Description All fuses blown or no terminal board excitation
Possible Cause If fuse sensing indicates an open fuse, this may be due to loss of input power to the terminal board.
Without power to the fuses, the sensing may indicate a false open-fuse condition.
Solution
• Confirm the correct input power to the terminal board.
• Check the I/O pack connector alignment and seating.
• Check the I/O pack configuration.
• Check all fuses.
• Replace the I/O pack.
• Replace the terminal board.
