3021	Bad unused port number
	Specify the input ports effective for the ground enabled input port
	(unused port). The port number must be 1 to 9.
3022	Cannot directly specify auto ground port channel
	Relays on the input ground port cannot be controlled directly when
	the ground mode is ON.
3023	Cannot directly specify unused port channel
	Relays on the ground enabled input port (unused port) cannot be
	controlled directly when the ground mode is ON.
3024	Cannot use same port for Couple and Auto Ground
	The couple mode and the ground mode cannot be used in parallel
