Hints on Correct Use

• Do not use this product in saf ety circuits for human pr otection.

• This product is not ex plosion-proof. Do not use the product in 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 noi se.

• When using a commercially a vailable 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 use 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

•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 f or Class 2 output as stipulated by US National Electric Code (NEC) NFPA70.

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

• Connect the FS-N12

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

Installing Sensor Amplifiers

Mounting the Sensor Amplifier

Mounting on a DIN rail

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).

T o release the ampl ifier, raise the amplifier

body in the direction of arrow (3) while pushing in the direction of arrow (1).

Installation on a wall

This method applies only when using the main unit independently. If the main unit is connected with an e xpan sion unit(s), use the method of mounting on a DIN rail.

Mount the amplifier on the amplifier mount-

ing bracket (OP-73880, sold separately), using the same manner as "Mounting on a DIN rail".

Secure the unit with two M3 screws as

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 multiple amplifiers or mounting main units together.

• Turn the power off before connecting multiple expansion units.

• Do not touch the expansion conn ector 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.

Remove the protection covers from the main unit

and expansion unit(s).

Slide the main unit and expansion unit(s) together. Engage the 2 cla ws of the expansion unit with the recesses on the main unit side until you hear/ feel 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) (Tightening torque: 0.6N•m or less).

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.

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

Connecting the Fiber Unit

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.

Installation and Connection

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.

Failure to observe the cautions belo w may resul t in an impr operly 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 stop ping the b lade halfway through.

· Do not use the same hole twice.

Output Switch (L-on/D-on)

This function configures when the output turns ON.

When the current received light inten-

Basic Operation

The current output condition (L-on or Don) is displayed.

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 workpiece 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 dis-

played.

light intensity display is automatically restored.

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:

① 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 absenc e of a workpiece.

② Calibration Sensitivity can be adjusted by a simple operation. This function does not correct t he 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.

Basic Operation

Disabling the preset function

When the PST indicator is lit, press and hold the [PRESET] button.

• The PST indicator turns off, indicating that the preset function has been disabled.

• Once the preset function is disabled, the setting value is recalculated while retaining the ratio of the setting value and received light intensity.

Enabling the work-preset function

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.

Reference

Even if the received light intensity is low during preset and is high during work-preset, the value is set to "100.0" during preset and ".0" during work-

preset. When the actual received light intensity increases, the display will approach ".0". (The preset saturation level is decreased with respect to "100.0".)

Basic Operation

Disabling the work-preset function

When the PST indicator is lit, press and hold the [PRESET] button.
