Make sure to carry out the wiring in the power supply off condition.
Verify that the supply voltage variation is within the rating.
In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity
of this product, connect the frame ground (F.G.) terminal of the equipment to an actual ground.
If power is supplied from a commercial switching regulator, ensure that the frame
ground (F.G.) terminal of the power supply is connected to an actual ground.
Do not use during the initial transient time (0.5 sec.) after the power supply is switched on.
Do not run the wires together with high-voltage lines or power lines or put them in
the same raceway. This can cause malfunction due to induction.
Extension up to total 100m is possible with 0.3mm

, or more, cable. However, in
order to reduce noise, make the wiring as short as possible.
This sensor is suitable for indoor use only.
Avoid dust, dirt, and steam.
Take care that the product does not come in direct contact with organic solvents,
such as, thinner, etc.
This sensor cannot be used in an environment containing inflammable or explosive gases.
Never disassemble or modify the sensor.

Please refer to ' SETTING OF THRESHOLD

value, ' SETTING OF EACH MODE' for the
output selection and the method of setting the
output operation and the timer.

Since the FX-D1 series incorporate two independent outputs, threshold value,
output operation and timer can be set for each of the two outputs.

SETTING OF THRESHOLD VALUE

8

٨٨When the mode selection switch is changed from 'SET' to 'RUN' or from

'MODE' to 'RUN', the set threshold value or the contents of each mode
setting are stored in an EEPROM. Since the EEPROM has a life time,
the threshold value setting cannot be done for more than 100,000 times.
Do not move or bend the fiber cable after the sensitivity setting. Detection may become unstable.

٨

This is the method of setting the threshold value by teaching two levels, corresponding to
the object present and object absent conditions. Normally, setting is done as given below.

In case of 2-level teaching

If the jog switch is pressed continuously for 3 sec., or more, full auto-teaching is done.
If the mode selection switch is changed to 'RUN' when '˴˴' is being displayed on the
LCD display, the incident light intensity taught at Step Ԝ is not recorded.

Notes: 1)

Ԡ

࡮࡮Set the mode selection switch to 'RUN'.

The threshold value does not change even if the jog switch is operated.

ԟ

࡮࡮If teaching is accepted, the read incident light intensity is displayed for 0.5 sec. approx., and the threshold

value is set to the middle value of the incident light intensity levels in the object present and object absent
conditions. After that, the judgement on the stability of sensing is displayed for 2.5 sec. approx.

After this, the threshold value is displayed.

In case stable sensing is not possible: ' ' is displayed.

ԘԙFit the rear part of the mounting section of the amplifier on the attached

amplifier mounting bracket (MS-DIN-2) or a 35mm width DIN rail.
Press down the rear part of the mounting section of the unit on the
attached amplifier mounting bracket (MS-DIN-2) or a 35mm width
DIN rail and fit the front part of the mounting section to the attached
amplifier mounting bracket (MS-DIN-2) or a 35mm width DIN rail.

How to mount the amplifier

Ԛ

Snap the fiber lock lever down.
Insert the fiber cables slowly into the inlets until they stop. (Note 1)
Return the fiber lock lever to the original position, till it stops.

Fiber

Beam-emitting part

Beam-receiving part

Notes: 1)2)In case the fiber cables are not inserted to a position where they stop, the sensing range reduces.

However, in case of a flexible fiber, take care that it may bend inside the amplifier, during insertion.
With the coaxial reflective type fiber, such as, FD-G4 or FD-FM2, insert the single-core
fiber cable into the beam-emitting inlet and the multi-core fiber cable into the beam-receiv­ing inlet. If they are inserted in reverse, the sensing accuracy will deteriorate.

How to connect the fiber cables

ԘԙPush the amplifier forward.

Lift up the front part of the amplifier to remove it.

Ԙ

ԙ

Take care that if the front part is lifted without pushing the amplifier forward,
the hook on the rear portion of the mounting section is likely to break.

٨ FX-D1 series incorporate an ON-delay timer, which is useful when sensing only

objects with a long passage time, and an OFF-delay timer, which is useful when
the sensor is connected to devices having a slow response time. The timer period
can be selected from four values: 40ms, 100ms, 200ms and 500ms.
Please refer to ' SETTING OF EACH MODE' for the setting method.

٨ Since the FX-D1 series incorporate an interference prevention function, up to 3

sets of fibers can be mounted close to each other by setting different emission
frequencies. Further, close mounting is also possible along with fibers which are
fitted to the fiber sensor amplifiers, FX-A1 series and FX-M1 series.
Please refer to ' SETTING OF EACH MODE' for the setting method.

٨ This is the method of setting the threshold value by teaching only the object absent

condition (incident light stable condition). This is used for detection in presence of a
background body or for detection of small objects.

If the jog switch is pressed continuously for 3 sec., or more, full auto-teaching is done.

After setting the threshold value, the current incident
light intensity can be expressed as a percentage of the
threshold value so that the degree of margin can be
confirmed at a glance. If the jog switch is pressed when
the mode selection switch is set on 'RUN', the display
changes from absolute value to percentage value, and
0 to 999% is displayed. However, % (percent) is
expressed by ' ' and fractions are rounded off.
If the jog switch is pressed once again, the
display returns to absolute value.
Further, in case percentage display is desired
when the power supply is switched off, and then,
on again, change the mode selection switch once
to 'SET' or 'MODE', and then, set it back to 'RUN'.
