Ausenist Single Phase 220V Two Wires Output Inverter Frequency Converter VFD for Water Pump
The host detects the pressure of the pipe network and sends it to the auxiliary machine, while automatically controlling the auxiliary machine operation stop and PID status according to the pressure condition.

The host machine detects the status of the auxiliary machine in real time and when the host machine fails, the standby host machine automatically becomes the host machine and when the auxiliary machine fails, it automatically skips the auxiliary machine and starts the next auxiliary machine. Ensure that the pump set can achieve automatic switching of the main and auxiliary.

The main and auxiliary engines can be run alternately at regular intervals and in sequence to achieve even use of the pumps and extend their life.

	Replay Output	1 way output,pragrammable
Basic Functions	Open Collection Output	1 way output,pragammable
	Command Running Channel	Three kinds of channels: 1.Operational panel 2.Control terminal,3.Serial communication port,choose 1 and 2 for master drive and 3 for auxiliaries
	Built-in PID	Advanced PID arithmetic to realize closed loop control system
	Stall Speed Control	Automatically limit current and voltage at running period to prevent tripping due to frequent overcurrent or overvoltage
	Master and Auxiliaries connection	Extensible RS485 design,one drive in the system can be master and controls the other auxiliary drives (4 at most) to work by communication mode, Master drive sends PID feedback information to the auxiliary drives and monitors status of auxiliaries inreal time.Any failure of the auxiliary drives does not affect the others.
	Water Shortage Protection	If the drive detects the pipe pressure is lower than the water shortage pressure set value,the system stops working automatically.After set period time,it restarts automatically for specified times.If pressure restores to normal,system works normally,otherwise,system stops automatically in case of idle running of pump and prolongs pump lifetime to the maximum extent.
	High Pressure Alarm	When pressure exceeds set pressure,it stops running automatically to avoid damage on pipe network due to high pressure.
	Automatic Energy-saving Running	Automatically lower output voltage under light loading to save energy
	Password Setting	4-bit password can be set with non-zero numbers,Exit password setting interface and the password will be valide in 1 minute.
	Parameters Locking	Define whether the parameter is locked in running or stopped status in case of misoperation.
