12 Programming the end positions
The end positions must be programmed under the following conditions:
- Retrofitting the electrical position indicator
- Replacing the actuator
- Replacing the diaphragm
If electrical position indicators have been fitted to the process valve at the factory, the end positions will already have been pro-
grammed.
The end positions can be programmed as follows (depending on the order version):
- On-site programming
- Programming input (pin 5)
- Communication interface
When programming via the communication interface, automatic programming is recommended.
