How to mount the amplifier

Fit the rear part on the attached
amplifier
(MS-DIN-2) or a 35mm width DIN rail.
Press down the front part of the
amplifier on the amplifier mounting
bracket (MS-DIN-2) or the DIN rail
to fit it.

How to remove the amplifier

Push the amplifier forward.
Lift up the front part of the
amplifier to remove it.

How to connect the fiber cables

Snap the fiber lock lever down.
Insert fiber cables slowly into the
inlets until they stop. (Note 1)

original position, till you feel a

Notes: 1) In case the fiber cables are not inserted to a position where they stop, the
sensing range reduces.
2) With the coaxial reflective type fiber, such as, FD-G4, FD-FM2, insert the
center fiber cable (single-core) into the beam-emitting inlet and the outer fiber
cable (multi-core) into the beam-receiving inlet. If they are inserted in reverse,
the sensing accuracy will deteriorate.
Beam-receiving part
Beam- emitting part
Make sure to carry out the wiring in the power supply off condition.
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 connect-
ed 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.
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 circuit. 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
Avoid dust, dirt, and steam.
Take care that the product does not come in direct contact with
water, oil, grease or organic solvents, such as, thinner, etc.
