3-6 Connection with Displacement Sensor

If the distance between the marking surface to the laser marker attaching surface is changing, the work distance can be
controlled at the time of trigger input according to the measured value if you connect the displacement sensor to the laser
marker.
When not using the displacement sensor, install the attached displacement sensor input connector to the back of the laser
marker connector to disable this function.

Connect sensor 0V and the analog ground. Terminals 1, 5 and
6 are internally connected.
Connecting the error output of the sensor to this terminal
allows that the laser marker outputs the warning of the sensor
error when the displacement sensor trigger is input while the
shutter is opened. When not using the displacement sensor
error signal, connect this terminal to GND.
During this input is ON status, "SENS ALRM" LED on the back
side of the controller lights up.
When it continues to be ON for 500 μsec. or more, the
displacement volume is imported to the laser marker at the
input ON edge.
During this input is ON status, "SENS TRG" LED on the back
side of the controller lights up.
This is the power for running the sensor.
Connect the sensor power supply terminal (+V side). Be sure
that the output current does not exceed 500 mA.
Connect sensor 0V and the analog ground. Terminals 1, 5 and
6 are internally connected.
This is the terminal for displacement volume input.
Connect the analog current output of the displacement sensor.
Do not connect externally.
Input common for the terminal No. 3: Trig. Connect to the
power source such as PLC for input of the displacement sensor
trigger. This terminal is not connected with IN COM of the I/O
terminal and I/O connector.
