Operation
➜ After the pre-heating time has elapsed or after the step has been skipped, the
filling pressure is automatically regulated to the set process pressure. The following
message appears on the display:
➜
Start automatic mode with
precipitates in the condenser).
Automatic mode
The process time starts when automatic mode is started.
➜ As the evaporation starts, the filling level in the evaporation flask decreases:
– The flask level sensor S4 loses contact with the medium and changes from
high low
to
low
( = start filling time).
➜ As soon as the defined setpoint for the filling time has been reached (
time
expired), the evaporation flask is automatically filled with new educt.

The filling level in the evaporation flask rises again. As soon as the level
sensor S4 detects media contact, the status changes again from

The continuous evaporation process reduces the filling level in the evaporation flask
again:
