IFM LR8000 - 10�6�2 Set the Switching Limits (Hysteresis Function); 10�6�3 Set the Switching Limits (Window Function); 10�6�4 Setting of the Switch-Off Delay; 10�6�5 Response of the Outputs in Case of a Fault

10.6.2 Set the switching limits (hysteresis function)
► Make sure that the function [Hno] or [Hnc] is set for the corresponding
output [OUx]�
► Select [SP1] ��� [SP4] and set the value at which the output switches�
���
► Select [rP1] ��� [rP4] and set the value at which the output is reset�
rPx is always smaller than SPx� The unit only accepts values which are
lower than the value for SPx�
���
10.6.3 Set the switching limits (window function)
► Make sure that for [OUx] the function [Fno] or [Fnc] is set�
► Select [FH1] ��� [FH4] and set the upper limit of the acceptable range�
���
► Select [FL1] ��� [FL4] and set the lower limit of the acceptable range�
FLx is always lower than FHx� The unit only accepts values which are lower
than the value for FHx�
���
10.6.4 Setting of the switch-off delay
► Select [dr1 ] ��� [dr4] and set the value between 0�2 and 60 s�
At 0�0 (= factory setting) the delay time is not active�
The switch-off delay is only active if hysteresis has been set as switching
function (OUx = Hno or Hnc)�
���
10.6.5 Response of the outputs in case of a fault
► Select [FOU1] ��� [FOU4] and set the value:
[on] = output switches ON in case of a fault�
[OFF] = output switches OFF in case of a fault�
Factory setting: [FOU1] ��� [FOU4] = [OFF]�
Faults: faulty hardware, too low a signal quality, untypical
level curve� Overflow is not considered to be a fault�
���
10.6.6 Setting of the delay time after signal loss
► Select [dFo] and set a value between 0�2 and 5�0 s�
At 0�0 (= factory setting) the delay time is not active�
Mind the dynamics of your application� In case of fast level changes it is
recommended to adapt the value step by step�
