TIC-LF470B3Communications output ：• HART (std.) — Digital signal is superimposed on4–20mAdc current signal as follows:Conforms to HART protocolLoad resistance: 240 to 750ΩLoad capacitance: 0.25μF maximumLoad inductance: 4mH maximum• PROFIBUS(opt.)Protocol: PROFIBUS-PABaud rate: 31.25kbpsBus voltage: 9-30VDCConsumption electric current of bus: less than 16mAManufacture Ident-No.: 093BHEXStandard Ident-No.: 9740 HEXSlave address: 0-126 (Default address is 126)Profile: Profile Ver.3.01 for Process ControlDevicesFunction blocks: AI(Flow)×1 , Totalizer×1LCD display:Full dot-matrix 128×128 dot LCD display(back–light provided)The data on the LCD inside the converter can rotateto 90, 180, and 270 degrees by a software, withoutrotating the indicator itself. (Combined type only)Parameter settings — Parameters can be set asfollows:• IR Switches: Three key switches are provided toset configuration parameters.• Digital communication: The AF900 hand-heldterminal or PROFIBUS is needed to setparameters.• Zero adjustment: Zero point adjustment can bestarted by pressing the switch in the converter.• Damping: 0.5 to 60 seconds (selectable in onesecond increments)“Field re-verification” Mag-Prover – Toshiba’sZero span calibration tool allows unit to bere-calibrated and verified using an internal softwareprogram. (For more information contact ToshibaInternational Corp.)Conditions when power fails:Parameter setting values are stored in non–volatilememory and the values will be restored when thepower returns to normal condition. The outputs anddisplay will remain as follows when power fails.• Current output: 0mAdc• Digital output: OFF• LCD display: No display• PROFIBUS: No communicationPower supply:One of the following can be selected:• 100 to 240Vac, 50/60Hz (std.)(allowable voltage 80 to 264Vac)• 24Vdc (allowable voltage 18 to 36Vdc)• 110Vdc (allowable voltage 90 to 130Vdc)Surge protection:Arresters are installed in the power supply and acurrent signal output circuit to help protect the meterfrom lightning and improve personnel safety.Case: Aluminum alloy (equal to IP 67)Coating: Acrylic resin-baked coating, pearl–graycoloredCable connection port:Cable glands —Provided as standard, OD of 11 to 13mmMaterial Nylon 66G (PF) 1/2 male screwsApplicable diameter —0.433 to 0.512 inch (11 to 13mm)Note: When PROFIBUS option is specified, cable gland size is φ6～8mm for signal cable, φ11～13mm for power cableVibration resistance:No resonance to the following levels of vibration:• 10 to 150Hz with acceleration of 9.8m/s2• Vibration of 30Hz with 29.4 m/s2 in 4h in eachdirection will not cause any defect to unit.Note: Avoid using the flowmeter in an environment withconstant vibration.Dimensions :See Figure 5MTBF:Converter: 220,000 hours (25 years) at 77 °F (25 °C)based on strict military specificationMIL-HDBK-217FDetector: 350,000 hours (40 years) at 77 °F (25 °C)based on strict military specificationMIL-HDBK-217F
