8.1.2 Operating level
The operating level is active while the actuator is in the automatic mode. In this level, import-
ant information on the operation is shown, the operating mode is selected and the initializa-
tion started. The other levels are accessible from the operating level.
All the parameters of the operating level as well as fatal and EEPROM errors are listed in the
'Malfunctions' section.
8.1.2.1 Selecting the operating mode
The actuator is normally in automatic mode indicated by the icon (displayed in Code 0 to

set in the configuration level.
In manual mode, the actuator stem moves to the adjusted manual positioning value. An ac-
tive manual mode is indicated in Code 0 by the icon.
