Mounting of the Actuators Type AHS ...
Attention! It is to be observed that at the quick coupling underneath the c lindric side of the safeguarding sleeve (black plastic part)
a conical part (light ellow) of the inner sleeve having a length of about 6 mm is still protruding (initial state).
Dismounting of the Actuators Type AHS …
1.) Set the actuator onto
the valve and bring it
into desired position b
turning the actuator.
2.) Screw down the actuator
on the valve b means of
screws and spring
washers.
3.) Carr out electric installation (see
page 2). The actuator “catches” the
valve rod “self-instructed” with the
first impact on the valve.
Equally possible: Turn handwheel
toward the right until the valve rod
is “caught” and the inner sleeve is
completel latched.
1.) Untighten and remove
both binding screws
from the flange.
2.) B means of a screw-
driver (of medium size)
the inner bushing
( ellow piece) under the
safet sleeve (black plas-
tic part) slide down from
the anti-torsion device (a
recess exists hereto later-
all on the slit).
3.) Take the actuator off
the valve; at the same
time press the safet
sleeve (black plastic
part) toward the valve
until the valve rod is
released.

Attention The actuators must not be installed overhead resp. not in a way that they hang down!
When installing electric lines the prescriptions for establishing power plants must be obser-
ved. Suppl voltage and suppl frequenc must conform to the data on the
name plate.
Mains supply line: Rated cross section min. 1 mm²
Mains fuse protection, on plant: max. 6 A
Mains disconnection, on plant: Before taking the hood off, e.g. for mechanical maintenance
and adjustment works, the mains feed must be switched off
with a hereto appropriate disconnection appliance. The discon-
nection appliance must be laid out in a wa that an unintentio-
nal switch-on will be prevented.
Electric connection:
• Install the connecting cable through the cable entr .
• The outer line sleeve must onl be stripped after about 1 cm behind the lead-through of the condu-
it gland.
• Lead the line through the conduit gland to the respective terminal strips and connect according to
the terminal connection diagram as is glued into the hood
• The lines must be installed and fixed in the device in a wa that the will be protected from moving
or rotating parts and won’t be damaged when taking off the hood or putting it back.
• Tighten pressure screw of the conduit gland and create effective strain relief.
DANGER:
This electric device is destined for application in power plants. During its opera-
tion this electric device has dangerous live blank parts and also moving resp. ro-
tating parts. It could therefore cause severest damages to health or material, e.g.
upon unacceptable removal of the required coverings, upon inexpert application,
false operation, setting or insufficient maintenance.
Those persons who are responsible for the safet of the plant must therefore grant that:
• onl qualified personnel will be charged with executing works on this device,
• these persons will alwa s keep available a.o. the operating instructions and the other product docu-
mentation as have been enclosed with these devices, with all corresponding works and will be obliged
to observe these documentations consistentl ,
• works on this device or works close to it are prohibited for persons who are not qualified hereto.
