SENSITIVITY ADJUSTMENT

Place the target object in the desired position for
detection and set the sensitivity adjustment to maximum.

Maximum stability is achieved by varying both horizontal

and vertical alignment of the fiber until it is in the center of
a range in which both the LIGHT (Red) and STABILITY
(Green) indicators illuminate (Light-ON mode).

Remove the object and ensure the LIGHT indicator turns

off and the STABILITY indicator illuminates. If the LIGHT

indicator does not turn off, decrease the sensitivity and

check that there is no other object in line with the fiber.

Ensure the STABILITY indicator illuminates in both

detecting and non-detecting states. (Refer to table below.)

Turn the sensitivity adjustment to maximum.

Position the fiber optic cable ends opposite each other and

adjust the horizontal and vertical alignment until the
STABILITY indicator (Green), LIGHT indicator (Red), and
OUTPUT indicator (Yellow) turn on (Light-ON mode).

Once the desired position is set, introduce the object to the

beam pattern and ensure that the LIGHT and OUTPUT
indicators turn off and the STABILITY indicator illuminates.

If the LIGHT and OUTPUT indicators do not turn off,
decrease the sensitivity until the desired result is achieved.

Ensure that the STABILITY indicator illuminates in both

detecting and non-detecting states. (Refer to table below.)

FIBER CONNECTION AND DISCONNECTION

Uses E32 series fiber-optic cable with grooved tip

(4.75 mm diameter).

Make sure the clamp is raised in the unlocked position.

Firmly insert the fiber-optic cable tips into the amplifier.

Move the clamp down to the locked position (the ridges in
the clamp should slide into the grooves of the tips and

hold the fiber cables in place).

To remove the fiber cables, raise the clamp to the
unlocked position and carefully pull the fiber cables out

of the unit.

E3JU-Xj4j-j

Uses E32 series fiber-optic cable (2.2 mm diameter or

1 mm diameter with E39-F9 adapter).

Make sure the clamp is placed in the unlocked position

Carefully insert the fiber cable into the amplifier, approxi-

mately 14.0 mm (0.55 in).

Caution: The amplifier may be damaged if excessive force is

used when inserting the fiber cables.

Rotate the clamp to the locked position to secure the fiber

cables in place.

To remove the fiber cables, rotate the clamp to the
unlocked position and carefully pull the fiber cables out
of the unit.

Precautions

WARNING

These photoelectric sensors should not be used in personal

safety applications. Using the sensor as a safety device may

cause an unsafe condition that could lead to serious injury or

death.

CAUTION

Cover Screw Torque:

The torque of the cover screw must not exceed 3.5 kgScm

(3 inSlb). Over-torquing twill cause the plastic parts to crack.

HIGH-VOLTAGE LINES

Do not place sensor power supply or signal lines within the same

conduit as high-voltage power lines.

VOLTAGE RATINGS

Do not exceed rated supply voltage, ripple percent (for DC

models), or load current limits.

AMBIENT LIGHTING

Do not install sensor in direct sunlight, or other sources of strong

ambient light.

ENVIRONMENTAL CONDITIONS

Do NOT install sensor in areas with any of these conditions:

High humidity, or where condensation would result.

Corrosive gas.

High vibration or shock.

POWER SUPPLY

If a switching power supply is used, or when using with an
inverter or servomotor, ground the FG (frame ground) and
G (ground) terminals on the power supply for proper operation to

avoid damaging the sensor.

WATER EXPOSURE

Do not use the sensor where it may be immersed, is outdoors, or

exposed to rain.

PROPER MOUNTING SCREWS

Use M5 screws and washers to mount sensor and bracket.

MECHANICAL SHOCK

Avoid mechanical shock during installation which may damage

the housing (see mechanical shock specifications).

CONNECTOR

When connecting or disconnecting the connector, hold the

connector cover to avoid tension on housing.

Tighten connector only by hand. Do not use tools, which may

damage the connector.

Always disconnect power before connecting or disconnecting
the connector.

Be sure that the connector is tightened securely. If this is not

done, the sensor enclosure rating may be reduced, or the
connector may loosen and affect the enclosure rating.
