32 C-Arm Control<br />

C-ARM MOTHERBOARD<br />

S/N 69-0001 through 69-2000 - Assy. #00-900588 - Sch. #00-875539<br />

S/N 69-2001 and higher - Assy. #00-900970 - Sch. #00-878396<br />

The C-Arm Motherboard is the backplane of the card rack as illustrated in<br />

Figures 10 and 11. It serves as a connecting point for the Technique Processor<br />

PCB, Analog Interface PCB and on newer models, the Image Function PCB.<br />

Also, there are many cables that connect to the back of the circuit board. There<br />

are two versions of the Motherboard as shown in Figures 15 and 16 .<br />

VR1 and VR2<br />

VR1 regulates the -15VDC from power supply PS1 down to -12VDC. VR2<br />

regulates the +15VDC down to +12VDC. These voltages are used in various<br />

places in the<br />

C-Arm.<br />

VR3<br />

Voltage regulator VR3 is only on the newer Motherboard (assy. #900970). It is<br />

not used at this time.
