For devices with pilot valve:
Theteachfunctionautomaticallyidentiesandsavestheendpositionsofthevalve.
With the IO-Link variant, the teach function can also be started with an acyclic IO-Link parameter (see
parameter list) or with the Bürkert Communicator.
With the büS variant, the teach function can also be started 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identied,thepilotpressuremustcorrespondtotheoper-
