1. Replacement of Head Unit
1.1.2 Detachment of Head Unit
(1) When the four bolts (M5L16) are removed, it becomes possible to detach the head
unit from the head mounting section of the beam.
(a) The positioning pins may interrupt the detachment slightly.
(b) Two people are required for this work.
One person should hold the head unit securely.
(c) When the head unit is attached, be sure not to touch the HL/NL origin and limit
photosensors. Otherwise, the photosensors may be damaged.
1.2 Attachment of Head Unit
1.2.1 Attachment of Head Unit
Attach the head unit to the head mounting section with four bolts (M5L16) as shown in Fig.
E4.
1.2.2 Connection of Head Cover Wires
(1) Follow the reverse order of the steps described in "1.1.1 Disconnection of Head
Cover Wires" for the wiring and piping.
The wires must be bundled together.
(2) Attach the head cover.
(a) Be sure to bundle the excessive wires together on the head multiaxis board, so
that the wires cannot be moved.
(b) When the head unit is attached, be sure not to touch the HL/NL origin and limit
photosensors. Otherwise, the photosensors may be damaged.

(2) PEC Recognition Camera & Beam Offset
(3) Component Recognition Camera Offset (Offset Teaching)
(4) Head Rotational Angle Axis Offset
(5) Head Rotational Center Offset/Reference Mark Position Offset
(6) Fly Recognition Camera Offset
(7) Nozzle Position Offset
(8) Nozzle Level Offset
(9) NL-Axis Origin Offset

2. Replacement of Linear Measure Sensor
Chapter 5 Head Section
Linear Measure Sensor
2.1 Detachment of Linear Measure Sensors
(1) Remove the two bolts (M1.6L5) of the
small diffusion plate (inner side)
(2) Remove the two bolts (M1.6L5) on the
light emitting side of the linear measure
sensor and detach the linear measure
sensor on the light emitting side from the
motor side.
Do not detach the linear measure sensor on the light receiving side.
Disconnect the linear measure sensors connected with the connectors. (Figs. E6 and E7)
(3) Detach the linear measure sensor amplifier board located beside the head (the upper
area of the head).
Heads #1 and #4 are
located inside and Heads
#2 and #3 outside.
Remove the three
connectors and the four
setscrews.
The linear measure
sensor amplifier board
and the linear measure
sensor on the light
emitting side are
assembled together (regarded as one unit). When it is required to replace either one
of them with a new one, be sure to replace both of them with new ones.
