To avoid injury and damage to persons and
devices, it is absolutely necessary these
instructions and Safety notes attached are
carefully read and observed prior to assembly
and commissioning.
Do not dismantle actuators with safety spring
function! Danger of injury and life in case of
improper handling!
Actuator is heavy. Handle with care to avoid
injury or product damage.
Wiring
Do not touch anything on the PCB!
Do not
remove the cover before the power supply is
fully switched off.
Max. allowed current output on terminals
4 and 5 is 4 A.
NOTE:
If AME 655 is connected as 3 point version only
DIP1 and DIP2 are active
DIP switch setting
❹
DIP1: FAST/SLoW – Speed selection
①
- FAST position; 3 (4) s/mm (see Tech. data)
- SLOW position; 6 s/mm
DIP2: DIr/INv – Direct or inverse acting
selector
②
- DIR position; the actuator is direct acting to
input signal
- INV position; the actuator is inverse acting to
input signal
DIP3: 2-10v/0-10v – Input/output
③
- 2-10V position; the input signal is in the range
from 2-10 V (voltage input) or from 4-20 mA
(current input)
- 0-10V position; 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
④
- LIN position; Linear correlation between Y
signal and stem position
- MDF position; Enables modified correlation
between Y signal and stem position. Degree
of modification depends on setting of
potentiometer CM.
Function enables to change MCV (valve and
actuator) characteristic (for example linear to
logarithmic and logarithmic to linear) and works
with all combinations of DIP switch settings.
DIP5: 100%/95% – Stroke limitation:
⑤
100% position; Full stroke
95% position; Stroke limited to 95%
DIP6: C/P – output signal mode selector
⑨
Output signal is present on terminal 4 when
position of the actuator is equal or lower
then setpoint of S4.
Output signal is present on terminal 5 when
position of the actuator is equal or lower then
setpoint of S5.
⑥
position C; output signal is present on
terminals 4 or 5 independent of the input
signal
- position P; output terminals 4 and 5 are
bridged with input terminals 1 and 3
DIP7: Uy/Iy –Input signal type selector:
⑦
- position Uy; input signal Y is set to voltage (V)
- position Iy; input signal Y is set to current
(mA)
DIP8: Ux/Ix –output signal type
selector:
⑧
- position Ux; output signal X is set to voltage
(V)
- position Iy; output signal X is set to current
(mA)
NOTE:
If DIP7 is in ON position, Y detection is disabled.
Functions accessible from cover
rESET button
Actuators AME 655/658/659 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 Self stroking mode (press and
hold for 5 seconds). See next paragraph for
mode details.
Self stroking mode
❼
Self stroking mode starts automatically
the first time when power supply is
applied to the actuator. To start self
stroking procedure
press and hold
rESET button for 5 seconds
①
until
the green light starts flashing. End positions of
the valve are automatically set and the actuator
goes to stationary mode
②
and starts
responding to the control signal.
Stand-By mode
❽
(versions AME 655/658/659)
Press the rESET button
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 now manually
operate the actuator.
Manual operation
Mechanical and electrical operation are
not allowed to be used at the same time!
Actuators AME 655/658 can be manually
positioned when in Stand-By mode or when
there is no power supply (mechanically).
Actuators AME 659 can be manually positioned
only in Stand-By mode.

Mechanical manual operation
A
Actuators AME 655/658 have a manual
operation knob on the top of the housing which
enables hand positioning of the actuator.
Mechanical manual operation shall be used
only when no power supply.
Electrical manual operation
B
Actuators AME 655/658/659 have 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 upper
button
the stem will be extracted and by
pressing the lower button
the stem will be
retracted.
