1B.5.4 Console CPU Board / Console Board
For 23 X 56 (cm) consoles: This symbol is printed on the console CPU board near U32.
HIGH VOLTAGE HAZARD: Approximately 400 VAC is present on this board in the area of U32
and J10. This voltage is used to light the backlight for the LCD display assembly in the
console.
For 31 X 42 (cm) consoles: This symbol is printed on the console board near U40.
HIGH VOLTAGE HAZARD IF U40 IS FITTED: U40 is a high voltage source for the fluorescent
backlight on the LCD display. Approximately 400 VAC is present on this board in the area of
U40 and J10 if U40 is fitted. On LED backlight versions of the LCD display, high voltage
source U40 is not fitted and no high voltage is present in this area.
1B.5.5 Generator Interface Board
This symbol is printed on the generator interface board in the high volage (mains) area.
HIGH VOLTAGE HAZARD: Components within the dashed line on the board have high
voltage applied at all times that the main disconnect is switched ON. These components are
live EVEN WITH THE CONSOLE SWITCHED OFF.
This symbol is printed on the generator interface board near fuses F1 to F6.
FUSE RATINGS:
F1:
F2, F5: 2.5A 250V slow blow
F3, F4: 5A 250V slow blow
F6:
1B.5.6 Room Interface Board
This symbol is printed on the room interface board near the 110/220 VAC terminal blocks.
HIGH VOLTAGE HAZARD: 110/220 VAC may be present on this board at all times that the AC
mains to the generator is switched on.
1B.5.7 AEC Board
This symbol is printed on some versions of AEC board with a high voltage power supply for a
PMT or ion chamber.
HIGH VOLTAGE HAZARD: Depending on the AEC board type, up to approximately 1000 VDC
may be present on the AEC board at all times that the generator is switched on.
1B.5.8 Power Input Board
Power input boards for single phase 240 VAC generators are fitted with several high power
resistors that operate at temperatures sufficient to cause skin burn. Ensure that these resistors
have cooled sufficiently after the power has been switched off before servicing.
