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.
Mounting ❶
Fix the AME 23, AME 23 SU, AME 33 on
the valve ❷ .
Wiring ❸
AC 24 V Connect via safety
isolating transformer.
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!
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.
U/I ❹①
Factory setting:
voltage control signal (0-10 V).
2-10 V/0-10 V ❹②
Factory setting is:
2-10V.
Direct/Inverse ❹③
Factory setting is: DIRECT
---/Sequential ❹④
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.
0(2) V-5(6) V/5(6)-10 V ❹⑤
Note:
This function is available if switch No.4:
--- / Sequential is set.
Proportional/3 point ❹⑥
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.
Reset ❹⑦
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 0.1s, 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.
Function test
The indicator light shows whether the
positioner is in operation or not. Moreover,
the indicator shows the control status and
faults.
Constant light
- normal operation
No light
- no operation or no power supply
Intermittent light (1 Hz)
- self adjusting-mode
Intermittent light (3 Hz):
- power supply too low
- insufficient valve stroke (<20 s)
- end-position cannot be reached.
