Safety Precautions

Refer to Warranty and Limitations of Liability.

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 in atmospheres or environments that exceed

product ratings.

● Designing

Power Supply

A power supply with full-wave rectification can be connected to the

E3G-MR19(T).

● Wiring

The tensile strength of the cable during operation should not exceed

the values shown below.

● Adjusting

Indicators

• The following illustration indicates the operating levels of the E3G.

• Set the E3G so that it will work within the stable operation range.

● Designing

Power Supply

A power supply with full-wave rectification can be connected to the

E3G-ML79(T).

● Wiring

The tensile strength of the cable during operation should not exceed

the values shown below.

● Mounting

Mounting

• If there is a mirror-like object below the Sensor, the Sensor may not

be in stable operation. Therefore, incline the Sensor or keep the

Sensor a distance away from the mirror-like object as shown below.

• Make sure not to install the Sensor in the incorrect direction. Refer

to the following.

Install the Sensor as shown in the following if each sensing object

greatly differs in color or material.

● Others

EEPROM Write Errors

If a teaching data error occurs with the operation indicator flashing

due to a power failure or static noise, perform the teaching operation

of the Sensor again.

*If the operating level is set to the stable operation range, the E3G will operate with the

highest reliability and without being influenced by temperature change, voltage fluctuation,

dust, or setting change. If the operating level cannot be set to the stable operation range,

pay close attention to environmental changes while operating the E3G.

Mounting Directions

• Make sure that the sensing side of the

Sensor is parallel with the surface of

each sensing object. Do not incline the

Sensor towards the sensing object.

If the sensing object has a glossy

surface, incline the Sensor by 5

° to 10°

as shown below, provided that the

Sensor is not influenced by any

background objects.
