text: <s>[INST] 1756-L83ES wipe or unlock safety Processor. I've got an upgrade on an existing CPU System problem is the customer has changed the safety Unlock password and doesn't know what it is, and I need to make edits in the safety software. So, the question I have is there a way to brute force the safety open or wipe the CPU so I can download the unlocked programme I have, I can't even Flash the CPU due to the safety being locked. Second to a new processor I've hit a brick wall. [/INST] Factory Reset. You can clear the program from memory on the 5570 controllers. On 5580 controllers, you can clear the program from memory and reset the controller to factory default settings.\n </s>
