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.

4.4.2 Circuit Breaker
It is necessary to connect a suitable circuit breaker between 3 phase AC power
supply and W713B series intelligent constant water supply controller. The capacity of
breaker is 1.5~2 times to the rated current of controller.

4.4.3 AC Reactor (Optional)
In order to prevent the rectifier damage resulted from the large current, AC
reactor should be installed at the input side. It can also prevent rectifier from sudden
variation of power voltage or harmonic generated by phase-control load.
4.4.4 Input EMC Filter (Optional)
EMC filter can minimize the interference of the surrounding device which may
be disturbed by the cables when the controller is working.
4.4.5 Output EMC Filter (Optional)
EMC filter should be installed to minimize the leak current caused by the cable
and minimize the radio noise caused by the cables between the controller and motor.
4.4.6 Output Reactor
When the distance between the W713B controller and motor is more than 50m,
the controller may be tripped by over-current protection frequently because of the
large leak current resulted from the parasitic capacitance with ground. So as to avoid
the damage of motor insulation, the output reactor should be installed.
4.4.7 Ground Wiring
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.

▲At the primary interface, press will enter the first-level menu then press
will return to the primary interface;
▲At the first-level menu, press will enter the second-level menu. In
second-level menu can also press and return to first-level menu or
enter third-level menu;
▲At third-level menu, press or can return to the second-level menu,
difference is: pressing will save the parameters into the controller and
return to the second-level menu with shifting to the next function code
automatically; while pressing will directly return to the second-level
menu without saving the parameters, and keep staying at the current function
code.

rated max. range of transducer is 16.0bar,
b01.05 should be set to 16.0;
Set the control range of “Constant
Temperature” or “Constant Differential
Temperature” in parameters b01.07 and
b01.09 (water outlet), b01.12 and b01.14
(water inlet).

Corresponding Setting of Lower Limit
(b01.07, b01.12) use to transducer
minimum setting
Higher limit (b01.08, b01.13) use to
accordant display and transducer: when
display smaller than the actual, decrease
higher limit; when display greater than the
actual, increase higher limit
Corresponding Setting of Higher Limit
(b01.09, b01.14) use to transducer
maximum setting
When analog input is interfered, prolong
filtering time so as to increase the ability of
anti-interference, but decrease the
sensitivity.
