Error while turning on and off pump with stateflow depending on physical signal

I am trying to turn on and off a pump depending on the pressure within a hydraulic system. The pressure is measured within the system, feed into a stateflow chart, evaluated and then - depending on the current pressure - a pump is turned on and off through a stateflow output.

However this Setup gives me the error "stateflow chart updates a persistent or state variable while computing outputs, therfore it cannot be used in an algebraic loop."

How can I correct this error?

Thank you!

Adding a delay block in the algebraic Loop should solves the problem.
