NOTICE
Damage to the stem in unmounted state
If you operate the actuator electrically
withoutvalve,thestemmaybedamagedby
exceedingthedenedrangeofextension.
fOnly operate the product in mounted
state
Afterhavingconnectedthepowersupply,the
internalenergystorewillbechargedrstbefore
the actuator reacts.
Charging of the energy store generally has pri-
ority over the actuator functions.

6.2 Normal operation
The actuator is automatically controlled via the con-
trol technology.
6.3 Emergency control function
ZIftheoperatingvoltagefails,theactuatorwillmove
to the set emergency end position.
ZOnce the operating voltage has been restored, the
energystorewillbechargedrst.
ZAfterthat,theactuatorwillfollowthesignalsofthe
control technology.
Theemergencycontrolfunctionwillonlybe
available after successful completion of the
initialisationrun(displayedbyaconstantlylit

may lead to burns.
fAllowthevalvetocooldownbeforework-
ing on it.
NOTICE
It may not be possible to unscrew the
collar nut by hand
Without operating voltage, the actuator may
closethevalvewiththemaximumactuating
powerof200N.Inthiscase,thecollarnut
cannolongerbeunscrewedbyhand.
fDo not use pliers or similar to loosen the
collarnut!
1. SettheDIPswitch6to"ON"(seesection5.2 on
page 9).
2. Disconnecttheactuatorfromthepowersupply.
ZTheactuatorwillmovetotheupperstrokeposition.
3. Disconnect all electrical connections.
4. Loosen the collar nut.
5. Remove the actuator from the valve.
