13.1 Initialization

NOTICE
▶ Initialisation should be carried out in a depressurised
state, initialisation force = 1/2 nominal force. When initial-
ising under operating pressure, the initialisation force (IO-
Link Index 0x90 - Subindex 3 - Force initialization) must
be adjusted.
Initialisation must be carried out under the following situ-
ations:
- Subsequent mounting of the position transmitter
- Disassembly or replacement of the drive
- Replacing the sealing elements
If the process valve is completely assembled at the factory,
initialisation has already been carried out.
Initialisation can be carried out using the following proced-
ures:
- Initialisation on site
- Initialisation via IO-Link
- Initialisation via configurable digital input (digital input must
be set to "Init")
