When switching switch 5, the current position
of the stem will be saved as emergency end
position.
When switching switch 6, the stored data for

Connection of the power supply

NOTICE
Damage to the actuator due to operation
in unmounted state
The actuator can be damaged and its func-
tion be impaired when operating the actuator
electrically without valve.
f The actuator must only be connected to
the power supply after installation.
NOTICE
Damage to the control technology due to a
high peak load when switching the actua-
tor on
f Use switching components which are
designed for a short-term peak load of up
to 12 A.
Make sure that the connecting cables are
disconnected from the power supply before
installing the connecting cables.
f Carry out the assignment (see Illust. 5).
f Connect the power supply.

After having connected the power supply, the
internal energy store will be charged first. This
process takes about 3.5 minutes.
Charging of the energy store generally has
priority over the actuator functions.
Z After having charged the internal energy store, the
actuator will carry out an initialisation run. The ac-
tuator will move to the upper end position first and
then to the lower end position.
The product will be ready for operation after initiali-
sation.
Z Protect the stroke position indicator by turning the
dust cover (position (2) in Illust. 2) around by 180°.
