Diagnostic and troubleshooting
SCC Line from 04-2004
Whenever working on any gas component like:
Gas valve, gas blower and / or changing connected type of gas
a detailed flue gas analysis MUST be done using
adequate CO and CO2measuring equipment!
This shall ONLY be done by trained technicians!
Always check appliance for possible gas leakages!
Isolate the appliance from mains supply
before opening the appliance
When working with chemicals, i.e. aggressive cleaning materials
always wear protective clothing,
goggles, face mask and gloves!
After maintenance / repair the appliance must be checked for electric
safety in accordance with your national, state and local requirements!

Level Control Steam Generator
Center S2 ==> Ground: 2 - 6V AC: water level too low
steam heating must switch OFF
solenoid valve filling ON
Center S2 ==> Ground: 0V AC: water level reached
steam heating can switch ON
solenoid filling switched OFF
Every 2 minutes steam elements will switch off for water level control

Steam Control CM from 04-2004
Intelligent steam control via quenching sensor
1. Filling of interior cabinet
based on time and
temperature control of B1
cabinet sensor
2. After steam saturation
inside cabinet steam will
also fill quenching
chamber
Notes:
3. Depending on the
temperature raise of
quenching sensor B2 the
duration of the next steam
supply is calculated
B2-1: Partial load
B2-2: Full load
4. Interval between steam
supply is depending on the
duration from energizing
steam elements until
reaching set quenching
temperature.
