E39-F10
 Fiber Connector
Use
 the following procedure (refer
 to the figure) to connect fibers via
the
 Fiber Connector
.

Each fiber should be as close as possible before they are con-
nected.
Sensing
 distance will be reduced by approximately 25% when fibers
are
 connected.
Only fibers with 2.2 mm dia. can be connected.
Protective Spiral T
ube
Insert
 a fiber to the Protective Spiral T
ube from the head connector
side
 (screwed) of the tube.

Fiber Unit
Push the fiber into the Protective Spiral Tube. The tube should be
straight
 so that the fiber is not twisted when inserted. Then turn the
end
 cap of the spiral tube.

Use
 the attached saddle to secure the end cap of the Protective Spi

ral Tube. To secure the Protective Spiral Tube at a position other
than
 the end cap, apply tape to the tube so that
 the portion becomes
thicker
 in diameter
.

E39-F3A
 Reflective Unit Lens
When
 the E39-F3A is attached to the fiber
, the E3X can sense
 the
light reflected from
 the interior of the E39-F3A. If this happens, ad
-
just
 the sensitivity of the E3X Amplifier with Sensitivity Adjustor
.
Place a sensing object or white paper at the sensing distance set
and
 adjust the insertion length of the Fiber Unit to the E39-F3A so
that
 the light spot is as small as possible. Then
 fix the position of the
Fiber
 Unit with the hexagonal wrench (attachment)

1. Remove
 the cover of the E3X.
2.
 Attach the E39-G3 (refer to the figure).

Cover
3. After the cover is attached to the case, turn the knob of the
E39-F3A clockwise or counterclockwise once. To confirm
that
 the knob has been set properly
, turn the knob clockwise
or counterclockwise until you hear a click (8 turns max. are
necessary).
Note:
E3X looses watertightness if E39-G3 is attached (the en-
closure
 rating will be IP50).
