Installing the Scanner

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.

Use a DVM to measure the outputs to the voltages listed in Table 2-4. Be sure 

to connect your ground probe to TPG1, TPG2, TPG3, or TPG4 on the Camera 

Controller Board.

There are no adjustments to the +12V, 200W boost power supply. If its output is 

not +12.5V to 16V, replace the supply.

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.
