    Transducer Control 5 User Manual (RWT3746IM) Introduction Transducer Control is an all-round application to unlock the advanced functionality of the ORT/RWT Series Transducers. Transducer Control enables the user to exploit the flexibility of the advanced transducer series by configuring the run time parameters of the transducer to best suit their application.

  • Page 34: Installation

    Transducer Control 5 User Manual (RWT3746IM) Installation To install Transducer Control 5: 1. Insert the Sensor Technology Installation CD into your CD-ROM drive. The following screen will be displayed. 2. Click the ‘Install’ button next to “Transducer Control 5”. 3. Follow the onscreen instructions.

  • Page 35: Running Transducer Control & Connecting To A Transducer

    2. Connect the transducer to the computer using either RS232 or USB. 3. Run the Transducer Control program by clicking on the ”Start”/”Windows” button, then “Programs”/”All apps” > “Sensor Technology” > “Transducer Control 5”. When Transducer Control starts the “Search for connected transducers” dialog box will be displayed.
  • Page 36 Transducer Control 5 User Manual (RWT3746IM) The options prefixed with “AUTO” will search for multiple transducers, whereas the COMx options will search for a single transducer on a specific port.

  • Page 38: Transducer Configuration

    Transducer Control 5 User Manual (RWT3746IM) Transducer Configuration User Configuration Analog Setup The “Analog Setup” tab of the user configuration allows the user to configure the transducers analog outputs. All transducers have dual analog outputs with equal capability on both. Analog Data Select The Analog Data Select section allows the user to assign an internal data variable to the output, and select a data range to be applied to the Analog Voltage Scaling.
  • Page 39 Transducer Control 5 User Manual (RWT3746IM) Torque – Peak Peak torque value captured since the last reboot or reset. Torque – Auto Reset Peak torque value captured since the last reboot or reset. Auto Reset mode automatically resets the peak torque when the current torque drops below a percentage of the peak value.
  • Page 40 Transducer Control 5 User Manual (RWT3746IM) Data Ranges The data range parameters control how data from the selected internal variable is taken and scaled. This feature is useful when the user is working in a specific measurement area and requires a greater change in analog output. The low and high range values effectively rescale to the Zero and FSD voltages set in the Analog Voltage Scaling section.
  • Page 41 Transducer Control 5 User Manual (RWT3746IM) The following graphs illustrate some examples of how the range selection works. Torque (100Nm FSD), Standard Range (0 Nm - 100 Nm), ±10v Scale.  +10V -10V +100Nm -100Nm Zero Torque  Torque (100Nm FSD), User Defined Range (50 Nm - 100 Nm), ±10v Scale. +10V -10V +100Nm...
  • Page 42 Transducer Control 5 User Manual (RWT3746IM) Range effects on resolution The range selection will in no way effect or increase the resolution of the transducer. The value expansion is artificial and aids only to give the user a greater change in analog output value.

The text boxes to the right of the respective slider bars will display the configured voltage.

  • Page 45: Digital Setup

    Transducer Control 5 User Manual (RWT3746IM) Digital Setup The “Digital Setup” tab of the User Configuration allows the user to control some of the operational parameters that effect the processing and output of data. Filters The torque and speed filters provide data smoothing for conditions where there may be erratic torque and speed readings.
  • Page 46 Transducer Control 5 User Manual (RWT3746IM) Limits The limits feature allows the user to configure the transducer to control external processes based on predefined operational parameters. Control is accomplished via an open collector output on the transducers analog connector. There are numerous ways this feature could be utilised, some examples include, system shutdown on overload or triggering a conveyor belt when a nut/bolt has been tightened to the correct torque.
  • Page 47 Transducer Control 5 User Manual (RWT3746IM) To enable Limits click the “Enable Limits” checkbox. Channel Select The “Channel Select” option selects the control channel to be used with the limits feature. The user can select between torque and speed. Output Mode The “Output Mode”...
  • Page 48 Transducer Control 5 User Manual (RWT3746IM) If torque is selected as a control channel then the slider will be scaled from –FSD (counter clockwise full-scale) to +FSD (clockwise full-scale) in increments of 1% of FSD. If speed is selected as a control channel then the slider bar will be scaled from 0 to FSD in increments of 1% of FSD.
  • Page 49 Transducer Control 5 User Manual (RWT3746IM) Misc RS232 The RS232 settings control the RS232 functionality of the connected transducer. Baud Rate The baud rate option selects the RS232 transmit and receive rate for the connected transducer. It is recommended that the user select the fastest mode possible (115200bps), as lowering the speed will reduce the throughput and add latency to programs interrogating the transducer.
  • Page 50 Transducer Control 5 User Manual (RWT3746IM) when the current torque value drops below the “Reset Percentage” of the stored peak value. To configure the percentage, use the slider bar to select a value between 5% and 95%. Update Transducer The “Update Transducer” button will upload the settings to the Transducer. Transducer Control will validate the settings before transmission to ensure that there are no errors.
