CE- marking in accordance with
standards: Low Voltage Directive (LVD) 2006/95/EC: EN 60730-1, EN 60730-2-14 EMC Directive 2004/108/EC: EN 61000-6-2, EN 61000-6-3
No tool is required to mount actuator on the valve. Installation of the valve with the actuator is allowed in horizontal position or upwards. Installation downwards is not allowed.
The actuator must not be installed in an explosive atmosphere, at ambient temperature lower than0 °Core Ambient temperature higher than 55 C. It must not be subject to steam jets, water jets or dripping liquid as well.
The actuator may be rotated up to 360° with respect to the valve stem by loosening the retaining ﬁxture. Once the actuator is placed, retighten the ﬁxture.
Electrical connections can be accessed by removing the actuator cover. Two cable gland entries without thread (Ø16 and combined Ø16/ Ø20) are prepared for cable glands. From factory one entry is provided by rubber cable gland and the other entry is prepared for opening.
Cable and cable gland used must not compromise the actuator’s IP rating, and must ensure the connectors are fully strain relieved. Rubber cable gland delivered from factory does not compromise IP rating but it does not provide fully strain relieve according to LVD directive. Please observe local rules and regulations as well.
Jumper/DIP switch setting
U/I – Input signal type selector
– U position; voltage input is selected
– I position; current input is selected
SW 1: Not used
SW 2: Input signal range selector
– OFF position; the input signal is in the range from 0-10 V (voltage input) or from 0-20 mA (current input)
– ON position; the input signal is in the range from 2-10 V (voltage input) or from 4-20 mA (current input)
SW 3: Direct or Inverse acting selector
– OFF position; the actuator is in direct acting mode (stem extracts as voltage increases)
-ON position;the actuator is inverse active mode (stem retracts as voltage increases)
SW 4: Fast/Slow – Speed selector
– OFF position; the actuating speed is 7.5 s/mm
– ON position; the actuating speed is 15 s/mm
SW 5: Not used
SW 6: Not used
SW 7: LIN/MDF – Linear or equal-percentage ﬂow through valve selector
– 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
– 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
Equal-percentage valve-ﬂow adjustment
(SW 7 in position ON)
The actuator has a special valve-ﬂow adjustment feature. Flow can be, by turning
the potentiometer clockwise (CW) or counter clockwise (CCW), variably-adjusted from linear to logarithmic or opposite. For details see
Anti oscillations algorithm
(SW 8 in position ON)
The actuator has special anti oscillations algorithm. In case control signal Y on certain point oscillate (Fig. 2) – looking from time perspective, algorithm starts to lower the ampliﬁcation of the output to the valve. Instead of having static characteristics actuator changes to dynamic characteristics (Fig. 1) – certain output stroke area changes to new slope (decrease ampliﬁcation).
After control signal does not oscillate anymore output to the valve slowly returns back to static characteristics.
Complete the mechanical and electrical installation, set jumper and DIP-switches, then perform the necessary checks and tests:
The unit is now fully commissioned
Automatic self stroking feature
The actuator automatically adapts its stroke to
the valve end positions :
– when power is applied for the ﬁrst time or
– afterwards by pressing the STAND BY/RESET
button for 5 seconds
Testing entire valve stroke length
The actuator can be driven to the fully-open or closed positions (depending on valve type) by connecting SN to terminals 1 or 3.
Led signalling/ Actuator operating modes
LED function indicator
The bi-colour (green/red) LED function indicator is located on the actuator cover. It indicates the operating modes.
Actuator has external STAND BY/RESET button which is located next to LED indicator. By pressing on this button in diﬀerent ways diﬀerent operating modes are initiated:
Manual override is done by means of control knob on actuator housing:
After manual override is not needed:
When the manual override has been used, the output signal (X) is not correct until the actuator reaches its end position.

The actuator must be dismantled and the elements sorted into various material groups before disposal.
