B. IF LED DS1 DOES NOT LIGHT AND IT IS NOT A BATTERY POWERED GENERATOR.
• Check input VAC in 6LF1,
G If VAC is OK, replace a defective component at Input Rectifier Board (CR2, CR3 or CR1).
G If VAC in 6LF1 is not OK, check that contactor 6K5 is ON.
-- If 6K5 is ON, check VAC in T1,T2 and T3 (in 6K5).
-- If voltage is OK, replace defective 6R1.
-- If voltage is not OK, replace the defective fuse (F3, F4 or F5).
• If Contactor 6K5 is not ON, check if signal +24VPSU is OK.
G If it is not OK, check and/or replace 3F6 and 6T2.
G If +24VPSU is OK, check that signal --LINE CONT is at 0 VDC,
-- if --LINE CONT is OK, replace 6K5.
-- If --LINE CONT is not OK, check continuity in J3-10 at A TP Console Board.
-- If --LINE CONT is OK at ATP Console Board, repair connection between J3-10
and “A” in 6K5.
-- If --LINE CONT is not OK at ATP Console Board, replace ATP Console Board.
C. IF LED DS1 LIGHTS AND IT IS A BATTERY POWERED GENERATOR.
Check Contactor 6K5,
• If 6K5 is ON, check output voltage of 6K5.
G If 6K5 output voltage is OK, replace defective 6R1.
G If 6K5 output voltage is not OK, check and replace 6F1, 6J1 and Andersen connectors.
• If 6K5 is not ON, check if signal +24VPSU is OK.
G If it is not OK, check and/or replace 3F6 and 6T2.
G If +24VPSU is OK, check that signal --LINE CONT is at 0 VDC in J3-10 at ATP Console
Board,
-- if --LINE CONT is OK, replace 6K5.
-- If --LINE CONT is not OK, check continuity in J3-10 at A TP Console Board.
-- If --LINE CONT is OK at ATP Console Board, repair connection between J3-10
and “A” in 6K5.
-- If --LINE CONT is not OK at ATP Console Board, replace ATP Console Board.
D. IF LED DS1 DOES NOT LIGHT AND IT IS A BATTERY POWERED GENERATOR.
Check Contactor 6K5,
• If 6K5 is ON, check output voltage of 6K5.
G If 6K5 output voltage is OK, replace defective 6R1.
G If 6K5 output voltage is not OK, check and replace 6F1, 6J1 and Andersen connectors.
• If 6K5 is not ON, check if signal +24VPSU is OK.
G If it is not OK, check and/or replace 3F6 and 6T2.
G If +24VPSU is OK, check that signal --LINE CONT is at 0 VDC in J3-10 at ATP Console
Board,
-- If --LINE CONT is OK at A TP Console Board, repair connection between J3-10 and
“A” in 6K5.
-- If --LINE CONT is not OK at ATP Console Board, replace ATP Console Board.
