We have a Voest Alpine Governor on a 25 mw hydro with a MIPREG controller that is giving us a EEPROM error and tripping the system relay. The manual only tells us that the eeproms and/or nvrams are defective. we have changed the motherboard with our only spare and are still getting the same results. We have monitored every possible input with a Fluke GL900 recorder and have found no disruptions prior to the trip time.
