3MOUNTING
How to mount
1. Fit the rear part of the mounting section of
the amplier on a DIN rail.
2. Press down the rear part of the mounting
section of the unit on the DIN rail and t the
front part of the mounting section to the DIN
rail.
2. Press down

How to connect the ber cable
● Mount the ber cables in the state power is not supplied.
●Be sure to t the attachment to the bers rst before inserting the bers to the
amplier. For details, refer to the instruction manual enclosed with the bers.
● Insert the ber cables slowly into the inlets until they stops. Excessive force may
damage the product.
1. Snap the fiber lock lever down till it stops
completely.
2. Insert the ber cables slowly into the inlets
until they stops. (Note)
3. Return the fiber lock lever to the original
position till it stops.

Fiber for emitter
Note: With the coaxial reective type ber, insert the single core ber cable into the beam-emitting inlet “P” and the
multi-core ber cable into the beam-receiving inlet.
If they are inserted in reverse, the sensing performance will deteriorate.
4 INSTALL MORE AMPLIFIER OF SERIES CONNECTION TYPE
(Connection type only)
●Make sure that the power supply is OFF while adding or removing the series
connection type.
●This product is not equipped with an automatic interference prevention function.

PRO MODE.”
●In case 2 or more the series connection types are connected in cascade, make
sure to mount them on a DIN rail.
●In case installing additional amplifier of series connection type, the maximum
15 the series connection types using sub cables (optional) can be added to an
amplier using a main connection cable. (optional)
●When connecting 2 or more the series connection types in cascade, use the sub
cable (optional) for the second series connection type onwards.
For mounting and removing the amplier, refer to “ 3MOUNTING.”

15 CAUTIONS
●This product has been developed / produced for industrial use only.
● Make sure that the power supply is OFF while adding or removing the ampliers.
●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 be damaged.
●Take care that short-circuit of the load or 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.
● The specication may not be satised in a strong magnetic eld.
●Verify that the supply voltage variation is within the rating.
●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.
●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.
●The ultra long distance (U-LG, HYPR) mode is more likely to be affected by
extraneous noise since the sensitivity of that is higher than the other modes. Make
sure to check the environment before use.
●Do not use during the initial transient time (FAST, STD: 0.5 sec., LONG, U-LG,
HYPR: 1 sec.) after the power supply is switched ON.
●When extending the cable length, use a cable with a conductor cross-sectional
area of 0.3 mm2or more. Note that the maximum allowed cable length is 100 m.
However, in order to reduce noise, make the wiring as short as possible.
● Set the power supply voltage by considering the voltage drop resulting from the
conduction resistance of the cable.
●Make sure that the cable joint is not applied with stress, such as strain caused by
forcible bending or pulling.
●This product is suitable for indoor use only.
●Avoid dust, dirt, and steam.
●Take care that the product does not come into contact with organic solvents such
as thinner.
●Take care that the product does not come into contact with strong acids or alkalis.
●Take care that the product does not come into contact with oil or grease.
●This product cannot be used in an environment containing inflammable or
explosive gasses.
●Never disassemble or modify the product.
●This product adopts EEPROM. Settings cannot be done 100 thousand times or
more because of the EEPROM’s lifetime.
