This product is a Liquid Type Identification Sensor that can discriminate between
water and other liquids in addition to detecting liquids. It can also be used todistinguish between two types of liquids other than water, depending on the type ofliquid. If water is set to external output 1 (OUT1), and liquids other than water are set
to external output 2 (OUT2), and they can be output separately. This will result in, forexample, it can be used not to detect with water but to detect with oil.
The detector is made of synthetic quartz and PFA, and can be used with a liquidthat does not corrode or damage these.
In addition, since the detector uses optical fiber, it can also be used in explosionproof areas.
※The control unit is not explosion-proof.

2. Handling precautions for fiber sensor! Caution!
! Caution! 注意(1) Do not look directly into the light of the floodlight and detector of the control unit.
Otherwise, it may hurt your eyes.
(2) The optical fiber may be damaged or broken if you do the following. Please handlewith care.
・Pull / step・・・Tensile strength [160N]

・Fold・・・Minimum bend radius [2mm]・Heat・・・Heat resistance 105 ℃ (Core material PMMA)※Operational temperature : -10 to 60 ℃
! Caution! 注意・Scratch(3) If the lens is scratched, the detection performance will be affected. Please handle
with care so as not to damage it. Also, if there is dust or dirt on it, it may not bedetected correctly. If it is dirty, wipe it with a clean cloth and use clean air to removedust.

4.1 Detector(1) Secure the bracket in close contact with the installation surface. The mounting holedimensions are shown in the figure below.

※ Be sure to use the specified bracket.
※ Secure the bracket on a flat surface with no irregularities. If there isunevenness, it may not be detected normally.
※ If you install it on a black color floor, you can get more stable operation.
When installing on a non-black color floor or uneven floor, it is recommended
to insert the attached black PVC sheet between the bracket and the floor.
(2) Push the detector body all the way into the bracket and fix it so that it will notcome off.
！注意! Caution！注意! Caution！注意! Caution

If the main body is floating from the bracket, it will not operate normally. Make sure
to push it all the way in.
Since the main body of the detector is made of resin, handle it with care so that it
will not be deformed, scratched or damaged by applying excessive force.
The detector is made of synthetic quartz. Be careful not to rub it on a hard surface
such as stone or concrete as it will scratch it. In addition, if the floor is made of a soft
material such as vinyl chloride, it may damage the floor, so be careful.

(3) Mounting to the control unit
① Raise the lock lever.
② Make sure to insert the fiber of the detector
into the fiber insertion slot as far as it will go.
③ Return the lock lever to its original
Direction to secure the fiber. (Locked)- 5 -FiberLight

Control unit

(1) Mounting on DIN rail
① Hook on the rail the claw on the insertion
side of the detector.
② Push in until the hook clicks.
(2) Removing from DIN rail
① Push the main body in the direction of ①.
② While doing ①, lift in the direction of ②.

! Caution！注意If the operation is not normal, please check it referring to the following.
(1) If nothing is displayed on the control panel, there is a possibility of poorconnection or a load short circuit (damage to the control unit due to overvoltage
or overload). Immediately stop using the product and check the wiring and load.
(2) If it is displayed on the control panel but the output does not work properly,
please check the wiring and load because there is a possibility that the transistor
inside the control unit is defective due to wiring failure or overload.
(3) If the detector is not fully inserted in the bracket, detection may not be performed
normally. Please insert the detector firmly into the bracket again.
(4) If the fiber of the detection unit is not firmly inserted into the fiber insertion slotof the control unit, the amount of light received may be low, and the displayed
value may be too small or 0, making it impossible to detect normally.
！警告! Warning

Do not look directly into the light from the floodlight or detector of the controlunit. It may hurt your eyes.

! Caution！注意Since this sensor uses a photo device, it may not be detected properly when
exposed to strong external light.
There is no problem with normal room temperature illuminance, but if there isa possibility of emitting strong light near the detector, or if you use it outdoors,
we recommend that you take measures such as blocking the light.

! Caution！注意If dust, dirt, water, oil, etc. adhere to the lens at the tip of the detector, adetection error may occur. In that case, wipe off the dirt with a rag etc. If it isvery dirty, wipe it off with a rag soaked in alcohol or wash it with a neutral
detergent.
If you wash it with detergent, wash it off thoroughly so that no detergent
remains on the lens. Please wipe off the water after cleaning.

5.1

Threshold setting(1) If you press the [< / >]button during normal display, the threshold flashes toindicate that it is adjustable.
(2) Please use the [< / >] button to adjust to any value.
Normal state (Run mode)If you press the mode button or if there is
no operation for about 5 seconds after
the setting is completed, the normal
display (Run mode) will reappear.

(1) When you press the[□] button, the channel (output) number of the migration
destination blinks and switches.

Display switching(1) You can switch from the numerical display to the percentage display by pressing

the[<] button and the[□] button at the same time.

Numerical display

Percentage display(2) While the percentage is displayed, you can set the value to 100 by pressing the[>] and[□] button at the same time.

6. Recovery after liquid detection! Warning！警告The leaked liquid may be mixed or generated with acids, alkalis, chemical products,etc. Those who are familiar with the liquid used and the environment should pay closeattention to the work.

! Caution！注意

Be sure to use chemical-resistant or oil-resistant gloves for work.

! Caution！注意

For chemicals that require the use of protective glasses, protective masks, etc., besure to take necessary protective measures.
(1) Wipe off any leaks around.
(2) Remove the detector from the bracket and wipe off the leaked liquid on the bodyand bracket. Clean the detector if necessary.
(3) Push the detector into the bracket to secure it.
(4) Check that the values and output of the detector are normal.
