740Series
Smart Water Pump Drive
User Manual
740drive allows your pump to work more efficiently,safely and smartly, reduce a large amount of
energy consumption and prolong the lifetime of your pumps.
740drive is made of high quality components and materials and adopts the latest microprocessor
technology.
This manual is issued for consumers to easily and properly operate the smart 740drive.The
information contained in this manual is subjected to change without prior notice.
Safety Precautions
In order to ensure the proper and safe use of 740drive series and avoid any possible damages on the
operator,drive or pump,please affirm to read carefully the below tips before installation and operation.
1 / 21
· Do not operate the equipment with power on, cut off the power and wait for at least 10 minutes before
wiring and inspection,or it would probably cause electric shock.
· The main circuit terminal must be connected to the power cable tightly or it would probably cause
damage on pump due to loose connection.
· Do not leave any other objects inside the drive,such as wire fragments,soldering tin,metal,etc. It would
cause electric short circuit to burn out the drive.
· Do not install capacity or piezoresistor on the output end of drive,or it will cause breakdown or fault on
the drive or even damage some critical components. Please remove it if there is any exsisting capacity
or piezoresistor

Basic Functions
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 in
real 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
4 / 21
stops running automatically to avoid
damage on pipe network due to high
pressure. Automatic Energy-saving Running

1.Indicator Lights
PRESS. Pressure setting is valid only when the light is on
RUN
Constant lighting means pump is running,while flickering means pump is in sleep
status
STOP Constant lighting means pump is in stop status. Online Flickering means inverter is in the multi-pump control mode
Manual Light-on indicates pump runs at a given frequency set by hand
Auto Light-on indicats pump is running in constant pressure mode
Low flow Light-on means pump is under protection against water shortage
Sleep Light-on means pump is sleeping .
2. Function button
Used to switch inverter from fixed mode to parameter setting mode
Used to set parameters and modify pressure values
