8 Operation

After connecting the supply voltage, the ac-
tuator is ready for use.

8.1 Three-step operation

In three-step operation, the actuator stem is
moved in the corresponding direction by ap-
plying a signal to the terminal eL or aL (see
Fig. 8-1).
Actuators with fail-safe action additionally
require a constant supply voltage (see the
'Installation' section).
