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
documentation, shall apply.
Subject to technical modifications.

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 DI30 is designed for the evaluation and display measuring transmitter
signals. With the alarm outputs, it is possible to perform simple control tasks.
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 DI30 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).
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 1A
N.B. fuse.
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.

2 Safety
WARNING!
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

4.1 Short description
With the digital indicator DI30 standard signals DC 0/4…20 mA or DC
0…5/10 V can be measured. The 4 digit display shows the measurements or
the scaled value of the measurement. During programming the display is
used to indicate the set values and the user prompts.
Two relays (alarm outputs 1 and 2) are available to monitor threshold values,
the status of which is displayed via two separate LED on the front. The
integrated DC 24 V transmitter supply is used to supply connected sensors.
