<strong>Separator</strong> <strong>Control</strong> <strong>System</strong> <strong>with</strong> <strong>SCU</strong> 8The separator control system assures automatic program control and supervision ofcentrifugal separators. It is configured to meet product and customer requirements,tried-and-tested and ready for immediate operation. The integrated control unit<strong>SCU</strong> 8 controls and monitors the separator as well its entire periphery, includingautomatic valves, pumps and transducers.Features of the <strong>SCU</strong> 8Unit consisting of programmable logic controland operator panelFully graphic 6“ blue-mode displayOperation via touch displayCentral functions via <strong>separate</strong> keysProfibus interface DPSoftware updates via Micro Memory Card(MMC)Easily extendable due to the modular concept<strong>Separator</strong> control systemVisualization of the separator plant (includingprocess diagram of the separator, status ofvalves, pumps, measured data and alarms)Menu-driven user guidancePossibility of checking all relevant separatordata (analog values, timers, limit values,automatic valves, connected pumps, etc.)External signals for controlling the productionand CIP cleaning cycles<strong>SCU</strong> 8 <strong>with</strong> display screens:Main functions of the separator(see upper figure) andtimers (see lower figure)Example of a compact controlcabinet <strong>with</strong> integrated<strong>SCU</strong> 8.

Unit of <strong>Separator</strong> and <strong>Control</strong> <strong>System</strong>Planning and production of the complete functional unit, comprising the separatorand a complete control system from <strong>We</strong>stfalia <strong>Separator</strong>, offers all the benefits of the<strong>We</strong>stfalia <strong>Separator</strong> quality standard ISO 9001:2000 (worldwide!) for our customers.Our control systems are designed in conformity <strong>with</strong>the IEC 60204-1 standard and the requirements of theMachinery Directive.This is to ensure that the separator and control systemare completely tested and that the unit comprising themachine and the control system fulfils the EuropeanCE rules and regulations. In addition, the safetyrequirements for the centrifuge according to EN12547 standard and those specified by the employer’sliability insurance association are fully met. Ourcustomers not only benefit from the safety aspectsbut also from our process engineering know-howgathered over decades.<strong>Control</strong> functionsAll functions of the separator can be controlled andmonitored:Start-up and shut-down of the separatorProduct and CIP programAnalog values (e.g. motor current, bowl speed)Ejection monitoringTurbidity measurementEjection sequences<strong>Control</strong> of the valves for the bowl hydraulicsystem<strong>Control</strong> of the feed and discharge valvesLevel control of the solids pump<strong>Control</strong> of the valve cabinetFlow and pressure regulation3<strong>We</strong>stfalia <strong>Separator</strong>
Possible ConfigurationsThe five control system variants available (<strong>SCU</strong> 8-I, <strong>SCU</strong> 8-MI, <strong>SCU</strong> 8-MO, <strong>SCU</strong> 8-Rand <strong>SCU</strong> 8-ST) are supplied <strong>with</strong> basic functions / equipment, modified according tothe specific application. Thus, the general functionality of the various control systemscan be further extended by special features.<strong>SCU</strong> 8-IFor separators type SA / SB / SC / ES / HS / GS / CS / HF<strong>SCU</strong> 8-RFor separators type RS / ES / OSCombined partial and total ejections<strong>Control</strong> of the product and solids valves / pumpsOption for automatic ejection systems using“sensing liquid” or “turbidity measurement”Partial ejections onlyFilling of the bowl <strong>with</strong> waterMonitoring the clean oil discharge pressure<strong>Control</strong> of the adjustable centripetal pump<strong>SCU</strong> 8-MIFor separators type MS / CN / CS<strong>SCU</strong> 8-STFor <strong>Separator</strong>s type SDPartial ejections only<strong>Control</strong> of product and solids valves / pumpsOptional integration of milk / creamstandardization or in-line fat measurement<strong>SCU</strong> 8-MOFor separators type MS / CN / CSContinuous separationConcentration, clarification and washing ofemulsionsAdjustment of start-up / shut-down water, feed,wash water, overflow and middle phase<strong>Control</strong> of rotary brush strainer, washwater and concentrate pumpCombined partial and total ejectionsProduct displacement prior to a total ejectionOptional integration of cream standardization orin-line fat measurement4<strong>We</strong>stfalia <strong>Separator</strong>
