What causes the FP-AI-110 module READY LED to flash upon power up?

[ElecTech]

The ready light flashes continuously on the FP-AI-110 module upon power up. The power light also seems to have a very short flash as well. The module part number is 184105C-01. The module has worked fine in the application for about two years. It had not been removed from the rail until this problem.

It is most likely that a component in the FP-AI-110 has failed (or been damaged) and the module is not successfully passing the self diagnostic program. To be absolutely certain that the module has failed, try inserting the FP-AI-110 into a different terminal base and make sure the flashing Power/Ready LED's still occur in other terminal bases. You will have to contact National Instruments to arrange an RMA of the module (for repair).
