Meanings of Signal Words

The following signal words are used in this manual.

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.

Meanings of Alert Symbols

The following alert symbols are used in this manual

Indicates general prohibitions for which there is no specific symbol.

Indicates the possibility of laser radiation.

Indicates prohibition when there is a risk of minor injury from electrical

shock or other source if the product is disassembled.

This product is not designed or rated for ensuring safety of persons.

Do not use it for such purposes.

Never look into the laser beam. Doing so continuously will result in

visual impairment.

Do not attempt to dismantle, pressurize, or incinerate the product. Doing

so may cause the laser beam to leak, resulting in the danger of visual

impairment.

ZG User’s Manual

Precautions for Safe Use

The following points are important to ensure safety, so make sure that they are strictly observed.

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.

• Install the product in such a way that its ventilation holes are not blocked.

2.Power Supply and Wiring

• The voltage and AC power supply must be within the rated range (DC 24 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 in the same duct may cause induction, resulting in

malfunction or damage.

• Use the product within the power supply voltage specified by this manual.

• Use a DC power supply with safety measures against high-voltage spikes (safety extra

low-voltage circuits on the secondary side).

3.Other

• Do not disassemble, repair, or modify the product.

• Dispose of this product as industrial waste.

• Connect the exclusive device (Sensor). The product might break down or malfunction

if you use a part not included in the exclusive products.

• Should you notice any abnormalities, immediately stop use, turn OFF the power

supply, and contact your OMRON representative.

ZG User’s Manual

Precautions for Correct Use

Observe the following precautions to prevent failure to operate, malfunctions, or undesirable effects on product performance.

1.Installation Site

Do not install this 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

terminal 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 devices, make sure that the Sensor/Controller is

turned OFF. The Sensor or Controller may break down if it is connected/disconnected

while the power is ON.

• Use the extension cable sold separately for extending the cable between the Sensor

and the Controller.

p.17

• Use only combinations of the Sensor and Controller specified in this manual.

• Before turning the Controller ON, connect the Sensor. If the Controller is turned ON

without the Sensor connected, the Controller’s screen will remain dark and messages

cannot be read.

ZG User’s Manual

3.Warming Up

After turning the power supply ON, allow the product to stand for at least 30 minutes before use. The circuits are still unstable just after the power supply is turned ON, so measurement values may fluctuate gradually.

4.Maintenance and Inspection

Do not use thinner, benzene, acetone or kerosene to clean the Sensor and Controller. If large dust particles adhere to the filter on the front of the Sensor, use a blower brush (used to clean camera lenses) to blow them off. Do not use breath from your mouth to blow the dust off. To remove dust particles from the Sensor, 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 to the filter might cause error.

5.Measurement Target

The measurement target is a non-transparent object. The sensor cannot detect the following types of objects accurately: materials with extremely small reflectances, objects smaller than the beam diameter, objects with large curvatures, or objects tilted to a large degree.

6.Effect of Peripheral Lighting

Do not install the Sensor in a place where strong light hits the laser emitter/receiver section of the Sensor. Also, if a measurement target 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.

Never look into the laser beam. Doing so continuously will result in

visual impairment.

Do not attempt to dismantle, pressurize, or incinerate the product. Doing

so may cause the laser beam to leak, resulting in the danger of visual

Mounting and Connecting Devices

Mounting the ZG-WDS8T

Fix by mounting screws making sure that the distance between the Sensor and measurement target is matched.

Mounting method

Fasten the Sensor onto the mounting base with M4 screws.

Tightening torque: 1.2 N•m

Important

For details on the positions of screw holes, check the external dimensions in “Chapter 5 APPENDICES.”

External dimensions p.164

Mounting position

Mount the Sensor according to the following distances and angle.
