For delivery of the product without factory setting (e.g. for
●
delivery without valve) initialization must be carried out
once for correct operation. This initialization must be re-
peated every time that the process valve is changed (e.g.
seal replacement or actuator replacement).
1. Connect the connection cable tension-free and without
any bends or knots.
2. Switch on supply voltage.
3. POWER LED on.
4. Use suitable connectors.
5. Connect the control medium lines tension-free and
without any bends or knots.
6. Connect the pneumatic tubes and activate the pneumatic
control air supply of max. 7 or 9 bar.
7. Carry out initialisation on-site or via communication inter-
face.
Initialization is active for an unusually long time
▶ For actuators with a large air volume (filling volume), in
some circumstances it can take several minutes until ini-
tialization can be completed. Initialization is only unsuc-
cessful if an error message appears with LED signalling.
12.1 Programming the end positions
The end positions must be programmed under the following
conditions:
•
Retrofitting an 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
programmed.
The end positions can be programmed as follows:
•
On-site programming
•
Programming input (pin 5)
•
Communication interface
When programming via the communication interface, auto-
matic programming is recommended.
12.1.1 On-site end position programming

1. Connect supply voltage.
2. Briefly (>100 ms) hold a magnet (e.g. 1242000ZMA) to the
position marked PROG 1 on the housing cover.
