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.
Further important safety instructions can be found in the
individual chapters of these operating instructions.
2.1 Intended use
The model DIH10-Ex connection head with integrated digital display
module (digital indicator) is an all-purpose, configurable loop-powered
indicator for single resistance thermometers (RTD), thermocouples
(TC) and resistance and sensor transmitters.
It is especially applicable where a standard signal of 4 ... 20 mA is
already available.The current-loop display is built into an appropriate
connection head or wall-mounted case, and can thus be used as a
local display in all sectors of industry.The cases are not constituent
elements of the EC-type examination certificate.
The instrument has been designed and built solely for the intended
use described here, and may only be used accordingly.
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.
If the instrument is transported from a cold into a warm environment,
the formation of condensation may result in instrument malfunction.
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 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.
2.3 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!
The programming set for the factory programming must
only be used by the manufacturer, as it does not have
ATEX approval!
The programming of the display must only be made via the
three buttons at the rear of the display!
CAUTION!
■
The operation of these versions in Ex areas is only
permitted in intrinsically safe circuits.
■
In addition to this instruction manual, note the
accompanying EC-type examination certicate
(ZELM 05 ATEX 0260).
■
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.
WARNING!
When cases are used, they must either have their
own suitable approval or comply with the minimum
requirements. IP protection of at least IP 20 applies for all
cases.
However, light metal cases must be qualied in
accordance with EN/IEC 60079-0 section 8.1. In addition,
non-metallic cases or powder-coated cases must meet
the requirements of EN/IEC 60079-0 or have a suitable
warning note.

The current loop indicator can be built into either a
model BSZ-H connection head or BSS-H connection
head (with or without wall-mounting adapter). In this case,
the case requirements referred to are fullled. The cases
are not constituent elements of the EC-type examination
certicate.
2.4 Special hazards
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.
For additional important safety instructions for instruments
with ATEX approval see chapter 2.3 “Additional safety
instructions for instruments per ATEX”.
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 regulations
must also be followed.
WARNING!
Protection from electrostatic discharge (ESD) required!
The proper use of grounded work surfaces and personal
wrist straps is required when working with exposed circuitry
(printed circuit boards), in order to prevent static discharge
from damaging sensitive electronic components.
2. Safety

GB
10 WIKA operating instructions model DIH10-Ex
3330872.01 02/2014 GB/D
To ensure safe working on the instrument, the operating
company must ensure
■
that suitable rst-aid equipment is available and aid is
provided whenever required.
■
that the operating personnel are regularly instructed
in all topics regarding work safety, rst aid and
environmental protection and know the operating
instructions and in particular, the safety instructions
contained therein.
DANGER!
Danger of death caused by electric current
Upon contact with live parts, there is a direct danger of
death.
■
Electrical instruments may only be installed and
connected by skilled electrical 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 dismounted instruments 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.

4.1 Description
The model DIH10-Ex is a universal, microprocessor-controlled display,
monitoring and control instrument. It has an input, to which 4 … 20 mA
standard signals can be connected.
With its simple mounting and open programmability via the easily
accessible buttons, pressure transmitters which are already operating
can also be retrotted quickly.
The display is loop-powered, and so no additional power supply is
needed.The 8 mm high LED display ensures good readability, even in
poor lighting conditions.

5. Transport, packaging and storage
5.1 Transport
Check the instrument for any damage that may have been caused by
transport. Obvious damage must be reported immediately.
5.2 Packaging
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).
5.3 Storage
Permissible conditions at the place of storage:
■
Storage temperature: -20 ... +80 °C
■
Humidity: 35 ... 85 % 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
Store the instrument in its original packaging in a location that fulls
the conditions listed above. If the original packaging is not available,
pack and store the instrument as described below:
1. Wrap the instrument in an antistatic plastic lm.
2. Place the instrument along with shock-absorbent material in the
packaging.
3. If stored for a prolonged period of time (more than 30 days), place a
bag containing a desiccant inside the packaging.
WARNING!
Before storing the instrument (following operation), remove
any residual media.This is of particular importance if
the medium is hazardous to health, e.g. caustic, toxic,
carcinogenic, radioactive, etc.

WARNING!
■
Never connect directly to a voltage supply (e.g. 24 V) as
this will damage the display.

WARNING!
The display is only ever operated in a 4 ... 20 mA current
loop. A direct connection to a voltage supply (e.g. DC 24 V)
will lead to the display being damaged and will invalidate
the warranty.
For a functional check, the display must be powered from a
mA source (e.g. mA transmitter or calibrator).
In normal operation, the display is connected in series with
a 4 ... 20 mA transmitter or connected to the 4 ... 20 mA
analogue output of an instrument.
