MOUNTING
Mount the fiber on a pipe with the attached tying bands and
anti-slip tubes as shown in the figure below.
Make sure that the release lever is retracted (position as
shown in the figure) before mounting.
Fasten two tying bands, as shown, and cut off the excess portions.

Release lever Tying band
2- 3.2 mounting holes
If other tying bands are to be used, the dimension
the figure below should be 2.5mm or less.
In case of mounting using the two mounting holes, use M3
screws, plain washers, and spring washers.
The tightening torque should be 0.3N m or less.
Please arrange the M3 screws, plain washers, and spring
washers separately.
In case of mounting on the pipe with tying bands, the fiber
position can be easily adjusted with the release lever.
Adjustment Release lever
Unlock the release lever (in
the direction of the arrow).
Press the movable center
holders forward to loosen the
tying bands and adjust the
position.
Lock the release lever to its Press
original place.

Notes: 1) Whenever the mounting position is changed, adjust the sensitivi-
ty again.
2) The lever mechanism must be used only to adjust the position,
and not for tightening the tying bands. If tying bands are
tightened while the lever is open, and then the lever is locked,
the fiber may be damaged.

CONNECTION TO AMPLIFIER
Put the fiber cable with white stripe into the beam-emitting
side, and the fiber cable without white stripe into the beam-re-
ceiving side. If the connection is wrong, correct detection is
not possible.

SENSITIVITY ADJUSTMENT
For the amplifiers, refer to the respective amplifier's Instruction
Manual.
Do not move or bend the fiber cable after the sensitivity setting.
Detection may become unstable.
When using in combination with the FX-301(P), the
FX-301(P)-HS or the FX-305(P)

When the threshold value adjuster is turned clockwise, the
MODE key threshold value increases. When the threshold value adjuster is
turned counterclockwise, the threshold value decreases.

Notes: 1) In order to protect the mechanism, the sensitivity adjuster idles when
over turned, which may result in a backlash of 1 to 2 divisions.
: Shifting is possible
2) Depending upon the sensing conditions, stable sensing may be possible
: Shifting is not possible at a position which is slightly shifted from the optimum sensitivity point.
3) FX-311(P) incorporates the assist function which is useful for
sensitivity adjustment. For details, refer to the instruction manual
enclosed with FX-311(P).

CAUTIONS
Fit the fiber head to the pipe securely, otherwise the operation
may be erroneous.
(Threshold value) (Threshold value)
Take care that no dew condenses on the pipe's sensing
surface or the pipe's inside wall and that no bubble attaches
on the pipe's inside wall, since it can affect the operation. If a
liquid drop flows down across the sensing point or an air
bubble sticks on the wall at the sensing point, the operation
may be erroneous. Make sure that no bubble arises in the
liquid, and that no dew or liquid drop is present on either
surface of the pipe wall.

Neither FD-F4
tion should be avoided at any place where it could come in
direct contact with water or chemicals.
: Lights up : Turn off Do not apply excessive tensile force to the fiber cable.
Operation Operation indicator
Bending radius of the fiber cable must be R10mm or more. If
the bending radius is smaller than the specified value, the
sensing performance may deteriorate.
Take care that the sensor is not directly exposed to fluorescent
lamp from a rapid-starter lamp, a high frequency lighting device
or sunlight etc., as it may affect the sensing performance.
