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
Admissible Installation Positions
❶
Fix the AME 20, AME 30 on the valve.
❷
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!
❺①
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.
sW1: U/I
❺②
Factory settings:
Voltage control signal (0-10 V).
sW2: 2-10 V/0-10 V
❺③
Factory settings:
2-10 V.
sW3: Direct/Inverse
❺④
Factory settings:
DIRECT
sW4:---/sequential
❺⑤
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
sW5: 0(2)-5(6) V/5(6)-10 V
❺⑥
Note:
This function is available if switch No.4:
---/Sequential is set.
sW6: Proportional/3 point
❺⑦
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.
sW7: Not in use.
sW8: Not in use.
sW9: Reset
❺⑧
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.
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.
