THIN-LINE III

directly replaces THIN-LINE II

THIN-LINE

models. THIN-LINE III models have Rev

Code BA or later. Special option 4xx selects an alternate

PPR code defini tion. Example: PPR Code 0, Special

Option Code 401 = 1270 PPR (Left), No Right Output.

INSTALLATION

Installation and removal videos for the AV56A/67/85/115 are available

on Avtron's web site. Refer to the back page of these instructions for

outline and mounting dimensions. The motor must comply with 1998

NEMA MG 1, section 4, for tolerances on diameters and runout for

shafts and accessory faces. Axial float or endplay must be less than

±0.050".

In preparation for installing the Model AV56A encoder, it is first

necessary to clean both the accessory motor shaft and the mounting

face. These surfaces must be inspected and any paint, burrs, or other

surface imperfections removed.

Installation procedures 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.

ROTOR INSTALLATION

The motor shaft must project at least 0.63" from the motor face. For

set screw rotors only: Apply anti-seize compound to the motor shaft.

For all rotors: Slide the rotor onto the shaft with the marking "Motor

side" facing in, (toward the motor face). The rotor centerline must

match the sensor centerline. To accomplish this, use the rotor locating

gauge (A28503) and slide the rotor onto the shaft until it is in the

proper position as shown in Figure 1. If a guage is not available, use

the stator housing alignment grooves as shown in Figure 3.

STANDARD CAM SCREW ROTOR INSTALLATION

Turn the cam screws of the rotor in the directions shown on the rotor

to engage the cams. Tighten to 50-60 in-lb [5.6 - 6.8 N-m] (See Figure

2) using the 3mm hex wrench. Total cam screw rotation will be less

than one turn.

CAUTION

Do not adjust the cam screws before motor shaft

mounting; bottoming out the screws, or backing them

out excessively, can lead to insufficient shaft holding

force. Thread locker is preapplied on the cam screws.

LARGE BORE SET SCREW ROTOR INSTALLATION

Apply thread lock er to the rotor set screw holes, preferably from the

inside of the rotor bore before mounting. Tighten the rotor set screws

to 15 in-lb [2 N-m] using the 2mm T-handle hex wrench.

CAUTION

Use only a T-handle or torque hex wrench to tighten

set screws; using a right angle wrench will not provide

enough holding force, and the rotor may slip.

STATOR HOUSING INSTALLATION

The stator housing is attached to the motor using four socket head cap

screws (4) 3/8"-16, locating on a 5.88" bolt circle. Longer bolts (not

included), are required for sandwich installation between a motor and

a brake. Install the four mounting bolts using thread locker and torque

to approximately 20-30 ft lbs [27 to 40 N-m] using the 5/16" T-handle

hex wrench.
