Safety Notes
To avoid personal injury and damage
to devices, it is absolutely essential for
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!
Switch off the pump and power line before
mounting and wiring the actuator.
The actuator is heavy. Handle with care to avoid
injury or product damage.

SW1: FAST/SLOW – Speed selection ①
- FA S T;
- SLOW;
SW2: DIR/INV – Direct or inverse acting
- DIR; the actuator is directly reacting to input
- INV; the actuator is inversely reacting to
SW3: 2-10V/0-10V – Input/output ③
- 2-10V; the input signal ranges from 2-10 V
- 0-10V; the input signal ranges from 0-10 V
Signal range selector sets Y & X signals.
SW4: LIN/MDF – Characteristic modification
- LIN; linear correlation between Y signal and

The function enables to change MCV (Motorised
Control Valve) characteristic (for example
linear to logarithmic and logarithmic to linear)

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 redyellow 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
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 antioscillation 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 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.
Final step of electrical connection ❼
LED signalisation ❽
Calibration mode ❾
Calibration 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 ① until the green
light starts flashing. End positions of the valve
are automatically set and the actuator goes into
stationary mode ② and starts responding to the
control signal.
Manual Operation ❿
Mechanical and electrical operation
must not be used at the same tim e!
AME 655-1/658 SD-1/658 SU-1 and AME 685-1
actuators can be manually positioned when in
standby mode or when there is no power supply
(mechanically).
Actuator type
Stand-By mode
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 655-1/658 SD-1/658 SU-1 and AME 685-1
actuators have a knob & crank on the top of the
housing which enables manual positioning of
the actuator.

Electrical manual operation
AME 655-1/658 SD-1/658 SU-1 and AME 685-1
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
button, the stem will be extended and
by pressing the button, the stem will be
retracted.
