SENSITIVITY SETTING
7
٨
٨
٨
When the mode selection switch is set to 'SET' or 'MODE', the sensor is
more susceptible to extraneous light. Hence, when sensing objects, ensure to set
the mode selection switch to 'RUN'.
When the mode selection switch is changed from 'SET' to 'RUN' or from 'MODE'
to 'RUN', the set sensitivity or the contents of each mode setting are stored in an
EEPROM. Since the EEPROM has a life time, the sensitivity 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.

Jog switch Operation
In 2-level teaching, it sets the sensitivity.
In limit teaching, it stores the incident light intensity in the object absent condition.
Each item is selected and the item or the contents of each item to be set is decided.
In limit teaching, it determines the direction of shift of the sensitivity.
It does fine adjustment of the set sensitivity.
The contents of each item are selected.
In full auto-teaching, it sets the sensitivity.

Functions of level indicators
If the mode selection switch is set to 'SET' or 'RUN', the level indicators show the
position of the set sensitivity level. However, if the mode selection switch is set to
'MODE', the level indicators show the output operation/emission frequency/timer
settings.
*: The sensitivity level is changed in the range 0 to 999 within the sensor.

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 0.3mm
2
, 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.

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.
