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.  Further information:

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.

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.
