3. The descriptions of the signal contents

BCD output Pin No.1 to 20
Positive/negative logic change 5-digit parallel output
Open collector output

The bit switch 3 shown in the following figure <18> can change the logics, ON is for negative logic and OFF is for positive logic.

 

 

Pass-fail decision result output

○ Pin No. 21 (LOWER output):
     ON when LOWER set value ≥ Measurement value
○ Pin No.22 (OK output):
     ON when LOWER set value < Measurement value < UPPER set value
○ Pin No.23 (UPPER output):
     ON when UPPER set value ≥Measurement value

Open collector output

 

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

Open collector output
○ When Bit switch 3 is set to ON to select the negative logic.

Measurement value is positive (+) Pin No. 25: ON (Low level)
  Pin No. 26: OFF (Hi level)
 Measurement value is negative (-) Pin No. 25: OFF (Hi level)
  Pin No. 26: ON (Low level)
 RESET Pin No. 25: ON (Low level)
  Pin No. 26: OFF (Hi level)

 

  • ○ When Bit switch 3 is set to OFF to select the positive logic, above Pin No. 25 and No. 26 polarity outputs ON/OFF are all reversed.

 

Decimal point output
Pin No. 27 (D.P 3, when selected the minimum measurement unit as 10 µm)
Pin No. 28 (D.P 4, when selected the minimum measurement unit as 1 µm)
Open collector
○ When Bit Switch 3 is set to ON to select the negative logic.

 

Bit switch 1 is ON and selected 1 µm Pin No. 27: OFF (Hi level)
  Pin No. 28: ON (Low level)
Bit switch 1 is OFF and selected 10 µm Pin No. 27: OFF (Hi level)
  Pin No. 28: ON (Low level)

 

○ When Bit switch 3 is OFF setting to select the positive logic, No. 28 polarity outputs ON/OFF are all reversed.

 

Error output Pin No. 30
Open collector output
When miscounting occurs in the counting circuit of the counter, the ON signal is output which is continued until reset.

 

HOLD input Pin No. 31
When a low level voltage signal is input, the displayed value and BCD output data are held and the print command signal is output. While the low level signal is input, the HOLD state is continued. However, counting is still operated in the counting circuit according to the input signal from the gauge sensor while the HOLD state is retained. Therefore, when the HOLD state is released, the displayed value and BCD output data are changed to a value measured at that time.

 

RESET input Pin No. 32
When a low level voltage signal is input, the displayed value BCD output, error indication, and error output are reset. While the low level signal is input, the RESET state is continued.

 

BUSY input Pin No. 33
Same as HOLD input. Using for the timing when the external devices (printer or more) are in use.

 

COMPARATOR GATE output Pin No. 34
When a low level voltage signal is input, the pass-fail decision is forcedly stopped to set all decision result outputs to OFF.

 

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