14008548.05 12/2016 EN/DE

DANGER!

... identifies hazards caused by electric power. Should the safety instructions not

be observed, there is a risk of serious or fatal injury.

WARNING!

... indicates a potentially dangerous situation in the hazardous area that can

result in serious injury or death, if not avoided.

2. Safety

WARNING!

Before mounting, commissioning and operation, make sure that the display is

suitable for the application.

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

WARNING!

This is protection class 3 equipment for connection at low voltages, which

are separated from the power supply or voltage by greater than AC 50 V or

DC 120 V. Preferably, a connection to an SELV or PELV circuit is recommended;

alternatively protective measures from HD 60346-4-41 (DIN VDE 0100-410).

Alternatively for North America:

The connection can be made in line with “Class 2 Circuits” or “Class 2 Power

Units” in accordance with CEC (Canadian Electrical Code) or NEC (National

Electrical Code).

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

these operating instructions.

2.1 Intended use

The field indicators models DIH50, DIH52 are used for converting an analogue current

signal (4 … 20 mA) into an indication of the corresponding measured value and are

intended for mounting in the field.

They comprise a display and operating unit without power supply for looping in 4 … 20 mA/

HART®circuits.

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

and may only be used accordingly.

The technical specifications contained in these operating instructions must be observed.

Improper handling or operation of the instrument outside of its technical specifications

requires the instrument to be taken out of service immediately and inspected by an

authorised WIKA service engineer.

14008548.05 12/2016 EN/DE

If the instrument is moved from a cold into a warm environment, the formation of

condensation may result in the instrument malfunctioning. Before putting it back into

operation, wait for the instrument temperature and the room temperature to equalise.

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

the intended use.

2.2 Personnel qualification

WARNING!

Risk of injury if qualification is insufficient!

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 qualifications described below.

■

Keep unqualified 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-specific 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.

2.3 Additional safety instructions for instruments per ATEX

WARNING!

Non-observance of these instructions and their contents may result in the loss

of explosion protection.

WARNING!

Do not use field indicators with any damage to the exterior!

CAUTION!

■

Repairs are strictly prohibited.

■

Do not use displays presenting externally visible damage.

■

Observe the instructions for mounting and operation as well as the

requirements for the use of the devices in hazardous areas.

2. Safety

14008548.05 12/2016 EN/DE

2.4 Special hazards

WARNING!

Observe the information given in the applicable type examination certificate and

the relevant country-specific regulations for installation and use in hazardous

areas (e.g. IEC/EN 60079-14, NEC, CEC). Non-observance can result in serious

injury and/or damage to the equipment.

For further important safety instructions for instruments with ATEX approval, see

chapter 9 “Information on mounting and operation in hazardous areas”.

WARNING!

For hazardous media such as oxygen, acetylene, flammable or toxic gases or

liquids, and refrigeration plants, compressors, etc., in addition to all standard

regulations, the appropriate existing codes or regulations must also be followed.

WARNING!

To ensure safe working on the instrument, the operating company must ensure

■

that suitable first-aid equipment is available and aid is provided whenever

required,

■

that the operating personnel are regularly instructed in all topics regarding

work safety, first aid and environmental protection, and know the operating

instructions, in particular the section on safety instructions.

WARNING!

When working during a running process operation, measures to prevent

electrostatic discharge from the connecting terminals should be taken, as a

discharge could lead to temporary corruption of the measured value.

DANGER!

Danger of death caused by electric current

Upon contact with live parts, there is a direct danger of death.

■

The instrument may only be installed and mounted by skilled personnel.

■

Operation using a defective power supply unit (e.g. short circuit from the

mains voltage to the output voltage) can result in life-threatening voltages at

the instrument!

WARNING!

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

environment and equipment.Take sufficient precautionary measures.

4. Design and function

4.1 Description

The field indicators are external display and operating units without separate power supply

for 4 … 20 mA/HART®sensors. The instruments are used for measured value display and

operation remote from the measuring point.They are looped anywhere in the 4 … 20 mA

signal line and measure the current in the current loop. At the same time, they read and

display the measured values with unit via the HART®signal.

The field indicators are powered directly from the 4 ... 20 mA current loop, with a resultant

voltage drop of less than 3 V.

The field indicators meet the requirements of:

■

Explosion protection (depending on the version)

■

Electromagnetic compatibility in accordance with DIN EN 61326 and NAMUR

recommendation NE21
