5.4 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.
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.
fCompletelydisconnectthepowersupply.
fCarry out the desired assignment (see Illust. 5 to
Illust. 7).
fConnectthepowersupply.
ZAfterhavingconnectedthepowersupplyforthe
rsttime,theactuatorwillcarryoutaninitialisation
run.
Theproductwillbereadyforoperationafterinitiali-
sation.

6.3 Manual setting
NOTICE
Damage to the actuator due to manual po-
sitioning of the stem beyond the dened
range
The actuator can be damaged and its func-
tion be impaired during manual setting.
fOnlymovetheadjustmentstemwithlittle
force.
fTurn the adjustment stem back by half a
turn as soon as you feel a resistance in
theupperorlowerstrokeposition.
NOTICE
Damage to the actuator due to manual
setting during electrical operation
The actuator can be damaged and its func-
tionbeimpairedwhenusingthemanual
setting during electrical operation of the
actuator.
fCompletely disconnect the actuator from
thepowersupplybeforeusingthemanual
setting.
1. Completelydisconnecttheactuatorfromthepower
supply.
2. Open the cover for manual setting (adjustment
stem) (see position 2 in Illust. 9).
3. Move the actuator into the desired stroke position
using a 4 mm Allen key.
The actuator has to be initiated after manual
setting.
Aninitialisationrunwillbetrigged:
- WhenswitchingDIPswitch6
(see Illust. 4).
- If a valve end position is approached dur-
ing operation.
- After 7 days at the latest.
7. Maintenance
The actuator is maintenance-free.

CAUTION
Risk of burns due to hot components
Anunprotectedcontactwithhotcomponents
may lead to burns.
fAllowtheproducttocooldownbefore
workingonit.
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!
fUse the manual setting option.
1. Make sure that no differential pressure is applied to
the valve body.
2. Completelydisconnecttheactuatorfromthepower
supply.
3. Check the stroke position of the actuator.
4. If the actuator is not in the upper to medium stroke
position,movetheactuatorintothemediumstroke
positionwiththehelpofthemanualsetting(see
section 6.3).
5. Loosen the collar nut.
6. Pressthepushbuttontoreleasethelatchedvalve
stem until stop and keep it pressed.
7. Remove the actuator from the valve.
Also remove the adapter set if you do not re-
quire it any longer for this valve.
9. Reinstallation
Theactuatormustnotbeinthelowerstroke
position for correct installation.
1. Beforereinstallation,movetheactuatortoanupper
tomediumstrokepositionwiththehelpofacontrol
signal or the manual setting (see section 6.3).
2. Install the actuator as described in section 5.
3. Puttheactuatorintooperationasdescribedin
section 5.2 .
4. TriggeraninitialisationrunbyswitchingDIPswitch
6 (see Illust. 4).
ZThe actuator is ready for operation.
