  • Open Circuit Diagnostic For Pulsed Solenoid I/P

  • US Patent:
    20210239233, Aug 5, 2021
  • Filed:
    Jan 31, 2020
  • Appl. No.:
    16/779409
  • Inventors:
    - Marshalltown IA, US
    Davin S. Nicholas - Bondurant IA, US
    Gregory R. Bulleit - Marshalltown IA, US
    Christopher C. Arnold - Grinell IA, US
    David L. Smid - Marshalltown IA, US
  • International Classification:
    F16K 31/06
    F16K 31/42
    F16K 27/02
  • Abstract:
    Techniques for diagnosing failures in a digital solenoid I/P converter are provided herein. A controller of the I/P converter may apply a fixed voltage to an I/P coil of the I/P converter, causing an armature to move from an off-position to an on-position in a properly-functioning I/P converter. The controller may receive an indication of whether a digital logic line trip has occurred, indicating that a current for the I/P coil has reached a desired maximum current level. The controller may remove the fixed voltage applied to the I/P coil when the maximum current level is reached or when a threshold period of time has elapsed from the application of the fixed voltage to the I/P coil. The controller may diagnose, based on whether the digital logic line trip occurred prior to removing the fixed voltage, a failure in the I/P converter.
  • Diagnostic For Pulsed Solenoid I/P Functionality

  • US Patent:
    20210239768, Aug 5, 2021
  • Filed:
    Jan 31, 2020
  • Appl. No.:
    16/778814
  • Inventors:
    - Marshalltown IA, US

  • International Classification:
    G01R 31/50
    F16K 37/00
  • Abstract:
    Techniques for diagnosing failures in a digital solenoid I/P converter are provided herein. A controller of the I/P converter may apply a fixed voltage to the I/P converter, causing an armature to move from an off-position to an on-position in a properly-functioning I/P converter. The controller may receive an indication of whether a digital logic line trip has occurred, indicating that a current for the I/P coil has reached a desired maximum current level, and an elapsed time from the application of the fixed voltage. The controller may compare the amount of time elapsed from the application of the fixed voltage to an expected amount of elapsed time from the application of the fixed voltage to the I/P coil after which a digital logic line trip will occur for a properly functioning I/P coil and diagnose, based on the comparison, a failure in the I/P converter.
