SYSTEM DIAGNOSTICS
Store Configuration {1}		Setting this parameter to “Enable” will cause the current		Store Cfg	m+
[SYSTEM/DIAG]		rectifier configuration to be stored (the display toggles back		Disable
		to “Disable” after entry).
Lamp Test {1}		Setting Lamp Test to “ON” will turn on the “MAJOR”,		Lamp Test	m+
[SYSTEM/DIAG]		“MINOR”, “NORMAL”, “MAJ”, and “MIN” LEDs on the		OFF
		control unit front panel.
Test Relay Enable {1}		This parameter must be set to “Enable” to permit the eight		Test Relay En m+
[SYSTEM/DIAG]		output relays to be manually tested; otherwise, the state of the		Disable
		relays will be per system conditions.
