Page 5: General Information
The HVG-2020A is designed for quick, easy installation and will provide the user with long lasting, trouble free, reliable vacuum measurement. The electronics can be powered by a power supply capable of delivering any voltage between 12 VDC to 36 VDC. -
Page 6: Features
GAS INDEPENDENT. The piezo-resistive sensor is media isolated and provides a direct pressure measurement that is gas species independent. 300 SERIES STAINLESS STEEL. The vacuum envelope of the HVG-2020A is entirely 300 series stainless steel with welded construction. Using metal seal vacuum connections eliminates the permeation, degradation and outgassing problems of elastomer O-rings. -
Page 7: Specifications
WARNING: Do not power with isolated drive circuits that are more than 36 volts above ground potential or could reach 36 volts in the event of a fault. Failure to heed this warning could result in serious personal injury and/or damage to the equipment. Page 7 of 29 HVG-2020A Instruction Manual... -
Page 8: Accessories
A separate 24VDC power supply (P/N 12-01-169) is also available without display. 1.3.2. Cables The HVG-2020A instruments come with a 9 pin D-connector. A Hastings cable (Part # CB-AF-8-HVG9M) is available to interface with the standard 15 pin D-connector found on Hastings power supplies. Cables are available from Hastings in various lengths as well. -
Page 9: Installation And Setup
NOTICE: The gauge should be installed in a clean and careful manner. Take care not to drop the product and avoid impacts to prevent damage. The HVG-2020A gauge may be mounted in any position, though care should be taken to prevent objects, particles or condensate from dropping inside the gauge if mounted upside down. -
Page 10: Electrical Connections
The HVG-2020A can come with any of several vacuum connections, including: 1/8” NPT, ¼ VCR, ½” VCR, KF- 16, KF-25, 1.33” CF, 2.75” CF and ½” smooth stub tube. The tube is configured with the vacuum fitting requested. NOTICE: When installing the 1/8” NPT version, be certain to use the ½” wrench flats. Do not tighten using the aluminum housing as a grip or damage may result. -
Page 11: Setpoints
2.3.4. Setpoints The HVG-2020A has two open-drain setpoints available on the 9 pin D connector. The Hi setpoint will be active when the pressure is above its set value and the Lo setpoint will be active when the pressure is below its set value. -
Page 12: Serial Connection
The default port set-up is 19.2K baud, 8 data bits, 1 stop bit, no parity and no flow control. A “carriage return” signals the end of command input. The end of a response message from the HVG-2020A is signaled by a “>”... -

Page 15: Display Operation
3. Display Operation General The HVG-2020A has an optional color touch screen module that can be assembled with the internal I/O module to provide the user with local control over device operation. All operations done via the touch screen utilize the values associated with the digital lists and commands found in Section 4. -

This selection allows the user to reset the configuration of the gauge back to its original factory setup. A warning screen will appear asking if the user is certain they want to perform this operation. Page 17 of 29 HVG-2020A Instruction Manual... -
Page 18: General Operation
Positive Pressure Operation WARNING: The HVG-2020A does not have a high-pressure option and is only rated for a maximum operating pressure of 20 PSIA. Using the instrument above its rated maximum overpressure of 40 PSIA (25 PSIG), could result in damage to the instrument or alter its behavior. -

5.2.4. Command Prompt The prompt character is a greater than symbol ‘>’ (x3E); when this symbol is received, the HVG-2020A is ready to accept a new command. Software can use the prompt as an end of response indicator if this symbol is not used in any text fields (e.g. -

S5 of the target device. As an example, if you want to read the Sensor List from the device with address 0x02, send the command *02 SL. The HVG-2020A will accept a one-digit address, but this could cause problems; *2 SL will work the same as *02 SL, but *2 A will be interpreted as *2A which is addressing device 2A, not 2. -

(0x99) will be suppressed. The S5 command is an exception to this rule; when the device is the only HVG-2020A on the bus, the command *99 S5 can be used to get the device’s address. Other than the above behavior, responses will be no different than responses in RS232 mode. There will be no address in responses. - Page 22 Sets S15 UB Zero and S16 DB Zero to the current bridge power readings. The effect of this is the current pressure reading becomes the zero pressure point. Alias for ZERO For backward compatibility. Page 22 of 29 HVG-2020A Instruction Manual...
