Abstract

The water supply system consists of the function of controlling the pump and which consists of equipment A number of inverters with their own protection devices and a number of variable speed pumps are connected to such inverter devices in a 11-relationship. The pump control eliminates the need for a separately prepared control circuit. It consists of a built-in microcomputer and requires only an inverter device. Only two Such a system can be perfectly matched and therefore Can insure a high level of reliability When one of the two inverter devices is stopped The pump controller's restart path will send a restart command in order to make the Therefore, when the protection cause, another inverter device is restarted to the stopped inverter device. Of the stopped inverter device has been removed at the time of giving the restart command. Other inverter devices The stopped inverter device will also be restarted, which can reduce the chance of the inverter equipment being completely stopped:
