How to delete safety locked program from a 1756-L72S Processor

[Kenshinb2]

Hi there,

I'm doing some personal tests, I managed to get a 1756-L72S Allen Bradley processor, the problem is, it has a safety locked program. How can I delete this program? in the old models you simply unplugged the battery and the processor would loose its memory an then you could download a fresh program.

Thanks for the help.
