Product description
B601D series products are constant pressure water supply controllers specially designed for single-phase motors.
Features
B601D series intelligent constant pressure water supply controller is suitable for automatic control of water pumps. It has the characteristics of high quality, multi-function, low noise and strong versatility.
Automatic sleep without water, better energy saving effect. When there is no water, the unit will run down to the lower limit frequency, test and enter the sleep standby state; resume water and automatically wake up.
Product advantages
1. Automatic sleep when no water consumptions, better energy saving effect. When there is no water consumptions, the unit will run down to the lower frequency limit, test and enter the sleep standby state; resume water and automatically wake up.
2. Automatic and continuous water supply, if outage happens during the operation of the unit, and when the power supply is restored again, the unit can start operation automatically.
3. Single pump application, alternate forward/reverse switching operation to prevent and remove pipeline fouling.
4. Divide a day into multiple periods (intermittent settings can achieve up to 7 periods) for independent pressure and constant pressure control operation. With the water inlet pipe network pressure monitoring function, the operation will be stopped if the inlet water pressure is lower than the set value; the operation will be resumed when the inlet water pressure returns to above the set value.
5. It can be led out from the terminal to the external switch. When the switch is closed, the unit starts and performs constant voltage control operation; the switch is opened to stop operation.
6. It can be led out from the terminal to the external switch for manual/automatic control switching operation, the switch is off, automatic control, constant pressure water supply; the switch is closed, manual control of full speed running water supply.
7. The connection of the two terminals to the common ground respectively controls the rise and fall of the unit frequency. It can be operated under the set pressure range.
8. Automatic alarms such as high water pressure, low water pressure, low water level, sensor open circuit, etc. will stop operation.
9. Automatic alarms such as over-current, over-voltage, under-voltage, phase loss, and overload to stop operation.
