For more information, see ERROR above.App Relay_OK DescriptionRELAY True A single fault (even a voter fault) degrades themode to dual. The relay provides a third channelfor shutdown so that if an output voter fails,there remain two independent channels (therelay and other ouput voter channel) that can deenergizethe output.RELAY False A voter fault degrades the mode to single.
