I have a 4005 panel that occasionally would restart but got stuck at self testing. I need to do a power reset to revive it, then it will be good for days if not weeks before got stuck again. Any ideas?
Do you have level 4 access to the panel, it could be something that is improperly programmed in the panel.
Yes I do, where should I look for the setting?
Another question is that occasionally I get a trouble that says “left backplane overcurrent”, what does this mean?
