Explanation of signal content

 

  • BCD output Pin No. 1-20
    Positive/Negative logic switch 5-digit parallel output
    Open collector output

The bit switch 3 below <8> can be switched to positive logic when on and negative logic when off.

    • Polarity output Pin No.25 (+ output), No.26 (- output)
      Open collector output

    • Turn on bit switch 3 and select negative logic
      When the measurement is positive (+): No.25: on (Low level), No.26: off (Hi level)
      When the measurement is negative (-): No.25: off (Hi level), No.26: on (Low level)
      During reset: No.25: on (Low level), No.26: off (Hi level)
  • If Bit Switch 3 is turned off and positive logic is selected: the on/off states of the above No. 25 and 26 will be reversed.

 

Decimal point output
Pin No. 27 (D.P3, minimum measurement unit 10μm selected)
Pin No. 28 (D.P4, minimum measurement unit 1μm selected)
Open collector output


  • Turn on Bit Switch 3 and select negative logic

    When Bit Switch 1 is on and 1μm is selected: No.27: off (Hi level), No.28: on (Low level)
    When Bit Switch 1 is off and 10μm is selected: No.27: off (Hi level), No.28: on (Low level)
  • If Bit Switch 3 is turned off and positive logic is selected: the on/off states for items 27 and 28 above will be reversed.

 

    • Error Output Pin No. 30
      Open collector output
      If a miscount occurs in the counting circuit of this device, an on signal will be output. The on signal will continue until it is reset.

    • Hold Input Pin No. 31
      When a Lo level voltage signal is input, the displayed value and BCD output data are held, and a print command signal is output.

      This signal will maintain the hold state while it is at a Lo level. However, even during the hold state, the counting circuit inside continues to perform counting operations based on the input signal from the gauge sensor, so when the hold is released, the displayed value and BCD output data will change to the measurement value at that moment.

    • Reset Input Pin No. 32
      When a low-level voltage signal is input, the displayed value, BCD output data, error display, and error output are reset. The reset state will continue while this signal is at a low level.

    • BUSY input Pin No. 33
      It has the same function as the hold input. It is used for timing external devices such as printers.


  • Print command output Pin No. 35
    Open collector output
    When the hold signal or BUSY signal is input, and the displayed value and BCD output enter the hold state, a negative pulse print command signal is output.
