Mounting with an Alignment Tool
The HEDS-8905 and HEDS-8906 alignment tools are rec-
ommended 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 fi x 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
3. Insert mounting screws through module and thread
4. Slide alignment tool over codewheel hub and onto
5. While holding alignment tool in place, tighten screws
6. Remove alignment tool.
Mounting with Aligning Pins
The HEDS-9040 and HEDS-9140 can also be mounted us-
ing aligning pins on the motor base. (Hewlett-Packard
does not provide aligning pins.) For this confi guration,
Side A must be used as the mounting plane. The align-
ing recess centers must be located within the 0.005 in. R
Tolerance Circle as explained above. Figure 5 shows the
