Ventilator control
Simple ventilator controls can be developed with the temperature sensor which is built into the Prophi® and a ventilator. A relay output or the alarm relay is used for controlling the ventilators. The upper/lower temperature limit can be programmed for this feature.
Excess temperature shutdown
Connected capacitor steps can be disconnected with the excess temperature shutdown function in order to reduce the temperature inside the switchboard cabinet and to protect the capacitors. The upper/lower limit temperature and pause time can be set.
Connection example power factor controller with L2-L3 measurement, 12 relay outputs, target cos-phi changeover, alarm output.
