Hi John the S5-100U CPU has an EPROM in it which requires half an hour under a UV lamp to be erased and we can probably exclude it being accidentally erased (or erased at all for that matter). Best I can offer to help for now are a few pointers and questions as followed: 1.) Link to the S5-100U manual Chapter 4.3 describes the steps for automatic and manual loading of the program If neither works, please get full description on LED status for each step 2.) Is there a backup battery in the CPU? If yes, power the CPU off, take it out and power back up (with EPROM in it) 3.) You say that "They replaced the CPU card". Does that mean they replaced the CPU OR they replaced the EPROM? 4.) Do they have the means to go online in the the CPU? (e.g .do they have Siemens Step 5 or ibhsoftec S5 for Windows and the AS511 TTY programming cable?) 5.) Do they have the means to erase and burn EPROM's? |

Thank you so very much Fritz for guiding our folks to solve the problem with the YWAM Liberty's engine alarm panel. Your troubleshooting and fault isolation efforts solved the problem in loading the program from the eeprom. We weren't easy to work with, and you hung in there! We're deeply grateful as there was absolutely no way our on-board team could have solved this without you. God bless you and the folks at ISS. John Cobb YWAM Liberty Project Manager
