TM 9--2350--292--20--1ENHANCED DIAGNOSTICS OVERVIEW AND DIAGRAMS0060 00THIS WORK PACKAGE COVERS:Enhanced diagnostics Overview And DiagramsThe Enhanced Diagnostics System (EDS) provides a tool to permit troubleshooting of hydraulic malfunctions whilereducing the need to install gauges which reduces the possibility of introducing contaminants into the system. TheEDS consists of 37 pressure sensors, a remote terminal (RT) unit and cabling to connect the sensors to the RTunit. The EDS is permanently installed in the vehicle and does not interfere with the normal operation of the ve-hicle’s hydraulic system. The RT unit is connected to the Soldier Portable On--system Repair Tool (SPORT) via a1553 bus cable and the SPORT’s 1553 bus card. The SPORT runs the EDS software program which allows amaintainer to use the EDS to read hydraulic pressures in realtime while conducting hydraulic troubleshooting.The 37 pressure sensors are divided into 32 pressure transducers and 5 pressure switches. The sensors areinstalled in the hydraulic system in the same locations that the hydraulic troubleshooting called for gauges to beinstalled.The RT unit is an electronic enclosure that contains a printed circuit card, a power module, POWER toggle switch,a POWER indicator lamp and connector jacks to connect the cables from the sensors. The RT unit also stores thesensor calibration offset data.When the EDS software program is running the maintainer can view selftest results by clicking on TEST in themenu then on Self Test in the drop down menu.The following functional diagram provides information about cabling and sensor location.0060 00--1/2 blank
