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.
