T roubleshooting
TR-1005R4
99
ERROR CODE : E86
DESCRIPTION : Incorrect T ube selection signal.
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, E86 is displayed.
POSIBLE CAUSES
No tube selected. X-Ray selection Signal is not correct on the Control DRAC PCB.
ACTIONS
1. Check that the Dip Switch 3243SW4--6 on the Control DRAC PCB is in ON position.
2. Check the connection of common wire.
3. Check the voltage at TP36 in Control DRAC Board.
ERROR CODE : E87
DESCRIPTION : Insuf ficient current in common wire during acceleration up to 3300 RPM.
ERROR TYPE : Indicative. Does not allow exposures.
APPLICABLE TO : All Generators with DRAC or L V-DRAC.
APPEARS WHEN : During acceleration of Anode at Low Speed.
INFORMATION / SYMPTOM : E87 is displayed and it is not possible to make Exposures.
POSIBLE CAUSES
Insuf ficient current in common wire 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 Stator T ube Winding impedance (main or auxiliary) according to the X-ray Tube Stator
specifications.
3. Check correct cable connection between Stator and TS2.
4. Check Winding impedance in transformers (main or auxiliary).
