Digital Gauge Frequently Asked Questions

For details, please refer to the instruction manual.

To capture BCD signals into a sequencer or similar device, please ensure to hold the signal with a hold signal.
For connections with external devices, it is the same as the DG-4240, so please refer to DG4240 BCD receiving side recommended circuit.

Explanation of signal content

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

You can switch the bit switch 3 below <18> to negative logic when on and to positive logic when off.
BCD output, polarity output, and decimal point output can be switched to positive/negative logic.

 

 

• Judgment output
  Pin No. 21 (Preset Out 1 output)
  Pin No. 22 (Preset Out 2 output)
  Pin No. 23 (Preset Out 3 output)
  Pin No. 24 (Preset Out 4 output)
  Open collector output

Setting polarity = measurement polarity and
| set value | ≦ | measured value | will be on.

 

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

• Turn on bit switch 3 and if negative logic is selected.

•  

-	No.25 (+ output)	No.26 (− Output)
When the measured value is positive (+)	on (low level)	off (high level)
When the measured value is negative (-)	off (high level)	on (low level)
at the time of reset	on (low level)	off (high 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)
• When bit switch 3 is turned off and positive logic is selected, the on/off states for items no. 27 and 28 will be reversed.

 

(5) 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 low-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 a low level. However, even during the hold state, the counting circuit continues to operate based on the input signal from the gauge sensor, so when the hold is released, the displayed value and BCD output data change to the measurement at that moment.

 

(7) Reset Input Pin No. 32

When a low-level voltage signal is input, the display value, BCD output data, error display, and error output are reset. This reset state continues while the signal remains low.

 

(8) BUSY Input Pin No. 33

It is in the same state as hold input. It is used for timing with external devices such as printers.

 

(9) 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.
