Safety Precautions

General Precautions

				•	This product is only intended to detect objects. Do not use this
					product for the purpose of protecting a human body or a part of
					the human body.
				• This product is not intended for use as an explosion-proof prod-
	WARNING				uct. Do not use this product in a hazardous location and/or
					potentially explosive atmosphere.
				•	This product uses DC power. Do not apply AC power. The prod-
					uct may explode or burn if an AC voltage is applied.
				• Do not wire the amplifier line along with power lines or high-ten-
					sion lines, as the sensor may malfunction or be damaged due to
					noise.
				• When using a commercially available switching regulator,
					ground the frame ground terminal and ground terminal.
	NOTICE			•	Do not use the LV-N10 Series outdoors, or in a place where
					extraneous light can enter the light-receiving element directly.
				•	Due to individual dispersion characteristics and the difference
					in sensor head models, the maximum sensing distance or dis-
					played value may not be the same on all units.

Safety Precautions on Laser Product

	• This product uses a semiconductor laser for the light source.
	•	Use of controls or adjustments or performance or procedures
		other than those specified herein may result in hazardous radia-
		tion exposure.
	•	Follow the instructions mentioned in this manual. Otherwise,
WARNING		injury to the human body (eyes and skin) may result.
	Precautions on Class 1 laser products

•Do not stare into the beam.

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

Safety Precautions

*The laser classification for FDA (CDRH) is implemented based on IEC60825-1 in accordance with the requirements of Laser Notice No.50.

Reference Laser Transmission OFF input

When the laser transmission OFF input is set for external input, the laser transmission can be stopped by turning the external input ON (2 ms or longer). The transmission is stopped while the external input is ON. Once the external input is turned OFF, the laser transmission will resume within 20 ms.

Connection and Installation

2-1 Installing Sensor Amplifiers

Mounting the Sensor Amplifier

Mounting on a DIN rail

1	Align the claw at the bottom of the main body
	with the DIN rail, as shown on the right.
	While pushing the main body in the direction
	of the arrow (1), push down in the direction of
	arrow (2).
2	To release the amplifier, raise the amplifier
	body in the direction of arrow (3) while push-

ing in the direction of arrow (1).

(3)

(2)

(1)

Installation on a wall

Reference This method applies only when using the main unit independently. If the main unit is connected with an expansion unit(s), use the method of mount-

	ing on a DIN rail.
1	Mount the amplifier on the amplifier mount-
	ing bracket (OP-73880, sold separately),
	using the same manner as "Mounting on a
	DIN rail".
2	Secure the unit with two M3 screws as	OP-73880
	shown in the illustration.

Connecting multiple amplifiers

Up to 16 expansion units can be connected to 1 main unit. Note, however, that the 2- output type is considered as 2 expansion units.

Mount on DIN rail and install on metal surface when connecting WARNING multiple amplifiers or mounting main units together.

2-2	- Digital Laser Sensor LV-N10 Series User's Manual -

2-1 Installing Sensor Amplifiers

Point • Contact your nearest KEYENCE office when connecting a unit other than the N-bus (KEYENCE’s wire-saving system) compatible sensor amplifier, including LV-N10 Series, or the NU Series communication module.

• Turn the power off before connecting multiple expansion units.

•Do not touch the expansion connector with your bare hands.

•When using the LV-N10 Series as a main unit, use the products within the expansion unit’s power voltage range if the power voltage range of the expansion unit is narrower than the LV-N10 Series.

1	Remove the protection covers from the main unit
	and expansion unit(s).
2	Mount the main unit and expansion unit(s) on the
	DIN rail.
	(2)
3	(1)
	Slide the main unit and expansion unit(s) together.
	Engage the 2 claws of the expansion unit with the
	recesses on the main unit side until you hear/ feel
4	a click.
	Attach the separately sold end units (OP-26751: a
	set of 2 units) to the DIN rail in the same manner
	as step (2).
5	Secure the amplifiers between the end units.
	Tighten the screws at the top (2 screws × 2 units)

with a Phillips screwdriver to fix the end units.

2-2 Connecting the Sensor Amplifier to the Sensor Head

Connecting the Sensor Amplifier to the Connector

1	Open the dust cover, and move the hold
	lock lever down.
2	Lift the hook up, and insert the connec-
	tor completely.
3	Lower the hook to the position
	shown in the drawing, and pull
	up the hold lock lever.

Point		• When connecting to a different sensor head model, the settings for
		the previously connected model will be saved.
		Either reconfirm or initialize the settings.

"Initialization of Settings (Reset to Initial Values)" (page 3-21)

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

3-2 Switching Output

Output Switch (L-on/D-on)

This function configures when the output turns ON.

1	When the current received light inten-
	sity is displayed, press the [MODE] but-
	ton.
	The current output condition (L-on or D-
	on) is displayed.*1
2	Press the	button to switch the out-
	put condition, and then press the

[MODE] button.

Select "D-on" if you want to output the ON signal when the beam is blocked (a work-

piece is present.) for a thrubeam or retro-reflective model.

Select "L-on" if you want to output the ON signal when the beam is received (a workpiece is present.) for the reflective model.

The output condition is switched, and the current received light intensity is displayed.*2

*1 If you do nothing for 3 seconds or more or press the [MODE] button, the received light intensity display is automatically restored.

*2 When using the sub-display, the screen will switch between the current received light intensity J L-on/D-on screen J sub-display J current received light intensity and so forth each time the [MODE] button is pressed.

Point • When in area detection mode, rising edge detection mode, falling edge detection mode, counter output mode, or when the LV-S31 is connected, this function works as a normally-open/normally- closed switch.

3-3 Adjusting the Sensitivity

In this manual, the value at which the sensor amplifier's ON/OFF output switches is expressed as the "setting value". The process of adjusting the setting value is expressed as "adjusting the sensitivity". This section explains the method of adjusting the sensitivity.

List of Sensitivity Adjustment Methods

The methods of adjusting the LV-N10 series sensitivity is largely classified into 2 types.

(1) Preset

At the same time as adjusting the sensitivity, the received light intensity can be calibrated to "100.0" or ".0" using simple operations.

This method can decrease the variation of the received light intensity depending on the contents of the detection and the workpiece, and is useful for predictive maintenance.

However, this is not suitable for when difference in received light intensity varies little with or without a workpiece, such as when detecting a transparent workpiece.

(2) Calibration

The sensitivity can be adjusted with simple operations. The received light intensity is not compensated.

This method is used to adjust without calibrating the received light intensity, or when highly accurate detection is required.

Calibration can be performed in the preset state.
