    How to correct Error Code 222 on Milltronics ACCUMASS BW500?
    • Z
      zschwartzSep 9, 2025
      Error Code 222, 'Zero out of range', indicates that the zero deviation is greater than the minimum limit. Consider performing an initial span (P388).
  • C
    Caleb FordSep 7, 2025
    What should I do if my Milltronics ACCUMASS BW500 shows Error Code 211?
    • D
      Douglas LeonSep 7, 2025
      Error Code 211, 'Remote Totalizer 2 exceeded', suggests that you need to increase the resolution.

    Why does my Milltronics ACCUMASS BW500 show Error Code 212?
    • H
      Hannah WolfeAug 22, 2025
      Error code 212 indicates that the speed is more than twice the design speed. To resolve this, check the design belt speed, actual belt speed, and speed constant. If necessary, perform a speed constant adjustment (P018).

    How to troubleshoot Error Code 221 on Milltronics ACCUMASS BW500?
    • N
      Nicole DuncanSep 2, 2025
      Error Code 221, 'Span out of range', indicates a span deviation greater than 12.5%. Consider performing an initial zero (P377).
  • C
    Christopher BakerSep 1, 2025
    What to do for Error Code 241 on Milltronics ACCUMASS BW500?
    • S
      Sarah WrightSep 1, 2025
      Error Code 241, 'No PID mA Input', happens when the PID Process Value Source (P402) or PID Setpoint (P414) is programmed for a mA Input, but the mA Input Function (P255) isn't programmed correctly.
  • E
    Elizabeth TravisAug 31, 2025
    Why does Milltronics Industrial Electrical display Error Code 220?
    • M
      Michelle WrightAug 31, 2025
      Error Code 220, 'Span Too Low', indicates that the span is less than 1 mV. Ensure the proper test weight or chain is applied during the span.
  • M
    Michele HortonAug 30, 2025
    What does Error Code 213 mean on Milltronics ACCUMASS BW500?
    • P
      Paul BurtonAug 30, 2025
      Error Code 213, 'Maximum rate exceeded', means the rate is more than three times the design rate. If there's no mechanical issue, check if re-rating the design rate is needed.
  • R
    Richard JohnsonAug 28, 2025
    How to resolve Error Code 205 on Milltronics ACCUMASS BW500?
    • D
      David OrozcoAug 29, 2025
      Error Code 205 indicates that a zero or span calibration is required.
