Mechanical Installation

A. General Overview

The following instructions are meant to assist in proper installation of

PulseIQ

Technology series HS35iQ hollowshaft encoders. The encoder

™

is a speed and position transducer that when mounted to a rotating

shaft, produces output pulses that are directly proportional to the shaft

speed and direction. The hollowshaft encoder is attached to the motor

shaft by using a clamp down collar. The HS35iQ can accommodate

several machine shaft diameters by selecting the appropriate bore size.

During installation, certain physical properties associated with the

mechanical coupling must be observed to ensure a long operation life

of the encoder. For proper Shaft slippage detection, standard Dynapar

tethering shall be used. Alternate tethering solutions may result in

improper detection.

B. Shaft Extension

Solid shaft preferred, keyway allowed; flatted shaft must not be used.

The minimum shaft engagement length that will allow support to

encoder housing is 1.25", Shaft engagement length of 1.60" (40.6

mm) or longer is recommended for reduced wobble. The longest shaft

length as measured from the mounting face that will allow installation

of the shaft cover is 2.60" (66 mm) maximum. Installations that employ

a press-fit or screwed-on stub shaft adapter should align the stub shaft

to 0.002" TIR or less with a dial indicator

C. Tether Point

For general industrial machinery and C-face motor installations, locate

the tether hole at the nominal bolt circle location. The tether holes are

slightly elongated, to allow for hole location tolerance and arcing of the

tether, if the hole location is not flush with the tether surface.

STEP 1:

Preparation and Recommended Tools

Disconnect power from equipment and encoder cable. Ensure that you

have the proper tools. Typical tools that may be needed depending on

the options chosen are:

• #2 Phillips Screwdriver

• 5/32" Hex Wrench(US)

• Caliper Gauge

• Dial Indicator Gauge

• 3/8", 1/2" or 1/4" T- handle Wrenches (tether options)

STEP 2:

Ensure that the mating shaft is within proper tolerances.

Recommended mating shaft diameter tolerances should be nominal

+0.0000"/-0.0005" [0.00 to -0.013 mm] and shaft runout TIR should

be under 0.002".

Clean the mating shaft of any burrs and check that mating shaft

engagement is at least 1.25" inside the encoder shaft. Using a dial

indicator gauge verify that the motor shaft Total Indicated Reading

(TIR) is less than 0.002" [ 0.05 mm].

STEP 3:

The encoder ships with an endcap to cover the back end of the

encoder body and, although optional, it is recommended for additional

environmental protection. To install, remove the factory installed three

screws at the back of the encoder, properly discard the removed back

plate and the three screws. Unpack the endcap, gasket and the three

screws from the factory supplied kit. Align the three holes and fasten

the gasket and end cap to the encoder body as shown.

Rotate the tether to the required orientation and tighten the tether arm

to the encoder body using the three screws provided. The hollowshaft

series encoder tethers can be rotated in 15 degree increments so that

connector or cable exit can be conveniently located.
