Safety Precautions

Hints on Correct Use

•Do not use this product in safety circuits for human protection.

•This product is not explosion-proof. Do not use the product in

WARNING places with flammable gas, liquid, or dust.

•This product uses DC power. Do not apply AC power. The product may explode or burn if an AC voltage is applied.

•Do not wire the amplifier line along with power lines or high-tension 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.

•Do not use the FS 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 fiber unit models, the maximum sensing distance or displayed value may not be the same on all units.

•If the sensor is used for a long time with the APC function enabled and the LED is imposed with a heavy load, the current consumption of the sensor for light emission will become constant and 'END APC' will be displayed. The sensor can still be used in this case. However, replace the sensor if even small changes in received light intensity should be detected for precise detection.

About UL Certification

The FS-N Series is UL and C-UL certified, and is compliant with the UL and CSA standards.

• Applicable standardsUL508 Industrial Control Equipment

CAN/CSA C22.2 No.14-M05 Industrial Control Equipment

•UL File No. E301717

•UL categories: NRKH, NRKH7

•Enclosure Type 1 (based on UL50 standard)

Notes on UL Certification

•The power source used with the FS-N Series must be UL Listing certified for Class 2 output as stipulated by US National Electric Code (NEC) NFPA70.

•Power supply/Control input/Control output shall be connected to a single Class 2 source only.

•Connect the FS-N12 and N14 to the FS-N11 and N13 main units for use.

•Use with the over current protection device which is rated 30V or more and not more than 1A.

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 direc-
	tion 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

pushing in the direction of arrow (1).

(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
	shown in the illustration.	OP-73880

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 Fiber Sensor FS-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 FS-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 FS-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 FS-N10 Series.

1	Remove the protection covers from the main unit Main unit	Expansion unit
	and expansion unit(s).
2	Mount the main unit and expansion unit(s) on the
	(3)
	DIN rail.

(2)

(1)

3	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 a click.
4	Attach the separately sold end units (OP-26751: a
	set of 2 units) to the DIN rail in the same manner
	as step (2) (Tightening torque: 0.6N•m or less).
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 Fiber Unit

This section provides procedures for connecting the fiber unit and operating precautions.

1 Install the fiber unit.

After the installation, check that the transmitter and receiver of the sensor are spaced properly. Also check that the optical axis is aligned.

2 If the fiber unit is a free cut type, cut any excess length of the fiber.

(1)Insert the fiber into the hole in the cutter.

(2)Bring down the blade in a single, swift motion to cut the fiber.

	(2)
Fiber	Fiber cutter
	(OP-87098)

Always insert fiber from the side with writing.

Point Failure to observe the cautions below may result in an improperly cut surface, which may reduce the detection distance.

·When cutting the fiber unit, be sure to use a gray fiber cutter (OP-87098)

·Cut the fiber unit in a single motion without stopping the blade halfway through.

·Do not use the same hole twice.

3	Open the dust cover in the
	direction of arrow (1).

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

3-3 Adjusting Sensitivity

This manual refers to the values that select ON/OFF output of the sensor amplifiers as "Set values." In addition, the manual refers to the adjustment of set values as "Adjusting Sensitivity." This section describes the sensitivity adjusting method.

List of Sensitivity Adjusting Methods

Sensitivity adjusting method for the FS-N10 Series is broadly divided into two categories:

Preset

Simple operation allows sensitivity adjustment concurrently with correction of the received light intensity to "100.0" or "0.0"

This function helps preventive maintenance by eliminating dispersion of the received light intensity due to the contents of detection or individual workpieces.

However, this is not suitable for detection of transparent workpiece because there is a small difference in the received light intensity between presence and absence of a workpiece.

Calibration

Sensitivity can be adjusted by a simple operation. This function does not correct the received light intensity.

This function is applied for using the received light intensity without correction or for high-precision detection.

Calibration is also available in a preset state.

Work-Preset Function

This function calibrates the current value to ".0". After the preset function has been executed with "100.0" displayed, and then executing this function with ".0" displayed, 2 random set points can be calibrated to "100.0" and ".0".

* Not available for the FS-N10 Series shipped before March 10, 2011.

Enabling the work-preset function

Impotant The work-preset function can be used with the preset function (when preset is enabled).

While the preset function is enabled, press the [PRESET] button and button simultaneously.

The received light intensity

at that point is set to ".0". The value set to "100.0" using

the preset function does not change.
