Safety Note
To avoid injury and damage to
persons and devices, it is absolutely
necessary these instructions are
carefully read and observed prior to assembly
and commissioning.
Necessary assembly, start-up, and
maintenance work must be performed
only by qualified, trained and authorised
personnel.
Prior to assembly and maintenance work on
the actuator, the system must be:
- depressurised
- cooled down
- emptied
- cleaned
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
With STAND-BY/RESET-button located on the
top of the cover it is possible to enter two
function modes.
Self stroking mode ❸
Self stroking mode starts automatically the
first time when power supply is applied to
the actuator. To manually start self stroking
procedure afterwards press and hold STAND-
BY/RESET-button for 5 seconds until the green
light starts flashing.
Self stroking procedure starts with extracting
the actuator stem. When maximum force
is detected (at the end valve position) the
actuator retracts the stem until the maximum
force is detected again (on the other valve
end position).
End positions are set and the actuator goes
to normal mode and starts responding to
the control signal.
STAND-BY MODE
- Manual operation ❹
Press the STAND-BY/RESET-button to enter
STAND-BY mode. The actuator stops in
current position and stops responding to
any control signal. Red light is flashing in
2 sec. interval. You can manually control
the actuator (manual operation- see next
section).
This mode can be very useful during the
commissioning of other equipment, or for
service purposes.
To exit Stand by mode press the
STAND-BY/RESET-button again.
Manual operation
Manual operation can be done by means of
control knob on actuator housing.
To manually operate the actuator:
• Disconnect control signal
• Adjust valve position using the control
knob (observe the rotation direction)
To go back to automatic operation restore
the control signal.
NOTE:
When the manual operation has been used,
the output signal (X) is not accurate until the
actuator reaches its end position.
DIP switch settings ❺
Jumper ①: U/I - Input signal type selector
DIP switches
0-10 V 2-10 V
DIR INV
FAST SLOW
LIN LOG
ACT SMART
Factory settings:
ALL switches are in OFF position!
NOTE:
All combinations of DIP switches are allowed.
All functions that are selected are added
consecutively.
SW 1: Not used
SW 2: Input signal range selector ②
SW 3: Direct or Inverse acting selector ③
- OFF position; the actuator is in direct
acting mode (stem extracts as voltage
increases)
- ON position; the actuator is in inverse
acting mode (stem retracts as voltage
increases)
SW 4: Fast/Slow
- Speed selector ④
SW 5: Not used
SW 6: Not used
SW 7: Linear or equal-percentage flow
through valve selector ❻
- OFF position; the valve position is linear
acc. to the control signal
- ON position; the valve position is equal-
percentage acc. to the control signal.
This relation is adjustable - see
Equal-percentage valve-flow
adjustment section
SW 8: Smart function selector ❼
- OFF position; the actuator does not try
to detect oscillations in the system
- ON position; actuator enables special
anti oscillations algorithm – see Anti
oscillations algorithm section
LED operating mode indicator ❽
Green LED:
• Flashing once every 6 sec. ②
- Stationary mode – actuator reached Y
signal set point
• Flashing once per sec. ③
- Self stroking mode
• Lit ④
- Operating mode – actuator is moving
to Y signal position
Red LED:
• Flashing twice per second ①
- STAND-BY MODE – actuator stopped
and not responding to Y signal -
manual operation enabled
• Lit ④
- Error mode – power supply to low,
initial self positioning time too short
due to too short valve strokes, failure
during self calibration
• Dark / no lights:
- No power supply
