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: 0-10V/2-10V
- 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: LIN/LOG - 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:
• 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:
• 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
