Function and system construction3 Function and system construction3.1 FunctionFunctionElectronic monitoring and transformation of various input signals into an analogueoutput signal in industrial temperature measurement. The head transmitter is mountedin a connection head form B or separated from the sensor in field housing. Setting upof the head transmitter is done using a PC and setting up software. The configurationkit is required for setting up the head transmitter.3.2 Measurement systemMeasurementsystemTransforming 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]The head transmitter is set up using a PC and the PC setting up programme togetherwith the configuration kit. The kit can be obtained as a unit accessory.Application in hazardous areas is certified to ATEX II 1 GEEx ia IIC T4/T5/T6.4 Installation4.1 Installation conditionsInstallationconditions When installing and operating the unit please take note of the allowable ambienttemperature (see chapter 11: Technical data). When operating in hazardous areas please take note and operate within the limitsset in the certification (see chapter 11: Technical data).DimensionsThe head transmitter dimensions can be found in Chapter 11: Technical data.Installation point Sensor connection head to DIN 43 729 Form B Field housingInstallation angleThere are no limits as to the angle on installation.4.2 InstallationInstallationFor 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 headtransmitter (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 andthe 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 thecurrent 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.[1] not for thermocouples (TC)23

InstallationInstallation in a field housing (Fig. 4.2) Feed the installation screws (Pos. 2) with installation springs (Pos. 3) through theholes in the head transmitter (Pos. 4). Fix these using the circlips (Pos. 5). Screw the head transmitter into the field housing using a screw driver.Attention:In order to avoid damaging the head transmitter do not over tighten the installationscrews.Pos.1: CoverPos.2:Installation screwsPos.3:Installation springsPos.4:Head transmitterPos.5:Sensor inset withconnection cablesPos.6:CirclipsPos:7:Cable glandFig. 4.1: Installation of head transmitter into aForm B sensor connection head.24Pos.1: CoverPos.2: Installation screwsPos.3: Installation springsPos.4: Head transmitterPos.5: CirclipsPos:6: Field housingFig. 4.2: Installation of head transmitter into afield housing

Wiring5 Wiring5.1 OverviewWiring overviewTerminal layoutPos.A: SETUP socket2-wire3-wire4-wireFig. 5.1: Head transmitter wiringMeasurement unitconnection5.2 Measurement unit connectionAttention:Switch off power supply before opening the housing cover. Do not install or connectthe unit to mains power. If this is not followed parts of the electronic circuit will bedamaged. Sensors:Connect the sensor cables to the respective head transmitter terminals(Terminals 3 to 6) by following the wiring diagram (see fig. 5.1). Output signal and power supply:Open the PG cable gland on the head transmitter or field housing. Feed the cablethrough the opening in the PG cable gland and then connect the cable cores toterminals 1 and 2 according to the wiring diagram (see fig. 5.1). PC configuration (SETUP socket):Open the flap on the SETUP socket (Fig. 5.1, Pos. A) and connect the SETUPconnection cable.Hint:The screws on the terminals must be screwed up tightly. Head transmitterconfiguration during measurement operation is possible. There is no need todisconnect cables!Potential levelingHint:Please take note of the following when installing the head transmitter remotely in afield housing. The screen on the output (output signal 4.20 mA) must have the samepotential as the screen at the sensor connections!For an effective screening the cable screen must be widely connected to the fieldhousing. This can be achieved by connecting the cable screen to the specialEMC-PG13.5 cable gland.Open the field housing PG cable gland and connnect the screen of the output andsensor connection according to Fig. 5.2.25

WiringWhen using earthed thermocouples screening of theoutput cable (4 . 20 mA cable) is recommended.In plants with strong EMC problems screening of allcables with a low ohm connection to the transmitterhousing is aabbbbbbbbFig. 5.2: Screening onremote installation26
