ENGLISH

1. Mounting the AME 01, AME 02 on a

valve (Fig. 1)

Fix the AME01, AME 02 on the valve

with the nut. No tool is recommended.

2. Function switch setting (Fig. 2.X)

Fig. 2.0 How to open the actuator.

Insert the small screwdriver into the

opening on the housing (direction 1)

first and then push it in the direction

2. Remove the lid.

Fig. 2.1 On the printed board DIP

switch is available for selecting

special settings.

Fig. 2.2 Direct or inverse operation.

(Factory setting is direct).

Fig. 2.3 (Y = 0 - 10 V, factory setting)

The actuator spindle travels

downwards on rising control voltage.

Fig. 2.4 (Y = 2 - 10 V, factory settings)

The actuator spindle travels

downwards on rising control voltage.

Fig. 2.5 (Y = 0 - 20 mA)

The actuator spindle travels

downwards on rising control current.

Fig. 2.6 (Y = 4 - 20 mA)

The actuator spindle travels

downwards on rising control current.

Fig. 2.7 (Y = 10 - 0 V)

The actuator spindle travels upwards

on rising control voltage.

Fig. 2.8 (Y = 10 - 2 V)

The actuator spindle travels upwards

on rising control voltage.

Fig. 2.9 (Y = 20 - 0 mA)

The actuator spindle travels upwards

on rising control current.

Fig. 2.10 (Y = 20 - 4 mA)

The actuator spindle travels upwards

on rising control current.

Fig. 2.11 Anti-sticking cycle.

(Factory setting is OFF)

The actuator performs a full stroke

once per day.

Fig. 2.12 Reset.

Change the position off the switch to

reset.

Fig.2.13 DIP Switch Settings

The actuator has five position DIP

Switch with the next functionality:

· SW1: U/I - Input signal type selector:

Voltage input is selected, if set to OFF

position. Current input is selected, if

set to ON position.

· SW2: 0/2 - Input signal range

selector:

Input signal is in the range from 0 V to

10 V (voltage input) or from 0 mA to

20 mA (current input) if set to OFF

position. If set to ON position, the

input signal is in the range from 2 V to

10 V (voltage input) or from 4 mA to

20 mA (current input).

· SW3: D/I - Direct or inverted acting

selector:

To invert the direction of the actuator

set it to ON position.

· SW4: Reset:

To reset the commisioning positions

change the switch position.

· SW5: Anti-sticking cycle:

When set to ON, the actuator

performs one complete cycle every 24

hours to clear possible accumulation

of impurities from the valve plug and

seat.

Note: DIP switch can be set before or

after self - adjustment.

3. Wiring (Fig. 3)

Control signal

Control signal from the controller must

be connected to terminals Y (grey

wire - input signal) and COM (black

wire - common) on the AME cable.

Supply voltage

Supply voltage (24 V~ ± 10%, 50 Hz)

must be connected to the terminals

24 V (red wire) and COM (black wire).

4. Operation

After the actuator has been

connected to the 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 would 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

position of the DIP switch No. 4

(Fig 2.12). If the supply voltage is

switched off or falls below 80% for

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 the power supply

cut-out.

Note: After every dismounting the

actuator, self adjustment procedure

must be repeated!

Important: Do not dismount the actuator

in any other position but the stem up!

5. Function test

The indicator LED shows whether the

actuator is in operation or not.

Moreover, the indicator LED shows

the control status and faults:

• No light

- no operation or no power supply

• Constant light

- normal operation

• Interval light (1 Hz)

- self adjusting-mode

• Interval light (~ 3 Hz):

- power supply too low
