INSTALLATION

Refer to the back page of these instructions for outline and mounting

dimensions. Also available: EU (European Union) Installation Sheet and

Basket Mount Installation Sheet.

Disconnect power from equipment and encoder cable.

Use caliper gauge to verify motor shaft is proper diameter and

within allowable tolerances: +0.000", -0.0005" [+0.00,

-0.013mm].

Clean machine shaft of any dirt and remove any burrs.

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 and insert shaft sizing insert into

encoder. DO NOT FORCE.The insert has a retaining flange

and is larger at one end than the other.

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) Apply thread locker to screw on clamping collar. Note: models

shipped

since 2015 have thread locker preapplied to clamping

screws. Tighten each screw to 18-20 in-lb [2.0-2.3 Nm]. DO NOT

USE A STANDARD RIGHT ANGLE WRENCH.Use only a T-handle hex

wrench or torque wrench with hex bit.

9) Secure free end of anti-rotation bracket to frame. Use in sul at ing

hardware as shown (supplied with Avtron anti-rotation kit). Use

additional washers as needed to install the bracket without a

large deflection or bend. For 8.5" C-Face, install 1/2"-13 to 3/8"-

16 reducer with 3/8"-16 threaded stud (supplied) to secure anti-

rotation bracket using insulating hardware as shown.

10) Turn shaft by hand and verify the shaft turns freely and does

not produce excessive runout/wobble of the encoder:

<0.005" [0.13mm] TIR (Total Indicator Reading). Additional

instructions under "Adjusting the Encoder to Eliminate Excess

Runout/Wobble" are provided if needed.

11) Connect cable as shown in wiring diagram.

12) Apply power (5-28VDC) to the encoder.

13) Rotate the shaft by hand, or using jog mode of the speed

controller and verify proper direction.

14) Optional: Install Protective Basket using either T-bolts (Fan

Cover) or bolt to 4.5" C-Face (bolts provided). For 8.5" C-Face

use adapter clips supplied. Be certain that the Protective

Basket does not touch or interfere with the anti-rotation arm.

To mount the basket on an 8.5" C-face, thread the 1/2"-13

bolts into the motor face, through each clip (provided with

options "F" and "U") but do not tighten fully. Pivot the basket

over the encoder, and pivot each clip over each respective

basket bolt hole. DO NOT FORCE. Tighten each bolt to

secure the basket and clip.

Adjusting the Encoder to Eliminate Excess Runout/Wobble:

In a typical installation, a housing movement of 0.005" TIR or less (as

measured at the outside diameter of the main encoder body) will not

have an adverse effect. If excessive housing movement is detected in

the installation:

Check the shaft the HS35A is mounted on for excessive

shaft runout using a dial gauge. NEMA MG1 calls for 0.002"

TIR or less.

Verify that the mounting shaft meets minimum and maximum

diameter tolerances.

Maximize the shaft insertion into the encoder (retaining the

minimum of 1/8" between mounting face and encoder)

Loosen the clamping collar and rotate the motor shaft 180°

within the encoder hollow shaft sleeve. Retighten the

clamping collar.

Loosen the clamping collar; move the split in the clamping

collar over a solid portion of the encoder shaft, retighten the

clamping collar.

If excessive housing movement still exists after the above steps, the

shaft or the encoder may be damaged and should be checked by the

manufacturer.

Shaft Sizes:

HS35M: 1/2"*, 5/8"*, 3/4"*, 7/8"*, 1"*, 1 1/8", 12mm*, 15mm*,

16mm*, 20mm*, 25mm, 30mm

NOTE:

HS35A units <1" bore utilize shaft insulating resin insert;

models may be resized as needed by interchanging or

removing inserts. Consult factory for other shaft

sizes not shown.

Shaft Engagement:

HS35A: Shaft insertion/engagement should be 1.25" to 2.25" [32mm

to 57mm] with a minimum of 0.125" [3mm] between encoder and

mounting surface. Minimum insertion/engagement is 1.75" [44mm]

for models using a sizing insert. If greater shaft insertion is required,

remove outboard shaft cover and mount the encoder as a through-

shaft unit.

For shaft lengths greater than the maximum engagement allowed, end

of shaft mounting may still be employed by using a spacer between

the mounting surface and anti-rotation bracket.

CAUTION

When inserting shafts to a depth over 2.25" [57mm], be

sure to remove the shaft cover to prevent cover contact

with the rotating shaft.

WIRING INSTRUCTIONS

CAUTION

Be sure to remove power before wiring the HS35A

Encoder. Be sure to ground the cable shield(s): It can be

connected to case ground at the encoder, or grounded at

the receiving device, but should not be grounded on both

ends. If necessary, case ground can also be provided

through a separate wire. Be certain not to ground the

case ground wire if the encoder is already grounded by

mechanical mounting. (The standard antirotation arm

kits provide insulating washers)
