GE Mark VIeS - I;O Pack Internal Reference Voltage out of Limits; I;O Pack Internal Null Voltage out of Limits; Logic Signal Voting Mismatch

101
Description I/O pack internal reference voltage out of limits
Possible Cause The calibration reference voltage for the analog inputs is more than ±5% from the expected value,
indicating a hardware failure.
Solution
• Check the I/O pack ground quality through mounting bolts.
• Cycle power to the I/O pack.
• Replace the I/O pack.
102
Description I/O pack internal null voltage out of limits
Possible Cause The calibration Null voltage for the analog inputs is more than ±5% from the expected value, indicating a
hardware failure.
Solution
• Check the I/O pack ground quality through mounting bolts.
• Cycle power to the I/O pack.
• Replace the I/O pack.
