Actuators for modulating & floating control
AME 655-1, AME 685-1 – without safety function
AME 658 SU-1, AME 658 SD-1 – with safety function (spring up/down)
Description
The AME 655-1, 658 SU/SD-1 and 685-1 series
of motor actuators are suitable in providing
valve control to the demands of district heating/
cooling, heating, ventilation, and air conditioning
applications.
The AME658 series of actuator provides safety
function in either open or closing of the valve in
the event of power loss. For the AME 655-1 and
AME 685-1 this feature is not included.
The actuators can be wired in either a
modulating or floating control dependent on
the requirements of the electronic controller’s
output.
The motor actuators AME 65x are assembled
with the AB-QM series of pressure independent
control valve for the sizes ranging from 5”
(DN 125) to 6” (DN 150).
The motor actuators AME 685-1x are assembled
with the AB-QM series of pressure independent
control valve for the sizes ranging from 8”
(DN 200) to 10” (DN 250).
Features:
•
Manual operation mechanical and/or electrical
• Position indication, LED signalization
• Selectable speed 2 or 6 s/mm for AME 655-1
• Selectable speed 4 or 6 s/mm for
AME 658 SU/SD-1
• Selectable speed 3 or 6 s/mm for AME 685-1
• Automatic adaptation of stroke to valve’s end
positions that reduces commissioning time
(self calibration of actuator travel)
• Integrated auxilliary switch
• Characteristic optimization
• Adjustable stroke limitation
• Anti-oscillation function
• Pulse or continuous output signal (4&5)
• Voltage or current output signal X

or 4-20mA control signal during normal
operation the actuator will stay in the last
known position, until a valid control signal is
present again.

Actuator operating modes
LED operating mode indicator
The three-colour (green/yellow/red) LED function
indicators are located on the actuator cover. They
indicate different operating modes.
RESET button
Actuators AME 655-1, 658 and 685-1 have external
RESET button which is located on top cover of the
actuator next to LED indicators. With this button
you can enter or exit Stand-By mode (press once) or
calibration mode (press and hold for 5 seconds). See
next paragraph for mode details.
Operating modes
• Calibration mode
The calibration of the actuator’s travel
automatically initiates the first time when
power supply is applied to the actuator. To
initiate the calibration mode, press and hold
RESET button for 5 seconds until the green
light starts flashing. End positions of the valve
are automatically set and the actuator goes to
stationary mode and starts responding to the
control signal.
• Stand-By mode
(versions AME 655/658)
Press the RESET button for 1 sec. to enter
Stand-By mode. The actuator stops in current
position and stops responding to any control
signal. Red light is constantly lit. You can
manually operate the actuator with mechanical
handle or control buttons. This mode can be
very useful during the commissioning of other
equipment, or for service purposes. In this mode
you can also set positions of the additional
switches. To exit Stand-By mode press the RESET
button again.
• Positioning mode
The actuator is operating automatically. The
stem is extending or retracting according to the
control signal. When positioning is finished the
actuator goes to stationary mode. If for one or
another reason floating signal (terminally 1 and
3) and Y signal would be present at the same
time, floating signal will take precedence.
• Stationary mode
The actuator is operating without errors.
• Error mode
Working temperature is too high - check the
ambient temperature.
Stroke is too short - check the connection with
valve and valve operation, or check if valve is
blocked.

DIP switch setting
The actuator has a selection of DIP switches (Fig. 1)
under the service cover.
DIP1: FAST/SLOW – Speed selection
- FAST; 2 s/mm or 4 s/mm
- SLOW; 6 s/mm
DIP2: DIR/INV – Direct or inverse acting
selector (Fig. 2):
- DIR; the actuator is direct acting to
input signal
- INV; the actuator is inverse (reverse) acting to
control signal
DIP3: 2-10 V/0-10 V – Input/output
- 2-10 V; the input signal is in the range from
2-10 V (voltage input) or from 4-20 mA
(current input)
- 0-10 V the input signal is in the range from
0-10 V (voltage input) or from 0-20 mA
(current input)
Signal range selector sets Y and X signal.
DIP4: LIN/MDF – Characteristic modification
function (Fig. 3):
- LIN ; Linear correlation between Y signal and
stem position
- MDF (Modified) position; 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.
DIP5: 100%/95% – Stroke limitation (fig.4):
- Set new maximum retracted position of the
actuator
- Set new minimum extended position of the
actuator.
DIP6: C/P – Output signal mode selector (Fig. 5.):
- 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.
- DIP6 position C provides a constant output
signal on terminals 4 or 5, regardless of the
input signal.
- DIP6 position P provides a pulse signal
through parallel or cascade electrical wiring
input 1 and 3 dependents from the controller
to output terminals 4 and 5.

DIP7: Smart function selector:
- OFF ; the actuator does not try to detect
oscillations in the system
- ON ; actuator enables special anti-oscillation
algorithm – see section on anti-oscillation
algorithm
DIP8: Uy/Iy –Input signal type selector:
- Uy; input signal Y is set to voltage (V)
- Iy; input signal Y is set to current (mA)
NOTE:
Y detection is disabled if DIP8 is set to ON positions
and DIP3 is set to OFF position.
DIP9: Ux/Ix –Output signal type selector:
- Ux; output signal X is set to voltage (V)
- Ix; output signal X is set to current (mA)
Anti oscillations algorithm
(SW 7 in position ON)
The actuator has special anti oscillations
algorithm. In case control signal Y on certain
point oscillates (Fig. 1) looking from time
perspective, algorithm starts to lower the
amplification of the ouput 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.
Fig. 5
Valve position X signal (V)
Oscillation
Harmonic oscillations are high frequency
oscillations with low amplitude that vary around
its own equilibrium value and not around
set-point temperature. They can appear in up to
70 % of control time, even though the system is
properly commissioned. Harmonic oscillations
have negative influence on control stability, and
lifetime of the valve and actuator.
Fig. 1
Smoothing function
The smoothing function implemented in the
new 2nd generation of anti-oscillation function
reduces harmonic oscillations; the actual
temperature is closer to the set-point (desired
temperature). Smoother operation increases
lifetime of the valve and actuator. This saves
energy and reduces costs in general.
