kV exceeds permissible limit
Explanation: D916 (CPU) detects max. kV.
Action:
•
Check the test point "overvoltage error" TP - KVM on D916 (CPU), (high
= error) after exposure.
•
Check the cable connection between the single tank and D916.
•
Check the highest frequency of the main inverter, test point FC2 on
D916 (CPU).
•
Check the filament current.
Possible defects: D916, D907; single tank.
Tube current exceeds permissible limit
Explanation: D916 (CPU) detects I
D916, TP JIM).
Action:
•
Check test point TP - JIM on D916 (CPU), (high = error).
•
Check the filament current with preparation. Set potentiometer P5 (fila-
ment current during preparation).
Sporadic error message - check the highest frequency of the fila-
ment inverter.
Possible defects: D916, D907.
Short-circuit at the main inverter
Explanation: D916 (CPU) detects a main inverter short-circuit.
Action:
•
Check test point TP - SCM on D916 (CPU) after exposure, (high = er-
ror).
•
ERR 35 with exposures in all kV ranges indicates a probable single tank
defect.
•
Check the cable connections between D916 and D962 (X20).
•
Check the cable connections between D962 and the single tank (U - V).
•
Check C1.
