Component Installation and Handling
Precautions for Correct Use
Power Supply and Wiring
To extend the output cables of Amplifier Units, shielded cables of the same
specifications as the output cables must be used.
When using a commercially available switching regulator, make sure that the FG
terminal is grounded.
If surge currents are present in the power lines, connect surge absorbers that suit
the operating environment.
When using two ore more amplifier units, make sure that the linear GND line of the
amplifier units are connected to each other.
Before turning ON the power after the product is connected, make sure that the
power supply voltage is correct, there are no incorrect connections (e.g. load short­circuit) and the load current is appropriate. Incorrect wiring may result in breakdown of the product.
The cables must be 10m or shorter in total length, for both sensor head and amplifier
units. To extend the cable from the sensor head, an optional extension cable (ZX-XCA) must be used. For extension of the cable of amplifier units, shielded cables of the same type must be used.
When using calculation units, make sure that the linear GND lines of the amplifier
units are connected to each other.

Introduction
Precautions for Correct Use
Introduction
Warming Up
After turning ON the power supply, allow the product to stand for at least 10 minutes
before use. The circuits are still unstable just after the power supply is turned ON, so
measured values may fluctuate gradually.
Maintenance and Inspection
Always turn OFF the power supply before adjusting or connecting/disconnecting the
sensor head.
Do not use thinner, benzene, acetone or kerosene to clean the sensor head and
amplifier units. If large dust particles adhere to the front filter of the sensor head, use
a blower brush (used to clean camera lenses) to blow them off. Do not blow the dust
away with your mouth. To remove smaller dust particles, use a soft cloth (for lenses)
with a small amount of alcohol. Take care not to wipe them off with excessive force.
Scratches on the filter may cause errors.
Sensing Object For Reflective Type Sensor Head
The product cannot accurately measure the following types of objects: Transparent
objects, objects with an extremely low reflective sensor ratio, objects smaller than the
spot diameter, objects with a large curvature, excessively inclined objects, etc.
Mutual Interference
Inserting a calculation unit between amplifier units can prevent mutual interference
between two sensor heads. However, this may not work efficiently if one sensor head is
saturated and a laser beam of the other sensor head is input. If you are interested in
installing a calculation unit in order to prevent mutual interference, carry out a test using
the actual system beforehand.

shows the largest reading.
Optical axis adjustment seal
When adjusting the receiver position, take care not to touch the emitter and receiver of the sensor
head. Adhesion of finger marks may hinder correct measurements. If you have touched them,
wipe them with a clean, soft cloth.
The standard received light amount and scaling must be set after completion of optical axis
adjustment.
After optical axis adjustment is complete, remove the optical axis adjustment seal.
Setting the Standard Received Light Amount p.45, Scaling p.67
Installing the Side View Attachment
Fix the side view attachment with M2 screws (supplied with the product). The screws
must be tightened with a torque of 0.08N•m or lower.
The side view attachment can be used even if only the emitter or receiver is mounted.
Make sure that the emitter and receiver are mounted in the correct direction as shown
below. Mounting them in the wrong direction will hinder correct measurements.
Mounting hole

Make sure that the screws are tightened with the same torque. Tightening them with different
torque may cause the optical axis to shift.
Tightening the screws with a torque exceeding 0.08N•m may damage the screw holes. Make sure
that the screws are tightened with the specified torque.
After the side view attachment is mounted, adjust the optical axis.

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.

Setting the Standard Received Light Amount

This function can be used only when the Sensor Head is the Through-beam type.
The current received light amount can be set as the standard received light amount.
The standard received light amount must be set after installation of the sensor head and
adjustment of optical axis. The amount of light input after the standard received light amount is
set will be set to the full scale (F.S.).
Example: When 85% is displayed for the received light amount after completion of optical axis
adjustment
[85.00] is displayed in the main display with the Amplifier Unit set to RUN mode.
Set the standard received light amount.
Section 3 Setting the Standard Received Light Amount
The current light input amount will be set to the full scale, and the main display shows [100.00]. When the standard received light amount is set, [SETST] is displayed in the sub-display.
Setting of the standard received light amount must be carried out while zero reset is not in progress (i.e.
while the zero reset indicator is not lit).
When the standard received light amount is set, the main display and linear outputs (current, voltage) will
be set to the full scale (F.S.) automatically.
Setting of the standard received light amount can be done when the glass on the emitter/receiver gets dirty
or when the received light amount has changed.
If the mount position of the sensor head is changed, the standard received light amount must be set again.

Section 3 Measuring the Received Light Amount (Intensity Mode)
With the intensity mode, all processing, including 2-sensor operation, hold, threshold judgement and linear
outputs, will be performed on the received light amount.
To use intensity mode, intensity mode must be set first. When intensity mode is set, some settings (e.g.

Setting the Measurement Sensitivity (Gain Switching)

This section describes how to set the measurement gain according to the surface condition of the sensing object. Setting the measurement gain to AUTO will automatically adjust the sensitivity to the optimum level for the object. If the amount of reflective sensor light on the object does not change excessively, stable measurements can be carried out by fixing the measurement gain to an appropriate one. Five measurement gains are available: [AUTO] for automatic adjustment, and [BLACK], [WHITE], [METAL] and [MIROR], which are fixed measurement gains. In the case of fixed measurement gains, the measurement sensitivity increases in the order [MIROR], [METAL], [WHITE], [BLACK], [MIROR] with the lowest measurement sensitivity and [BLACK] with the highest measurement sensitivity.

Setting Delay Time
Delay time is set to ignore measurements immediately after the timing input. This is
useful for avoiding bounding during device startup and the influence of machine
vibration.
The delay time (the delay between timing input and the start of sampling) and the
sampling period can be set.
The default delay time setting is [OFF].
Make the sum of the delay time and sampling period less than the timing input ON interval.
If the next timing input for measurement is received before the delay and sampling period have
passed, that timing input will be ignored and will not be reflected in the sampling.

Comparing Measured Values (Differentiation Function)

Use the differentiation function to detect only sudden changes in the measured values that
occur during very short periods of time.
The differentiation function detects changes between the present value and the measured
value that is in effect just before the comparing pitch. The coefficient of this comparing pitch is
defined as the differentiation cycle.
The relationship between the differentiation cycle and comparing pitch can be calculated by
the following equation.
Comparing pitch = Differentiation cycle x 150µs
Example: When differentiation cycle = 10

If you want to detect changes in hold value, use the previous value comparison function.
