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.
fThe 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
fUse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.
fCarry out the assignment (see Illust. 5).
fConnectthepowersupply.
Afterhavingconnectedthepowersupply,the
internalenergystorewillbechargedrst.This
process takes about 3.5 minutes.
Charging of the energy store generally has
priority over the actuator functions.
ZAfterhavingchargedtheinternalenergystore,the
actuatorwillcarryoutaninitialisationrun.Theac-
tuatorwillmovetotheupperendpositionrstand
thentothelowerendposition.
Theproductwillbereadyforoperationafterinitiali-
sation.

NOTICE
It may not be possible to unscrew the col-
lar nut by hand
Insomecircumstances,theactuatorcloses
thevalvewiththemaximumactuatingpower
of500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!
fMovetheactuatortomidstrokeposition
withthehelpofacontrolsignal.
1. Makesurethatnodifferentialpressureisappliedto
the valve body.
2. Movetheactuatortomidstrokepositionwiththe
help of a control signal.
3. ActuateDIPswitch5,tosetthispositionasemer-
gency end position.
4. Completelydisconnecttheactuatorfromthepower
supply.
5. Loosen the collar nut.

7. Remove the actuator from the valve.
Also remove the adapter set if you do not re-
quire it any longer for this valve.
10. Reinstallation
Theactuatormustnotbeinthelowerstroke
position for correct installation.
1. Connectthepowersupply.
ZTheinternalenergystorewillbecharged.
2. Afterabout3.5seconds,movetheactuatorto
anuppertomidstrokepositionwiththehelpofa
control signal.
3. Install the actuator as described in section5.
4. Puttheactuatorintooperationasdescribedin
section 6.
5. TriggeraninitialisationrunbyactuatingDIPswitch
