When switching switch 6, the stored data for
valve adaptation will be deleted and a new ini-
tialisation run will be triggered.
During operation, an initialisation run will be

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.
f Completely disconnect the power supply.
f Carry out the desired assignment (see Illust. 5 to
Illust. 7).
