3.2.2 PROGRAMMING OF ROTOR ACCELERATION TIME, RAD FILAMENT SETTING TIME,
FLUORO ROTOR AND FILAMENT HOLD-OVER TIME
Rotor Acceleration Time is determined by the X-ray Tube and
Rotor characteristics and it must be considered when the
Generator is about to be configured. X-ray Tube could be
permanently damaged unless the required RPM are reached
before an exposure. (Refer to technical information of the
X-ray Tube).
Dip Switch 3000SW2 on the HT Controller Board is used to program:
• Rotor Acceleration Time. That depends on stator voltage, stator
frequency, stator type, quality of X-ray tube bearings, and X-ray tube
anode size. A reed tachometer or a stroboscope can be used to
determine the anode RPM. Be sure that the Rotor Acceleration Times
meet all requirements for anticipated customer applications.
This value is programmable from 0.8 to 2.7 seconds. After this time the
Rotor is hold running in maintaining mode as long as “Prep”isactive.
• Rad Filament Setting Time. This parameter has the same configuration
value than the Rotor Acceleration Time. Sometimes, if it is required to
increase the Rad Filament Setting Time to the next v alue, configure the
respective switches again. This adjustment avoids Error-12.
• Fluoro Rotor Hold-over Time and Fluoro Filament Hold-over Time.This
value can be programmed to run for 1 minute or not at all, after releasing
the Fluoro Pedal.
The Rotor Acceleration Time and Rad Filament Setting Time is
factory set to 1.8 seconds. The Fluoro R otor Hold-over Time and
Fluoro Filament Hold-over Time is factory set to 1 minute. Maintain
this value when it is unknown or not provided with the X-ray Tube
documentation.
1. Turn the Generator OFF and note current settings of the dip switch
3000SW2 on the HT Controller Board.
Configuration of these times are only allowed when dip switch
3000SW2-1 is in “Closed” (On) position after power the Generator
OFF and back ON again.
