TR-1005R4
97
ERROR CODE : E82
DESCRIPTION : Wrong X-ray Tube selection.
ERROR TYPE : Indicative. Does not allow exposures.
APPLICABLE TO : All Generators with DRAC or L V-DRAC.
APPEARS WHEN : When changing Tube selection.
INFORMATION / SYMPTOM : Changing the tube selection, E82 is displayed.
POSIBLE CAUSES
No tube selected.
ACTIONS
1. Check that the Dip switch 3243--SW4--6 is in on position (tube selection inhibited).
2. Check delayed switch off.
ERROR CODE : E83
DESCRIPTION : Excessive current in DC Brake.
ERROR TYPE : Indicative. Does not allow exposures.
APPLICABLE TO : All Generators with DRAC or L V-DRAC.
APPEARS WHEN : During Anode braking in DC voltage.
INFORMATION / SYMPTOM : During braking operation of the anode with DC voltage, E83 is displayed.
POSIBLE CAUSES
Excessive current in main or auxiliary winding is detected.
ACTIONS
1. Check Switches configuration 324SW1 and 3243SW2 in CONTROL DRAC PCB. Refer to T ube
Family Selection in DRAC Documentation.
2. Check CR8, CR9, CR10 and CR11 in INTERFACE DRAC PCB. If any of them is found defective,
replace INTERFACE DRAC PCB.
3. Check Stator T ube Winding impedance (main or auxiliary) according to the X-ray Tube Stator
specifications.
4. Check correct Isolation between connections Main winding and auxiliary winding in TS2. If
winding in TS2 is not OK, replace TS2.
