Logic Voltage Check-out Procedure{ XE "Adjustment:Multivolt logic
power supplies" }
The outputs of the power supplies { XE "Power supplies, multivolt logic:Adjustment" } { XE
"Power supplies, multivolt logic:Voltage checkout procedure" }{ XE "Logic power supplies" \t
"See power supplies, multivolt logic" }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.
1. Turn on the scanner power switch.
2. Use a DVM to measure { XE "Measurement:Multivolt logic power supply" }the outputs
to the voltages { XE "Checkout:Logic voltages" }{ XE "Logic voltages" }{ XE
"Voltage:Power supply, multivolt logic" }listed in Table 2-4. Be sure to connect your
ground probe to TPG1, TPG2, TPG3, or TPG4 on the Camera Controller board.
