B601D

The B601D series is a single-phase intelligent constant pressure inverter pump controller for fully automatic control of water pumps, with high quality, multi-functional, low noise and high usability, etc.
The peripheral detection and control components used have no special requirements and can be used for general purpose components. For example: pressure detection can use the output signal for 4 ~ 20mA, 0 ~ 5VDC, 0 ~ 10 VDC standard signal sensors, transmitters (including water level transmitters, temperature transmitters, etc.) or inductive remote pressure gauge, etc., can also use resistance remote pressure gauge.
For simple control an electric contact pressure gauge or pressure relay (pressure switch) can be used; for water level control switches float switches, water level relays and other general purpose devices can be used. These measures enable users to match appropriate peripheral devices according to local conditions.

Product description

B601 series products are constant pressure water supply controllers specially designed for single-phase motors.


Features

B601 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.

Cautions

Dangers

1. Do not disassemble or modify, otherwise it may cause electric shock, fire, or injury.

2. Do not open the cover during power-on.

3. Do not put wires, thin rods, filaments, and other items into or fall into the controller to avoid short circuit or electric shock hazard.

4. Do not splash water or other liquids.


Warnings

1. Do not perform voltage withstand test on the internal components of the controller;

2. Never connect the power cord to the output terminals U, V, W;

3. If the circuit board components inside the controller are affected or damaged by static electricity, please do not touch them casually;

4. The motor and controller should match the power supply specifications, otherwise it may cause abnormal operation or even burn out the equipment;

5. If there is severe vibration, noise, heat or odor during the initial operation, turn off the power immediately and contact the supplier or service center;

7. Do not expose the product directly to outdoor environments such as sunlight, frost, snow, etc., to avoid deformation or electric shock damage.


Troubleshooting


Fault code

Explain

Possible reason


Solution


LP


Low water pressure


Insufficient water; motor reverses

Check whether the pressure sensor is normal and whether the rotation of the motor is correct

Yes, whether parameter b01.01 is set too large, and whether the water supply pipe network system is abnormal


HP


High water pressure


Parameter setting is low

Check whether the pressure sensor is normal, whether the parameter b01.00 is set too small, and whether the water supply pipe network system is abnormal


LL


Low water level

The water level of the pool is too low; the municipal pipe network has insufficient water supply


Check the water inlet system, the connection between the water level switch and terminal S1


E022


Transducer failed

Sensor open circuit; sensor short circuit;

PID feedback source disappeared


Check whether the connection line between the sensor and the controller, the feedback source, and the pressure sensor are 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.

G. Tear off the product identification (such as nameplate, etc.) without authorization; the serial number of the body does not match the warranty card.

3. If you have any questions, please contact the agent or contact our company directly.

4. For machines beyond the warranty period, our company will also provide lifetime paid maintenance services.
