Mounting with an
Alignment Tool
The HEDS-8905 and HEDS-8906
alignment tools are recommended
for mounting the modules with
Side B as the mounting plane. The
HEDS-8905 is used to mount the
HEDS-9140, and the HEDS-8906
is used to mount the HEDS-9040.
These tools fix the module
position using the codewheel hub
as a reference. They will not work
if Side A is used as the mounting
plane.
The following assembly procedure
uses the HEDS-8905/8906
alignment tool to mount a HEDS-
9140/9040 module and a HEDS-
5140/6140 codewheel:

Instructions:
1. Place codewheel on shaft.
2. Set codewheel height by
placing alignment tool on motor
base (pins facing up) flush up
against the codewheel as shown
in Figure 3. Tighten codewheel
setscrew and remove alignment
tool.
3. Insert mounting screws
through module and thread into
the motor base. Do not tighten
screws.
4. Slide alignment tool over
codewheel hub and onto module
as shown in Figure 4. The pins of
the alignment tool should fit
snugly inside the alignment
recesses of the module.

place, tighten screws down to
secure module.
6. Remove alignment tool.
Mounting with Aligning
Pins
The HEDS-9040 and HEDS-9140
can also be mounted using
aligning pins on the motor base.
(Hewlett-Packard does not
provide aligning pins.) For this
configuration, Side A must be
used as the mounting plane. The
aligning recess centers must be
located within the 0.005 in. R
Tolerance Circle as explained
above. Figure 5 shows the
necessary dimensions.
