D−FL 100 Seite 205. Start-Up / Error Messages5.1. Start-up of the TransducerThe differential pressure bar is equipped standard with a differential pressure transducer 2010TD madeby ABB without a display.The transducer will be shipped adjusted (* by Durag. After mounting the transmitter it is only necessaryto do a zero point adjustment.1) turn the switching valve to the position zero point adjustment2) open exhaust screws and wait 30 sec.3) open the key-cover on the top of the transducer4) press down the lock-key „ / M“ with a screwdriver and turn it 90°5) press the „0% / -“ key once6) turn back the lock-key to lock the transducerNow the transducer is adjusted ans should be readout 4mA.If you want to change the measuring range there are three possibilities:• 1) open the key-cover on the top of the transducer2) press down the lock-key „ / M“ with a screwdriver and turn it 90°3) connect a definied pressure for the beginning of the measuring range (normaly 0 mbar) andwait 30s for stabilisation4) press the „0% / -“ Key once5) connect pressure for the end of the measuring range and wait 30s for stabilisation6) press the „100% / +“ Key once7) turn back the lock-key to lock the transducer• It is possible to order a LC-display with two additional keys. With this display you can change veryparameter of the transducer.• The transducers have a HART-interface for programming the parametersNote: you have to change the parameter of your evaluation unit (D-FL100-10) also.(* measuring range see chapter 9.1; damping 5s; transfer function: rootGmbH
D−FL 100 Seite 215.2. Start-up of the D-FL 100-10 Display• After all electrical connections have been made, parameters to calculate volume or mass flow canbe set in the D-FL 100-10 Display. This is done by setting the turning knob.Drehschalterturning knobFig. 19:Turning knobThe turning knob has the following settings:Turning knob settingOperating mode0 measuring mode1 installation mode 12 installation mode 23 installation mode 3In the installation modes the LED are used in combination with the following parameters:LED readout installation mode 1Stand by D Kinner diameter in mmIntg c c-factor (entering digits after the decimal point)L.V.2 ΔP upper value of measuring span of the differential pressuretransducer in Pa (1 mbar = 100 Pa)This value must correspond to the setting on thedifferential pressure transducer. The D-FL 100-10 Displayrecalculates the numerical value of the differential pressurebased on this reference value and the current of thetransducer (e.g., 20 mA = 2000 Pa).L.V.1 m3/h volumetric measuring range in 1000 m 3 /hThis parameter is the reference value of the mA output. 20mA are emitted as soon as this gas flow value is reached.Display ρ gas density at standard operating conditions in kg/Nm³Error T operating temperature in °CGmbH
