Safety notes
1 Safety notes
Safe and secure operation of the head transmitter can only be guaranteed if the
operating instructions and all safety notes contained are read, understood and
followed.
1.1 Correct use
• The unit is a universal, presettable temperature transmitter for resistance
thermometer (RTD), thermocouple (TC) as well as resistance and voltage sensors.
The unit is constructed for mounting in a connection head (form B) and a field
housing.
• The user cannot be held responsible for damage caused by misuse of the unit.
• Separate Ex documentation, is contained in this operating manual, for
measurement systems that are to mounted in hazardous areas. The installation
conditions as well as the connection values indicated in these instructions must
be completely followed!
1.2 Installation, commissioning and operation
The unit is constructed using the most up-to-date production equipment and
complies to the safety requirements of the EU guidelines. However. If it is installed
incorrectly or is misused then certain application dangers can occur. Installation,
wiring and maintenance of the unit must only be done by trained skilled personnel
who are authorised to do so by the plant operator. These skilled staff must have read
and understood these instructions and must also follow them to the letter. The plant
operator must make sure that the measurement system has been correctly wired to
the connection schematics.

Function and system construction
3 Function and system construction
3.1 Function
Electronic monitoring and transformation of various input signals into an analogue
output signal in industrial temperature measurement. The head transmitter is mounted
in a connection head form B or separated from the sensor in field housing. Setting up
of the head transmitter is done using a PC and setting up software. The configuration
kit is required for setting up the head transmitter.
3.2 Measurement system
Transforming the following input signals:
• Resistance thermometers (RTD) and resistance sensors
(in 2-,3- or 4-wire connection systems)
• Thermocouples (TC) and
• voltage sensors into a scalable analogue output signal (4...20 mA or 20...4 mA).
Fault monitoring of:
• Measurement range override or undercut
• Sensor breakage and short circuit
[1]
Installation
conditions
The head transmitter is set up using a PC and the PC setting up programme together
with the configuration kit. The kit can be obtained as a unit accessory.
Application in hazardous areas is certified to ATEX II 1 G
EEx ia IIC T4/T5/T6.
4 Installation
4.1 Installation conditions
• When installing and operating the unit please take note of the allowable ambient
temperature (see chapter 11: Technical data).
• When operating in hazardous areas please take note and operate within the limits
set in the certification (see chapter 11: Technical data).
Dimensions
The head transmitter dimensions can be found in Chapter 11: Technical data.
Installation point
• Sensor connection head to DIN 43 729 Form B
• Field housing
Installation angle
There are no limits as to the angle on installation.
Installation
4.2 Installation
For installation proceed as follows:
Installing in a sensor connection head to DIN 43 729 Form B (Fig. 4.1)
• Feed the sensor inset cables (Pos. 5) through the central hole in the head
transmitter (Pos. 4).
• Place the installation springs (Pos. 3) onto the screws (Pos. 2).
• Feed the installation screws (Pos. 2) through the holes in the head transmitter and
the holes in the sensor inset (Pos. 5). Fix both screws using the circlips (Pos. 6).
• Position the head transmitter in the connection head in such a way so that the
current output terminals (terminal 1 and 2) are towards the cable entry gland
(Pos. 7).
• Fix the head transmitter (Pos. 4) and sensor inset (Pos. 5) into the connection head.
