Technical Manual
Generator processor (105-10-03)
This circuit board is located beside the generator in the horizontal section of the rotating part.
This is the circuit board that is nearer to the cassette end of the rotating part. Its function is to
control the generator and to operate three stepper motors, the rotating part rotation motor, the
film cassette transportation motor and the tube head primary aperture motor. It also operates the
tube head cooling fan and the cephalostatic solenoids when applicable.
When this circuit board is replaced, the new one must be adapted to the system. This circuit
board contains information about the primary aperture positions as well as the X-ray tube type
and filament characteristics. Therefore the primary apertures must be aligned and the tube type
must be programmed, after which the system must be allowed to learn the filament parameters.
F1 protects other circuits than the stepper motor drivers on this board and is rated 1AT
Cassette limits (105-10-04)
This circuit board is located in the cassette end of the rotating part. It’s function is to detect the
end limits of the cassette motor movements and pass the information to the generator processor
through a 20-pole flat cable.
When replaced, the four Hall-detector magnet adjustments are to be checked.
Low voltage power supply (105-10-05)
This circuit board is located in the upper fixed part. It supplies power to all of the electronics
(including lamps) in the equipment and has the main secondary fuse on it. If the equipment is
completely dead and the fuses near the mains switch are OK this is the place to look at.
When replaced, the operating voltage jumper and the primary fuse must be checked to match the
ones of the faulty circuit board.
Voltage selection: The jumper can be installed into four positions to adjust the operating voltage
range (100, 110, 220, 240 V) The equipment operates at this voltage ± 10% with full load. Be
sure that the selected voltage range is similarly selected on the TUBE POWER GENERATOR
circuit board.
F1 Frankfurt positioning light fuse 2.5 AT
F2 Mains primary fuse (500 mAT for 220 V and 240 V; 1 AT for 100 V and 110 V)
F3 Main secondary fuse 4 AF
F4 Layer positioning light fuse 2.5 AT
F5 Sagittal positioning light 2.5 AT
CAUTION Make sure that the power is switched off before handling the board to avoid electrical
shock and unnecessarily blown fuses if some live parts touch the frame.
Keyboard processor (105-10-06)
This circuit board is located in the lower fixed part. It is the master microprocessor that controls
everything in the equipment. It operates three motors, the up/down motor, the layer adjust motor
and the patient temple rest motor. It also controls the operation of the generator processor and
gives the operation commands to it via one serial communications cable. It operates the two
relays on the low voltage power supply that give power to the generator and to the lamps. The
keyboard and display are also controlled by this processor.
When this circuit board is replaced, the new one must be adapted to the system. This circuit
board contains information about the warning signal pitch, up/down motor speed settings, layer
adjust motor location and zero point, operational parameters (kV, mA, sectors, layer forms etc.),
the exposure counters and the time. Also the error history and previous technical factors memo-
ries go along with this circuit board. There are two things that MUST be done before use when
this board is replaced:
In the service mode pass twice the layer motor reference sensor to find the place.
Tell the system whether it is a panoramic or a cephalostatic one.
F1 protects other circuits than the motor drivers on this board and is rated 1AT
