# Adaptive Learn

Navigation: CPA > Pressure > # Adaptive Learn |

A Learn is required for adaptive control algorithm. For further information see Learn.

In the upper half of the adaptive learn window the possible learn settings are listed.

Pressure Limit defines the maximum pressure which during the learn shall be executed. Standard value is sensor full scale. Reduce this value in case of the sensor full scale cannot or should not be reached.

Open Speed defines the speed for opening the valve during learn procedure between position 0% and 50%. Used to protect the pump from excessive gas flow. 1 means full speed (100%).

Bank Selection defines where the learn data is saved after successfully execution. There are four different learn banks available. If the Control Algorithm of the pressure controller is adaptive, the Learn Bank can be selected.

Gas flow recommendation

This tool helps to find a propper learn gas flow.

This window can be opened when clicking the "Calculate" button.

Working point table

By filling in the work point table the learning time can be reduced, only the valve positions that are needed for these work points will be learned.

For the calculation of the recommended gas flow the resulted lowest conductance value of the working point table will be considered. All conductance values which fall below the minimum valve conductance limit are ignored for this calculation (Warning).

Is the working point table empty than recommended gas flow is calculated using the Pressure Limit and the Min Conductance [l/s] (Value is saved in the firmware and can be adjusted by using edit check box).

For more information regarding learn flow calculation see Gasflow calculation for Learn.

The Pressure unit of the working point table can be adjusted under Scaling.

Start Learn

Learn procedure starts by pressing Start Learn button. On the right side the progress bar shows the learn state. If a learning process is currently active, you can terminate it by clicking the 'Terminate Learn' button.

Warnings

Shows the occurred warnings during the learn procedure.

For possible learn warnings see Learn Warnings.

For more information about single learn steps see Execute a learn procedure.
