5 .3 .5 Window function
The window function realizes a signal range – acceptance region –, where the switch output is set to a
definitive switch state.
The switch range is determined by input the switch point and switch back point.
The switch output is activated, if the current measuring value is inside the area that is defined by the
switch point and the reset switch point and if the set switch point delay time has been expired.
The switch output is deactivated, if the current measuring value is outside the area that is defined
by the switch point and the reset switch point and if the set reset switch point delay time has been
expired.
The actual applied measuring signal can be applied or an arbitrary value can be set as switch resp.
switch back point.
5 .3 .6 Error indication function
The switch output S1 can be alternatively used for error indication function. Doing this a switch action
happens, if the output current becomes higher than 20mA resp. lower than 4mA.
5 .4 Current output
The nominal values of the current output (4mA/20 mA) refers to the set signal zero and signal end
value.
5 .4 .1 Error signal
Defines the current output regarding operating range and if errors are registered.
A - Off >> 3.9-21mA
B - 3.8mA
C - 22mA
5 .4 .2 Invert signal
Inverts the current output.
•
4-20mA >> 20-4mA
