Honeywell UDC3200 manual IN2 High, IN2 LOW, Bias IN2, Burnout Burnout Protection Sensor Break

Function Prompt	Selections or	Parameter
Lower Display	Range of Setting	Definition
	Upper Display
IN2 HIGH	–999. To 9999. Floating	INPUT 2 HIGH RANGE VALUE in engineering units
	(in engineering units)	is displayed for all inputs but can only be configured
		for linear or square root transmitter characterization
		See the example in IN1 HI.
IN2 LOW	–999. To 9999. Floating	INPUT 2 LOW RANGE VALUE in engineering units
	(in engineering units)	is displayed for all inputs but can only be configured
		for linear or square root transmitter characterization.
		See the example in IN1 HI
RATIO 2	–20.00 to 20.00	RATIO ON INPUT 2—Select the Ratio value you
	Floats to 3 decimal places	want on Input 1.
BIAS IN2	–999. to 9999.	BIAS ON INPUT 2 — Bias is used to compensate
	(in engineering units)	the input for drift of an input value due to
		deterioration of a sensor, or some other cause.
		Select the bias value you want on Input 1.
FILTER 2	0 to 120 seconds	FILTER FOR INPUT 2—A software digital filter is
	No filter = 0	provided for Input 1 to smooth the input signal. You
		can configure the first order lag time constant from 1
		to 120 seconds. If you do not want filtering, enter 0.
BURNOUT		BURNOUT PROTECTION (SENSOR BREAK)
		provides most input types with upscale or downscale
		protection if the input fails.
	NONE	NO BURNOUT—If Input 2 is being used in the
		Control Algorithm (such as the PV or RSP input
		parameter), then the pre-configured Failsafe output
		(selected in the CONTROL Set up Group) is applied
		when a failed input is detected (does not apply for an
		input out of range). Diagnostic message IN2 FAIL is
		intermittently flashed on the lower display.
	UP	UPSCALE BURNOUT will force the Input 2 signal to
		the full scale value when the sensor fails. Diagnostic
		message IN2 FAIL intermittently flashed on the lower
		display.
		The controller remains in Automatic control mode
		and adjusts the controller output signal in response
		to the full scale Input 2 signal developed by the
		Burnout circuitry.
	DOWN	DOWNSCALE BURNOUT will force the Input 2
		signal to the lower range value when the sensor
		fails. Diagnostic message IN2 FAIL intermittently
		flashed on the lower display.
		The controller remains in Automatic control mode
		and adjusts the controller output signal in response
		to the lower range Input 2 signal developed by the
		Burnout circuitry.
