Series 440 Installation and Operating Instructions

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). The unit is constructed for mounting in
a connection head 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 is 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 of input signals into an analog output signal in industrial temperature measurement. The head
transmitter is mounted in a connection head 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) (in 2 or 3 wire connection systems)

Fault monitoring of:

• Measurement range override or undercut

• Sensor breakage and short circuit

3 INSTALLATION

3.1 Installation conditions

Ambient temperature: (-40 to 85) °C [-40 to 185] °F
Installation area: Field housing; connection head
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

• Feed the installation screws through the slots 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 mains power. If this is

not followed parts of the electronic circuit will be damaged.

• Sensors:

Connect the sensor leads to the respective head transmitter terminals (Terminals 1 to 3) 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 4 and 5 according to the wiring diagram (see figure 4.1).

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

Hint: 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.

5.2 Communication

The head transmitter must be set up using a PC and configuration kit. The following points must be taken into account if trouble
free setting up is to be achieved:

• Configuration software installation.

• Connect the head transmitter to the PC using the connection cable from the configuration kit.
