Installation Manual

1 INTRODUCTION

This document describes the installation of the Robertson RGC12 Gyro Compass.

The compass consists of the Master Compass with Sensitive Element and Control Box.

The gyrocompass RGC12 is a system to detect and display true heading necessary for navigation and output data to external equipment. It has been designed for medium and large vessels and provides high accuracy and reliability on the basis of the TG-5000 series gyrocompass which has been installed on more than 5000 vessels.

The Control Box contains all interfaces to external equipment, as well as connection to the Master Compass. Power for the gyro system is also terminated in the unit.

Note ! The guidelines for installation presented here must be regarded as a base for detailed plans prepared by the installation shipyard. These plans must include drawings, instructions and procedures specific to the ship in which the equipment is to be installed. These drawings must be approved by the local maritime classification society.

Simrad Robertson AS accepts no responsibility for any damage or injury to the system, ship or personnel caused by drawings, instructions or procedures not prepared by Simrad Robertson AS.
