  • Page 5: General Information

    HVG-2020 Vacuum Transducer. The THCD-101 is a single channel unit which can be used to power a bipolar (±15Vdc @ 300mA) or unipolar (24Vdc @ 400mA) device. The THCD-101 can display the output from a transducer that supplies voltage signals up to 10 VDC or 4 –...

  • Page 6: Features

    Dual Programmable Alarms with Relays. The THCD-101 provides two double throw relays with 2A (@30 Vdc) switching capacity and 220Vdc max switching voltage. USB, Ethernet and Analog Output (Standard). The THCD-101 has multiple ways to provide the user with a remote indication of the controlled parameter.

  • Page 7: Accessories

    Hastings offers power supplies that convert 100, 115 or 230VAC to the 24Vdc voltage required to operate the THCD-101 and have a circular power plug that will mate with the power jack on the back of the THCD-101. 24VDC power supply (P/N 12-01-169).

  • Page 8: Installation And Setup

    Mechanical Connections 2.2.1. Mounting NOTICE: The THCD-101 should be installed in a clean and careful manner. Take care not to drop the product and avoid impacts to prevent damage. The THCD-100 can be panel mounted, or used on a bench top and is a standard 96 x 48mm panel meter enclosure.

    USB-C 3.1 cable will not provide SuperSpeed functionality, although the cable will still work as per the USB 2.0 specification. When connected via the USB port, the THCD-101 will emulate a standard serial port. The fixed baud rate is 57600 with other settings as follows: 8 data bits, 1 stop bit, No parity, No handshaking.

  • Page 11: Operation

    The full-scale analog signal input value is configurable via front panel menu for any value from 0 to 10 Vdc (20 mA for 4 – 20 mA units). The THCD-101 will show the over-range error (“RANGE”) when the analog input is more than 15% over the full-scale analog value.

    This would mean isolating flow devices or fully pumping a pressure device. Note that the user communicating with the THCD-101 unit remotely using the USB or Ethernet communication ports can also clear a previously entered user re-zero value. This should be used before any input calibration is performed to ensure that the calculated calibration points are not distorted by the user zero offset.
  • Page 13 (d) Main Menu Screen The Main Menu screen allows the user to select screens that are used for the configuration of the THCD-101 – the setpoint (initial value, initial mode, source), input (range, full scale, units string), comms, filtering and relays can all be configured from screens selected via the main menu.
  • Page 14 (f) Input Screen This screen allows you to change the input channel range and full-scale voltage and assign a units label (up to 5 characters) for the channel data. The number of decimal places selected on the range field dictates the number of decimal places shown for the input channel data on the Main screen.
  • Page 15 If Factory Defaults is selected from the Main Menu, this screen appears to ask for confirmation of the requested function. If confirmed then the screen changes to show a percentage of completion of the factory defaults and once completed the THCD-101 will restart. Switch Functions:...

    4. Remote Communications Webserver 4.1.1. Main page The Web server can be used by entering the IP address of the device into a browser address bar. This allows the user control of various settings within the device and to read the devices current reading. Along the top are a series of tabs to allow the user to switch to various sections of device control.

  • Page 17: Control Configuration Page

    TCP/IP communication requires an IP address and subnet mask to be configured for the THCD-101. This can be set via the front panel. Note that after changing the IP address or subnet mask, the THCD-101 must be re- initialized by performing a system reset. This is done automatically if setting the IP values using remote communications or the webserver, but if the IP values from the front panel, you must power off &...

  • Page 18: Command/Query Format

    (a) Output current readings – ‘r’ This command tells the THCD-101 to get the current reading of the input channel data and send it to the communications channel. If the input voltage is more than 15% over the full scale voltage, the <reading> below will be replaced with the over range error –...
  • Page 19 As with the value, the setpoint mode set using the ‘spm’ command (above) is a volatile setting. Again this command provides a way of setting an initial startup mode for the setpoint on power up of the THCD-101. It takes one parameter which is a number between 0 & 2, identifying the initial mode, as follows:...

    4 octet IP address. e.g. 192.168.1.180. The max octet value is 255. If a greater value is entered, that value will be capped to 255. Once the THCD-101 has responded to the command, it will display the following and autorestart the system.

  • Page 21: Filtering Commands

    (c) Input channel full scale – ‘uif’ This command is used to set the full-scale voltage for the input channel. The single parameter is the actual full-scale value. The full scale voltage setting for the input channel is retrieved using the query ‘uif?’. The data returned is as follows: INPUT FULLSCALE: <fs>...

    To perform a user input rezero function, use this command. Typically the command takes no parameters to perform the function, although it can take an optional parameter of ‘0’ which clears any value already generated by a previous rezero. To find the current user rezero value use the query ‘irz?’. The data returned is as follows: REZERO: <rezero>...

    5. Troubleshooting Authorized Maintenance With proper care in installation and use, the pressure gauge will require little or no maintenance. If maintenance does become necessary, it is best to consult the factory before doing so, since some procedures may require recalibration. Entry into the gauge or tampering with the printed circuit board will void the warranty.
