production in percentage of total output.
Nominal value: Unit capacity x input signal value.
Actual value: max. Unit capacity x input signal
value x capacity limitation.
Note: If the internal controller is activated only the
actual value is shown.
Under the following conditions the actual value
may differ from the nominal value: upon activation of
the heating power, if capacity limitation is active during
the filling cycle of the steam cylinder.
