Install the sensor.
1.Insert the plate (D) into the sensor (C)
that has the M6 nut (1). Screw the slit
(A) fully. Unscrew the slit slightly until
the sensor is positioned with its
indication upwards, and the R-shaped
section of the slit is positioned in the
specified position. Fix the sensor with
M6 nut (1).
2. Put a new bushing (2) first. Half
tighten the Hexagon-socket-head
setscrew (3).
<Caution.>
1. Light-emitting: Indication in red
Light-sensing : Indication in blue
2. Slits are different between light-
emitting and -sensing sides. (See
pictures)
3. For the position of the R-shaped
section of the slit, see the pictures.

Light-axis adjustment (Preparation 1)
1. Adjust the gap between the block A
and the plate B,using the adjusting bolts
(1) until the gap becomes 0.
2. Keeping the gap 0, press the block
gauge (10 mm) against the reference
surfaces of the block A and the block B.
Level the block A and the plate B by
aligning them with the block gauge. Fix
them by tightening the adjusting bolts
(1).
<Caution>
Basically it is not necessary to position
the light-sensing plate.

adjusting-power box)
Loosen the M4 bolts (1). Moving the light-
emitting-axis horizontally, align the laser light
with the center of the horizontal slit of the
FM-1962 (2) (2. component-thickness-
measuring-unit-light-axis-adjusting jig).
Tighten the M4 bolts (1).

(2. component-thickness-

adjusting jig)
Loosen the M6 nut (1). Turn the light-
emitting-axis eccentric pin to align the
laser light with the center of the vertical
slit of the FM-1962 (2) (2. Component-
thickness-measuring-unit-optical-axis-
adjusting jig). Find a position at which
the amplifier value (light-sensing
amount) is 2000 or more. Tighten the
M6 nut.
If the laser light is positioned far from
the vertical slit in the vertical direction,
loosen the bolt (3) and align the light-
axis with the groove.
