Rational SCC_WE - Water level control steam generator SCC_WE

V02 en, SCC_WE - 16 -
Center level electrode S2 => Ground: 2 - 6V AC:
water level too low
steam heating must switch OFF
solenoid valve filling Y1 ON
Center level electrode S2 => Ground: 0V AC:
water level reached
steam heating can switch ON
solenoid valve filling Y1 switched OFF
Level electrode can be measured at X12: 1-4
The level electrode is equipped with two side elec-
trodes to ensure safe water level recognition even
when the center level electrode is scaled. These
side electrodes compensate for the build up of scale.
Permanent water level control;
Maximum continuous steam time: 2 Minutes,
Property of connected water:
Conductivity must be above 50µS/cm;
St.Gen. empty: ca. 2 - 6V AC
St.Gen. full: 0V
SV Filling on 230V
