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 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 manufacturer
cannot be held responsible for damage caused by misuse of the unit.

1.2 Installation, commissioning and operation

The unit is constructed using the most up-to-date production equipment and complies with the safety requirements of the EU guidelines.
If it is installed incorrectly or misused certain application dangers can occur. Trained personnel must do installation, wiring and
maintenance of the unit. These personnel must have read and understood these instructions and must follow them to the letter.

2 FUNCTION AND SYSTEM CONSTRUCTION

2.1 Function

Provides electronic monitoring and transformation of various input signals into an analog output signal in industrial temperature
measurement. The head transmitter is mounted in a connection head form B or separated from the sensor in a field housing.
Setting up of the head transmitter is done using PC and configuration software. The configuration kit is required for setting up the
head transmitter.

2.2 Measurement system

Transforming the following input signals:

• Resistance thermometers (RTD) and resistance sensors (in 2, 3 or 4 wire connection systems)

• Thermocouples (TC)

• Voltage sensors into a scalable analog output signal (4...20 or 20...4) mA

Fault monitoring of:

• Measurement range override or undercut

• Sensor breakage and short circuit - not for thermocouples (TC)

3 INSTALLATION

3.1 Installation conditions

Ambient temperature: (-40 to 85) °C [-40 to 185] °F
Installation area: Field housing; connection head Form B according to DIN 43 729

Installation angle: No limit

Safety notes: The unit must only be powered by a power supply that operates using an IEC 61010-1 compliant energy limited

circuit.

3.2 Installation

• Feed the sensor leadwires through the central hole in the head transmitter

• Position the head transmitter in the connection head in such way so that the current output terminals (terminals 1 and 2) are

towards the cable entry gland.

• Feed the installation screws through the holes in the head transmitter.

• Screw the head transmitter into the field housing using a screwdriver while not over tightening.

4.2 Measurement unit connection
Attention: Switch off power supply before opening the housing cover. Do not install or connect the unit to power. If this is not followed

parts of the electronic circuit will be damaged.

• Sensors: Connect the sensor lead to the respective head transmitter terminals (Terminals 3 to 6) by following the wiring diagram
(see figure 4.1).

• Output signal and power supply: Open the PG cable gland on the head transmitter or field housing. Feed the cable through the
opening in the PG cable gland and then connect the cable cores to terminals 1 and 2 according to the wiring diagram (see figure

4.1).

• PC configuration (SETUP socket): Open the flap on the SETUP socket (Figure 4.1, Pos. A) and connect the SETUP connection

cable.

Note: The screws on the terminals must be screwed tightly. Head transmitter configuration during measurement operation is possible.
There is no need to disconnect leads.

POTENTIAL LEVELING

Please take note when installing the head transmitter remotely in a field housing. The screen on the (4 to 20) mA signal output must
have the same potential as the screen at the sensor connections. When using earthed thermocouples, screening of the output
(4 to 20) mA cable is recommended. In plants with strong electromagnetic fields, screening of all cables with a low ohm connection

to the transmitter housing is recommended.
