Remove three screws, lockwashers, and washers attaching the adapter to

the slipring. Then remove the adapter from the slipring. Discard the lockwashers.

Procedural Steps for Installation of the Encoder and Slipring Assembly.

Three final procedures are needed to complete the installation of the encoder and

slipring assembly.

These procedures are described in subparagraphs 2c(2) through

2c(4) below.

(1)

Installation of the Encoder and Slipring Assembly.

Step 1.

Install adapter, three washers, new lockwashers, and screws on the

slipring.

Step 2.

Install the coupling on the encoder shaft with a setscrew aligned with

the flat surface on the encoder shaft. Adjust the coupling onto the encoder shaft

so that .138 to .198 inch is between the coupling and the encoder.

Tighten two

setscrews on the top half of the coupling.

NOTE

The setscrew aligned with the flat surface on the encoder

shaft is the same setscrew that is aligned with flat

surface of the slipring shaft.

Step 3.

Set the encoder to mechanical zero setting by turning the adapter until

the flat surface of the slipring shaft can be seen in the nipple hole of the

adapter. Align the setscrew on the coupling with the flat surface of the slipring

shaft, then place the encoder on the adapter.

NOTE

Slipring, adapter, and encoder shaft must stay in the same

position set in step 3 or mechanical zero will be lost.

Step 4.

Locate two setscrews on the coupling through the plug hole on the

adapter.

Tighten a setscrew. Rotate the adapter slowly until the
