2Solutions always by your side2 labels: total solutions for your applicationsThe automation of industrial machinery and equipment addresses human and financialchallenges of security and productivity.Our leadership in the nuclear market with more than 120 reactors installed worldwide and ourcontinuous experience from the 70’s have shaped our expertise and our control of processes.Our understanding of industrial processes drives the design and manufacturing of our electricalactuators. Our vision of controls furthers the appearance of solutions fully adapted to markets’evolutions and to our customers’ budgetary and technological requirements.That is why our electromechanical profile has developed into an expertise in the management ofevermore complex systems.BERNARD CONTROLS propose 2 labels which federate well different ranges of actuator solutions:SIMPLE, STURDY, ECONOMICALIn order to fulfill the need for actuatorsthat are both simple and sturdy, we havecreated the FIRST BC label.This label guarantees quality and security toinstallations’ electric actuation solutions in thecase of moderate environmentaland operational constraints.DEDICATED SOLUTIONSTo fulfill the need for reliable, highperformance and innovative actuators,we have defined the BC PREMIUM label.The BC PREMIUM label is the guarantee ofquality and security for installations’ actuationin the case of demanding environmentaland operational constraints.ContentsSolution always by your sideInnovation always by your sideA dedicated guide to define yourmodel of actuatorFocus on Operation 23 46Range Overview withDuty and Modulating Classification Focus onBC Technologies & Services Specifications 141618

6Focus on OperationActuator Duty & Modulating ClassificationOperation is a decisive step in your electric actuator selection.Looking carefully at your process requirement will make the difference.Actuator DutyThe EN 15714-2 Standard defines 4 actuator duties with basic design requirements per movement tooperate the valve: part-turn, multi-turn and linear.Class AClass BClass CClass DOn-OffInching / PositioningModulatingContinuous modulatingThe actuator is required todrive the valve through itsentire travel from thefully open position tothe fully closed positionor vice-versa.The actuator is requiredto occasionally drivethe valve to anyposition.The actuator is requiredto frequently drive thevalve to any positionbetween fully open andfully closed.The actuator is requiredto continuously drivethe valve to any positionbetween fully open andfully closed.Relying on its experience and on years of customers’ feedbacks, BERNARD CONTROLS considers thatthese 4 types of operation must be specified with key criteria in order to define theunique appropriate solution to the process requirement of each customer. On-Off & Positioning: Increase ENDURANCEConsidering On-Off applications (Class A) and Inching/Positioning applications (Class B), processrequirements imply to set ENDURANCE as the decisive criteria. Number of cycles, i.e. life time of theactuator, will make the difference for the customer and his application. Modulating & Continuous Modulating: Improve PERFORMANCEModulating and Continuous Modulating applications require specific expertise to define the mostappropriate solution. For many years BERNARD CONTROLS has been a leader in electric actuation and aforerunner in modulating technology. Our modulating classification (Class III which complies with EN15714-2Modulating and Classes II & I which comply with EN15714-2 Continuous modulating) is now well-knownfrom our customers and has, in fact, inspired the EN 15714-2 Standard.Duty PERFORMANCE is the main criterion to fully address modulating process requirements, but needs tobe specified and completed with additional performance criteria.BERNARD CONTROLS sets 4 additional performance criteria to EN15714-2 basic design requirements:RESOLUTION *Response Time*Dead BandThese criteria determine the efficiency of the modulating process.*Linearity*

DEAD BAND: the range through which an input signal may vary, upon reversal of direction, without triggering any observable change in theposition of the valve. REPONSE TIME: the time needed by the actuator to reach position following an input signal change. LINEARITY: the percentage of change in input signal must approximate the percentage of the change at the output of the actuator.Specification Guide

16FOCUS ONBC Technologies & ServicesBERNARD CONTROLS technologies are the result of years of return on experienceand customer feedbacks. These have led to actuators with heavy-duty mechanicaldesign and increased security through performing electronics. Gear transmission systemHigh transmission efficiency & self-locking capacity Electric actuators generallyuse a worm drive becauseof its advantages of highdrive ratio and self-locking.The mechanical design ofBC actuators combinesworm drive and hightransmission efficiencyplanetary, in order toreduce the motor’s powerconsumption, optimizehandwheel transmissionand to be self-locking atall speed.T ravel limitation systems User-friendly & reliable travel limitation system Bernard Controls proposesa patented cam block system,which offers the followingadvantages: Fast & easy setting Vibration proof Precise indication Torque limiters User-friendly & reliable torquelimitation system Bernard Controls design of torque limiters is usingproven technology offering: Full reliability Ease of adjustment High precision & repeatability Manual override asy maintenance with BC manual overrideEtechnology Depending on the markets and types of facilities,the features of emergency manual control key functions of the actuator - can be verydifferent. However, several features have a primesignificance: it must be possible to operate thehandwheel at any time & the number of turns onthe handwheel must not be too high. S4 Motor Duty cycle The only representative duty cyclefor electric actuator operation The IEC 34 standard defines the electric motors’standard duty cycles. S2 duty rating is short timeduty: motors adapt to constant load. Temperaturerises fast during the operation and quickly reachesits limit. Motor needs long stop for total coolingbetween each start.S4 duty cycle is intermittent duty with starting.Motors start with a large output torque.Temperature slowly decreases once operatingtorque has been reached. Therefore, the motor canbe restarted shortly after shutdown.BC has chosen the S4 duty rating because it isthe most representative duty cycle foractuators operations.S2S4SHORT TIME DUTYiINTERMITTENT DUTY WITH STARTINGiNtD NMRIEC 34 S2 & S4 Motor Duty Cyclest
17 INTELLI control ESDI ncreased security on site ESD (Emergency Shut Down) is a remote emergencycontrol signal with priority over all other commands inorder to protect the pipeline and equipment fromdamage. Depending upon the valve operation, ESDcan be configured as an Open, Close or Stopcommand. SIL DesignI NTELLI is an intuitive and intelligent integratedcontrol which offers key benefits to end users: Non-intrusive settings Intuitive interface with local LCD displayand easy-to-use menu Accurate information with absolute sensors,which constantly measure the position andtorque of the valve Increased security with constant selfmonitoring, ESD, Partial Stroke Test (PST),Alarms indication, signaling continuity. Preventive maintenance: INTELLI continuously monitors its components as wellas the actuator status and measures someimportant valve parameters. It provides userswith a great deal of information to help withsystem diagnosis, aid in scheduling their valvespreventative maintenance and maximizeprocess availability by reducing maintenancedowntime. INTELLI permanently monitorsthe required torque necessary to operate thevalve, memorizing these torque valuesgenerated during the last open and closeoperations. Infra-red/Bluetooth communication with PCand tablet via INTELLISOFT software to collectdata, implement settings/configuration.) Open fieldbus systemsE asy site management BC chooses the «open» fieldbus system for all itsfieldbus solutions.Our actuators can be connected to most of thestandard fieldbus available on the market:PROFIBUS DP, FOUNDATION FIELDBUS, MODBUSRTU, HART and other fieldbus on demand.For more security, redundant fieldbus ensurescontinuous operation, even in case of a bus linedisruption.M ore than safety commands, SIL certified signalingfunctionsT he SIL - Safety Integrity Level - is a measure of thelevel of security provided by a technical measurementof a risk control system (cf. IEC 61508 & 61511standards).

The actuator is required to continuously drive the valve to any position between fully open and fully closed. The actuator is required to occasionally drive the valve to any position. The EN 15714-2 Standard defines 4 actuator duties with basic design requirements per movement to operate the valve: part-turn, multi-turn and linear.
