10.2.2 Manual teach function
For devices without pilot valve:
The end positions are captured and saved manually by the user.
With the IO-Link and AS-Interface variant, the teach function can also be started via the bus com-
munication (see respective parameter list) or with all variants of the REV.3 versions with the Bürkert
Communicator.
Essential requirements:
•
The device is mounted on the actuator.
•
The supply voltage is connected.
•
The compressed air supply is connected.
•
So that the correct reference conditions are identified, the pilot pressure must correspond to the operating
conditions.
•
Provide the possibility for the user to switch the pneumatic actuator (open and closed).
