NOTE:
For details on the choice of Level Wet and Level Dry, see Section 10.6.1.
10.3 Setting P & I Values
P & I values are numbers that determine how the fermentor responds to changing
growth conditions and new setpoints. These are listed in each loop’s
GAUGE
screen.
You may need to modify P&I values to suit your particular process. To do so, press
inside the Proportional & Integral edit boxes, each time entering the desired value
using the popup keypad.
#
NOTE:
If you change P&I values, you can return to the original settings at any
time by pressing the Factory Default button (see Figure 13).
10.4 Loop Setpoints
The setpoint is the value you want each loop to attain. When the loop control mode is
AUTO , the fermentor will automatically make appropriate adjustments to maintain the
value at the setpoint.
