Safety Notes
To avoid personal injury and damage
to devices, it is absolutely essential for
these instructions and safety notes to
be read carefully and reviewed prior to
assembly and use.
Do not dismantle actuator with the safety spring
function! There is risk of injury and death in the
event of improper handling!
The actuator is heavy. Handle with care to avoid
injury or product damage.
Wiring
Do not touch anything on the PCB!
Do not remove the service cover
before the power supply is fully
switched off.

1. Start-up of system *
2. Set flow rate on a motorized valve over
which the differential pressure is controlled,
to about 50 % *
3. Adjustment
• Observe pressure indica tors *
Enter the Stand-By mode for manual
operation
• Pushing the button on the actuator
increases the set-point (squeezing the
spring)
• Pushing the button redu ces the
set-point (stretching the spring)

DIP switch setting ❺
S1
S1/DIP 1
Input signal type selector:
OFF: Input signal Y is set to voltage (V)
ON: Input signal Y is set to current (mA)
S1/DIP 2
Output signal type selector:
OFF: Output signal X is set to voltage (V)
ON: Output signal X is set to current (mA)

S1/DIP 3
Direct or inverse acting selector (Fig. 2):
OFF: Actuator is direct acting to input signal
ON: Actuator is inverse (reverse) acting
to control signal (only for AMEI 6 iNET in
combination with AFA 2)
S1/DIP 4
Normal or sequential mode selector:
OFF: Actuator is working in range 0(2)-10 V or
0(4)-20 mA.
ON: Actuator is working in sequential range; 0-5
V or (0-10 mA) or (5-10 V) or (10-20 mA).
Signal range selector S1/DIP 6 sets the
sequential range
S1/DIP 5
0-10 V/2-10 V – Input/output
OFF: 0-10 V; input signal is in the range from 0-10
V (voltage input) or from 0-20 mA (current input)
ON: 2 –10 V; input signal is in the range from
2-10 V (voltage input) or from 4-20 mA (current
input)
Signal range selector S1/DIP 1 & DIP 2 sets Y and
X signal.
S1/DIP 6
Sequential range selector:
OFF: 0-5 V or (0-10 mA)
ON: 5-10 V or (10-20 mA).

S2/DIP 4*
OFF: Analog signal (V/mA)
Actuator operates in analog mode
ON: MOD BUS
Actuator operates in digital mode
*In analog mode S2/DIP 4 = OFF, DIP switches
S1/DIP 1-7 work as active functions.
In digital mode S2/DIP 4 = ON , DIP switches
S1/DIP 1-7 work as a digital addresses.
In digital mode Modbus RS485 could be used
either for the monitoring purposes or for the
AMEi 6 actuator positioning..
Calibration ❻
Calibration to the desired pressure actuator
stroke (min-max spring setting).
Before calibration drive the actuator out of end
positions (minimal gap between sliders ①,②
and pin on the end switch ③ has to be ensured).
To start calibration procedure, press and hold
RESET button for 5 seconds until the green light
starts flashing. End positions of the actuator are
automatically adopted based on pre-set end
switch positions sliders ①,②. Actuator goes
to the stationary mode and starts responding
to the control signal. Depends on min-max Δp
setting (position of sliders ① and ②), calibration
may take up to ~1 h (in case of max available Δp
range-stroke is set).
Calibration procedure need to be repeated
every time when min/max spring setting
is changed (position of sliders ① and ② is
changed).
