TR-1005R4
42
ERROR CODE : E11
DESCRIPTION : No voltage in the Capacitor Bank.
ERROR TYPE : Informative. “Prep” is not allowed.
APPLICABLE TO : All Generators
APPEARS WHEN : Only during initialization phase or when pressing “PREP”.
INFORMATION / SYMPTOM : It was not possible to perform “Prep” or “Exp”.
POSIBLE CAUSES
No voltage in the Capacitor Bank (5C1, 5C2, 5C3, 5C4) of the Generator Cabinet.
Defective Charge/Discharge Monitor Board.
Precharge K6 contactor located inside the Generator Cabinet is not energized.
Main line fuses F3 and/or F4 are blown off.
“--CHRG” signal of pin 7 on connector P1 on HT Controller Board is not present.
Exposition parameters selected above IGBT maximum current (only software versions before
V2.R06)
Cables disconnected accidentally or damaged connectors.
Test Switch SW1 of the Generator Cabinet is in “Test” position (only for Factory use). This is only
applicable to old Generators.
ACTIONS
A. IF LED DS1 IN CHARGE/DISCHARGE MONITOR LIGHTS
Check Capacitors V oltage,
• If it is OK, check that P1-7 in HT Controller is at logic level “0”. (0.75 V for Generators with 1
Charge/ Discharge Monitor Board and 1.5 V for Generators with 2 Charge/Discharge Monitor
Boards).
G If it is OK (logic level 0), replace HT Controller Board.
G If it is not OK, check links between P1-7 in HT Controller Board and P1-2 in
Charge/Discharge Monitor Board #1 and P1-1 in Charge/Discharge Monitor Board #1 and
P1-2 in Charge/Discharge Monitor Board #2,
-- If it is OK, replace defective Charge/Discharge Monitor Board.
-- If it is not OK, repair connection.
• If voltage in capacitors is not OK, check VAC in AC1, AC2 and AC3 at Input Rectifier Board (for
Battery Powered Generators check battery voltage).
G If VAC is not OK, verify input connections and input fuses.
G If VAC is OK, disconnect BUS+ and BUS-- at Input Rectifier Board and check VDC.
-- If VDC is not OK, replace defective component (CR1, CR2, CR3) at Input Rectifier
Board.
-- If VDC is OK, check and replace defective component at Generator Cabinet.
