Notes Notes

You can adjust the spot diameter and detection

distance by changing the amount of fibers inserted,

but if you jam the fibers in too far, the tip of the fibers

will become separated from the lens.

Tighten the fiber nut after

setting the fiber and NF-DA06

in place in order to fix them so

that they do not move because

of vibrations, etc.

Use M3 cup-point set screws to

mount NF-DA06 if you want to

use set screws.

Insert fibers into NF-DA01/

-DA02/ -DA03/ -DA04/ -DA05

as far as they will go.

You can adjust the spot diameter and detection

distance by changing the amount of fibers inserted.

Tighten the nut after setting the

fiber and NF-DA07 in place in

order to fix them so that they do

not move because of vibrations,

etc.

To clean NF-DW02, use a soft cloth to wipe away all

liquid on the head and bracket. Be sure to check for

condensation on the detector.

If the fibers on NF-DW02/ -TF01 are too short, the

detector may not receive the correct amounts of light

and may not be able to detect consistently.

Use the bracket designed especially for the

NF-DW02 in order to avoid mistakes such as forget-

ting to attach something. Otherwise, the detector

may not be able to detect consistently.

If you use a PVC bracket on the black mat parts on

the steel case, the device cannot detect mistakes, so

perform a thorough check before using the device.

Be careful not to damage exterior of the fibers when

you cut the protective tubes.

Only set NF-DW02 sensitivity after mounting the

completely dry head to the bracket and attaching the

fibers to the amplifier. Adjusting the fiber connection

or position after adjusting sensitivity changes the

amount of light that enters and causes inconsistent

detection.

If you altered fiber connection or position while clean-

ing the device, make sure to adjust amplifier sensitiv-

ity.

The amount of light may decrease when the device is

used for long periods of time at high temperature and

humidity.

Liquids that are not compatible with NF-DW02 head

material (PFA) may cause air bubbles to flood the

detector. This causes inconsistent detection, or

makes consistent detection take more time. Test the

liquid you are examining before beginning.

Make sure that the NF-DW02 bracket does not have

any scratches, dirt or grime, or deformities when you

clean it.

Water droplets on the detection surface may affect its

detection capability. Avoid using this device in places

where it can come into direct contact with water.

Remember to check for condensation on the outside

of pipes.

Mounting Chemical-Resistant

Angled-Head Fibers (NF-TY05)

Use M3 screws and tighten

them to torques of 0.3Nm or

smaller.

There are two types of slits that come with these

products (the slit that comes with the NF-TZ01/

-TZ02 is one of them). These slits help detecting tiny

objects and prevent saturation when using the fibers

at close range. However, applying adhesive slits

shortens the detection distance.

Align the pointed end of the adhesive slit to the top of

the fiber and apply it as shown in the diagram below.

Keep the heat-resistant fiber part at least 150mm

from the boundary of the ordinary-temperature zone

as shown below in order to protect amplifiers.

Do not directly expose amplifiers to radiation heat or

hot air.

The metal bracket on the tip of the heat-resistant fiber

(up to 350℃) and stainless steel sheath may change

color when used at high temperatures, but this does

not affect their detection capability.

①

Pull the positioning lever

open, in the direction of the

arrow.

②

Push the moveable part in the

direction of the arrow, loosen

the zip tie, and readjust the

mounting position.

③

Close the positioning lever so

that it will not loosen.

You must reset the sensitivity after readjusting the mounting position.

The positioning lever is for readjusting the position on this device, not for tightening the zip

ties. Tightening the zip ties while the positioning lever is open and then closing the lever will

damage the fibers.
