If the temperature displayed in Pr 7.04 exceeds the trip threshold for the parameter an Oht2 trip is initiated. This trip can only be reset if the parameter
that has caused the trip falls below the trip reset level. If the temperature exceeds the alarm level, a "hot" alarm is displayed. If the temperature for any
of these monitoring points is outside the range -20
initiated (HF27), details are given in the following table.
