10.2.2 Hysteresis function for OUT1
The hysteresis keeps the switching status of the output stable if the measured
value varies about the sensing range� The selected switch point [SP1] is the
set point� The reset point is automatically set above the selected switch point
[SP1] by the sensor� The nominal distance between set point and reset point is
the hysteresis, it is indicated in the data sheet� The hysteresis depends on the
reflectivity of the background�
Example Hno
1� For the output function [Hno] the output switches when the object approaches
and when the set point (A) is reached�
2� When the object is removed again, the output does not switch back before the
reset point (B) is exceeded�
The reset point (B) is above the set point (A)�
1
A =[SP1]
2
A = [SP1]
[SP1] =
switch point;
A = set point; B = reset point
If the output function [Hnc] has been selected, the set and reset points are
reversed� The output switches off when the object approaches� When the object is
removed again, the output switches on�
