 Sleep pump control functions: Support flexible sleep mode, the small sleep pump
will start automatically at sleep state in order to maintain sleep pressure effectively.
Once meeting the wake-up conditions, the system will come out of hibernation
automatically, and stop the small sleep pump.
 Regular rotation control, which can prevent the pump seizing by corrosion
effectively, and prevent one pump running all the time. It is suggested that the
power of rotation pumps should be fairish, otherwise it will cause the system
pressure fluctuating.
 Sewage pump control functions, which is used to detect water level of cesspool
and control water level of cesspool.
 Inlet basin water-level detection and control functions, which can detect liquid level
of inlet basin, and adjust pressure-given automaticly.
 Ultra- voltage, under-voltage alarm function of pipe network, inverter supports
ultra- voltage, under-voltage alarm output functions, which can outputs through
programmable relay.
 Set up to motor rated current parameters of no less than seven pumps, and
achieve over-current, overload and other protection for the current pump-run.
 Record failure pump: Record failure pump automatically, and if cleared this record,
please use function of fault clearance.
 Provides standard RS485 Physics communication mode, using master-slave
communication though international standard Modbus communication protocol,
electrical parameters in full compliance with international standards, which can be
achieved barrier-free communication between CHV160A inverter special for water
supply system and the host computer.
