Logic Voltage Check-out Procedure

The outputs of the power supplies are read at their most critical point-the input to
the Camera Controller Board, the Solenoid Clutch Activation Board, and the Top
LED Mother Board.
Turn on the scanner power switch.
1.
Use a DVM to measure the outputs to the voltages listed in Table 2-4. Be sure
2.
to connect your ground probe to TPG1, TPG2, TPG3, or TPG4 on the Camera
Controller Board.

+12V Boost Power Supply

There are no adjustments to the +12V, 200W boost power supply. If its output is
not +12.5V to 16V, replace the supply.

Location of the Power Supplies

Figure 2-1 and Figure 2-2 illustrate the location of the power supplies and the
location of the adjustment potentiometers. The power supplies that may require
checkout and periodic adjustments are:
•
+12V, 250W, Solenoid and DC Motors Power Supply (adjusted to +12.5V)
•
+5V LED Power Supply
•
+5V and ±15V Logic Power Supply
The Logic Power Supply is labeled ±12V, but it should be adjusted to ±15V.
