36 CDS Basics During steam production the concentration of minerals in water of the steam generator increases These minerals deposit in the steam generator and build up scale The build up of scale is influenced by the local water hardness and the individual usage of the unit The SCC unit continuously calculates the scale amount inside the steam generator This value is also used for calculating the number of indicated rinse tabs in CareControl Function description At the end of the SC-automatic the steam generator will be filled Solenoid valve Y opens and water flows into the steam generator via the CDS sensor During this filling phase S (CDS Sensor) creates pulses (000 Pulses = l) When the water reaches the level electrode S, the filling will be stopped and the measured number of pulses are stored The unit specific nominal filling volume is stored in the CPU and will be compared with the actual filling volume (calculated from the pulses) The higher the difference between nominal- and actual filling volume, the more scale has built up in the steam generator and therefore also the number of indicated bars in the Care display increases When cleaning the unit regularly as requested, using the CARE tabs the built up of scale in the steam generator will be avoided and the CDS pulses remain constant CPU S B5 F M4 Y S V0 en, SCC_WE - 6 -

37 CareControl The condition of the indication depends on: a: the use of the unit b: the cleaning behaviour of the customer c: the degree of scale in the steam generator (see information CDS) Display Care : very good care - only one green bar visible : medium care - yellow bars are visible : neglected care - red bars are visible The request for Clean+Care has been neglected several times Only regular cleaning will reduce the display to one green bar again Display Clean Actual dirt status : Only green bars visible - no cleaning necessary : Yellow bars visible - CleanJet request will show soon : red bars visible - Cleaning urgently required CleanJet request is dependent on the usage pattern of the unit: - SCC processes - manual modes - cooking programs - duration - temperatures Using any of the Cleanjet programs: Quick, Save, Medium or Strong will reset the bars of the Display Clean to green bar (starting with software version ) CleanJet +Care can only be started when the cabinet temperature is below 50 C ( F) V0 en, SCC_WE
