Switching Output X: Definition Of The Switching Characteristic - Bosch Rexroth WGM Operating Instructions Manual

5.1.7.1 Switching output x: Definition of the switching characteristic

The switching characteristic for the output is defined in the following menu:
The following options are available:
Hysteresis function
Normally open or normally closed contact
function in which the output signal is set when
the set switching point is exceeded. If the value
falls below the set switch-back point, the output
signal is deleted.
Hysteresis function as normally open contact
Normally open contact (
the PNP switching output is closed above the
switching point SPx and opens again when the
value falls below the switch-back point rPx.
Hysteresis function as normally closed contact
Normally closed contact (
the PNP switching output is open above the
switching point SPx and closes again when the
value falls below the switch-back point rPx. See
also the explanations in the drawing below.
Window function
Normally open or normally closed contact
function that defines a signal window. When the
measuring window is reached, the output signal
is set, when leaving the measuring window it is
deleted again.
Window function as normally open contact
Here, normally open contact (
the PNP switching output is closed if the value
is within the window.
Otherwise the switching output is open.
Window function as normally closed contact
Here, normally closed contact (
the PNP switching output is open if the value
is within the window. Otherwise the switching
output is closed.
Frequency output
If the output is defined as a frequency output,
a rectangular signal with a frequency between
1 Hz and 100 Hz is output proportional to the
measured value.
Notice: To increase the edge steepness of the
rectangular signal, it is recommended to fit the
switching output with a 10 kΩ resistor.
