Water level control steam generator - SC Automatic

SCC_WE
CDS sensor, water flow meter
Check water level of steam generator in diagnostic mode:
Level electrode S2 = 0, water level too low
steam heating must switch OFF, solenoid valve filling Y1 ON
Level electrode S2 = 1, water level reached
steam heating can switch ON, solenoid valve filling Y1 switched OFF
The level electrode is equipped with two side electrodes 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;
SC Automatic
Normally the unit will pump the water from the steam generator when it is switched on in the morning.
This automatic water changing is called SC Automatic.
In case the unit is permanently used and can not cool down, this SC Automatic can also happen during the day when
the door is kept open for longer than 2 minutes.
During the production of steam, the concentration of minerals inside the steam generator will increase over time.
These minerals settle on the heating elements and heat exchanger as well as the interior steam generator walls.
In order to reduce this effect the steam generator will be pumped off and flushed regularly depending on the dura-
tion of steam production. This process needs approximately 45 seconds.
After emptying the steam generator it will be filled automatically with fresh water.
The SC pump can be set to continuous or puls operation (ref. Service mode).
In case the water can not be pumped off (M4 faulty or blocked, M4 hose is blocked) the unit will show a „Ser-
vice 10" error. This can be cancelled (arrow back) and cooking can continue.
Please refer to fault tree!
SCC: Use Rinse / dump steam generator to clear error after repair
CMP: Use ESG in additional functions to clear after repair
