Safety Information

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.

2150EX Area Velocity Flow System

Safety Information

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.

Symboles de sécurité

Ce symbole signale l’existence d’instructions importantes relatives au pro-

duit dans ce manuel.

Ce symbole signale la présence d’un danger d’électocution.

Warnungen und Vorsichtshinweise

Das Ausrufezeichen in Dreieck ist ein Warnzeichen, das Sie darauf

aufmerksam macht, daß wichtige Anleitungen zu diesem Handbuch

gehören.

Der gepfeilte Blitz im Dreieck ist ein Warnzeichen, das Sei vor “gefährlichen

Spannungen” im Inneren des Produkts warnt.

Advertencias y Precauciones

Esta señal le advierte sobre la importancia de las instrucciones del manual

que acompañan a este producto.

Esta señal alerta sobre la presencia de alto voltaje en el interior del pro-

ducto.

2150EX Area Velocity Flow System

Safety Information

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.

Safety Information

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.

ELECTROSTATIC HAZARD

DO NOT RUB

2150EX Area Velocity Flow System

Safety Information

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.

2150EX Area Velocity Flow System

Safety Information

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.
