Installation
Disposal
Mechanical
The actuator should be mounted with the valve
stem in either horizontal position or pointing
upwards. Use the 57 mm castellated nut
(supplied) to t the actuator to the valve body.
While the actuator is being tted, a 8 mm Allen
key can be used to tighten the pinch screw in the
valve body ring to stop the valve turning.
Allow for necessary clearance for maintenance
purposes.
Electrical
Electrical connections can be accessed by
removing the cover. Two M16 x 1.5 cable entries
are provided. Both entries are provided with a
rubber grommet for use with exible cable. Note
that in order to maintain the enclosure IP rating,
appropriate cable glands must be used.
The actuator must be dismantled and the
elements sorted into various material groups
before disposal.

DIP switch setting
The actuator has a function selection DIP switch
under the removable cover. In particular, if SW6 is
set to ON, the actuator will perform as
3-point actuator.
The switch provides the following functions:
• SW1: U/I - Input signal type selector:
If set to OFF position, voltage input is selected. If
set to ON position, current input is selected.
• SW2: 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).
• SW3: D/I - Direct or inverse acting selector:
If set to OFF position, the actuator is direct acting
(stem lowers as voltage increases). If actuator is
set to ON position the actuator is inverse acting
(stem raises as voltage increases).
• SW4: —/Seq - Normal or sequential mode
selector:
If set to OFF position, the actuator is working
in range 0(2)..10V or 0(4)..20mA. If set to ON
position, the actuator is working in sequential
range; 0(2)..5 (6)V or (0(4)..10 (12)mA) or (5(6)..10V)
or (10(12)..20mA).
• SW6: Prop./3-pnt - Modulating or 3-point
mode selector:
If set to OFF position, the actuator is working
normally according to control signal. If set to
ON position, the actuator is working as 3-point
actuator.
• SW7: LOG/LIN - Equal percentage or linear
ow through valve selector1:
If set to OFF position, the ow through valve is
equal percentage. If set to ON position, the he
ow through valve is linear according to control
signal.
• SW8: 100% KVS/Reduced KVS - Flow reduction
through valve selector1:
If set to OFF position, the ow through valve is
not reduced. If set to ON position, the he ow
through valve reduced by half of increment
standard KVS values (exsample: valve with KVS 16
and SW8 set to ON – maximum ow through the
velve is KVS13 (meiidle between standard KVS 16
and KVS 10).

NOTE: To be used only in comb ination with valves with equa l
percentage characteristic.
• SW9: Reset:
Changing this switch position will cause the
actuator to go through a self stroking cycle.
DEN-SMT/SI
• SW5: 0..5V/5...10V - Input signal range in
sequential mode:
If set to OFF position, the actuator is working in
sequential range 0(2)..5 (6)V or 0(4)..10 (12)mA.
If set to ON position, the actuator is working in
sequential range; 5(6)..10V or 10(12)..20mA.

Automatic self stroking feature
When power is rst applied, the actuator will
automatically adjust to the length of the valve
stroke. Subsequently, the self stroking feature
can be re-initialised by changing position of SW9.
DIP 6 = OFF
Diagnostic LED
The red diagnostic LED is located on the pcb
under the cover. It provides indication of three
operational states:
• Actuator Healthy (Permanently ON),
• Self Stroking (Flashes once per second),
• Error (Flashes 3 times per second - seek
technical assistance).

CommissioningCommissioning / testing feature
Complete the mechanical and electrical
installation and perform the necessary checks
and tests:
The actuator can be driven to the fully open or
closed positions (depending on valve type) by
connecting SN to terminals 1 or 3.
• Isolate control medium. (e.g. self stroking
in a steam application without suitable
mechanical isolation could cause a hazard).
• Apply the power. Note that the actuator will
now perform the self stroking function.
• 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.
Manual override
(1)Remove grommets (2)Push (3)Turn
The manual override is applied by rotating the
8 mm Allen key (not supplied) to the required
position. Observe the direction of rotation
symbol.
• Disconnect power
• Remove grommets and push the button
• Adjust valve position using an 8 mm Allen key
• Set valve to closed position
• Restore power
Note:
Actuator will restore position required by
Y signal.
