PRECAUTIONS ON SAFETY

SAFETY PRECAUTIONS FOR USING LASER EQUIPMENT

PRECAUTIONS FOR CORRECT USE

Checking the Package Content

Do not expose your eyes to the laser radiation either directly 
(i.e., after reflection from a mirror or shiny surface). Loss of 
sight may possibly occur in case of the exposure to laser 
high power density.

Do not disassemble the product. Doing so may cause the 
laser beam to leak, resulting in the danger of visual 
impairment.

Indicates a potentially hazardous situation which, if 
not avoided, will result in minor or moderate injury, 
or may result in serious injury or death. Additionally 
there may be significant property damage.

INSTRUCTION SHEET

■ 

Power Supply and Wiring

• 

Do not impose voltage exceeding the rated voltage: 10 to 30 VDC, including 10% ripple (p-p).

• 

When supplying power to the Sensor, make sure that the polarity of the power is correct, and do 

not connect to an AC power supply.

• 

Do not short-circuit the load for the open collector output. Short-circuiting the load may cause 

fire or damage on the Sensor.

• 

Connect the load correctly. Short-circuiting the load may cause fire or damage on the Sensor.

• 

Keep the load within the rated range. Overloading may result in fire or damage on the Sensor.

• 

Wire the product cable separately from high-voltage or power lines. Placing them in the same 

wiring or the same duct may cause induction, resulting in the product malfunction or damage.

• 

Always turn off the power of the Sensor before connecting or disconnecting the cable or 

connector.

• 

Do not use the Sensor for the safety circuits in nuclear power or life-critical applications.

• 

Implement safety measures e.g. fail-safe circuits.

■ 

Installation

• 

Make sure that all installation screws must be tighten securely.

)

■ 

Others

• 

Do not attempt to disassemble, deform by pressure, incinerate, repair, or modify this product.

• 

When disposing of the product, treat as industrial waste.

• 

If you notice an abnormal condition such as a strange odor, extreme heating of the unit, or 

smoke, immediately stop using the product, turn off the power, and consult your dealer.

The ZX1-LD uses a laser as the light source. Lasers are classified based on EN standard (EN 60825-1)

■ 

Installation Location

Do not install the product in locations subjected to the following conditions:

• 

Surrounding air 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, electric arc-welding machines, or 

ultra-violet light)

• 

Direct sunlight or near heaters

• 

Water, oil, or chemical fumes or spray, or mist atmospheres

• 

Strong magnetic or electric field

• 

In the water, rain, or outdoors

■ 

Power Supply and Wiring

• 

Do not supply the power to the Sensor before checking the I/O wiring.

• 

Ground the FG terminal when using a commercially-available switching regulator.

• 

If the power supply line is subject to surges, connect a surge absorber that meets the conditions 

of the operating environment.

• 

Do not turn ON the power after wiring before making sure that the power supply is connected 
correctly; there are no faulty connections, e.g. load short-circuits; the load current is correct. 
Incorrect wiring may result in failure.

• 

Use a ZX0-XC

R Extension Cable (sold separately) to extend the Sensor’s cable. Use only one 

cable. Do not extend the cable for the Sensor to a length exceeding 20 m. 

 The display and indicators turn ON after approx. 2.5 seconds after the power is turned ON.

■ 

Warming Up

 After turning ON the power, allow the Sensor to warm up for approx. 30 minutes prior to use. 

The circuitry is not stable immediately after turning the power ON, and the values gradually 
change until the Sensor is completely warmed up. When using LD-OFF input for a long period 
of time, perform warmng up for more than 30 minutes after cancelling LD-OFF. 

■ 

Maintenance and Inspection

• 

Always turn OFF the power of the Sensor before connecting or disconnecting the cable or for 

making adjustment.

• 

Do not use thinner, alcohol, benzene, acetone, or kerosene to clean the Sensor.

• 

If considerable foreign matter or dust collects on the glass surface of the front of Sensor, use a 
blower brush (for camera lenses) to blow off the foreign matter. Avoid blowing it off with your 
breath. For a small amount of foreign matter or dust, gently wipe with a soft cloth. Do not wipe 
hard. The damaged glass surface may result in detection errors.

■ 

Sensing Object

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.

<Detection Near the Wall Surface>

<Detection of Workpiece with Level Difference>

<Cavity Detection>

Stable detection is possible 
regardless of level difference.

Level difference may cause 
an abnormal detection value.

The Sensor is less 
influenced by ambient 
lighting.

The Sensor is easily influenced by 

ambient lighting, which may cause 

detection value variations. *

Detection is not possible if 
the emitter or receiver section 
is blocked. 

 Caution on Mounting Direction

*

 Before performing tuning, apply mat paint on the wall surface or turn ON the background suppression 

   function to avoid laser light reflection.

Refer to " 5. Background suppression function,

       Detailed Settings"

The following precautions must be observed, since they are essential to ensure safety in operation.

 Installation Environment

 

Do not use the Sensor in locations subject to explosive or flammable gases.

• 

To ensure safety in operation and maintenance, do not install the Sensor near high-voltage 

equipment or power devices.

ON: Laser turns OFF (radiation stop). In this state, analog output, digital 
display, judgment output and judgment output display are output based on 
keep function settings. The digital display shows [          ]. 

Using in a country other than U.S.

For countries other than Japan and U.S., warning labels 

or explanatory labels must be replaced by English ones 
(supplied with the product). EN60825-1 is provided for 
products used in Europe, and the content of this 
standard differs.

The ZX1-LD is categorized as a Class 2 or Class 1  

device as stipulated in EN60825-1:2007.
When using devices in which ZX1-LD is installed 
in the U.S., the devices are subjected to the U.S. 
FDA (Food and Drug Administration) laser 
regulations. ZX1 series is classified into Class2 or 
Class 1 by the standard of IEC/EN60825-1 
according to deviations of Laser Notice NO.50 of 
this standard, and reported to CDRH (Center for 
Devices and Radiological Health).
