ENGLISH
Safety Notes
To avoid personal injury and damage to
devices, it is absolutely essential for these
instructions and safety notes to be read
carefully and reviewed prior to assembly and use.
Do not dismantle actuator with the safety spring
function! There is risk of injury and death in the
event of improper handling!
The actuator is heavy. Handle with care to avoid
injury or product damage.
Disposal instruction
This product should be dismantled and
its components sorted, if possible, in
various groups before recycling or
disposal.
Always follow the local disposal regulations.
Wiring
Do not touch anything on the PCB! Do
not remove the cover before the power
supply is fully switched off.
NOTE: Only basic function as SW1 (Fast/Slow) and
SW2 (INV/DIR) are active when is no power supply
on terminal SP and AME actuator operated as AMV.

SW1: FAST/SLOW – Speed selection ①
- FAST; 2.7 s/mm
- SLOW; 6 s/mm
SW2: DIR/INV – Direct or inverse acting
selector ②
- DIR; the actuator is directly reacting to input
signal
- INV; the actuator is inversely reacting to input
signal
SW3: 2-10V/0-10V – Input/output ③
- 2-10V; the input signal ranges from 2-10 V
(voltage input) or 4-20 mA (current input)
- 0-10V; the input signal ranges from 0-10 V
(voltage input) or 0-20 mA (current input)
Signal range selector sets Y & X signals.
SW4: LIN/MDF – Characteristic modification
function ④
- LIN; linear correlation between Y signal and
stem position
- MDF (Modified); enables modified correlation
between Y signal and stem position. Degree
of modification depends on setting of
potentiometer CM.
The function enables to change MCV (Motorised
Control Valve) characteristic (for example linear to
logarithmic and logarithmic to linear) and works
with all combinations of DIP switch settings.
SW5: 100 %/95 % – Stroke limitation ⑤
Adjustable stroke limitation of retracted or
extended actuator stem position.
DIP switch 5 needs to be reset prior to procedure
(5.2) to 100 % (5.1) and set to 95 % (5.3) until the

self-stroking procedure has concluded (5.4).
Retracted icon (5.5) on actuator will blink red-
yellow when actuator stops at max. retracted stem
position (5.5) and will blink as long as it is not set to
a new retracted position (5.6) by pressing buttons
flow on flow meter). Press and hold reset button
for 5 seconds (5.7) and then set new extended stem
position by pressing buttons
Extended icon (5.8) will blink red-yellow as long as
it is not set to new extended position by pressing
and holding reset button for 5 seconds.
SW6: C/P – Output signal mode selector ⑥
① An output signal is present on terminal 4 when
the position of the actuator is equal to or
lower than the S4 set point. An output signal
is present on terminal 5 when the position of
the actuator is equal to or higher than the S5
set point.
SW6: C; provides a constant output signal on
terminals 4 & 5, regardless of the input
signal.
SW6: P; provides a pulse signal through
parallel or cascade electrical wiring
input 1 & 3 dependents from the
controller to output terminals 4 & 5.
SW7: Smart function selector: ⑦
- OFF; the actuator does not try to detect
oscillations in the system
- ON; the actuator enables special anti-oscillation
algorithm – In case control signal Y on certain
point oscillates looking from time perspective,
algorithm starts to lower the amplification of
the output to the valve. Instead of having static
characteristics actuator changes to dynamic
characteristics. After the control signal does not
oscillate anymore, output to the valve slowly
returns back to static characteristics.
SW8: Uy/Iy – Input signal type selector: ⑧
- Uy; input signal Y is set to voltage (V)
- Iy; input signal Y is set to current (mA)
SW9: Ux/Ix – Output signal type selector: ⑨
- Ux; output signal X is set to voltage (V)
- Ix; output signal X is set to current (mA)
NOTE: Y detection is disabled if SW8 is set to ON
position and SW3 is set to OFF position.
Functions accessible from cover
RESET button
The actuator has an external RESET button, which is
located on the top cover of the actuator next to the
LED indicators. With this button you can enable or
disable standby mode (press once) or self-stroking
mode (press and hold for 5 seconds). See next
paragraph for more details.

Self-stroking mode ❼
Self-stroking mode begins automatically the
first time the actuator is powered on. To start
the self-stroking procedure, press and hold the

Manual Operation
Mechanical and electrical operation
must not be used at the same time!
The actuator can be manually positioned when in
standby mode or when there is no power supply
(mechanically).

Stand-By mode
❽
Press the RESET button for 1 second to enter
standby mode. The actuator stops in the current
position and stops responding to any control
signal. A red light remains constantly lit. You can
now manually operate the actuator.
Mechanical manual operation
The actuator has a knob & crank on the top of the
housing which enables manual positioning of the
actuator.
Use Mechanical manual operation only
when the power is disconnected.
Mechanical and electrical operation are
not allowed to be used at the same time!
Electrical manual operation
The actuator has two buttons on the top of the
housing that are used for electrical manual
positioning (up or down), if the actuator is in
Stand-By mode. First press the RESET button
until the actuator goes to Stand-By mode (red
LED is lit). By pressing the button
will be extended and by pressing the button
the stem will be retracted.
