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.

* The laser classification for FDA(CDRH) is implemented based on IEC60825-1 in

accordance with the requirements of Laser Notice No.50.

Safety measures for the laser

 Laser radiation emission indicator

The laser radiation emission indicator lights up after turning on the power and

while the laser beam is being emitted.

 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.

The IEC warning/explanatory labels are only included with Class 2 laser

products.

When using this product in the countries and/or regions other than U.S., use the

IEC warning/explanatory label in the package of this product.

In this case, it can be affixed on the FDA (CDRH) warning label, which has

already been affixed to this product.

Check if the parts and equipment listed below are included in the package of the

model you purchased before using the unit.

 Sensor amplifier

 Sensor head

We have thoroughly inspected the package contents before shipment.

However, in the event of defective, broken or missing items, please contact your

nearest KEYENCE office.

Safety Precautions

WARNING

•

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.

•

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.

Safety Precautions on Laser Products

WARNING

•

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

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.

Laser emission stop input 96M11664 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.

Mounting and Wiring the Sensor Amplifier Connecting and Mounting the Sensor Head Mounting the sensor amplifier Sensor head part names Mounting the GV-21/GV-21P (main unit) 1 2 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.

PAGE 4
Configuring the Sensitivity Setting and Operation Mode Using Basic Operations Configure the sensitivity setting in F-1 mode (with the default settings). Detection method 2-point calibration The setting is automatically calculated as the mean value detected from two points: with the workpiece and without the workpiece. 1 The GV Series has two type of detection methods: "Distance detection method" and "Reference surface (DATUM) detection method".
PAGE 5
Configuring the sensitivity setting for distance detection method z Edge hold mode (A-1 mode) This operation mode is suitable for detecting workpieces on a conveyer or detecting workpieces with waving backgrounds. It ignores slow distance changes and only detects workpieces (sudden changes in height).
PAGE 6
Initial reset (initialization) and custom save function 1-point area calibration (operation mode: F-2) 1 2 Press and hold the [SET] button for at least three seconds with the workpiece that you want to detect in place. Release the [SET] button when "SEt" flashes on the display. This concludes 1-point area calibration and the sensor returns to the detection state. Initial reset (initialization) Returns all of the settings to the factory defaults. Set the values for the upper and lower distance.
PAGE 7
Keylock Function DATUM Delay timer 1: Timer value T1 The keylock function prevents accidental operation of the buttons during detection. While using the keylock function, operations other than switching the display for the main screen are prohibited.

1. Response speed setting Display The response speed is the time from when the sensor head starts detection until the value at the detection position is established as a comparator value. Item Response speed Setting range 1.5/3/10/20/50 Setting value Default value (Unit: ms) 10* Time ON OFF ON Off-delay OFF ON One-shot OFF On-delay/ ON Off-delay OFF On-delay/ ON One-shot OFF On-delay * "20" for GV-H1000 (L) only. 2.

9. Setting the shift target value Troubleshooting Set this value to shift the current value by another amount. Item Shift target value Setting range Default value -199 to 999 Problem 0 Press the [Up] and [Down] arrow buttons simultaneously to shift the current value to the set value with the shift target value. The shift status is retained even if the power is turned off. • Reference The current value is larger than the setting value, but the output is not reversed.
