Signal Name and Function
A1 : Load Digital Zero Performs digital zero for a load value on the ON edge.
However, the digital zero function is not available if the current load value exceeds the
“zero limit setting” when the “zero balance” value of a load sensor calibration is set as
zero.
A2 : Displacement Position Adjustment
Presets a value of “Displacement Position Adjustment” (set by selecting “SENSOR
CAL.”→”DISP.”(horizontal axis)→”DISP.VOLT/DISP.PULSE” to the counter
(Default: 0.0 mm) on the ON edge.
A3 : Measurement Start/Stop
Typically, measurement is ready on the ON edge and measurement is terminated on
the OFF edge.
An actual measurement is started based on the conditions for starting/stopping the
measurement which are set on a work-by-work basis.
A measurement can be started based on either (1) the start signal or (2) a combination
of the start signal and load values.
A measurement can be stopped in the same fashion.
A4 : Hold Command (Displacement)
Functions as a displacement value hold timing contact signal. During “Displacement
Sample Hold,” holds and judges the displacement value at the ON timing.
However, when a signal makes an ON-OFF-ON transition, the displacement value is
held at the first ON timing of the measurement.
Indication of load and displacement values is also held, but the waveform (data)
continues to be displayed.

A5 : Hold Command (Load)
Functions as a load value hold timing contact signal. During “Sample Hold”, holds
and determines the load value at the ON timing.
However, when a signal makes an ON-OFF-ON transition, the load value is held at the
first ON timing of the measurement.
Indication of load values is also held, but the waveform (data) continues to be
displayed.
A6 : Reset Used to abort all the current operations, regardless of whether they completed
successfully or not, and discard the measurement data, if errors or other abnormal
conditions occur.
The indicator will return back to the state it was when last powered on (The settings are
retained).
A7 : Displacement-Sensor Power Supply
+5 V output terminal of displacement-sensor power supply (Maximum: 500 mA)
A8 : Displacement-Sensor Power Supply (COM)
COM terminal of displacement-sensor power supply
A9 (LL) : Load Judgment Output
A10 (LO) Compares a load value held in each hold mode with the load judgment values to
A11 (GO) produce a NO/GO result, during measurement.
A12 (HI)
A13 (HH)
A14 (LO) : Displacement Judgment Output
A15 (GO) Compares a displacement position value when a load values is held in each hold mode
A16 (HI) with the displacement judgment values to produce a NO/GO result.
B1: (Work Select 1) External entry of a work number. It is necessary to set this entry prior to A3
B2 (Work Select 2) “Measurement Start/Stop.”
B3 (Work Select 3) Note that this entry is available only if “SETTINGS”→”WORK INPUT”→”EXT INPUT”
B4 (Work Select 4) is chosen.
B5 : External Judgment Reset
Resets a Load Judgment Output (A9, A10, A11, A12, A13, A14, A15, A16).
Resets the load judgment output of a hold value and switches to continuous judgment
output when continuous judgment is “enabled.”
Hold and judgment indications in the screen remain unaffected.
B6,B7,B8,B9 : Signal COM
COM (common) terminal for input/output signals.
B12 : Judgment Completed
Available in a Hold mode which uniquely determines a load hold point, such as Sample
Hold. Turns ON when the Hold mode is completed. Turns OFF when a new
measurement start/stop signal is received.
B13 : Measurement Completed
Turns ON when measurement is completed and data is stored in CF.
Now ready for a new measurement.
Pin No. 9, 11 (+12 V OUT) of the sensor signal input connector and pin
No. A7, A8 (displacement-sensor power supply +5 V) of the control
signal input/output connector cannot be used together at once.
