Figure 3: Start inhibition example 1
Start inhibition example 2:
The maximum number of starts within the Supervising Time has been reached so the Inhib. Strt
Time is initiated. The remaining time Supervising Time – tn is shorter than the Inhib. Strt Time, so
the start inhibition remains for duration equal to Inhib. Strt Time. Therefore, with the default settings
and a tn of 55 mins for example, the inhibition time before a new start is 10 mins.
