Cautions For Use

Never use this product as a sensing device for personnel protection.
In case of using sensing devices for personnel protection, use products which meet laws and standards, such as OSHA, ANSI or IEC etc., for personnel protection applicable in each region or country.

Part description

[1]Operation indicator (Orange)・・・	Lights up when output is ON.

[2]FX-301-F7：Automatic follow-up function indicator (Green)・・・	Lights up when automatic follow-up function is ON.

FX-301-F：Model indicator (Green)・・・	Lights up during liquid setting (F9 mode).

[3]MODE indicators・・・:	RUN (Green): Lights up during normal sensing operation. TEACH (Yellow): Lights up when the individual teaching mode is selected. ALL (Yellow): Lights up when the collective teaching mode is selected. ADJ (Yellow): Lights up when the threshold value fine adjustment mode is selected or the sensitivity switching function is activated. DISP (Yellow): Lights up when the digital display setting mode is selected or the timer function (FX-301-F only) is activated. OUT (Yellow): Lights up when the forced output mode is selected or the NO / NC switching function is activated.

[3]MODE indicators・・・:

RUN (Green): Lights up during normal sensing operation.
TEACH (Yellow): Lights up when the individual teaching mode is selected.
ALL (Yellow): Lights up when the collective teaching mode is selected.
ADJ (Yellow): Lights up when the threshold value fine adjustment mode is selected or the sensitivity switching function is activated.
DISP (Yellow): Lights up when the digital display setting mode is selected or the timer function (FX-301-F only) is activated.
OUT (Yellow): Lights up when the forced output mode is selected or the NO / NC switching function is activated.

[4]Jog switch・・・	Moving this switch in the “+” or “–” direction, allows different items to be viewed for selection and pressing the switch then confirms the selected setting.

[5]MODE key・・・	This key is used to select operating modes and to cancel settings during the configuration process.

Setting items

Individual teaching mode

When MODE indicator / TEACH (yellow) lights up, threshold value can be set on a single unit.

Timer function (FX-301-F only)

Wiring

Wiring tasks and expansion tasks must be performed with the power off.
Verify that the supply voltage variation is within the rating.
Take care that if a voltage exceeding the rated range is applied, or if an AC power supply is directly connected, the product may get burnt or damaged.
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.
Make sure to use an isolation transformer for the DC power supply. If an autotransformer (single winding transformer) is used, this product or the power supply may get damaged.
When a surge occurs in the power used, absorb the surge with a surge absorber connected to the power source.
Take care that short circuit of the load wrong wiring may burn or damage the product.
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.
Make sure to use the optional quick-connection cable for the connection of the amplifier. Extension up to total 100 m 328.084 ft is possible with 0.3 mm², or more, cable. However, in order to reduce noise, make the wiring as short as possible.

Others

Do not use during the initial transient time (0.5 sec. approx.) after the power supply is switched on.
Take care that the sensor is not directly exposed to fluorescent lamp from a rapid-starter lamp, a high frequency lighting device or sunlight etc., as it may affect the sensing performance.
Do not use this sensor in places having excessive vapor, dust, etc., or where it may come in contact with corrosive gas.
When the fiber head gets dusty or dirty etc. the sensitivity deteriorates. To keep stable detection, wipe the fiber head to remove dust or dirt etc. and carry out sensitivity teaching periodically.
These sensors are only for indoor use.
Take care that the product does not come in contact with oil, grease, organic solvents, such as thinner, etc., strong acid or alkaline.
This sensor cannot be used in an environment containing inflammable or explosive gases.
Never disassemble or modify the sensor.
EEPROM is adopted to this product. It is not possible to conduct teaching 100 thousand times or more, because of the EEPROM's lifetime.
