safety note
To avoid injury and damage to persons
and devices, it is absolutely necessary
these instructions are carefully read
and observed prior to assembly and
commissioning.
Necessary assembly, start-up, and
maintenance work must be performed
only by qualified, trained and authorised
personnel.
Prior to assembly and maintenance work
on the controller, the system must be:
- depressurised
- cooled down
- emptied
- cleaned
Please comply with the instructions of the
system manufacturer or system operator.
Do not remove the cover before the power
supply is fully switched off.
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.
Dimensions ❶
Mounting ❷
Fix the actuator AME 55, AME 56 on the
valve
❸ .
Wiring ❹
Do not touch anything on the PCB!
Switch off the power line before wire the
actuator! Lethal voltage!
Wire the actuator according to the wiring
diagram.
Control signal
Control signal from the controller must be
connected to terminals Y (input signal) and
SN (common) on the AME printed board.
Output signal
Output signal from the terminal X can be
used for indication of the current position.
Range depends on the DIP switch settings.
supply voltage
Supply voltage (24 V~ -15 to +10%, 50 Hz)
must be connected to the terminals SN
and SP.

Factory settings:
ALL switches are on OFF position! ①
Note:
All combinations of DIP switches are
allowed. All functions that are selected are
added consecutively. There is only one logic
override of functionalities i.e. the switch No.6
Proportional/3 point, which sets actuator to
ignore control signal and works as a “simple”
3-point actuator.
sW 1: U/I ②
Factory setting:
voltage control signal (0-10 V).
sW 2: 2-10 V/0-10 V ③
Factory setting is:
2-10 V.
sW 3: Direct/Inverse ④
Factory setting is:
DIRECT
sW 4:---/sequential ⑤
Two actuators can be set to work parallel
with one control signal. If the SEQUENTIAL
is set than an actuator responds to split
control signal (see 0(2)-5(6) V/5(6)-10 V).
Note:
This combination works in combination with
switch No. 5: 0(2)-5(6) V/5(6)-10 V
sW 5:
0(2)-5(6) V/5(6)-10 V ⑥
Note:
This function is available if switch No. 4:
--- / Sequential is set.
sW 6: Proportional/3 point ⑦
Actuator can operate as “simple” 3-point
actuator, if the 3-point function is selected.
Power supply should be connected on
SN and SP ports. On port 1 or 3 24 VAC
signal is connected for rising or lowering
of actuator. Return signal X indicates the
correct position.
Note:
if 3 point function is selected actuator does
not respond to any control signal on port Y.
It only rises and lowers spindle if power is
supplied on port 1 or 3.
sW 7: lOG. flow/lIn. flow ⑧
Factory setting is:
LOG. Flow (characteristic of valve is
unchanged)
Note:
If this function is used in combination with
non-logarithmic valves the characteristic
of motorised valve will be anti-logarithm
of valve’s characteristic (e.g. valve with
linear characteristic will be transformed to
quick open characteristic).

Note:
This function works proper only with
logarithmic (equal percentage) valves.
sW 9: Reset ⑩
After the actuator has been connected
to power supply, the actuator will start
the self-adjustment procedure. The
indicator LED flashes until self adjustment
is finished. The duration depends on the
spindle travel and will normally last a few
minutes. The stroke length of the valve is
stored in the memory after self adjustment
has been completed. To restart self
adjustment, change the position of RESET
switch (switch No. 9). If the supply voltage
is switched off or falls below 80 % in more
than 0.1 s, the current valve position will be
stored in the memory and all data remain
saved in the memory also after a power
supply cut-out.
