Safety Note
To avoid injury of persons and damages to
the device, it is absolutely necessary to read
and observe these instructions carefully.
Necessary assembly, start-up, and
maintenance work must be performed by
qualified and authorized personnel only.
Prior to assembly and depressurizing the
system.
Please comply with the instructions of the
system manufacturer or system operator.
AC 24 V
Connect via safety isolating transformer.
Mounting
❶
Fix the actuator on the valve
.
Wiring
❸
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.
DIP switch settings
❹
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.
SW 1:
U/I
❹ ①
Actuator can responde to a voltage or
current control signal. With switch No.1: U/I
actuator can be set either to operate with
a voltage control signal (actuator responds
to signal between 0 … 10 V), or current
control signal (actuator responds to signal
between 0 … 20 mA).
Factory setting
:
voltage control signal (0 … 10 V).
SW 2:
2V … 10 / 0V … 10
❹ ②
Actuator can be set to response on a
control signal from 2 V, or 0 V. If the
actuator is set to current signal than it
responds to control signal from 4 mA or
0 mA.
Factory setting is:
2 … 10V.
SW 3:
Direct/Inverse
❹ ③
Actuator can be set for spindle to travel
downwards on decreasing control signal
(DIRECT), OR for spindle to travel upwards
on rising control signal (INVERSE).
Factory setting is:
DIRECT
SW 4:
---/Sequential
❹ ④
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) V … 5(6 V) /
6(6) V … 10 V).
Note:
This combination works in combination with
switch No.5: 0(2) V … 5(6 V) / 6(6) V … 10 V
SW 5:
0(2) V … 5(6 V)/6(6) V … 10 V
❹ ⑤
Note:
This function is available if switch No.4:
--- / Sequential is set.
Actuator can be set to match the range of the
control signal:
2 … 6 V (switch No.2: 2 V … 10)
0 … 5 V (switch No.2: 0 V … 10)
4 … 12 mA
(switch No.2: 2 V … 10)
0 … 10 mA
(switch No.2: 0 … 10)
OR
6 … 10 V
(switch No.2: 2 V … 10)
5 … 10 V
(switch No.2: 0 V … 10)
12 … 20 mA
(switch No.2: 2 V … 10)
10 … 20 mA
(switch No.2: 0 … 10)
SW 6:
Proportional/3 point
❹ ⑥
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
❹ ⑦
Large AB-QM valve has linear characteristic.
With setting switch to LIN flow the
characteristic remains linear. With setting
switch to LOG flow the characteristic of
actuator is modified the way that actuator
and valve work together as valve with LOG
characteristic.
Factory setting:
LOG. Flow (characteristic of valve is
unchanged)
SW 8:
100% K
VS
/RED. K

❹ ⑧
To be set on OFF position.
SW 9:
Reset
❹ ⑨
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.
