Figure 24. Example of cooling system
We recommend to equip the cooling system with pressure and flow supervision (FE). The flow
supervision can be connected to digital input function External fault. If the coolant flow is found too
low, the AC drive will be stopped.
The flow supervision and other actuators, e.g. a constant flow valve, are available as options. The
options must be mounted at the junction of the main line and the branching line to the element,
indicated with an asterisk (*) in the figure above.
