Input combination of signals generated from external tomographic accessory is wrong:
Generator uses following signal to switch to Tomography scan mode:
TOMO ANGLE (ONLY ONE between possible selectable angles in NON coded mode)
TOMO SPEED ((ONLY ONE between possible selectable speeds in NON coded mode)
TOMO ON to activate Tomography Scan mode
In case one ANGLE e SPEED digit is missing, or more than one (NON coded mode) ANGLE or SPEED are selected WHEN TOMO ON signal is switched ON this FAULT is produced
Check the input LED against previous description when this error appears.
Verify the cable connection between generator and tomographic accessory
Verify the signal generation on tomographic accessory
