3.The descriptions of the signal contents
BCD output Pin No.1 to 20The bit switch 3 shown in the following figure <19> can change the logics, ON is for negative logic and OFF is for positive logic. Changeable outputs are BCD output, polarity output and decimal point.
Pass-fail decision result 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
ON when Setting
polarity = Measurement polarity,
and |Setting value|≤|Measurement value|
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, above Pin No. 27 and 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.
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.
