▍Safety information
DANGER
Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury
WARNING
Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury
CAUTION
Indicates a potentially hazardous situation which, if not avoided, may result in minor injury or property damage
Please read the safety information carefully before the use, and use the product correctly.
The alerts declared in the manual are classified into
Danger, Warning
and
Caution
according to their importance
• The input/output terminals are subject to electric shock risk. Never let the input/output terminals come in
contact with your body or conductive substances.
DANGER
• The contents of this manual may be changed without prior notification.
• If you use the product with methods other than specified by the
manufacturer, there may be bodily injuries or property damages.
• Avoid continuously switching the power source On and Off.
• Use a dry cloth to wipe off the substance when cleaning the
lens or cases. Never use thinner or organic solvents.
• Do not use this product at any place with much dust, vibration or impact.
• Before inserting power source, make sure that the circuit wiring
is properly connected.
• In the case of wiring loaded inductors such as DC Relay and
others to output, use diode, varistor and others to prevent surge.
• To avoid malfunction caused by noise, do not put high voltage
or power line with sensor wire in a same conduit.
• Make its wiring be shorter as possible and wire extension shall
be within 30 m.
• Do not apply a strong tension to the fiber optic cable.
• Do not curve the fiber optic cable over tolerable bending.
• Do not make any scratch on the cable.
• Consider the fact that the sensing distance may be varied
in accordance with the size, color, surface condition,
material, glossy, non-glossy or others of a sensing object.
• Prevent strong disturbance light such as sunlight and
others which directly enter into the directional angle of
the sensor by putting a glare shield.
• In the case of using multiple sensors (more than 2 sensors), there
is a possibility of malfunction caused by mutual interference so,
for Through-Beam type, sensors shall be installed in a divergent
way or there shall be proper distance between them.
• When using the Switching Power Supply as the power source,
earth the Frame Ground (F.G) terminal and be sure to connect the
noise-eliminating condenser between 0 V and F.G.
• To prevent defection or malfunction of this product,
supply proper power voltage in accordance with the rating.
• Since this product is not designed with explosion protective
structure, do not use it at any place with flammable or explosive gas.
• Remove this product while the power is off. Otherwise,
it may cause malfunction or electric shock.

■ 2 Contact teaching method
▍
Operation level setting
There are two types in operation setting level which are 2 contact teaching and auto teaching. "2 contact teaching method"
is the method that sets the operation level by teaching the 2 contacts when it is in state where sensing object is in presence
and in absence. This method is most widely used.
■ How to use auto teaching
• Use auto teaching without stopping the line when set the operation level in the state where sensing object is moving.
Function
Information
①
• Install the fiber within the sensing range.
• Pressing the ▷(AT/C) button for 3 sec will enter into the "auto operation level" setting mode.
Here BAR-LED and STB-LED start to flicker.
②
• It runs the auto teaching function automatically for approx 10sec and return to the operation
mode. Here BAR-LED and STB-LED stop flickering.
(this is only applied under the condition where sensing object moves at least twice in 10 sec)
Order
Information
①
• Install the fiber within sensing range.
• Select the [slide switch 1] as L.ON (Light-on) side or D.ON (Dark-on) side.
• Pressing the ◁(M.T/E) button for 3 sec will enter into the "operation level setting mode".
Here BAR-LED and STB-LED start to flicker.
②
• Pressing the ◁(M.T/E) button instantly when sensing object is not in presence
(max amount of light state) will save the max value of light.
③
• Pressing the ▷(A.T/C) button instantly when sensing object is in presence (min amount of light state)
will save the min value of light.
④
• Pressing any of two buttons for 3 sec will return to the operation mode.
Here, BAR-LED and STB-LED will stop flickering.

Name of parts
• Setting and operation selecting slide switch
SET : This is SETUP function which is used for setting the
TIME and other functions
L.ON : Light ON operation mode which of control output
becomes ON when an amount of light is more than
the set value.
D.ON : Dark ON operation mode which of control output becomes
ON when an amount of light is less than the set value.
• Delay time selecting slide switch
OFD : OFF Delay which of when the input light level is OFF,
output will become OFF due to the delay of 40 ms
OND : ON Delay which of when the input light level is ON,
output will become ON due to the delay of 40 ms
NOR : Generate the output immediately depending on the
input light state
TRIG : With the increment of derivative running external
input, it checks for the input light state and then
generates the output (Delay Time setting possible)
GATE : It generates the output when the period running
external input and input light become ON state.
