1 General information

1 General information

 The instrument described in the operating instructions has been

designed and manufactured using state-of-the-art technology.
All components are subject to stringent quality and environmental
criteria during production. Our management systems are certified to
ISO 9001.

 These operating instructions contain important information on handling

the instrument. Working safely requires that all safety instructions and
work instructions are observed.

 Observe the relevant local accident prevention regulations and general

safety regulations for the instrument's range of use.

 The operating instructions are part of the instrument and must be kept

in the immediate vicinity of the instrument and readily accessible to
skilled personnel at any time.

 Skilled personnel must have carefully read and understood the

operating instructions, prior to beginning any work.

 The manufacturer's liability is void in the case of any damage caused by

using the product contrary to its intended use, non-compliance with
these operating instructions, assignment of insufficiently qualified skilled
personnel or unauthorised modifications to the instrument.

 The general terms and conditions, contained in the sales

2 Safety

WARNING!

Explanation of symbols

WARNING!

... indicates a potentially dangerous situation that can result
in serious injury or death, if not avoided.

Information

... points out useful tips, recommendations and information
for efficient and trouble-free operation.

DANGER!

...identifies hazards caused by electric power. Should the
safety instructions not be observed, there is a risk of serious
or fatal injury.

2 Safety

Before installation, commissioning and operation, ensure that
the appropriate instrument has been selected in terms of
measuring range, design and specific measuring conditions.
Non-observance can result in serious injury and/or damage
to equipment.

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

2.1 Intended use

The digital indicator DI35-M is used for measurement and indication of sensor
signals, thermocouples and RTDs. Signals can be put out via an analogue
output for further processing.

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

WIKA operating instructions digital indicator model DI35-M 5

2 Safety

Please read the following safety advice and the assembly before installation
and keep it for future reference.

If the instrument is transported 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.

Notes on installation

 There must be no magnetic or electric fields in the vicinity of the device,

e.g. due to transformers, mobile phones or electrostatic discharge.

 Do not install inductive consumers (relays, solenoid valves etc.) near

the device and suppress any interference with the aid of RC spark
extinguishing combinations or free-wheeling diodes.

 Keep input, output and supply lines separate from one another and do

not lay them parallel with each other. Position “go” and “return lines”
next to one another. Where possible use twisted pair. So, you receive
best measuring results.

 Screen off and twist sensor lines. Do not lay current-carrying lines in the

vicinity. Connect the screening on one side on a suitable potential
equaliser (normally signal ground).

 Do not install several devices immediately above one another or in an

extremely thermal isolated housing. Due to the internal heat dissipation
of the devices, the recommended ambient temperature can be
excessed.

 The device is not suitable for installation in areas where there is a risk

of explosion.

 Any electrical connection deviating from the connection diagram can

endanger human life and/or can destroy the equipment.

 The terminal area of the devices is part of the service. Here electrostatic

discharge needs to be avoided. Attention! High voltages can cause
dangerous body currents.

 Galvanic insulated potentials within one complex need to be placed on

a appropriate point (normally earth or machines ground). So, a lower
disturbance sensibility against impacted energy can be reached and
dangerous potentials, that can occur on long lines or due to faulty
wiring, can be avoided.

 The fuse rating of the supply voltage should not exceed a value of 6A

N.B. fuse.

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

 Keep unqualified personnel away from hazardous areas.

DANGER!

WARNING!

death or serious injury and material damage.

2.2 Personnel qualification

Risk of injury should qualification be insufficient!

Improper handling can result in considerable injury and
damage to equipment.

Skilled electrical personnel

Skilled electrical 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 work on
electrical systems and independently recognising and avoiding potential
hazards.
The skilled electrical personnel have been specifically trained for the work
environment they are working in and know the relevant standards and
regulations.
The skilled electrical personnel must comply with current legal accident
prevention regulations.

 The activities described in these operating instructions

may only be carried out by skilled personnel who have
the qualifications described below.

2.3 Special hazards

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 mounted

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!

Do NOT use this product as safety or emergency stopping
device, or in any other application where failure of the
product could result in personal injury or material damage.
Failure to comply with these instructions could result in

4 Design and function

4.1 Short description

The digital indicator DI35-M is a multi-function and highly accurate digital
indicator. It has a multi-function input with 29 different calibrated input
configurations, which can be selected via the terminal configuration and by
the selection of the input signal in the instrument configuration. Furthermore
the possibility of sensor calibration and linearisation with up to 30 points is
offered.
The standard features are completed by the adjustable sampling rate and
display time as well as the input offset for the correction of zero offsets or
sensor drifts and TARA and HOLD function. The measured value or one of
the functions can be indicated and used as output signal.

As an option up to 4 fully programmable alarm outputs, an analogue output
signal, a serial interface and a transmitter power supply are available.

4.2 Scope of delivery

The scope of delivery is:

 Indicator
 2 fixing elements
 Seal
 Operating instructions

Cross-check scope of delivery with delivery note.

5 Transport, packaging and storage

5.1 Transport

Check 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).

WARNING!

5.3 Storage

Permissible conditions at the place of storage:

 Storage temperature: -20 ... +80 °C
 Humidity: 0 ... 75 % 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
 Potentially explosive environments, flammable atmospheres

Store the instrument in its original packaging in a location that fulfils 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 film.

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.

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.

6 Commissoning, operation
