1. General information

2. Design and function

2.1 Description

The switch contacts permanently installed in the pressure gauge close or open

at set limit values, depending on the switching function. Switching functions are:

Normally closed, normally open, change-over contact.

Instruments with switch contact model 821

Model 821 magnetic snap-action contacts are auxiliary current switches which

open or close connected electric circuits via a contact arm which is moved by the

instrument pointer.

Instruments with switch contact model 851

Model 851 reed contacts are auxiliary current switches which open or close con-

nected electric circuits at the set limit values via a permanent magnet which is

moved by the instrument pointer.The reed contacts used are bistable switches,

which keep their condition after a signal change up to the next actuation.

Instruments with switch contact model 830 E

Theinductivecontactwithintegratedmodel830Eswitchingampliercanswitch

small loads directly. This is, for example, the case with applications with program-

mable logic controllers (PLCs).

The advantages of inductive contacts are the particularly fail-safe contact opera-

tion,nowearduetoproximitycontactoperationaswellasvirtuallynoeectonthe

measuring system.

No additional control unit is required.

The electronic contact is a 2- or 3-wire design with PNP output.

3. Safety

3.1 Explanation of symbols

WARNING!

... indicates a potentially dangerous situation that can result in seri-

ous injury or death, if not avoided.

WARNING!

... indicates a potentially dangerous situation that can result in burns,

caused by hot surfaces or liquids, if not avoided.

Information

... points out useful tips, recommendations and information for ef-

cientandtrouble-freeoperation.

3.2 Intended use

Wherever the process pressure has to be indicated locally and, at the same time,

circuitsneedtobeswitched,theswitchGAUGEndsitsuse.

These instruments are used to control process values, to monitor plants and to

switch circuits in industrial applications.

This instrument is not permitted to be used in hazardous areas!

Only use the instrument in applications that lie within its technical performance

limits (e.g. max. ambient temperature, material compatibility, ...).

→Forperformancelimitsseechapter9“Specications”.

The instrument has been designed and built solely for the intended use described

here, and may only be used accordingly.

The manufacturer shall not be liable for claims of any type based on operation

contrary to the intended use.

▶ Do not use the instrument within hazardous areas.

▶ Do not use the instrument with abrasive or viscous media.

Anyusebeyondordierenttotheintendeduseisconsideredasimproperuse.

Do not use this instrument in safety or emergency stop devices.

3.4 Personnel qualication

WARNING!

Risk of injury should qualication be insucient!

Improper handling can result in considerable injury and damage to

equipment.

▶ The activities described in these operating instructions may only

becarriedoutbyskilledpersonnelwhohavethequalications

described below.

3.5 Skilled personnel

Skilled personnel, authorised by the operator, are understood to be personnel

who, based on their technical training, knowledge of measurement and control

technologyandontheirexperienceandknowledgeofcountry-specicregula-

tions, current standards and directives, are capable of carrying out the work

described and independently recognising potential hazards.

3.6 Special hazards

WARNING!

Forhazardousmediasuchasoxygen,acetylene,ammableortoxic

gases or liquids, and refrigeration plants, compressors, etc., in ad-

dition to all standard regulations, the appropriate existing codes or

regulations must also be followed.

WARNING!

Residual media in dismounted measuring instruments can result in a

risk to persons, the environment and equipment.

Takesucientprecautionarymeasures.

4. Transport, packaging and storage

4.1 Transport

Check the instrument for any damage that may have been caused by transport.

Obvious damage must be reported immediately.

CAUTION!

Damage through improper transport

With improper transport, a high level of damage to property can

occur.

▶ When unloading packed goods upon delivery as well as during

internal transport, proceed carefully and observe the symbols on

the packaging.

▶ With internal transport, observe the instructions in chapter 4.2

“Packagingandstorage”.

4.2 Packaging and storage

Do not remove packaging until just before mounting.

Keep the packaging as it will provide optimum protection during transport (e.g.

change in installation site, sending for repair).

4.3 Storage

Permissible conditions at the place of storage

Storage temperature: -20 ... +70 °C

Humidity:≤80%relativehumidity(nocondensation)

Avoid exposure to the following factors:

■

Direct sunlight or proximity to hot objects

■

Mechanical vibration, mechanical shock (putting it down hard)

■

Soot, vapour, dust and corrosive gases

■

Hazardousenvironments,ammableatmospheres

WARNING!

Before storing the instrument, any residual media must be removed.

This is of particular importance if the medium is hazardous to health,

e.g. caustic, toxic, carcinogenic, radioactive, etc.

5. Commissioning, operation

5.1 Mechanical connection

In accordance with the general technical regulations for pressure gauges (e.g.

EN837-2“Selectionandinstallationrecommendationsforpressuregauges”).

When screwing the instruments in, the force required for sealing must not be

appliedthroughthecase,butonlythroughthespanneratsprovidedforthis

purpose, and using a suitable tool.

Forparallelthreads,useatgaskets,lens-typesealingringsorWIKAprole

sealings at the sealing face .With tapered threads (e.g. NPT threads), sealing is

made in the threads , using a suitable sealing material (EN 837-2).

The torque depends on the sealing used. In order to orientate the measuring

instrument so that it can be read as well as possible, a connection with clamp

socketorunionnutshouldbeused.Whenablow-outdeviceisttedtoaninstru-

ment, it must be protected against being blocked by debris and dirt.
