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.

Mounting ❶

Fix the AME 10 on the valve.

Wiring ❷

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

(24 V~ -15 to +10%, 50 Hz) must be connected to

the terminals SN and SP.

DIP switch settings

Factory settings:

ALL switches are on OFF position! ❸

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 ❹

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).

SW2: 2V ... 10 / 0V ... 10 ❺

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.

SW3: Direct/Inverse ❻

Actuator can be set for spindle to travel

downwards on rising control signal (DIRECT), OR

for spindle to travel upwards on rising control

signal (INVERSE).

Factory setting is:

DIRECT

EI.96.L2.1F / 73692172

SW4: ---/Sequential ➐

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

SW5: 0(2) V ... 5(6 V)/6(6) V ... 10 V ➑

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)

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)

SW6: Proportional/3 point ➒

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: LOG/LIN - Not in use

SW8: 100% k

/Reduced k

- Not in use

SW9: Reset ❿

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.
