3 Safety Instructions
3.1 Intended Use of the Product
!
Before installation, commissioning and operation select the appropriate digital DTW temperature
transmitter in terms of function and equipment.
Warning
The device 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 device outside of its technical specifications requires the device to be taken out of service immediately
and an inspection by the manufacturer.
When the device is transported from a cold into a warm environment, the formation of condensation may cause the

!
Warning
3.2 Personnel Qualification
For installation and start-up of the DTW the personnel has to be familiar with the relevant regulations and directives of
the country and must have the required qualification. They must have knowledge of measurement and control
technology, have to be acquainted with electric circuits, are capable of carrying out the work described and can
independently recognise potential hazards.
The personnel needs to have the proper training for their work environment and has to comply with the current
regulations for safety at work as prescribed by law!
Working with devices for areas exposed to explosion hazards requires specialist knowledge!
The personnel needs to have knowledge about types of ignition protection, regulations and directives for equipment in
areas exposed to explosion hazards. Depending on operating conditions they need to have the corresponding
knowledge, e. g. of corrosive media.
Risk of injury if qualification is insufficient
Improper handling can result in considerable injuries 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.
iMore safety instructions can be found in the individual chapters.
Allowed storage conditions:
- Storage temperature: -40...+85 °C

3.3 Special Hazards
In addition to all standard regulations, the appropriate existing codes or regulations must also be
followed.
If you do not comply with the appropriate regulations, serious injuries and/or damage can occur!
A protection from electrostatic discharge (ESD) is required.
The proper use of grounded work surfaces and personal wrist straps is required when working with
exposed circuitry (PCB, printed circuit boards), in order to prevent static discharge from damaging
sensitive electronic components.
Do not use this instrument in safety or emergency stop devices. Incorrect use of the device can result in
injury.
There is a 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 voltage
output) can result in life-threatening voltages at the device.

3.4 Responsibility of the Operating Body
There is danger to life caused by areas exposed to explosion hazards. Situations leading to death or
heavy injuries are possible.
The instrument is used in the industrial sector. The operatoring body is therefore responsible for legal obligations
regarding safety at work.
The safety instructions within these operating instructions, as well as the safety, accident prevention and
environmental protection regulations for the application area must be maintained.
The operatoring body is obliged to maintain the product label in a legible condition.
The responsibility for classification of zones lies with the operatoring body and not the manufacturer/supplier of the
equipment.

- Check if the DTW transmitter was delivered in complete assembly.
- Inspect the DTW for possible damage during transportation. Should there be any obvious
damage, inform the transport company and supplier immediately.
- Keep the packaging, as it offers optimal protection during transportation.
- Make sure to protect the connecting contacts from damage.
The digital temperature transmitter DTW is a universal measuring transmitter for resistance thermometers and
potentiometers. It is configurable via PC. The device transforms resistance values or relations (potentiometer)
into a proportional current signal. At the same time the sensors are constantly tested to ensure faultless operation.
The temperature transmitter complies with the requirements of:
- Explosion protection (varies with version)
- Electromagnetic compatibility according to NAMUR-recommendation NE21
- Signaling at analog output according to NAMUR-recommendation NE43
- Sensor break signaling according to NAMUR-recommendation NE89 (Corrosion monitoring of sensor
connection)
