motor controller feature
1. control method: pressure, temperature, time,differential pressure
2. fire pump start-up frequency can be used directly from the start, lotus step-down start, Y - train step-down start, thyristor soft start-up control, frequency conversion control, constant pressure to meet different requirements.
3. have overpressure,undervoltage, short-circuit, lack of water shortage, such fault alarm protection function.
4. in accordance with customer requirements it can installs the dual power switch function, or the single dual-supply mutual shots, Lord, for power can be manually or automatically when the power switch, the power supply, alternate power auto-cast, main power was restored, standby power automatic exit.
5. equipment can be added according to user requirement of building control (BA) interface, and computer networking, computer terminals, centralized monitoring.
