5 AC ( ) / AC ( ) Section 1 GENERAL INFORMATION 1.1 Introduction The following system manual describes the RMI-Converter AC 3503-( ) /AC 3504-( ). The manual DV contains the following section : Section DV General Information X 2 Installation X 3 Operation 4 Theory of Operation X 5 Maintenance and Repair X 6 Illustrated Parts List X 7 Modification and Changes X 8 Circuit Diagrams X 1.2 Purpose of equipment The equipment has been designed to meet the requirements of JTSO-2C41d. For operational requirements under environmental conditions, EUROCAE/RTCA ED-14C/DO-160-C has been taken as a standard. In the certified Environmental Categories, there are practically no restrictions for use of the RMI converters in rigid airframe attachment. In demonstration tests, all systems were shown to be functional at operating pressures equivalent to altitudes of up to feet. DV Issue 01/93 Page 1-1

11 AC ( ) / AC ( ) Section 2 Installation 2.1 General Installation of the RMI-Converter AC 3503/AC 3504 will depend on the aircraft type and equipment fitted, and thus only general instructions can be provided in this section. Before installing the RMI-Converter in an aircraft, examine the equipment for evidence of damage in transit. 2.2 Preinstallation Check Unpack the equipment and inspect all assemblies for evidence of damage Operational Check A functional check prior to installation is only reasonable when all system components (receiver, Converter and indicator unit, and antenna, etc.) are installed. Therefore, such a functional check is described in the System Manual DV Mechanical Installation RMI-Converter AC ( ), AC ( ) The RMI-Converter is intended for installation in the avionics compartment of the aircraft. The dimensions are shown in Fig Installation Wiring The interwiring diagrams as well as informations of cable are described in the System Manual DV Post-installation Check A functional check after installation is only reasonable for all system components (receiver, converter and indicator RMI-converter, and antenna, etc.) together. Therefore, such a functional check is described in the System Manual DV DV Issue 01/93 Page 2-1
