PRECAUTIONS FOR PROPER USE
Fiber
FD-F4
and FD-F9
liquid level sensing fiber
Mounting
Mount the fiber head 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 in
the fig.) before mounting.
Fasten two tying bands, as shown, and cut off the excess
portions.
If other tying bands are to be used, the dimension
in the figure below should be 2.5 mm
In case of mounting using the two mounting holes, use M3
screws, plain washers, and spring washers.
The tightening torque should be 0.5 N 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.
Adjustment
1 Unlock the release lever
(in the direction of the
arrow).
2 Press the movable
center holders forward
to loosen the tying
bands and adjust the
position.
3 Lock the release lever
to its original place.
Notes: 1) Whenever the mounting position is changed, adjust the sensitivity again.
Notes:
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.

Cautions
Liquid in a pipe which is not transparent cannot be sensed
correctly.
Unclear or viscous liquid may not be sensed.
Fit the fiber head to the pipe securely, otherwise the
operation may be erroneous.
Take care that no dew condenses on the pipe's sensing
surface or the pipe's inside wall and no bubble attaches on
the pipe's inside wall, since it can affect the operation.
Neither the FD-F4
or the FD-F9
chemical-resistant. Installation should be avoided at any
place where it could come in direct contact with water or
chemicals.
Do not apply excessive tensile force to the fiber cable.
Cautions for FX-MR2 zoom lens usage
The spot diameter and the sensing range are adjustable
by the screw-in depth as follows.
After FX-MR2 is set on the fiber
head at the desired depth, tighten
the attached nut securely.
To mount FX-MR2 with a set screw,
use a M3 set screw (cup point). The
tightening torque should be 0.29
N m or less.
Caution for FX-MR3, FX-MR6 finest spot lens usage
Screw FX-MR3, FX-MR6 on the fiber head until the fiber is
fully inserted.
The tightening torque should be 0.29 N m or less.
