Component Checkout Procedures
This section lists procedures for troubleshooting the following
components:
• Power Supply Board
• Logic I/O Board
• Current and Voltage Amplifier Boards
• Battery Simulator
• Cooling Fans
Power Supply Checks
To verify proper operation of the power supply, perform the following
procedure:
1. Connect a multimeter to a ground point on the chassis, for example
Test Point 8.
2. Measure each of the following test points on the F6000 CPU circuit
board, located in slot 3 of the backplane:
Test Point #8: Ground (any point on the Instrument chassis can
be used as a reference).
Test Point #5: +5 V DC ±0.25 V
Test Point #7: +12 V DC ±0.25 V
Test Point #10: –12 V DC ±0.25 V
N
OTE
These test points are not on the edge of the printed circuit board. They
are located near the middle of the circuit board.
3. Replace the Power Supply Assembly circuit board (04S-0670-01) in
slot 11 if any of the test point voltages are not present. Refer to
”Circuit Board Replacement” on page 7-17.
Logic I/O Printed Circuit Board Checks
If the VFD displays a Logic Input or Logic Output error, perform the
following steps:
1. Verify proper operation of the power supply (refer above to ”Power
Supply Checks”).
2. If the power supply is operating correctly, replace the Logic I/O
circuit board (04S-0672-01) in slot 1. Refer to ”Circuit Board
Replacement” on page 7-17.
