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
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 service cover before the
power supply is fully switched off.
Max. allowed current output on
terminals 4 and 5 is 4 A. Min. power is 3W.
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 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
- 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 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
to set the required position (observe 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
An output signal is present on terminal 4 when
①
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
❶
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
③
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:
- 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 actuators 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.

❻
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
RESET button for 5 seconds
until the green
①
light starts flashing. End positions of the valve
are automatically set and the actuator goes into
stationary mode and starts responding to the
②
control signal.
Manual Operation
❽
Mechanical and electrical operation
must not be used at the same time!
AME 655/658 actuators can be manually positioned
when in standby mode or when there is no power
supply (mechanically).

Stand-By mode (versions AME 655/658)
Press the RESET button ① 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 ②.
Mechanical manual operation
AME 655/658 actuators have 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
AME 655/658 actuators have two buttons on the
top of the housing that are used for electrical
manual positioning (up or down) if the actuator is
in standby mode. First, press and hold the RESET
button ① until the actuator goes to standby mode
(red LED is lit). By pressing the
stem will be extended and by pressing the
button, the stem will be retracted.
