GV60 TROUBLESHOOTING MANUAL READING ELECTRICAL SCHEMATICSVERSION 1.0 2018-01-01 PAGE 4.4.1SECTION 4.4: READING ELECTRICAL SCHEMATICSThis section contains electrical schematics and logic diagrams for the transmitter. Block diagrams,simplified electrical schematics, and logic diagrams may be included. Refer to Table 4.4.1 on page 4.4.5for an itemized listing.Component ValuesUnless otherwise specified on the logic or schematic diagram, the following defaults apply:Graphic and Logic SymbolsThe graphic symbols used on electrical schematics are in accordance with American National StandardANSI Y32.2-1975 - Graphic Symbols for Electrical and Electronic Diagrams.The logic symbols used on electrical schematics and logic diagrams are in accordance with AmericanNational Standard ANSI Y32.14-1975 - Graphic Symbols for Logic Diagrams.Reference DesignationsReferenced designations were assigned in accordance with American Society of Mechanical EngineersASME Y14.44-2008 - Reference Designations for Electrical and Electronic Parts and Equipment.Each electrical symbol is identified with its basic reference designation. To obtain the full referencedesignation for a specific part, prefix this basic identifier with the reference designation assigned to allhigher assemblies. For example, the complete designation for a resistor (R1) on a printed wiring board(A1), that is part of a larger board (A2), would be A2A1R1.10524V Unidentified transient suppressors are part number 0603E SDA-TR1 (Nautel Part # QR70)Unidentified diodes are part number BAS21HT1 (Nautel Part # QDRS01)Resistor values are shown in ohms (e.g. 10 ohms; K = 1,000 and M = 1,000,000)Resistor power ratings are not shown when less than 0.5 WCapacitor values are shown in microfarads (uF) (e.g. 5 uF)
