E3X-HD

Safety Precautions

Refer to the Fiber Sensors Technical Guide for precautions that apply to all Fiber Sensors.

• Be sure to mount the unit to the DIN track until it clicks.

• Use an extension cable with a minimum thickness of 0.3 mm2 and

less than 100 m long.

• Do not subject the cable to more than the following forces.

Pull: 40 N; torque: 0.1 N

⋅m; pressure: 20 N; bending: 29.4 N

• The Sensor is ready to operate 200 ms after the power supply is

turned ON.

• When using Amplifier Units with Wire-saving Connectors, attach

the protective stickers (provided with E3X-CN-series Connectors)

on the unused power pins to prevent electrical shock and short

circuiting.

When using Amplifier Units with Connectors for Communications

Units, attach the protective caps (provided with E3X-CRT/ECT

Sensor Communications Unit).

• Output pulses may occur when the power supply is turned OFF. Turn

OFF the power supply to the load or load line first.

• Excessive incident light cannot be sufficiently handled by the

mutual interference prevention function and may cause

malfunction. To prevent this, set a higher threshold level.

• Make sure that the power supply is turned OFF before connecting,

separating, or adding Amplifier Units.

• Do not pull on or apply excessive pressure or force to the Fiber Unit

when it is attached to the Amplifier Unit.

• The E3X-MC11, E3X-MC11-SV2 and E3X-MC11-S Mobile

Consoles cannot be used.

• Mutual interference prevention on the E3X-HD Series does not

function among the E3NX-FA, E3X-DA-N, E3X-SD, or E3X-NA

Fiber Amplifier Units.

Mutual interference prevention on the E3X-HD Series does

function among the E3X-DA-S and E3X-MDA Fiber Amplifier Units.

• The E3X-CRT and E3X-ECT Sensor Communications Unit can be

used with the E3X-HD0, but the E3X-DRT21-S and E3NW-ECT

Sensor Communications Units cannot be used.

• Always keep the protective cover in place when using the Amplifier

Unit.

• Do not use thinner, benzine, acetone, and kerosene for cleaning.

Technical Guide on your OMRON website.

Warning

This product is not designed or rated for ensuring

safety of persons either directly or indirectly.

Do not use it for such purposes.

Do not use the product with voltage in excess of the

rated voltage.

Excess voltage may result in malfunction or fire.

Never use the product with AC power supply.

Otherwise, explosion may result.

Precautions for Safe Use

The following precautions must be observed to ensure safe

operation of the product. Doing so may cause damage or fire.

1.

Do not install the product in the following locations.

• Locations subject to direct sunlight

• Locations subject to condensation due to high humidity

• Locations subject to corrosive gas

• Locations subject to vibration or mechanical shocks

exceeding the rated values

• Locations subject to exposure to water, oil, chemicals

• Locations subject to stream

• Locations subjected to strong magnetic field or electric field

2.

Do not use the product in environments subject to flammable

or explosive gases.

3.

To secure the safety of operation and maintenance, do not

install the product close to high-voltage devices and power

devices.

4.

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 malfunction or

damage.

5.

Do not apply load exceeding the ratings. Otherwise, damage or

fire may result.

6.

Do not short the load. Otherwise, damage or fire may result.

7.

Connect the load correctly.

8.

Do not miswire such as the polarity of the power supply.

9.

Do not use the product if the case is damaged.

10. Burn injury may occur. The product surface temperature rises

depending on application conditions, such as the ambient

temperature and the power supply voltage. Attention must be

paid during operation or cleaning.

11. When setting the Sensor, be sure to check safety, such as by

stopping the equipment.

12. Be sure to turn off the power supply before connecting or

disconnecting wires.

13. Do not attempt to disassemble, repair, or modify the product

Unit in any way.

14. When disposing of the product, treat it as industrial waste.

15. Do not use the Sensor in water, rainfall, or outdoors.
