3.2 Simultaneous mode
If simultaneous mode is selected, the action to increase the minimum HPV valve set point is performed in the
same way as in sequential mode, and is configured on screen Eeab28.
The action to increase the gas cooler fan set point, on the other hand, is calculated automatically based on
the following diagram:
Increase the minimum

The new gas cooler set point will respect the limits defined
on screen Dab02.
To avoid abrupt variations to the set point, a maximum
decrease time can be specified in relation to application of
the maximum allowed offset.
