INSTALLATION
Refer to the back page of these instructions for outline and
mounting dimensions.
Equipment needed for installation
Supplied:
AV45 Encoder
Optional:
Foot Mount Kit
Thread Locker (blue)
Not Supplied:
M5 T-handle hex wrenches or torque wrench with M5 bits
Dial Indicator Gauge
Caliper Gauge
The encoder must be driven by a positive drive rather than a friction
drive. The following means of coupling are acceptable when properly
installed: Direct Coupling.
With a direct drive, use a flexible disc coupling and align the shafts as
accurately as possible. For motors with a pre-aligned flange, it is also
acceptable to use a “spider” or “jaw” coupling type. If a rubber slinger
disc is used, position it on the shaft so it will rotate freely.
CAUTION
Do not force or drive the coupling onto the shaft, or
damage to the bearings may result. The coupling
should slide easily on the shaft. Remove nicks and
burrs if necessary. Consider driving shaft endplay
& axial movement when positioning coupling.
For more details on alignment specifications, measurement tech-
niques, and special considerations in specifying and installing drive
components, refer to separate installation instructions in the Avtron
PULSE GENERATOR HANDBOOK.
B10 FACE MOUNTING INSTRUCTIONS
1) Apply anti-seize compound [copper], included, to inner
circumference of coupling (both motor and encoder side).
2) Loosen set screws in coupling and apply thread locker to set
screws.
3) Place coupling on motor shaft, inserting to depth per
manufacturer’s instructions.
4) Attach coupling to motor shaft using set screws per
manufacturer’s instructions.
5) Bolt mounting flange (flowerpot) to motor C-Face, using thread
locker with fasteners, included.
6) Slide encoder shaft into other side of coupling. DO NOT
FORCE. Ensure keyway aligns with coupling set screw
location.
7) Ensure C-Face on mounting flange matches and aligns with
encoder C-Face precisely.
8) Apply thread locker to hex cap screws.
9) Align bolt holes of encoder and flange, thread in (4) hex cap
screws, using lock washers.
10) Tighten set screws on encoder side of coupling.
FOOT MOUNTING INSTRUCTIONS
Equipment needed for installation
Supplied:
1. Foot Bracket
2. Soc. Hd. Cap Screw

Not Supplied:
M5 Hex Wrench
Dial Indicator
The B10 flange / face is the preferred mounting method for the AV45.
In certain cases, however, it may be necessary to foot-mount this unit.
The optional foot mounting bracket kits, Option 1, 2, or 3, will be re-
quired for standard installations or replacement of foot mounted Toshi-
ba TS2113N, Hubner HOG & OG, and FG4 units. Read all of the fol-
lowing instructions and the Avtron PULSE GENERATOR HANDBOOK
prior to beginning any work.
The AV45 performance and life will be directly affected by the installa-
tion. Following this sequence of steps is recommended.
1) Clean and inspect motor/driver shaft. Do not use force to
assemble coupling onto motor/driver shaft. The foot mounting
bracket must be secured to a flat, rigid, vibration free steel or
aluminum base which can be machined to accept the
mounting hardware.
2) Temporarily mount the AV45 to the foot bracket, install the
coupling to the AV45 and driver, and verify that the location is
suitable for installation.
3) If the AV45 encoder, bracket and coupling are suited to the
area, check motor/encoder shaft alignment with a straight
edge from multiple positions around the shaft circumference to
verify that it meets specifications.
4) While maintaining alignment, precisely mark the position of the
foot bracket on its mounting base.
5) Remove the AV45. Transfer punch or layout the mounting hole
pattern as indicated on outline drawing.
6)
Machine through holes or tap holes
in center of base slots to give some degree of freedom in final
alignment.
7) Reinstall the AV45 with the flexible coupling loosely in place,
and tighten down all mounting hardware. Check
motor/encoder shaft alignment with a straight edge from
multiple positions around the shaft circumference to verify that
it meets specifications. Use thread locker supplied on cap
screws which mount AV45 to foot bracket.
8) Ensure any flat or keyway on the motor and encoder shaft are
aligned with the set screw holes of the flexible coupling. Apply
thread locker to coupling set screws and tighten per
manufacturer’s recommendations.
9) Recheck alignment and tighten all hardware after first several
hours of operation.
MODIFICATION
The AV45 can be modified in the field to easily adapt to new
applications.
TO CHANGE ELECTRICAL CONNECTOR STYLE:
1. Remove electrical power and disconnect the mating plug.
2. Unscrew the (4) M5 screws (4mm hex).
3. Pull the connector header away from the encoder gently.
4. Disconnect the ribbon connector to the encoder body.
5. Connect the ribbon connector to the new connector header
6. Attach the new connector header to the encoder using the (4)
M5 screws. Tighten to 30 in-lbs [3.4n-m]. Be sure the ribbon
connector fits in the open pocket under the header and is not
crushed or pinched by the connector header.
