Connecting Multiple Amplifiers

Up to 16 expansion units can be connected to one main unit. However, two output types will be

treated as two main units.

1 Remove the protection covers from the main unit

and expansion unit(s).

2 Install the amplifiers on the DIN rail one at a time.

3 Slide the main unit and expansion unit(s) together.

Engage the two claws of the expansion unit with

the recesses on the main unit side until you hear/

feel a click.

4 Attach the end units (option: OP-26751) to the DIN

rail in the same way as step (2).

5 Secure the amplifiers between the end units.

Tighten the screws at the top (two screws x two

units) with a Phillips screwdriver to fix the end

units.

Calibration Method



Detecting Even Small Differences

Two-point Calibration

Two-point calibration is the basic method of calibration.

Press the [SET] button once without the workpiece, and then press it once again with the

workpiece.

1 Press the [SET] button with no workpiece.

[SET] will be displayed on the sub-menu (green display).

2 Press the [SET] button with workpiece.

The values will be set and the submenu (green display) will flash. The values will be set to

the mid-point between the light intensity when there is no workpiece, and the light intensity

when there is a workpiece.

If "----" flashes for two seconds on the main screen, the light intensity is too small between

conditions when the workpiece is absent and when it is present. These values will be set,

but there is the possibility that detection may become unstable.

Other Calibration Methods



Increased Resistance to Dust and Dirt

Maximum Sensitivity Calibration

In the state shown below, press and hold the [SET] button for three seconds or more. Stop

pushing when "5'6" flashes.

The sensitivity is set slightly higher than the received light intensity.



Calibrate with a Moving Workpiece

Fully Automatic Calibration

Press and hold the [SET] button with no workpiece in place. While “5'6” is flashing, pass a

workpiece through. (Continue pressing the [SET] button while the workpiece passes through.)



Position Workpiece

Positioning Calibration

Press the [SET] button with no workpiece.

Place the workpiece in the location you wish to position it. Press and hold the [SET] button

for at least 3 seconds. Release the button when "5'6" flashes.

Simple, User Friendly Functions



Setting the Current Value to 100.0

With the FS-N10 Series, you can set the current value to 100.0 using simple operations.

Standardizing the current value makes it possible for the sensor amplifiers to instantly differ-

entiate reductions in light intensity and is useful in predicting the need for maintenance.

• If a thin fiber unit is used, an adapter provided with the thin fiber unit will be

required.

Unless the correct adapter is connected, the thin fiber unit will be loose and

not detect targets correctly (the adapter is supplied with the fiber unit).

• To connect the coaxial reflective type fiber unit to the amplifier, connect the

single-core fiber to the transmitter side, and connect the multiple-core fiber

to the receiver side.

Mount on DIN rail and install on metal surface when connecting to

multiple amplifiers or mounting main units together.

• When connecting with units other than N-bus (a general term for the KEY-

ENCE wire-saving connection system) compatible sensor amplifiers,

including the FS-N10 Series, and the network unit NU Series, consult your

nearest KEYENCE dealer.

• Turn the power off before connecting multiple expansion units.

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

Workpiece

• The various Preset functions listed below cannot be used when the Zero-

Shift function is enabled. Disable the Zero-Shift function before executing

the following functions.

• The Preset functions are not suited for transparent workpieces and other

cases of detection with low light intensity differences.

You can disable various Preset functions by pressing and holding the [PRESET]

button.
