Vacon recommends to equip the cooling system with pressure and flow supervision (FE). The flow
supervision can be connected to digital input function

The flow supervision and other actuators, e.g. a constant flow valve, are available as options. The
options shall be mounted at the junction of the main line and the branching line to the element,
