INSTALLATION CONSIDERATIONS
See page 3 and drawing on last page for shaft engagement rules.
Shaft may include keyway, but should not be flatted.
The HS35M offers optional Avtron flexible anti-rotation tethers/
brackets which will permit the encoder to tolerate ±0.1" of shaft end
float/axial movement. For larger movement, select tether option "G"
from the table below.
CAUTION
Be careful not to damage clamping fingers of hollow
shaft during handling. Do not tighten clamping collar
before installation onto motor shaft.
WARNING
Installation should be performed only by qualified
personnel. Safety precautions must be taken to ensure
machinery cannot rotate and all sources of power are
removed during installation.
WARNING
DO NOT USE ANAEROBIC THREAD LOCKER COMPOUNDS
ON THE HS35M. Use of Loctite 222, 242 or other
anaerobic thread locking compounds on the housing can
cause failure of the HS35M housing.

INSTALLATION

Refer to the back page of these instructions for outline and mounting
dimensions. Also available: EU (European Union)
Installation Sheet, Torque Arm Installation Sheet, and Basket Mount
Installation Sheet. NOTE: For metric bore sizes, the encoder is provided
with metric size hardware. For US bore sizes, the encoder is provided
s
with US size hardware.
1)
Disconnect power from equipment and encoder cable.
2)
Use caliper gauge to verify motor shaft is proper diameter and
.
within allowable tolerances: +0.000", -0.0005" [+0.00,
-0.13mm].
3)
Clean machine shaft of any dirt and remove any burrs.
4)
Use dial indicator gauge to verify the motor shaft Total
Indicated Runout (TIR) <0.002" [0.05mm].

5)
Install the anti-rotation bracket to the face of the encoder
using 8-32 screws and lock washers.
6)
Loosen clamping collar screws.
NOTE
These screws have factory applied thread locker,
no further thread locker application is required.
6)
Optional: for resizing HS35M 1" bore to fit smaller
diameter shafts: Insert shaft sizing insert into encoder. DO
NOT FORCE.
7)
Test Fitting: carefully slide the encoder onto the shaft to verify
fit. Ensure a minimum of 1/8" between encoder and mounting
surface. DO NOT FORCE. Encoder should slide on easily. If
the encoder does not fit easily, remove it, verify shaft size, and
check for burrs and shaft damage.
8)
Special Note for shaft in HS35M without a shaft insert ONLY:
Remove encoder, apply anti-seize compound to shaft and
reinstall encoder, leaving a minimum of 1/8" between motor
face and encoder (see "Shaft Engagement").
9)
Tighten screws on clamping collar evenly until snug,
then tighten each screw to 35-50 in-lb [4-6 Nm]. DO NOT
USE A STANDARD RIGHT ANGLE WRENCH. Use only a
T-handle hex wrench or torque wrench with hex bit. Note:
Units shipped with a metric bore size require a 4mm
T-handle hex wrench; units with US size bores, a 3/16"
T-handle hex wrench.
10) For all motor mount options other than 8.5" C-face: Snap the
plastic washer pair together in the mounting slot of the
anti-rotation arm. (See assembly diagram on page 4 for
full details)
11) Secure free end of the anti-rotation bracket to frame using bolt
or T-bolt provided. Use additional washers as needed to install
the bracket without a large deflection or bend.
12) Turn shaft by hand and verify the shaft turns freely and does
not produce excessive runout/wobble of the encoder
(<0.005" TIR [0.13mm], Total Indicator Reading).
13) Connect cable as shown in wiring diagram.
14) Apply power to the encoder.
