Instruction Manual

Read this manual before using the software in order to achieve maximum
performance.
Keep this manual in a safe place after reading it so that it can be used at any time.

The displayed values indicate guidelines for distances and should not
be used in the actual applications for measurement.

Safety Precautions

•

This product is only intended to detect object(s). Do not use this
product for the purpose to protect a human body or part of a
human body.

•

WARNING

Safety Precautions on Laser Products

This product is not intended for use as an explosion-proof
product. Do not use this product in a hazardous location and/or
potentially explosive atmosphere.

 Laser emission stop input

The laser emission stops when an emission stop (purple line) signal is input (for
20 ms or longer). The emission stops while the signal is input. The laser beam is
emitted a maximum of 20 ms after the signal input is canceled. The control
output functions according to the detection value even while laser emission
stop is input.

 Laser warning labels

The following diagrams show the type and position of laser warning labels
according to the GV Series.

•

This product employs a semiconductor laser for its light source.

•

Use of controls or adjustments or performance of procedures other
than those specified herein may result in hazardous radiation
exposure.

•

Follow the instructions mentioned in this manual. Otherwise, injury
to the human body (eyes and skin) may result.

•

Do not disassemble this product. Laser emission from this product
is not automatically stopped when it is disassembled.

Precautions on class /2 laser products

• Do not stare into the beam.

• Do not direct the beam at other people or into areas

WARNING

where other people unconnected with the laser work
might be present.

• Be careful of the path of the laser beam.

If there is a danger that the operator may be exposed
to the laser beam reflected by specular or diffuse
reflection, block the beam by installing an enclosure
with the appropriate reflectance.

• Install the products so that the path of the laser beam

is not as the same height as that of human eye.

Precaution on class 1 laser products

• Do not stare into the beam.

Mounting the sensor amplifier

 Mounting the GV-21/GV-21P (main unit)

1 Align the claw at the bottom of the

main body with the DIN rail. While
pushing the main body in the
direction of the arrow 1, slant it in the
direction of the arrow 2.

2 To dismount the sensor, raise the

main body in the direction of the
arrow 3 while pushing the main body
in the direction of the arrow 1.

When using the amplifier mounting bracket
(OP-76877) (sold separately), mount it as
shown in the diagram to the right.

 Mounting the GV-22/GV-22P (expansion unit)

Several expansion units can be used in connection with the main unit.
Up to three expansion units can be connected to one main unit.

•

When connecting multiple amplifiers (expansion units),
first check to make sure that the power is turned off to all
of the main and expansion units. Connecting the units
with the power turned on may cause damage to the units.

•

Push the amplifiers (expansion units) as far as possible into

CAUTION

Expansion units with different output types (such as a PNP output main
unit to an NPN output expansion unit) cannot be connected together.

the main unit. If they are connected at a slant or not inserted
securely, the units may be damaged.

•

Only GV Series amplifier can be connected (DL Series
cannot be connected). Connecting other amplifiers may
cause damage to the units.

Connecting and Mounting the Sensor Head

Sensor head part names

Connecting the sensor head

1 Unlock the sensor head

connector and insert it into
back of the amplifier.

2

Turn the round part of the
connector clockwise until a
clicking sound is heard to lock
it.

When shortening the sensor head cable, follow the instructions given in
the "Sensor Head Connector Assembly Manual" included with the sensor
head.

1 Remove the expansion

protective cover from the
GV-21/GV-21P (main unit)

2 Install the amplifiers (expansion units) on the DIN rail.

For more information about mounting, see "Mounting the GV-21/GV-21P (main
unit)".

3 Push the expansion unit into

the main unit connector until
a clicking sound can be
heard.

4

Install the end units
(OP-26751: 2 units in a set)
(sold separately) on either
side of the amplifiers (main or
expansion units). Secure the
end units in place with screws
on top (2 on each end unit).

The end units are mounted in the same way as the amplifiers.

Amplifier wiring

The following information shows the I/O cable.
For more information about the I/O circuit, see page 9 of this Instruction Manual.

GV-IM-E

GV-22/GV-22P (expansion unit) do not
have brown or blue lines. Power is supplied
to the expansion units through GV-21/GV­21P (main unit).

*2 The external input switches as shown

below depending on the amplifier
OPTIONAL settings.

• oFF ......... Input off

• SFt .......... External shift

• bnK ......... Bank switching

• tim........... Timing input

Mounting the sensor head

Use the dedicated mounting bracket to mount the sensor head.
When not using the dedicated mounting bracket, the included insulating sheet must be
inserted between the mounting surface and the sensor head as shown in the diagram.
(When using the dedicated mounting bracket, the insulating sheet is not necessary.)

of this Instruction Manual.
The spot reflection indicator lights up during normal detection and turns off

When using sensor head GV-H130

For example, when using the defaults with the setting value (green) at 500, the
comparator output turns on when the current value is 500 or greater and turns off
when it is less than 500.
If multiple reflection (when multiple peaks of received light intensity occurs due to
diffuse reflection) occurs during F-1, F-2, or A-1 modes, the value immediately

When the channel No. 1 indicator is lit, the control output 1 (black line)
setting value is displayed. When the channel No. 2 indicator is lit, the
control output 2 (white line) setting value is displayed.
Operations are different in F-2 mode. (See page 5 of this Instruction
Manual.)

z Current value and display resolution

In the default state, the current value shows 0 when the workpiece is located at
the maximum detection distance. Bringing the workpiece closer to the sensor
head gradually increases the value and displays it up to the minimum detection
distance.
