OK. While pg interface is not connection to others device "IF faillure" led still led red light up.
I think, propalby if cpu unit 928 is ready(green led still light up). CPU unit have mabye internal problem with controller? Because i have problem with controller. On the display is "controller failure ". Where is problem? coordinator(if failure) or controller(green led run light up)? |
