Precautions for Safe Use
Please observe the following precautions for safe use of the products.
(1) Installation Environment
• Do not use the product in environments where it can be exposed to inflammable/
explosive gas.
• To secure the safety of operation and maintenance, do not install the product close to
high-voltage devices and power devices.
(2) Power Supply and Wiring
• The supply voltage must be within the rated range (DC24 V ± 10 %).
• Reverse connection of the power supply is not allowed.
• Open-collector outputs should not be short-circuited.
• Use the power supply within the rated load.
• High-voltage lines and power lines must be wired separately from this product. Wiring
them together or placing them in the same duct may cause induction, resulting in mal-
function or damage.
(3) Regulations and Standards
• EN61326-1
• Electromagnetic environment : Industrial electromagnetic environment (EN/IEC 61326-
1 Table 2)
• The following condition is applied to the immunity test of this product: There may be
cases that current or voltage output fluctuate within ±3%F.S. when a sensor is experi-
enced electromagnetic interference.
• Notice for Korea Radio Law

Introduction
Precautions for Correct Use
Please observe the following precautions to prevent failure to operate, malfunctions, or
undesirable effects on product performance.
(1) Installation Site
Do not install the product in locations subjected to the following conditions:
• Ambient temperature outside the rating
• Rapid temperature fluctuations (causing condensation)
• Relative humidity outside the range of 35 to 85 %
• Presence of corrosive or flammable gases
• Presence of dust, salt, or iron particles
• Direct vibration or shock
• Reflection of intense light (such as other laser beams or electric arc-welding
machines)
• Direct sunlight or near heaters
• Water, oil, or chemical fumes or spray
• Strong magnetic or electric field
(2) Power Supply and Wiring
• When using a commercially available switching regulator, make sure that the FG ter-
minal is grounded.
• If surge currents are present in the power lines, connect surge absorbers that suit the
operating environment.
• 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 short-circuit)
and the load current is appropriate. Incorrect wiring may result in breakdown of the
product.
• Before connecting/disconnecting the Sensor Head, make sure that the Smart Sensor
is turned OFF. The Smart Sensor may break down if the Sensor Head is connected or
disconnected while the power is ON.
• Use the Extension Cable (provided) for extending the cable between the Sensor Head
and Sensor Controller. The total length varies according to the type of Extension Cable.
- Extension Cable: ZS-XC_A: within 10 m (including Sensor Head cable. Extension
Cable cannot be daisy-chained.)
- Extension Cable: ZS-XC_B(R): within 22 m (including Sensor Head. Up to two
Extension Cables can be daisy-chained.)
- Extension cable for a long distance ZS-XC_ _CR: within 27 m (including Sensor
Head. Digital equalizer ZS-XEQ and the Digital equalizer connection cable ZS-
XC02D are necessary. The extension cable cannot be daisy-chained.)
• The cable may break at locations when it is made to bend. So, use the robot cable
type Extension Cable (ZS-XC5BR, ZS-XC_ _CR).
• Use only combinations of Sensor Heads and Sensor Controllers specified in this man-
ual.

Precautions for Correct Use
(3) Orientation when Installing the Sensor Controller
(4) Warming Up
After turning ON the power supply, allow the product to stand for at least 30 minutes
before use. The circuits are still unstable immediately after the power supply is turned
ON, so measured values may fluctuate gradually.
(5) Maintenance and Inspection
Do not use thinner, benzene, acetone or kerosene to clean the Sensor Head and Sen-
sor Controller. 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 par-
ticles with your mouth. To remove smaller dust particles, wipe gently with a soft cloth
(for cleaning lenses) moistened with a small amount of alcohol. Do not use excessive
force to wipe off dust particles. Scratches on the filter may cause errors.
(6) Sensing Objects
The product sometimes cannot accurately measure the following types of objects:
Transparent objects, objects with an extremely low reflection factor, objects smaller
than the spot diameter, objects with a large curvature, excessively inclined objects, etc.
(7) Effect caused by peripheral lights
Do not install the Sensor Head in a place where strong light hits the laser emitter/
receiver section of the Sensor Head. Also, if a workpiece has a shiny surface, the light
from the lighting will be reflected and a malfunction may occur. In such a case, prevent
reflection by, for example, covering the light to stop reflection.
p.2-4
To improve heat radiation, install the Sensor Controller only in
the orientation shown below.
Do not install the Sensor Controller in the following orientations.

Setting the Filter Function
Set the conditions for filtering information obtained from the sensor.
Setting SMOOTH
The intermediate value of multiple sets of data can be output as the measurement result.
This function removes any abnormal values such as spiking that occur when the shape of
the workpiece suddenly changes during measurement.
Example: To remove spiking
FUN Mode-[FILTER]-[SMOOTH]
When "HI-SPEED" is set in the measurement mode, [OFF] is set.
