I have a control panel using an Eaton ELC controller for operation and for alarm outputs. The outputs OPEN on a fault. Recently, there have been some power issues at this location, and we've gotten multiple alarms. I'm thinking the power outage (before a generator kicks in) is opening these outputs, but that seems like a stupid design. Is this at all common?
The Eaton manual says the controller will continue operating with a power loss of 5-10ms, but that's obviously way to quick for a utility-out, generator start, transfer situation. I've added a delay between the output going to alarm and when somebody gets notified, but the whole opening on fault seems crazy except for very certain situations.
