Product features
Simple attachment to the neck of the
valve by means of a clamping arrangement.
Semi-automatic coupling of the
valve stem to the actuator spindle. The
actuator can be rotated through 360° on
the neck of the valve.
Functional reliability
The actuator is short-circuit-proof and
protected against polarity reversal.
Manual operation
Inserting a 5 mm hexagonal key and turning
it clockwise causes the actuator spindle
to extend from the actuator housing and
close the valve. The spindle remains in
this position until the power supply is energized
(controller takes first priority).
Position indication
The nominal stroke of the valve is indicated
mechanically on the mounting bracket
and preset. There is a twin-colour LED
status indicator under the cover of the
housing.
Safety note
The linear actuator contains no components
which the user can replace or repair.
Note
The mounting bracket is an integral part of
the actuator.

Under the cover of the actuator are the terminals
for connecting the lead, the control
devices S1, S2 and S3 and the LED indicator
H1.
By setting the slide switch S3 appropriately
or by pressing push-buttons S1 and S2
it is possible to configure the actuator very
simply on-site to suit actual requirements
when changes from the factory settings
are needed.
Note
With the AV.. MFT2 types, slide switch
S3.2 is the valve closing point. The closing
point of the SuperCompact control
valve is in the down position which is the
standard for the AVS actuator and cannot
be changed.

(Adaption)
Description
The valve covers the full stroke in maximum running time and
verifies the adapted stroke to ensure that both end-points are
reached (H = 0% and H = 100%).
The parameterized stroke is pre-programmed in the linear actuator
(parameterized stroke = Nominal stroke in function DN, see Page 8).
When the adaption button S2 is pressed the actuator moves upward
from the closing point (down) by the amount of the parameterized
stroke and performs synchronization. At the same time the control
signal and the running time are adapted to this parameterized stroke.

Fault; repeat adaptation
After power interruption (> 2 sec.). By the next closing movement
the valve will be automatically synchronized in the
chosen closing point. The LED indicator will change from a
red flashing into a green steady light.

The actuator is maintenance-free. The
twin-colour LED indicator is under the
cover of the actuator; the indicator shows
actual actuator status. It also allows simple
commissioning if the factory settings
need to be changed.

also available in addition to the LED status indicator.
MP communication The actuator is prepared for room bus operation.
Up to 8 actuators can be wired in parallel.
!
Not allowed with the
equal-percentage
characteristic.
Slide switch S3.2 must
be in the ON position
(linear).
Multi-Function Technology allows optimum
matching of parameters to the different
needs of an installation. The parameters
are either entered as standard
values at the factory or altered subsequently
using an MFT-H adjuster.
Bold type in the table means standard
factory setting.
*3-point is only allowed when S3.2 is set to the
ON position (linear).
Instead of an analogue measuring voltage
it is also possible to read and write digital
data at the U 5 connecting terminal using a
suitable interface.
