Target setpoint is not reached during the optimisation Immediately after the optimisation is finished ( “tunE” does not appear anymore) the actual value is not close to the target setpoint. It is recommendable to reach the target setpoint as exactly as possible at the end of the optimisation to get really good results.

It has to be ascertained as exact as possible for each valve and set to the controller. A bad valve actuating time causes a wrong manipulated variable (see 3.6 actuating time t.P). -
