Total pressure drop larger than 20 bar

The error message:

Open

This fault occurs during the ‘optimise system components’- calculation steps.

Meaning:

This fault occurs if the calculated pressure drop exceeds 20 bar (2000 kPa), as this is set as a maximum in the software.

How to solve this error:

Check if all the pressure drops in the system are filled in correctly.

You can easily check this by clicking on the pump and using ‘Ctrl+e’. This will show the path of most resistance. Follow this path and use dynamic label to analyse the pressure drops over different components. Compare these to the actual pressure drop and correct the wrong ones and recalculate.

It may also be that there are pipes locked on a size which is significantly to small, causing their pressure drop to be to large.
