BRNOUT		BURNOUT PROTECTION (INPUT FAILURE) provides most input
		types with upscale or downscale protection if the input fails. Note
		that if the input fails, error message “INP FL” will be on the lower
		display.
			ATTENTION	Refer to Subsection 4.5 for information about the
		interaction of the value of this parameter and the setting of switch 2
		on SW6.
	NONE [factory setting]	NO BURNOUT—Failsafe output applied for failed input.
	UP	UPSCALE BURNOUT will make the indicated PV signal go to
		overrange value when input fails. Control algorithm will use
		overrange value when calculating output.
	DOWN	DOWNSCALE BURNOUT will make the indicated PV signal go to
		underrange value when input fails. Control algorithm will use
		underrange value when calculating output.

NOTE: For recorders with the FM Limit Approved Option the INPUT configuration does not provide a burnout selection. However, if a HI limit is configured and the input opens, the input reading will go Upscale and the lower display will alternate between: INP#, Limit, and INP FL.

If a LO limit is configured and the input opens, the input reading will go down scale and the lower display will alternate between: INP#, Limit, and INP FL.
