Measuring Gas Velocity with the D-FL 100 Differential Pressure Bar

D−FL 100 Seite 235.3. Error Messages on the D-FL 100-10 DisplayThe D-FL 100-10 Display puts out the following error messages on the display:Displayed error Cause of error SolutionE-01 The absolute pressure transmitterputs out a signal less than 3.8 mA.E-02 The temperature transmitter puts outa signal less than 3.8 mA.E-04 The differential pressure transmitterputs out a signal less than 3.8 mA.E-08 The current entering at the input ofthe differential pressure (absolutepressure or temperature) transmittermeasures more than 20 mA.Check connections and connectingwires. Calibrate transmitter ifnecessary.Check connections and connectingwires. Calibrate transmitter ifnecessary.Check connections and connectingwires. Calibrate transmitter ifnecessary.Check transmitter and calibrateanew if necessary.E-16 Defective RAM Restart unit and replace RAM-IC ifnecessary (DURAG service).E-32 Spill: the gas velocity is too high. Increase gas velocity measuringrange (see Section 5.2: Start-up,turn turning knob at setting 1, valueat L.V.1)E-64 EEPROM transmission error Restart unit and replace EEPROM ifnecessary (DURAG service).FEHLThe turning knob is switched to anillegal position ( > 3)Check the position of the turningknobThe displayed error number is the sum of all actual errors, e.g. E-05 means: E-01 and E-04.During these error messages, a signal of 2 mA of current is read at the output of theD-FL 100-10 Display.6. Recording of Measured DataThe D-FL 100-10 Display puts out the present measured data as an analog electrical signal. Accordingto industry standards, there should be a continuous recording of measured values. The following stripchart recorders are recommended: recorders of 0-20 mA with recording width of at least 100 mm. Thelive zero point of the display is at 20% (4 mA) of the recording scale.The measurements and status signals may, however, also be evaluated by an emission computerdownstream.GmbH
