1 CENTORK ELECTRIC ACTUATORS: INTRODUCTION
The electric actuator is a device designed to be coupled to a general purpose industrial valve, to carry
out its movement. The movement is stopped by limit switching or by torque switching. Other applications
should be consulted CENTORK before. CENTORK is not liable for any possible damages resulting from
use in other than designated applications. Such risk lies entirely on the user.
2 SAFETY INSTRUCTIONS
The scope of this manual is to enable a competent user to install, operate, adjust and inspect a
CENTORK electric actuator. These instructions must be observed, otherwise a safe operation of the
actuator in no longer warrantee.
When handling electric equipment, the health and safety standards (EN 60.204, 73/23/EEC
directives) and any other national legislation applicable must be observed.
As electric device, during electrical operation certain parts inevitably carry lethal
voltages and currents (ELECTRICAL RISKS).
Works on the electrical system or equipment must only be carried out by a skilled electrician
himself or by specially instructed personnel, in accordance with the applicable electrical
engineering rules, health and safety Directives and any other national legislation applicable.
Electric actuators are powerful apparatus. A negligence handling might cause severe
damages to valves, people, and actuator as well. Under no circumstances should
any modification or alteration be carried out on the actuator as this could very well
invalidate the conditions which the device was designed.
Under operation, motor enclosure surfaces can reach high temperatures (up to
100ºC). Protection measures should be taken into acount in order to prevent people
and goods from it.

3 TRANSPORT AND STORAGE
3.1 Transport
− CENTORK electric actuators must be transported in sturdy packing. During transport measures
should be adopt in order to prevent impacts, hits. CENTORK delivers its actuators ex-work.
− Hits or impacts against wall, surfaces or objects might cause severe damage on Electric actuator.
In this cases, after such events, a technical inspection must be done by CENTORK technicians.
− Do not attach to the handwheel ropes or hooks to lift by hoist.
− The valve-actuator unit can NOT be lifted/manipulated employing any lifting point of the actuator;
Actuator has beend designed and sized in order to motorize industrial valves, and withstand the
forces and torque required.
− Each Actuator is delivered with a set of technical documentation (User manual, datasheet,
diagrams…) which has to be carefully stored.
3.2 Storage and commissioning
− Store in a clean, cool, dry and ventilated place. For other storage conditions or, and long
time periods (More than 5 months) contact to manufacturer.
− Check that electrical connection cover and switching and signalling unit cover and are correctly
closed ant tight.
− Cable entries on electrical connection cover must be sealed. Protection plug
supplied by CENTORK are only adequate for storing in dry and ventilated
places, for short period of time. In other conditions protection plug must be
replaced with metallic plug sealed with PTFE tape.
− Do not store the actuator directly on the ground!
− Cover it to protect it from dust and dirt. Cover the machined parts with
suitable protection against corrosion.
− Do not handle it by picking it up by the handwheel.
− Just when commissioning, CENTORK recommend a visual inspection in order to detect any
anomaly caused during the transport, and during the storage as well. Checking should
include a visual inspection of electric compartment, and switching and signalling unit .
− Each Actuator is delivered with a set of technical documentation (User manual, datasheet,
diagrams…) which has to be carefully stored.
− For further details, consult the technical sheet ‘Conditions for Transport and Storage’.

4 CONDITIONS OF SERVICE FOR ELECTRIC ACTUATORS
4.1 Electric actuator: Main description and purpose
− Electric actuator is an apparatus or device formed by a
electric motor, coupled to a main gearbox unit, which
transmits motion and torque to valves.
− Power supply and controls elements (transformer, relays,
leds, electronic boards…) are included in the Centronik
unit. Centronik unit has CPU microprocessor and
electronic boards: Electric actuator is operated and
controlled by means of these electronic and electric device
of the centronik unit, being supplyied with main power.
− Electric actuator can be controlled in LOCAL mode from
the centronik front panel or in REMOTE mode.
− Electric actuators actuators are provided with a
declutchable manual override system in order to operate
manually in case of emergency or fail of power supply.
− Electric actuator can be coupled directly to valve,
− The electric actuator is a device designed to be coupled to
a general purpose industrial valve, to carry out its
movement. The movement is stopped by limit switching or
by torque (thrust) switching. Other applications should be
consulted CENTORK before. CENTORK is not liable for
any possible damages resulting from use in other than
designated applications. Such risk lies entirely on the user.
4.2 Operation modes: OFF, LOCAL and REMOTE mode
Electric actuator can be controlled by the control station (REMOTE mode) and at the local control
(LOCAL mode). Centronik unit is equipped with local controls. The lockable selector switch
LOCAL/OFF/REMOTE allows the operation mode to be set.
4.2.1 OFF mode.
− In this operation mode, the actuator remains connected but does not responds to any order from the
front panel or from the remote control. The front panel control indicates only the power supply status
(led 5).
4.2.2 LOCAL mode.
− With the push buttons OPEN-CLOSE-STOP located on the centronik front panel, the actuator is
operated locally. 5 indication lights (LEDs) show the actuator status from the centronik front panel
(chapter 9.12.2).
− Push buttons are self-retaining type: Once the push button has been pressed , its order or action is
generated, and it remains “active” until a new order or command is generated, or any operation
event takes place such us a limit switch or torque signal, an anomaly action or any centronik function
or event. It is NOT necessary to keep “pressing” the pushbutton or the remote input.

4.2.3 REMOTE mode.
Electric actuator with ON/OFF duty control:
− Electric actuator can be controlled by the control
station (REMOTE) with the commands OPEN-CLOSE-
STOP (self- retaining) or OPEN-CLOSE as option
(push to run operation), or with Fieldbus
communication.
− ON/OFF duty control means open loop control.
− With self-retaining operation, the actuator continues to
run as long as the STOP command from the control
system (digital input) is not being generated, or any
centronik operation condition takes place.
− With push to run operation (Inching mode) the actuator
continues to run as long as this command from the
control system (digital input) remains. It is necessary
to keep “pressing” the pushbutton or the remote input.
− Electronic position transmitter (0-4/20mA, 0-2/10V or
resistive value) can be employed, as option, which in
order to provide the real valve position indication.
Electric actuator with Modulating duty control:
− Electric actuator is equipped with an electronic integral
positioner which automatically positions the valve in
accordance with the analog input control signal (4/20mA
current signal and voltage signal as option) or the input
control from Fieldbus communication.
− Modulating duty control means close loop control. The
modulating duty registers and compares the analog input
control and the actual position value (Feedback signa
given by actuator position transmitter). The electric
actuator runs to OPEN or CLOSE direction, according to
the deviation detected.
− The modulationg behaviour is stabilised by determining
inner (internal) and outer (external) dead bands, rest
time and therefore the wear of valve and actuator can
be reduced.
4.3 Temperature range
CENTORK Electric actuators work in a temperature range from -20ºC to +65ºC.
4.4 Actuator and motor duty service
Electric actuator has been designed for valve motorization which requires ON-OFF and inching or
modulating duty service.
− ON-OFF duty service: Electric actuator has been designed as S2 20-50% Max 30min duty cycle at
nominal torque, according to IEC standards: Nominal torque is rated to 50% of max tripping torque
(100%), value marked on actuator nameplates. Higher nominal torques can reduce the actuator’s
service life and S2 duty cycle.
− Inching or modulating duty service: Electric actuators has been designed as S4 30-50%, at 1.200-
300 starts per hour, at nominal torque. Nominal torque is rated to 50% of max tripping torque
(100%), value marked on actuator nameplates. Higher nominal torques can reduce the actuator’s
service life and S4 duty cycle conditions.

5 ABOUT PROFIBUS-DP
Nowadays information technology (IT) is increasingly determining growth in the world of automation.
The communications capability of devices and continuous, transparent information routes are
indispensable components of future-oriented automation concepts. ProfiBus represents one of the
best-known industrial FieldBus protocols from Europe. ProfiBus can be used in a very wide range of
applications as a multi-application communications link for industrial devices, as well as cell-level
communication.
Standardized as EN50.170, ensures manufacturers and users investments and guarantees the
independence of the manufacturer.
These user manual does not pretend to provide a detailed introduction to PROFIBUS-DP. If more
detailed information were needed, please refer to specialized bibliography.
5.1 General description
ProfiBus utilizes a non-powered two-wire (RS485) network. A ProfiBus Network may have up to 126
nodes. It can transfer a maximum of 244 bytes data per node per cycle. Communication (baud) rates
are selectable but overall end-to-end network distance varies with speed. Maximum Communication
(baud) rate is 12Mbps with a maximum distance of 100M (328ft). The maximum distance is 1200M
(3936 ft) at 93.75Kbps without repeaters.
ProfiBus connects to a wide variety of field devices including discrete and analog I/O, drives, robots,
HMI/MMI products, pneumatic valves, actuators, transducers, and flow measuring equipment.
The data flows by the field cyclically. The Master devices of the fieldbus, are the ones to control the
data flow cycles in the fieldbus. They are capable of sending messages without an external request.
The Slave devices are those that only can listen to the messages sent by a master and answer that
message if was sent to its address. CENTRONIK PROFIBUS-DP actuators can only be slave devices.
Typical slave devices are input/output devices, actuators and plant sensors. They never have bus
access, they only acknowledge or reply messages coming from a master.
5.2 Network overview
The media for the fieldbus is a shielded copper cable consisting of a twisted pair. The baudrate for the
bus is between 9.6 Kbaud to max. 12 Mbaud. The PROFIBUS-DP network can consist of 126 nodes
and the total amount of data for PROFIBUS-DP are 244 Byte out per node and 244 Byte in per node.
NOTE: Node No. 126 is only used for commissioning purposes and should not be used to exchange
user data.

7 MOUNTING TO THE VALVE
7.1 Pre-Installation Inspection
− Verify the actuators nameplate to insure correct model number, torque, operating speed, voltage and
enclosure type before installation or use.
− It is important to verify that the output torque of the actuator is appropriate for the torque
requirements of the valve and that the actuator duty cycle is appropriate of the intended application
7.2 ACTUATOR MOUNTING
− Do not lift the actuator by the handwheel. Do not attach to the handwheel ropes or hooks to
lift by hoist.
− The actuator may be mounted in any position
− The CENTORK quarter turn electric actuator Series are supplied with a female drive output.
ISO5211. Bolt patterns are provided for actuator mounting. The actuator drive bush is removable
for ease of machining (except for 480.006). To remove the drive bush, just take out the 2 fixing
screws.
− It is mandatory that the actuator be firmly secured to a sturdy mounting bracket or directly mounted
to the valve’s ISO mounting pad. High tensile bolts or studs with spring locking washers must be
used.
− The valve output shaft must be inline with the actuator output drive to avoid side-loading the shaft.
To avoid any backlash no flexibility in the mounting bracket or mounting should be allowed.
− Reserve the space for maintenance routines and tasks.

9.1 Handwheel and Declutching
Quarter turn electric actuators are provided with a declutchable manual override system. The
override engagement lever returns automatically to auto position when the actuator is operated
electrically.
For 480.006 models
− In order to manually operate the actuator, take the key
wrench tool (See picture)
− Key wrench tool has to be coupled to square shaft of the
actuator in order to operate it.
− Turn clockwise to close and anti-clockwise to open.
For 480.010 models and higher
− In order to manually operate the actuator, pull the manual override
− Engagement lever towards the handwheel until it remains in position.
− Turn the handwheel until the valve reaches the required position
− Turn clockwise to close and anti-clockwise to open
