7 Setup
VEGAPOINT 21 • Transistor (NPN/PNP)
56623-EN-210210
Depending on the selected application, you can produce the cor-
responding occultation states and transfer them directly.
7.4.2 Extended functions
In this menu item you can select the general settings for the output.
Transistor function
For devices with transistor output, you can set the function of the
output.
•
Functional principle PNP
•
Functional principle NPN
With the outputs
Function output (OU1)
In this menu item you can set the function of the two outputs indepen-
dently of each other.
Closing contact = HNO (Hysterese Normally Open)
Opener = HNC (Hysterese Normally Closed)
Closing contact = FNO (Window Normally Open)
Opener = FNC (Window Normally Closed)
Hysteresis function (HNO/HNC)
The hysteresis has the task of keeping the switching state of the
output stable.
When the switching point (SP) is reached, the output switches and
remains in this switching state. Only when the reset point (RP) is
reached does the output switch back.
If the measured variable moves between switching and reset point,
the state of the output does not change.
