Relay 1	On / Off output relay turns On when the input is greater than the relay high and low ranges
Relay 2	and turns off when the input is less than the relay high and low ranges. This allows an on /
Relay 3	off control action with an adjustable dead band. The On state is controlled by a cycle time
Relay 4	and on duration parameters such to achieve a selectable output proportion. An invert
ON/OFF	parameter is available to allow inverse action such that the relay will cycle ON when below
	the low range limit.

	High Range	-99999 to 99999	The high range is the PV based engineering unit
		default = 100.00	value configured as the value that will produce a
			100 percent (Maximum Frequency) duty cycle.
	Low Range	-99999 to 99999	The low range is the PV based engineering unit
		default = 0.00	value configured as the value that will produce a
			0 percent (always inactive) duty cycle.
	Invert	Enable	Inverts the proportional range or input state of
		Disable (default)	the applied digital or analog input such that
			inverse relay operation is achieved.
	Cycle Time	0 to 999	Cycle time is that time period, in seconds,
		default = 10	between relay activations.
	On Time	0,0 to 999	Sets the pulse duration. This value should be
		default = 5	less than the cycle time for proper operation.
			Typically this value is used to control the pulse
			duration for the finial output control element.
