Program Utility TPU_2.8.2 TriLIN Programming Manual
1. Programming the electronics a. Tool necessary Power supply 12-32 V DC Computer with appropriate USB port and a Windows Operating System (We recommend Windows 7 or higher) LPU software Programming cable Possibly a voltmeter (Amperemeter) for the new comparison of the analogue outputs and functional test b. Read-out from the electronics Supplying the electronics with voltage, connecting the programming cable and opening the software. "COM Port" tab and then choose an appropriate port from the list Reading out from the electronics with the help of the "Read EE" button. If the data is not read out correctly, the operation must be repeated. TrigasDM GmbH September 2016 2
c. Importing the calibration curve A Trigas calibration file "*.sav" is necessary for the programming Choose the option "Load F/V kcurve" in the "File" menu for temperaturecompensated programming (Frequency/Viscosity vs. K-factor) / Refer to Section 4.3. Choose optional "Load F kcurve" for non-temperature compensated programming (Frequency vs. K-factor). After the data has been reloaded, the serial number must be compared with that of the calibrated flow meter. Optional: Manual entry of the calibration curve is necessary only if the data is not available to you. NOTE The values must be entered with a dot as the decimal point separator. e.g. 15.45 instead of 15,46 d. Adjusting the electronics Cut-off (ms) Maximum waiting time for completing a signal period. If this time gets exceeded, no input signal gets detected and all outputs are set to zero. Update rate (ms) Measurement period before a measurement result is obtained and calculated. Special case: "0" means that the calculation is already taking place after one pulse. Recommendation: Cut Off = 2 Update Rate TrigasDM GmbH September 2016 3
Timebase (sec.) Time constant for conversion from the K-factor and flow units. o 1 = xxx/sec. o 60 = xxx/min. o 3600 = xxx/hour Minimum frequency (Hz) Lowest frequency (Leakage flow rate). Below the frequency, the TriLIN displays zero at all outputs. Crystal factor Correction factor for internal time base. Use Volts Input 0 PT100 Input 1 Analog Input (analog Temp.) TriLIN can use as temperature input PT100, or analog temperature signal 0-10V e.g. 0 10V = -20 120 C Attention! To use the input, please contact the manufacturer. Mode Operating mode of the electronics. Mode Compensation Analogue output Frequency output 0 UVC Volumetric Volumetric 1 None Volumetric Volumetric 2 UVC Mass Volumetric 3 None Mass Volumetric 4 UVC Volumetric Mass 5 None Volumetric Mass 6 UVC Mass Mass 7 None Mass Mass Version Should not be changed. Pt100 K-factor (bits to Ohm) K-factor of the PT100 input. Should be corrected only when determining deviations of temperature input. TrigasDM GmbH September 2016 4
e. Liquid data changes The data pertaining to the media can be corrected whenever desired. To do this, choose the option "Load Fluid" in the "File" menu in order to load the new data. The table can also be edited manually as an option. NOTE The values must be entered with a dot as the decimal point separator. e.g. 15.45 instead of 15,46 f. Scaling the outputs Frequency output You only assign the desired scaling in the fields. You can set the units with "Mode" and "Time Base". e.g.: Mode 0: Frequency output, volumetric Time Base 60 per minute Flow / Frequency 0-100 l/min. = 0-1000 Hz TrigasDM GmbH September 2016 5
Flow, analogue output Mode 0: Analogue output, volumetric Time Base 60 per minute 0-100 l/min. = 0-10 V (possibly 4-20 ma) Volts (bits) A/D value is calculated automatically Temperature, analogue output -50 150 C = 0-10 V (possibly 4-20 ma) g. Programming Press the "Write EE" button to program the electronics. After successful programming, the message appears: Attention! The period of time after pressing the "Write..." and the "Succes" message should be 3sec. If not, the process should be performed again. TrigasDM GmbH September 2016 6
Run Live After programming, the program enables the data to be checked. The Live mode is started by pressing the "Run Live" button. h. Saving data Save the settings in the "File" menu option with "Save All" (*.lin) If you need further information, please contact us. TrigasDM GmbH September 2016 7
i. Printing the data You need Excel 2010 or later to print the data. Open the Excel table enclosed. Confirm the security warning with "Activate contents" Load the saved data with the "Load LIN" button. Enter the serial number of the electronics. Print out the report. TrigasDM GmbH September 2016 8
2 Adjusting the analogue outputs NOTE The adjustment should be carried out only with a calibrated voltmeter or ammeter. Connect the electronics as you do for programming with the data cable and power supply. Connect the voltmeter (or ammeter) to the analogue output to be calibrated. Read out from the electronics with "Read EE". There are arrow keys and scroll bars located to the right side of the scaling fields with the help of which the bit values of the respective analogue outputs can be changed. With the upper scroll bar, you can set the minimum value on the multimeter (e.g. 0 V for 0-10 V), and then with the lower scroll bar you can set the maximum value (e.g. 10 V for 0-10 V). Press STOP at the end -> repeat this for the second output. Press the "Write EE" button to program the electronics. TrigasDM GmbH September 2016 9
3 Adjusting the PT100 input NOTE You should carry out this adjustment only with a calibrated resistance decade Connect the electronics as you do for programming with the data cable and power supply. Connect the decade at the temperature input and set 100 Ω. Read out from the electronics with "Read EE" Enter 100 in the calibration field and press the "Calculate" button The PT100 K- factor is recalculated. Press the "Write EE" button to program the electronics. TrigasDM GmbH September 2016 10

5 Trouble shooting 4.8.1 Electronics has no output signal a. Check supply voltage (9-32V DC) i. Standard current consumption is (depending on the configuration) up to 40mA. - Current > 100mA - board defective. - Current = 0 ma - electronics connected incorrectly. b. Flowmeter functionality check i. Attention! The turbine should not be tested with compressed air - turbine may be damaged. ii. Flow simulation: turbines pickoff evaluation Remove pickoff from the turbine and move an iron element (not stainless steel) under the pickoff back and forth. iii. Pickup Resistance Measuring - between pin 1 and 8 RF Sensor: 10Ω +/- 15% c. Check the condition of the electronics (if available) connect electronics with PC and RUN LIVE Switch Mode Programming - Point 4.4 4.8.2 Baseline value appears to be wrong a. If a problem is noted - RUN LIVE check mode. Compare Analog temperature output versus medium (liquid, gas) temperature. TrigasDM GmbH September 2016 12
