Product description
B713 series products are not only the integrated intelligent controller designed for water pump, but also the intelligent controller designed for the central air-conditioning water circulation system to realize the differential constant pressure control.
Features
l Suitable for various constant pressure/constant differential pressure water supply applications.
l After parameters were set correctly, the system can operate automatically with constant pressure or constant pressure difference according to the water consumption without manual operation;
l Stop running automatically when no water consumption;
l Alarm automatically when faults occurred;
l Alternate running automatically in the multiple pump system, prolong the using life of pumps.
Product advantages
◆ Multi-Pumps Control Function: Max.6 pump linkage water supply
◆ Sleep Function: Sleep down when have no water consumption, to earn a better energy saving
◆ Freeze-Proofing Function: Suitable to low temperature area, prevent pump from freezing
◆ Anti-clogging Function: Take precaution against pipe clogging and clean the pipe dirt
◆ Power On Restart: Running automatically when power on
◆ Master Fault Shift Automatically: Keep on working when the master break down
◆ Alternate Running: Balance every pump’s running time, prolong service life of the whole unit machine
◆ Control Mode: Constant pressure, constant differential pressure, manual
◆ Linkage Mode: Synchronize, master-slave, big-small pump combination, one duty one standby
◆ Terminal Control Mode: Electronic contact gauge control, manual/auto control, terminal run/stop, automatic water level control
◆ Various of Water Supply Fault Alarm Function: High-pressure, low-pressure, low-level, transducer error etc.
◆ Many Fault Protection Function: Over-current, over-voltage, low-voltage, phase-failure, over-Load etc.
Product parameters
◆ Input Voltage Range: 380V±15%
◆ Input Frequency Range: 47~63Hz
◆ Output Voltage Range: 0~rated input voltage
◆ Output Frequency Range: 0~50/60Hz
◆ Digital Switch Input: 4 input
◆ Analog Signal Input: AI1: 0~10V or 0/4~20mA input; AI2: 0~10V or 0/4~20mA input

Cautions
WARNING: Wrong using may result in death or serious personal injury.
l Please don’t dismantle, change the product, or may cause electric shock, fire hazard and personal injury;
l Please don’t open the cover during the running of controller;
l Please don’t put wire, bar of metal, filaments etc. into the controller so as not to cause a short circuit or get an electric shock;
l Please don’t splash water or other liquid over the controller.
CAUTION: Wrong using may result in the damage of controller or system.
Please don’t make withstand voltage testing for the controller;
Never connect AC power to output UVW terminals;
If the internal components of the controller were influenced or damaged by static, please do not to touch;
The motor, controller and power specifications should be matching, otherwise it could cause abnormal operation even burn out the device;
If the controller appears serious vibration, noise, heat or peculiar smell in the first operation, please cut off the power immediately and contact suppliers or service center later;
Please don’t install the controller in the environment with direct sunlight, rain, frost or snow in case of deformation or damage.

l Abnormal sensor; l Motor rotates in the reverse direction; l Insufficient water inflow; l There is air inside the pump | l Check the installation of pressure transmitter; l Check the motor’s direction of rotation is correct or not; l Check the parameter b01.01 (setting value too big); l Check the pump whether is vent out the air inside |
LP2 | Low Water Pressure at Inlet |
l Abnormal sensor; l Insufficient water inflow; | l Check the installation of pressure transmitter; l Check the parameter b07.00 (setting value too big); |
HP | High Water Pressure | 1. Abnormal sensor; 2. The parameter b01.00 setting value is too small | l Check the installation of pressure transmitter； l Check the parameter b01.00 (setting value too small) |
LL | Low Water Level | 1. Water level of pool is too low; 2. Abnormal water level switch; 3. Wrong setting of water level switch style parameter | l Check the water system l Check the situation of the control terminal S3 l Check the parameter b05.00 |
E022 | AI1 Sensor Fault | 1. Pressure transmitter disconnected; 2. Wrong pressure transmitter wiring; 3. Pressure transmitter short circuit; 4. Pressure transmitter break down | l Check the cable between pressure l Transmitter and controller; l Check the sensor whether is normal |
E033 | AI2 Sensor Fault | 1. Pressure transmitter disconnected; 2. Wrong pressure transmitter wiring; 3. Pressure transmitter short circuit; 4. Pressure transmitter break down | l Check the cable between pressure l Transmitter and controller; l Check the sensor whether is normal |
After-sales service
1. The warranty is limited to the inverter itself. Within 12 months from the date of purchase, the inverter will provide free maintenance services if the product is damaged due to malfunctions caused by the product itself within 12 months from the date of purchase.
2. During the warranty period, if something happens, our company will charge a certain amount of maintenance fee depending on the situation.
A. Failure to strictly follow the "Instruction Manual" or exceed the standard requirements in an environment that does not meet the requirements of the "Instruction Manual".
B. Failure caused by self-repair or modification without permission.
C. Faults caused when the inverter is used for abnormal functions.
D. The inverter is damaged due to incorrect wiring.
E. Damage caused by improper storage, fall or other external factors after purchase.
F. Failures caused by natural disasters such as abnormal voltage, lightning, fire, water mist, metal dust, gas corrosion, earthquakes, storms, or disaster-related causes.
