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 <18> can be switched to negative logic when on and to positive logic when off.

  • Pass/Fail Judgment Output
    Pin No. 21 (LOWER output) ON when LOWER setting value ≧ count value
    Pin No. 22 (OK output) ON when LOWER setting value < count value < UPPER setting value
    Pin No. 23 (UPPER output) ON when UPPER setting value ≧ count value
    Open collector output

 

  • Polarity output Pin No.25 (+ output), No.26 (- output)
    Open collector output
  • Set Bit Switch 3 to on, and if selecting 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)
  • When Bit Switch 3 is turned off and positive logic is selected, the on/off states for items No. 25 and 26 above 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
  • When bit switch 3 is turned on and negative logic is selected,
    if bit switch 1 is turned on and 1μm is selected: No.27: off (Hi level), No.28: on (Low level)
    If bit switch 1 is turned off and 10μm is selected: No.27: off (Hi level), No.28: on (Low level)
  • If you turn off bit switch 3 and select positive logic, 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 maintains the hold state while it is at Lo level. However, even during the hold state, the counting circuit internally 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 is in the same state as the hold input. It is used for timing of external devices such as printers.

  • Comparator Gate Output Pin No. 34
    When a low-level voltage signal is input, the pass/fail judgment is forcibly stopped, and all pass/fail judgment outputs are turned off.

  • 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.
