2150EX Area Velocity Flow System
Safety Information
General Warnings Before installing, operating, or maintaining this equipment, you
should read this entire manual. While specific hazards may vary
according to location and application, it is still helpful to read
this safety section (which is specific to the 2150EX) and the
general safety information contained in Appendix E. If you have
any questions regarding the equipment or its installation,
contact Teledyne Isco or one of its representatives for assistance.
This manual has been created in compliance with general
requirements for equipment installed in potentially explosive
atmospheres (refer to Clause 28 of EN 50014:1997).
WARNING
Avoid hazardous practices! If you use this instrument in
any way not specified in this manual, the protection
provided by the instrument may be impaired; this will
increase your risk of injury.
WARNING
Intrinsic safety is dependent on proper installation in
accordance with IEC 60079-14 and IEC 60079-17
International Standards, or ATEX Group II, Category 1G
requirements of the authority that has jurisdiction for the
installation of equipment in hazardous areas at your
specific installation site. Installation should be performed
only by trained and qualified personnel.
Hazard Severity Levels This manual applies Hazard Severity Levels to the safety alerts,
These three levels are described in the sample alerts below.
CAUTION
Cautions identify a potential hazard, which if not avoided, may
result in minor or moderate injury. This category can also warn
you of unsafe practices, or conditions that may cause property
damage.
WARNING
Warnings identify a potentially hazardous condition, which
if not avoided, could result in death or serious injury.
DANGER
DANGER – limited to the most extreme situations
to identify an imminent hazard, which if not
avoided, will result in death or serious injury.

Hazard Symbols The equipment and this manual use symbols to warn of hazards.
The symbols are explained below.
2150EX Safety
Information
The intrinsically safe 2150EX is intended for use in potentially
explosive atmospheres, and complies with ATEX Directive
94/9/EC. The 2150EX is Group II, Category 1G equipment for use
in gas hazard zones 0, 1, and 2.
The equipment is not designed with dust ignition protection for
dust hazard zones 20, 21, or 22.
Hazard Symbols
Warnings and Cautions
The exclamation point within the triangle is a warning sign alerting you of
important instructions in the instrument’s manual.
The lightning flash and arrowhead within the triangle is a warning sign alert-
ing you of “dangerous voltage” inside the product.

2150EX Module Connected to
2191EX Battery Module and AV2150EX Sensor
Installation should be completed with adherence to local require-
ments for ATEX Group II, Category 1G or 2G equipment as
appropriate, and should be done by trained and qualified per-
sonnel.
Designed for safety The purpose of intrinsic safety is to limit the energy available to
a given circuit or device to a level where electrical discharge
(sparking) cannot ignite the hazardous (flammable or explosive)
atmosphere. With no spark ignition possible, safe operation of
the equipment in areas with hazardous atmospheres is possible.
The durable 2150EX, 2191EX, 2196EX, and 2194EX enclosures
are made with ABS plastic embedded with conductive carbon
fiber, giving the units low surface resistance to minimize electro-
static energy.
The lithium thionyl chloride batteries and the lead acid batteries
used in the 2191EX Battery Module operate at a low voltage and
are contained in sealed battery packs.
The 2150EX system has been designed so that it does not cause
physical injury or other harm due to contact. It does not produce
excessive surface temperature or dangerous radiation. When
used properly, it does not present any non-electrical dangers.

Labels Read all labels carefully before installing the equipment!
The 2150EX and its components are clearly labeled with color
and/or text so you know what can be located in a safe or haz-
ardous area (see figure below). For example, on the label shown
below, light blue is used to indicate the intrinsically safe end and
yellow to indicate the non-protected end of the cable and con-
nector.
Example of Safe and Hazardous Area Labeling on RS232EX Cable
Some system components have an X marking, as shown in the
example below. The X marking indicates that there are special
conditions that must be met to ensure intrinsic safety. In the case
of the sensor cable, there is a danger of static electricity. The
cable is labeled with a warning telling you that you should not
rub the sensor with a dry cloth, as this might generate static
electricity.

Where applicable, the labels contain other information, such as
voltage, serial number identification, etc. For example, the label
shown below indicates the maximum input voltage (Ui), input
current (Ii), and input power (Pi) that can be applied to the
2150EX network port without invalidating intrinsic safety. It
also shows the internal capacitance (Ci), and internal inductance
(Li) that must be allowed by any power source.
Example of 2150EX Label
When you compare the 2150EX label in the figure above with the
2191EX label in the figure below, you can see they provide a
helpful reference so you can make sure your connections are safe.
Example of 2191EX Label
For example, the 2150EX network port cannot have an input
voltage greater than 9.282V. When you look at the label on the
power source (in this case the 2191EX), you can see that the
maximum output voltage is 9.282V. From this you know that you
can safely connect the two, and won’t be providing too much
voltage to the 2150EX unit.
Note
This information is not intended to fully explain entity parame-
ters. Other publications should be referenced for more detailed
explanations.

Installation Installation of the 2150EX system is described in this manual.
Typical round-pipe installations are shown in Figures 2-1 and
2-2, and Appendix E provides information on general safety pro-
cedures for work in manholes and sewers.
When the equipment is installed in accordance with the instruc-
tions in this manual, it will not be subjected to dangerous
mechanical or thermal stresses. It should not be installed where
it may be attacked by existing or foreseeable aggressive sub-
stances that could damage the module enclosures. The enclo-
sures are made of Acrylonitrile Butadiene Stytene (ABS) plastic.
Substances that may cause damage include organic solvents
(ketones and esters, aromatic and chlorinated hydrocarbons),
alcohols, hydrocarbons, fuels, and UV radiation.
Repair and Maintenance Refer to Section 4 of this manual for instructions regarding
periodic maintenance of the 2150EX and its components.

The internal components of the 2150EX System are not user-ser-
viceable. The case is completely sealed to protect the internal
components. If you think your module requires repair, contact
Teledyne Isco’s Technical Service Department.
Rapidly failing desiccant may indicate a crack.
WARNING
Any cracks in the module case will impair the safety
protection. If this occurs, return the unit to Teledyne Isco
for a replacement.
Components of the AV2150EX Sensor are encapsulated in plastic
resin and are not user-serviceable. If any part of the AV Sensor
fails, it must be replaced.
