Introduction

The

slipring is the main unit for the electrical and hydraulic connections between

the

hull and turret. The encoder, located on top of the slipring on the center of

the

turret floor, codes the movement of the slipring (in inches) and relays it to

the

azimuth indicator (in mils).

This task will contain an example of the replacement procedure for the encoder and

slipring assembly.

Maintenance of the Encoder and Slipring Assembly

This paragraph will cover the removal and installation of the encoder and slipring

assembly.
