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.
The self-diagnosis output is not incorporated with a short-circuit
protection. Do not connect it directly to a power supply or a capacitive
load.
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 a 0.3mm2, 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
explo-sive gases.
Never disassemble or modify the sensor.

How to mount the amplifier
Ԙ
ԙ
Push 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.
Note:
How to remove the amplifier
Ԙ
ԙ
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.
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-receiv-
ing inlet. If they are inserted in reverse, the sensing accuracy will deteriorate.

TIMER FUNCTION
7
٨FX-M1 series incorporate an approx. 40ms fixed OFF-delay timer. Timer
operation is effective when the timer operation selection switch is set to
the 'OFD' side.
Since the output is extended by a fixed period, it is useful when the
connected device has a slow response time or when small objects are
being sensed and the output signal width is small.
Timer period: T = 40ms approx.

INTERFERENCE PREVENTION FUNCTION
8
٨Since the FX-M1 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-D1
series and FX-A1 series.
However, note that the response time varies with the emission
frequency as given below.

observing the operation indicator
(orange). However, since the
lighting up of the operation
indicator depends upon the
combination of the sensing
condition and the selected

MODE, verify it from the table on the right.
The sensitivity adjuster is a 12-turn potentiometer.
The maximum sensitivity is obtained by turning it fully clockwise.
The sensitivity level indicator shows the present
sensitivity level.

In order to protect the mechanism, the sensitivity adjuster idles when over turned, which
may result in a backlash of 1 to 2 divisions.
Depending upon the sensing conditions, stable sensing may be possible at a position
which is slightly shifted from the center point of points and .
Do not move or bend the fiber cable after the sensitivity adjustment.
Detection may become unstable.
Notes: 1)

3)
Set the operation selection
switch to Light-ON mode.
(Initial setting)
Turn the sensitivity adjuster fully
counterclockwise.
(Minimum sensitivity)
Select the mode either Light-ON or Dark-ON according to your application.

In the beam received condition, slowly turn
the adjuster clockwise and find the point
where the sensor is switched ON.
Set the adjuster at the center of points
and . This is regarded as the optimum
sensitivity point.
In the beam not received condition, turn
the adjuster further clockwise until the
sensor goes into the ON state again. Once
it is switched on, turn the adjuster counter-
clockwise a little and find the point
where it is switched OFF.

SELF-DIAGNOSIS FUNCTION
9
٨This is a function which diagnoses a decrease in the incident light
intensity due to dirt or dust, or optical misalignment, and gives an
output.
Ԙ
ԙ
The self-diagnosis output transistor stays in the 'OFF' state during
stable sensing.
When the sensing output changes, if the incident light intensity does
not reach the stable light level or the stable dark level, the self-
diagnosis output becomes 'ON'. It automatically turns 'OFF' after 40ms
approx.
Further, the self-diagnosis output is generated at the time when the
sensing output changes from 'ON' to 'OFF' or from 'OFF' to 'ON'.
(The operation of the sensing output is not affected.)
