equipment that is hot.
Always wear the appropriate PPE to minimize the risk of burns.
Where there is a risk associated with the release of potentially
harmful gases into the operating environment, always use suitable
monitoring equipment.
The gases included in the process being monitored may be toxic,
asphyxiant or flammable.
Before you use the 07931-Series Laser, make sure that all
connections are leak-free at full operating pressure to prevent
exposure of personnel and the environment to the hazardous
gases.
The
analyser
may fail if it is used with sample streams that contain
substances not compatible with those listed in Section 2.8.

07931001A revision 1 © ServomexGroup Limited. 2015 9
Make sure that you install the instrument to conform to all relevant
safety requirements, National Electrical Code and any local
regulations. The installation must be safe for any extremes of
operating conditions which may occur in the operating environment
of the 07931-Series Laser.
Do not install the
analyser
on a surface which is subject to high
levels of vibration or sudden jolts. Sample measurements may not
be accurate and the analyser may be damaged.
1.2 Laser safety
CLASS 3R LASER PRODUCT.
LASER RADIATION. The 07931-Series Laser is a Class 3R laser product.
The laser light is not visible. Do not look into the laser beam. Avoid direct
eye contact with the laser radiation.
The transmitter and receiver units both have a Laser On indicator. This is
ON when the transmitter emits laser radiation from the optical window.
CLASS 3R LASER PRODUCT.
LASER RADIATION. Changes to settings or performance of procedures
other than those specified in this manual may result in hazardous
radiation exposure.
1.3 Certification
1.3.1 Hazardous area installations
Do not modify the unit, either mechanically
or electrically, or the
certification of the instrument will be invalidated and it may not operate
safely.
Exposure to some chemicals may degrade the sealing properties of
materials used in the following devices (North America only):
K1: Relay from Analyser Main Board Sealed Device
K1: Relay from Option Board Sealed Device
K2: Relay from Option Board Sealed Device
Substitution of the following components may impair suitability for
Division 2 (North America only):
K1: Relay from Analyser Main Board Sealed Device
K1: Relay from Option Board Sealed Device
K2: Relay from Option Board Sealed Device

EXPLOSION HAZARD
-
Substitution of components may impair
suitability for CL I, Div 2. (North America only).
Make sure that the
operating environment is within the limits specified in
the product data (section 2.6.5).
Do not install the
07931
-
Series Laser
in a high
-
velocity dust
-
laden
atmosphere.
Do not open the enclosure if an explosive atmosphere is present.
Do not open the enclosure if the 07931-Series Laser is energized.
It is a condition of certification that the unit must be installed following
the appropriate national or international legislation or codes of practice.
In particular, you must make sure that the correct glands are fitted to
cable entries and that you do not compromise the weatherproofing of the
enclosure.
All of the
analyser
electrical connections are considered to be incendive
and therefore must only be connected to safe area equipment.
The equipment is
incapable of passing the dielectric strength test
prescribed by the standards, and so this must be taken into account
during installation.
1.3.2 Hazardous area variants
Do not use hazardous area va
riants with a process atmosphere that
requires EPL Ga. (e.g. Zone 0). If they are used within this process
atmosphere, the hazardous area certification may be invalidated.
Do not use hazardous area variants for oxygen enriched
flammable
samples; that is gases over 21% O2. If they are used with gases
containing over 21% O2the hazardous area certification may be
invalidated.
Hazardous area variants are certified for use with a flammable process
atmosphere at a pressure of 0.8 to 1.1 bar absolute (11.6 to 15.95 psi). If
used with a flammable process atmosphere beyond these limits, the
hazardous area certification may be invalidated.

1.4 Markings
The 07931-Series Laser includes these external markings. Their locations are shown in
section 1.4.1.

2 Introduction
2.1 Product description
The 07931-Series Laser is an advanced gas analyser. It comprises a transmitter unit
(TU) and a receiver unit (RU), with an optional AC to DC power supply, ancillary
equipment and sample cell.
The laser radiation detected by the photo-detector is amplified and transferred to the
transmitter unit through a multi-core cable which connects the receiver and transmitter
electronics. The same cable transfers the required power from the TU to the RU.
Pluggable connectors at each end of the cable, and a removable gland plate, allow you
to easily remove the TU and RU for calibration or maintenance.
For continuous in-situ applications, the 07931-Series Laser is installed directly across
stacks, ducts and reactors typically employing path lengths of 0.1 to 40 m (3.94" - 131
ft.).
