Hi All - I have a customer with an ECS V8, that has had a couple of "Major Alarm 5" incidents. The ECS just reboots and seems to be okay for another few months. Is this just a PITA kind of alarm, or should I be thinking about replacing the CCU? The manual says it is a "Phase Reset Error". I have NO idea what that might mean. Is there something I can do to help avoid these alarms? Any input is appreciated!
