    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 36: Transducer Requirements

    CD/USB Flash Drive To install Transducer Control 5 from a CD or USB Flash Drive: 1. Insert the Sensor Technology Installation CD into your CD-ROM drive, or plugin the USB flash drive. If the install loader doesn’t run, use Windows Explorer to navigate to the CD-ROM or flash drive, then run autorun.exe.

  • Page 37: Running Transducer Control & Connecting To A Transducer

    3. Run the Transducer Control program by clicking on the ”Start”/”Windows” button, then “Sensor Technology” > “Transducer Control 5”. When Transducer Control starts the “Search for connected transducers” dialog box will be displayed.
  • Page 38 Transducer Control 5 User Manual (RWT3746IM) The options prefixed with “AUTO” will search for multiple transducers, whereas the other options will search for a single transducer on a specific port. AUTO ETHERNET AUTO ETHERNET looks for network connected transducers. It does this by sending a broadcast packet on the configured port for all connected network interfaces.
  • Page 39 Transducer Control 5 User Manual (RWT3746IM) Ethernet Search Parameters The “Ethernet Search Parameters” dialog adds known hosts to the search list, as well as configure the broadcast port. Network Broadcast – UDP Port The UDP port configures the port on which broadcasts are sent, as well as the default port used with hosts specified without a port IP/HOST The IP/HOST list is a custom list of hosts added by the user.

    Transducer Control 5 User Manual (RWT3746IM) Firmware Upgrade If a firmware upgrade is available, Transducer Control may show an upgrade notification. The Ethernet Module may run in legacy mode if an old version of firmware is used. The transducer is in a vulnerable state while flashing the firmware, please ensure all the cables and power supply are trusted and properly connected.

  • Page 43 Transducer Control 5 User Manual (RWT3746IM) Save Click the “Save” button to update the Ethernet Module. The update may take a few seconds to complete, especially if updating via USB. If Transducer Control is connected via Ethernet, the new settings won’t take effect until the Ethernet Module is power cycled.

  • Page 44: User Configuration

    Transducer Control 5 User Manual (RWT3746IM) 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 45 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 46 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 47 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...

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

  • Page 51: 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. Auto Reset The Auto Reset settings control the Peak Torque Auto Reset value. Auto reset is a method of storing a peak value until a reset condition is met.
  • Page 52 Transducer Control 5 User Manual (RWT3746IM) Reset Dead Band The Reset Dead Band is a ± band around zero, and is specified as a percentage of FSD. The dead band is a band where the “Reset Hold Time” will not be applied. The band relates to the Auto Reset value, and not the reset point.
  • Page 53 Transducer Control 5 User Manual (RWT3746IM) Filters The torque and speed filters provide data smoothing for conditions where there may be erratic torque and speed readings. The filters apply to the base data captured and will affect both the digital and analog outputs. Enable or disable the filter for torque or speed by clicking on the appropriate “Filter Enabled”...
  • Page 54 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 55 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 56 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 57 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 58 Transducer Control 5 User Manual (RWT3746IM) 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. If an error is detected, an onscreen prompt will notify the user and direct them to a resolution.

  • Page 59: Zero Offset

    Transducer Control 5 User Manual (RWT3746IM) Zero Offset The Zero Offset feature sets a fixed torque offset value. The Zero Offset can be used to remove any offset that may have been introduced from its mechanical installation, or from idle torque present. It must be stressed that the zero offset is no substitute for correct installation.
