Pyromation Series 441 - Manual

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.
