Illustration:

Configuration from the front panel of the smart relay, of the hysteresis-type comparator with constant reference value:

1	A 1 A N A L O G 7
2	x 1 - H ≤ ξ 2 ≤ x 1 + H
	R = 4 . 0	x 1 = R
3	H = 1 . 5	x 2 = I e
	-	+
		Menu / OK
	4	5

In this case: The comparison condition is verified when the power to the input terminal Ie is between 2.5 Vand 5.5 V.

Configuration of a single comparator from the front panel:

1	A 1 A N A L O G		5
2	x 1 ≤ x 2	x 1 = I d
3		x 2 = I e
	6	+
			Menu / OK
		4

(If neither x1 nor x2 are not set to R, parameter R does not appear.

Description:

Number	Parameter	Description
1	Type of comparison	The number that follows ANALOG corresponds

2	Comparison formula	Formula used for comparison.
3	Parameter lock	Locking prevents locked parameters from
		being modified from the front panel of the
		smart relay using the PARAMETERS menu.
