8.2.1.1 Table layouts
The table is divided into work steps, e.g. feed, and runtime calculations. Also the number of
cleaning cycles per day can be edited.
All work steps are made up of 3 T-steps. The first T-step of a work step is the total duration of
the work step. The two following T-steps specify the activation and deactivation periods within
this work step.
Example work step for aeration: T7 = 240 min is the total duration of aeration. Wíthin these 240
minutes, aeration alternates between ON for 6 min (T8) and OFF for 4 min (T9).

and the new table can then be viewed in the "T-settings" menu. A restart is not necessary.
