2. Safety

WARNING!

Before installation, commissioning and operation, ensure that the appropriate instrument has been

selected in terms of measuring range, design and specic measuring conditions.

Non-observance can result in serious injury and/or damage to the equipment.

WARNING!

Danger of injury and damage to property due to escaping media

Escaping media can lead to serious injury. In the event of failure, components can be ejected or media

exhausted under high pressure.

■

Open the connections only after the system has been depressurised.

■

For pressures from 1,000 bar, employ a protective device to prevent parts from being ejected.The

protective device must not be removable without the use of tools.

■

Always operate the pressure measuring instrument within the overload safety, see chapter 3 “Speci-

cations”.

■

Ensure that the pressure in the system as a whole does not exceed the lowest maximum pressure of

any of its components. If varying or dierent pressures are to be expected in the system, components

must be used that can withstand the maximum expected pressure spikes.

■

Installation in self-draining position (there must be no collection of liquid in the connection channel of

the transmitter).

■

Plant conditions which can lead to the formation of atomic hydrogen in the connection channel of the

transmitter must be completely avoided.

■

Observe the operating parameters in accordance with chapter 3 “Specications”.

■

Actions or alterations to the pressure transmitter, which are not described in these operating instruc-

tions, are not permitted.

Further important safety instructions can be found in the individual chapters of these operating instruc-

tions.

2.1 Intended use

The pressure transmitter is an intrinsically-safe supplied pressure measuring instrument and is used for the continuous

monitoring of gaseous media or liquids in potentially explosive areas which require category 1, 1/2 and 2 equipment.

Standards used: IEC 60079-0:2011, IEC 60079-11:2011, IEC 60079-26:2006

The instrument has been designed and built solely for the intended use described here, and may only be used accor-

dingly.

The technical specications contained in these operating instructions must be observed. Improper handling or

operation of the instrument outside of its technical specications requires the instrument to be taken out of service

immediately and inspected by an authorised WIKA service engineer.

2.2 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.

■

Keep unqualied personnel away from hazardous areas.

Skilled personnel

Skilled personnel 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 regulations, current standards and

directives, are capable of carrying out the work described and independently recognising potential hazards.

Special operating conditions require further appropriate knowledge, e.g. of aggressive media.

2. Safety

2.3 Special hazards

WARNING!

For ATEX/IECEx ignition protection types Ex nA and Ex tc: The thermal tests per EN 60079-0:2011

26.5.1 were carried out for operation in the nominal pressure range.

WARNING!

Observe the information given in the applicable type examination certicate and the relevant country-

specic regulations for installation and use in hazardous areas (e.g. IEC 60079-14, NEC, CEC).

Non-observance can result in serious injury and/or damage to the equipment.

WARNING!

Physical injury and damage to property caused by hair-line cracks

The service life of the pressure transmitter is limited by a maximum number of load cycles.The

maximum number depends on the pressure prole of the application (extent of change in pressure, time

of pressure rise and pressure drop, ...). Once the maximum number of load cycles has been exceeded,

it can lead to leaks through hair-line cracks, which can cause physical injury and damage to property.

■

Request the maximum number of load cycles from the manufacturer.

■

Replace the pressure transmitter once it has exceeded the maximum number of load cycles.

■

Take safety measures to eliminate hazards due to hair-line cracks.

WARNING!

For hazardous media such as oxygen, acetylene, ammable or toxic gases or liquids, and refrigeration

plants, compressors, etc., in addition to all standard regulations, the appropriate existing codes or regula-

tions must also be followed.

WARNING!

Residual media in the dismounted instrument can result in a risk to persons, the environment and

equipment. Take sucient precautionary measures.

Do not use this instrument in safety or emergency stop devices. Incorrect use of the instrument can

result in injury.

Should a failure occur, aggressive media with extremely high temperature and under high pressure or

vacuum may be present at the instrument.

Further important safety instructions can be found in the individual chapters of these operating

instructions.
