Installation Mechanical
The actuator should be mounted with the valve
stem (use a 4 mm Allen key - not supplied) in
either horizontal position or pointing upwards.
Use a M8/SW13 key (not supplied) to fit the
actuator to the valve body. Allow for necessary
clearance for maintenance purposes.

the position of valve opening degree after selfadjustment.
Arrange proper valve insulation in order to avoid
direct heat transfer toward actuator.
Electrical
Electrical connections can be accessed by
removing the cover.
Two M16 × 1.5 cable entries are provided. Both
entries are provided with a rubber grommet
for use with flexible cable. Note that in order to
maintain the enclosure IP rating, appropriate
cable glands must be used.

The actuator has a selection of DIP switches
under the removable cover.
The switch provides the following functions:
DIP1: U/I - Input signal type selector:
• If set to OFF position, input signal Y is set to
voltage (Y).
If set to ON position, input signal Y is set to be
current (mA).
DIP2: 0/2 - Input signal range selector:
• If set to OFF position, the input signal is in the
range from 2 V to 10 V (voltage input) or from
4 mA to 20 mA (current input). If set to ON
position, the input signal is in the range from
0 V to 10 V (voltage input) or from 0 mA to 20
mA (current input).
DIP3: D/I - Direct or inverse acting selector:
• If set to OFF position, the actuator is direct
acting (actuator’s stem extends by voltage
increase). If actuator is set to ON position the
actuator is inverse acting (actuator’s stem
retracts by voltage increase).
DIP4: —/Seq - Normal or sequential mode
selector:
• Two actuators can be set to work parallel with
one control signal. If the SEQUENTIAL is set
than an actuator responds to split control
signal (see 0(2) V … 5(6 V) / 5(6) V … 10 V).
NOTE: This comb ination works in combina tion with DIP5: 0(2) V
… 5(6 V) / 5(6) V … 10 V

DIP switch setting
(continuous)
DIP5: 0-5 V/5-10 V - Input signal range in
sequential mode:
• This function is available if
DIP4:---/Sequential is set to ON, otherwise
the actuator operates in full controll range
(0(2)-10V or 0(4)-20mA).
• When DIP5 is set to Off the actuator will
match the range of the control signal:
2 … 6 V (when DIP1 and DIP2 are set to Off)
0 … 5 V (when DIP1 is set to Off and DIP2 is set to ON)
4 … 12 mA (when DI P1 is set to ON and DIP2 is set to Off)
0 … 10 mA (when DIP1 & DIP2 are set to ON)
• When DIP5 is set to ON the actuator will
match the range of the control signal:
6 … 10 V (when DIP1 and DIP2 are set to Off)
5 … 10 V (when DIP1 is set to Off and DIP2 is set to ON)
12 … 20 mA (when DI P1 is set to ON and DIP2 is set to Off)
10 … 20 mA (when DIP1 & DIP2 are set to ON)
DIP7: LOG/LIN - Equal percentage or linear flow
through valve selector1:
• Characteristic of valve is unchanged by
factory setting (DIP 7 OFF).
Danfoss valves as VF, VFS and VFM that
are suitable to operate with actuator
have logarithmic (equal percentage) flow
characteristic. By setting switch to LIN flow
the characteristic of motorized valve will
be affected. Combination of actuator and
valve will work together as valve with LINEAR
characteristic.
DIP8: 100 % KVS/Reduced KVS - Flow reduction
through valve selector 1):
• If set to OFF position, the flow through valve is
not reduced. If set to ON position, the he flow
through valve reduced by half of increment
standard KVS values (example: valve with
KVS 16 and DIP8 set to ON – maximum flow
through the valve is KVS13 (middle between
standard KVS 16 and KVS 10).
1)
NOTE: To be used only in com bination with valves with equ al
percentage characteristic
DIP9: Reset:
• Changing this switch position will cause the
actuator to go through a self-adjustment
procedure.
DIP6: Prop./3-pnt - Modulating or 3-point
mode selector:
Actuator can operate in modulating (DIP 6
to OFF) or in “simple” 3-point mode, if the
3-point function is selected (DIP 6 to ON).
Modulating mode; DIP 6 set to OFF
(factorysetting)
• After the actuator has been connected to
power supply, the actuator will start the
self-adjustment procedure. The indicator LED
flashes until self-adjustment is finished.
• Actuator’s stem will run to its totally extended
or retracted position by bridging SN signal
to terminals 1 or 3 and will remain in this
positron as long as potential is present.
It is not allowed to bridge SP to terminal 1
or 3 when DIP 6 is set to OFF .
3-point mode; DIP 6 set to On
Look carefully wiring diagrams as wiring is
different for controllers with triacs output
(ECL) in comparison to controllers with
relay output.
• Connect SN (Neutral) and power supply
(24Vac) via controller to terminals 1 or 3.
• Return signal X (depends on DIP 2, 3, 4 & 5) is
possible if connected power supply to SP and
SN.

Automatic self-adjustment procedure
The actuator will automatically adjust to the
stroke of the valve, when power supply is first
time connected to the actuator or when the
actuator is reset.
The LED indicator flashes until self-adjustment
is finished. The duration depends on the spindle
travel and will normally last a few minutes.
To restart self-adjustment, change the position of
RESET switch (DIP9).
If the supply voltage is switched off or falls below
80% in more than 0.1s, the current valve position
will be stored in the memory also after a power
supply cut-out.
Signal on terminals 1 or 3 have priority
toward Y input signal.
Diagnostic LED
The red diagnostic LED is located on the pcb
under the cover. It provides indication of
following operational states:
Constant light
- normal operation
No light
- no operation or no power supply
Intermittent light (1 Hz)
- self-adjusting-mode
Intermittent light (3 Hz):
- power supply too low
- insufficient valve stroke (<20 s)
- end-position cannot be reached.

Complete the mechanical and electrical
installation and perform the necessary checks
and tests:
• Isolate control medium. (e.g. self-adjustment
in a steam application without suitable
mechanical isolation could cause a hazard).
• Apply the power. Note that the actuator will
now perform the self-adjustment procedure.
• Apply the appropriate control signal and
check the valve stem direction is correct for
the application.
• Ensure that the actuator drives the valve over
its full stroke, by applying the appropriate
control signal. This action will set the valve
stroke length.
The unit is now fully commissioned.
The actuator can be driven to the fully open or
closed positions (depending on valve type) by
connecting SN to terminals 1 or 3.
4 mm Allen key (not supplied) to the required
position. Observe the direction of the rotation
symbol.
• Disconnect power supply
• Adjust valve position using an Allen key
• Set valve to closed position
• Restore power supply
If manual override has been used then X and Y
signal are not correct until the actuator reaches
its end position. If this is not accepted reset the
actuator, or apply accessory active return signal
kit.
Usage of electrical drill machine is not
allowed.
