one pump and one variable frequency controller, which can effectively extend the

motor service life; the controller system supports max.6 pumps linkage work, meet

the customers’ operating requirements.

With high quality, multi-functional, low noise and strong commonality etc.

characteristics, W713B multi-function energy-saving controller is suitable to

full-automatic operation.

Suitable for various constant pressure/constant differential pressure/constant

temperature/constant differential temperature water supply applications.

After parameters were set correctly, the system can operate automatically with

constant pressure/constant differential pressure/constant temperature/constant

differential temperature according to the water consumption without manual

operation;

Alternate running automatically in the multiple pump system, prolong the

using life of pumps.

Restart automatically when power recovery

Stop running automatically when no water consumption;

1. SAFETY PRECAUTIONS

W713B is a new power electronic product, please read the operation manual

carefully before using to keep your safety and make sure proper operation.

In this manual, the safety precautions were sorted to “WARNING” and

“CAUTION”.

WARNING: Wrong using may result in death or serious personal injury.

CAUTION: Wrong using may result in the damage of controller or system.

WARNING

Please don’t dismantle, change the product, or may cause electric shock, fire hazard and

personal injury;

Please don’t open the cover during the running of controller;

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;

Please don’t splash water or other liquid over the controller.

CAUTION

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.

Warm reminder:

For convenience, the controller has set default with a nonzero AI1 feedback lost

detecting value, if here hasn’t pressure signal feedback into the terminal AI1, the

controller will be starting up failure and displaying “E022”, just take follows:

◊ If the controller worked as a master, please connect a transducer to the

controller and then press the key;

◊ If it worked as an auxiliary, it should be setting as AI1 feedback lost detecting

value (b02.08) 0 and then pressing the key to reset error warning.

3. ENVIRONMENTAL REQUIREMENT

1. Environment temperature range: -10℃～40℃, controller will be derated at 4% on

every 1℃if ambient temperature exceeds 40℃, the maximum temperature is less

than 50℃.

2. Prevent rain drops, moist environment, oil fog, salt erosion, corrosive gas, etc..

3. Prevent direct sunlight, keep away from radiation source.

4. Prevent violent vibration or sudden impact.

5. Lower than 1000m installation altitude, if exceeds 1000m, inverter will be derated

at 1% on every 100m.

CAUTION

When moving the controller please lift by its base and don’t lift by the panel. Otherwise may

cause the main unit fall off which may result in personal injury.

Install the controller on the fireproofing material (such as metal) to prevent fire.

When power off, should not install the controller until the power indicator light was

extinguished, which can ensure the device has been discharged completely.

Disconnect all power line before opening front cover of unit. Wait at least 5 minute until DC

Bus capacitors discharge.

Terminals of ground

In order to keep safety and prevent electric shock and fire, “PE” must be

grounded with ground resistance. Furthermore, reliable grounding is the simplest,

most effective and minimum cost solution for EMC problems, so it enjoys priority in

all EMC methods.
