1.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.
2. Function description
At the end of the SC-automatic the steam generator will be filled. Solenoid valve Y1 opens and
water flows into the steam generator via the CDS sensor. During this filling phase S11 (CDS Sen-
sor) creates pulses (1000 Pulses = 1l). When the water reaches the level electrode S2, 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.
