This issue is part of #1352 and tackles the PumpsPolynomialBased.

Error in model:  AixLib.Fluid.Movers.PumpsPolynomialBased.Examples.PumpHeadControlled 
Simulation execution failed for model: AixLib.Fluid.Movers.PumpsPolynomialBased.Examples.PumpHeadControlled
assert            | warning | The following assertion has been violated during initialization at time 0.000000
|                 | |       | pump.deMultiplex3_1.u[1] >= pump.deMultiplex3_1.u[2]
assert            | error   | Input signals are not consistent: limit1 < limit2
assert            | error   | Failed to solve the initialization problem with global homotopy with equidistant step size.
assert            | debug   | Unable to solve initialization problem.
assert            | info    | simulation terminated by an assertion at initialization

Warning: The model contains alias variables with redundant start and/or conflicting nominal values. It is recommended to resolve the conflicts, because otherwise the system could be hard to solve. To print the conflicting alias sets and the chosen candidates please use -d=aliasConflicts.

[skip-ci] Delete StateGraphs as they lead to problems with OpenModelica.

Also they are incorrect, since the head is delayed by 60 seconds but the on-Signal of the pump is not delayed.
