The HE 5750 for large installations is a Master-Slave system. According to the size of the plant the associated slaves required are connected to the master controller per field bus. In each case one slave controller is assigned to one filter chamber, locally and technically. This flexible concept adapts itself to any required number of filter chambers and valves. The system can be configured customer-specific and pre-assembled up to the valve connector. That reduces the commissioning times and costs considerably. The support is simplified through remote diagnostics and maintenance by means of modem- or internet connection (Remote-Access).
