The safe output state can be selected in the parameter out.E.
Note:
Switching hysteresis: 0.05 x (SP.Hi – SP.Lo).
6.2 Alarm
If the control function Cnt is set and the alarm function d.FnC = ON, the display blinks with a
frequency of about 2 Hz when the output is switched on (see Fig. 6.1).

6.3 Filter
Undesirable signal fluctuations can be suppressed through the adjustable filter in the
parameter td “Filter time constant” (see Fig. 6.2 and Table 7.2).
The filter time constant can be set within the range 0…10 seconds. The higher the value, the
slower the display reaction to changes of the input signal and the lower the susceptibility to
interference is. The filter is deactivated if td = 0.
