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.
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 and installation
❶
Wiring
❷
Do not touch anything on the
PCB!
Switch off the power line before wiring the
actuator! Lethal voltage!
Wire the actuator according to the wiring
diagram.
Functions accessible from cover
STAND BY MODE
❸
Pressing the STAND BY/RESET/LOCK button
for 3-6 sec. and releasing it after 1x green LED
blink causes the actuator to activate STAND
BY MODE. The actuator will not react on any
change of the control signal until it is switched
back again to NORMAL MODE by pressing the
button as mentioned before. During STAND BY
MODE, the actuator can be moved manually
or can be switched to RESET MODE or LOCK
MODE by pressing the button as described in the
according operating modes.
LOCK MODE
Pressing the STAND BY/RESET/LOCK button for
9-12 sec. and releasing it after 3x red LED blinks
causes the actuator to activate LOCK MODE. The
actuator can not be brought to STAND BY MODE
or RESET MODE until it was switched back again
to NORMAL MODE by pressing the button as
mentioned before (releasing the button now
after 3× green LED blinks). During LOCK MODE,
the actuator works just as described in normal
or positioning mode, but with partly locked
button-functions (shown with 1x or 2× red LED
blinks).
Self stroking mode = RESET MODE
❹
Pressing the STAND BY / RESET / LOCK button
for 6-9 sec. and releasing it after 2× green LED
blinks causes the actuator to start
self stroking
procedure
:
The bi-colour LED flashes green at 1 sec. intervals
during calibration procedure, which begins by
extracting the stem. When the maximum force is
detected (at the valve end position), the actuator
then retracts the stem, until the maximum force
is once again detected (on the other valve end
position). The actuator will then automatically
enter to NORMAL MODE and respond to the
control signal.
Positioning mode
The bi-colour LED is green and stays on during
positioning of the actuator according to the
control signal
Normal mode
When the positioning of the actuator is finished
the LED flashes green every 6 seconds.
REMARK
Pressing the STAND BY/RESET/LOCK button for
more than 12 sec., no activation/deactivation
occures.
Manual override
NOTE:
If manual override has been used then
control and return signal are not correct
until the actuator reaches its end position.
LED function indicator
➎
Green – initialization (RESET), set-point position,
transition indicator
Red - indicates STAND BY and Failure mode.
Green
:
• Flashing light (once every 6 sec.)
- actuator reached set-point acc. to Y signal
• No light
- no operation or no power supply
• Flashing light (~ 1Hz)
- self adjusting mode.
Red
:
• No light
- no operation or no power supply
• Constant light
- fault condition occurred
• Flashing light (2 Hz)
- STAND BY
- power supply too low
- initial self-adjusting time too short due to
too short valve strokes
- failure during self calibration.

Jumper / DIP switch settings
❼
Jumper
①
: U/I - Input signal type selector
DIP switches
Factory settings:
ALL switches are in OFF position. The jumper is set
to “U”.
NOTE:
All combinations of DIP switches are
allowed. All functions that are selected are added
consecutively.
SW 1: Not used
SW 2: 0/10 - Input signal range selector
②
SW 3: D/I - Direct or inverse acting selector
③
SW 4: Not used
SW 5: Not used
SW 6: Not used
SW 7: LIN/LOG - Linear or logarithmic flow
characteristic
❽
SW 8: Smart function selector
If set on ON position the actuator enables
special anti oscillations algorithm.
If set on OFF position the actuator does not try to
detect any oscillations in the system.
