Wiring Input/Output Cables

The input/output cable has the following wires.
Wire the cable correctly. Incorrect wiring may damage the Smart Sensor.
(1) A 12- to 24-VDC (±10%) power supply is connected to the power supply terminal.
When using an Amplifier Unit with a PNP output, the power supply terminal is also
the common I/O terminal for all I/O except for the linear output.
Use a stabilized power supply separate from other devices and power systems for the
Amplifier Unit, particularly when high resolution is required.
(2) The GND terminal is the 0-V power supply terminal. When using an Amplifier Unit
with an NPN output, the GND terminal is also the common I/O terminal for all I/O
except for the linear output.
(3) The HIGH judgement output outputs judgement results (HIGH).
(4) The PASS judgement output outputs judgement results (PASS).
(5) The LOW judgement output outputs judgement results (LOW).
(6) The linear output outputs a current or voltage in accordance with the measured
value.
(7) The linear output GND terminal is the 0-V terminal for the linear output.
• This ground wire must be grounded separately from the other ground wires.
• Always ground the linear output terminal even when linear output is not used.
(8) If this LD-OFF signal is ON, the laser will stop emission, causing a light amount
error. In this case, the linear output, digital display, judgement output and
judgement output display signals will be output according to the non-measurement
settings.
The sub-display will show [LDOFF].
(9) The zero reset input is used to execute and clear zero reset.
p.118
(10) The timing input is for signal input from external devices. Use it for hold function
timing. The sub-display will show [TIMIG] while the hold function timing is input.
(11) The reset input resets all measurement processing and outputs. The sub-display
will show [RESET] while the hold function reset is input. The linear and judgement
output signals will be output according to the non-measurement settings. If this
reset input switches ON while the hold function is used, the state in effect before
the hold function was set will be restored.
