Set the addresses of your actuators as desired.
(Modbus topology see section 10.1 on page 15 ).
Each address must only be used once in a
Modbus network.
Z The actuator will automatically perform an initialisa -
tion run after setting of the Modbus addresses.
Z
After completion of the initialisation run and com-
missioning of the Modbus interface, the actuator will
follow the control signals.
6. Operation
6.1 Status LED
The status LED is located under the casing cover
above the terminal on the right hand side and dis-
plays the operating status of the actuator.
The status LED is visible even when the cover is
closed.

0..100%
If the value 3 has been configured in the register
address 133, the valve emergency position (0-
100 %) configured in the register address 134
will be approached in case of a bus failure (no
query by the Modbus Master for 120s).
Once the bus communication has been re-
stored, the valve will again be controlled auto -
matically according to the set operating mode.
