PRECAUTIONS FOR PROPER USE.

Fiber

FD-F4and FD-F9liquid 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 A shown in the figure below should be 2.5 mm 0.098 in or less.

•In case of mounting using the two mounting holes, use M3 screws, plain washers, and spring washers.

The tightening torque should be 0.5 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.

3Lock the release lever to its original place.

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-F4or the FD-F9is waterproof or 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-MR2is set on the fiber head at the desired depth, tighten

the attached nut securely.

•To mount FX-MR2with 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-MR6on the fiber head until the fiber is fully inserted.

The tightening torque should be 0.29 N m or less.

Notes: 1) Whenever the mounting position is changed, adjust the sensitivity 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.
