The FWI-SS3 Soft Starter has three types of connection, as following Main
circuit connection: it contains the wiring of 3-phase source input, the output
to motor, and the by-pass contactor connection. External terminal connection
that is the wire comes from twelve external terminals which including control
signal and analogue output signal. Communication connection, there are
two communication interfaces; those are RJ-45 standard web line socket
and Db6socket which are connected to computer.

output
● Terminal ① ② are by-pass output, are used to control the by-pass
contactor. They are normal open contacts and are closed when finishing
starting. The contact capacity is Ac250V/5A
● Terminal ③ ④ are programmable relay output: it is set by FJ code .
They are normal open no-power contacts Please see the detailed inform-
ation in 5.3 item. The contact capacity is AC250V/5A
● Terminal ⑤ ⑥ are fault output , they will be closed when there are any
fault matters happened to the soft starter or power off, while at
normal case they are open. The contact Capacity is AC25V/0.3A
● Terminal ⑦ are Instantaneous stop input, this terminal must be connected
with terminal ⑩ when the starter works normally. But if these two terminals
are both open, the soft starter will stop, and at this time the starter is at the
state of fault protection. Terminal⑦can be controlled by the output contact
of external protection dives, and it is useless when the F12Key is set as 0
(basic protection).
● Terminal ⑧ ⑨ ⑩ are start-up or stop input .There two ways of connec-
tions for your choice, those are 3-wire connection and 2-wire connection.
●Please see the diagram 4.3
Terminal ⑾ ⑿ are DC 0-20mA analogue output ,they show the current
value of motor when real-time working, 20mA is full-scale value and is four
times than rated current of nominal power of soft starter, while, we can
contact a 0-20mADC current meter to check. The Max value of output load
resistance is 300Ω
Note: Please make sure that external terminals are in right connection;
otherwise, the product may be damaged.

in the process of start or stop, and it will show the set and help menu at
other states.
5.1 The Operation of Control Panel
● Open state: you should not press the "run" key until the ready-lamp
lights and show “READY"
● Time-delay state: When the ready-lamp or fault-lamp is shining, it
means it is interval time delay; and when the Display screen shows
"dEXXX", means staring time-delay.
● The "Run" or "Stop" key: In the process of staring, the panel shows
"XXXX" that is the value of start-up current .At this time only "Stop" key
is in use. And the lamps of ready, run and fault are all dark, and you can
not come into the "set" and "help menu" state. While, in the process of
stopping, the panel shows "XXXX" that is the value of start-up current.
At this time, only "Run" key is in use, and the lamps of ready, run and fault
are all dark, and you can not come into the "set" and "help menu” state.
● The "Set" key: Press "Set" key to come into the Set Menu and now the
panel is showing FX: XXX. Please press "Set" key again and Colon is
shining, then you can change the Parameters under the Colon you need
If you want to keep the Parameters changed, Please press "Yes" key, and
if you do nor want, please pressing the "Set" key until the Colon stops
shining, then the Parameters are former .Having finished the above
operation, please press the "Yes" key to return or "Stop" key to return
directly
● The "Yes" key: Press the "Yes" key directly; you will come into Help
Menu and the panel shows HX: XXX. When you finish reading the Help

6. Protection Functions and Explanations
We make our soft starters have all kinds of protection functions to protect
the soft starter and the motor using. Please choose the correct protection
class and parameters according to your application conditions!
Over-heat protection: when the temperature inside soft starter is up to
80℃±5℃,the starter will be into over-heat protection, when it down to
55℃,this protection invalid.
○ Input failure-phrase protection: the delayed time＜3s
○ Output failure-phrase protection: the delayed time＜3s
○ Three-phrase unbalanced protection: the delayed time＜3s,when the
different current value among three phrases is more than 50%±10%,the
protection be used.
○ Starting over-current protection: the diagram 6.1 shows the protection
time when the current is 5 times than the rated working current.
○ Working over-load protection: the starter will be in inverse time thermal
protection on
more
Base of the Max working current of motor (Set by F6 Item),
(The diagram 6.1 s how)
○ Power voltage failure protection: the delayed time is separately less
than 0.5s or 3s when the power voltage is less than half of limited value
or less than setted value.
○ Over-voltage protection: the delayed time is separately less than 0.5s
or 3s when the power voltage is more than 130% of limited value or more
than the setted value.
○ Loading short-current protection: when the current is 10 times
than the motor rated current, it will be short circuited, and the short-
current protection will be take effect, the time is less than 0.1s.
○ The time parameters above start from the time receiving the message till
the protection take effect. The parameters are for reference only, all the protection
function can be proved by the applicaiton or the simulated test, If it is not meet
your demand, the special protection is needed to guarantee the safety.

7. Electrical Test and Application
Please do the following checking before the :
○ If the rated power of soft starter is matched with the Motor or not,
○ If the insulation of motor is meet the demand or not,
○ If the main circuit connection of input or output is correct or not,
○ If all the screws of terminals are twisted tightly or not.
7.1 Electrical Test
● When the power on, the soft starter displays the words of
" CSZPU " or “READY ", and the ready-lamp is on, then press
the "Run" key to start.
● Please set the rated current of the motor of PP parameter.
● Before startting the motor, you should check whether the motor
rotation direction is correct or not, If not, please press the “stop” key
immediately, after cut off the input power,reversing the wiring of motor.

● If the soft starter starts n o t g o o d , y ou c an c he ck w he th er t he starting
mode you choose is suitable for your motor.
Please refer to the detailed explanation at 7.2: the starting mode and application
● If the starting torque of the motor is not big enough, you can increase the
starting voltage ( in voltage control mode) or enlarge the limit-current value
( in current control mode) to enlarge the starting torque.
● It is forbidden to open the upper cover after powered on,
otherwise electric shock may be caused.
● If there is any abnormal voice, smoke or smell , please cut off the electricity
immediately to check and find out the reasons.
● After power on or starting, if the fault-lamp is onand screen displays” Err××",
Please check the Form 7.1 to find out the reason according to the error code.

Fault and Solution (Form 7.1)
Note:When the motor starts successfully , the by- -lamp will be l
ighting, that means the by- contactor is running . At this time,
if the contactor is not closed, the motor will stop running, please
check if the connection of the pass contactor is right or not.
7.2The starting mode and application
There are six starting modes for the user to choose according the motor
and load equipments, as the following:

Note：It is normal that the starting time is less than the setted time under
the light load.This mode generally fits for the occasions where the motor
must be started smoothly
This mode is often used in the conditions which require strict limitation to
the current when starting.
7.2.3 Torque control to start (The P9 item is set as "2"or"3",this starting
mode is valid) Diagrams 7.3 and 7.4 show the output changing waveform
of torque control mode. When the static friction force in the state of heavy
load is too stronger to start the motor, this starting mode can be used,
When starting, the motor needs a very high voltage for a limited time
to remove the static friction force of heavy load, then the ramp voltage
mode or limit-current mode can be used to start the motor.
Note：This mode will cause big-current shock to the motor, so if the ramp
voltage or limit-current mode can be used, please do not choose to use the
torque control mode to start.
7.2.4 Ramp Current to start (The P9 item is set as"4", this starting mode
is valid)
7.2.5 Double closed loop (Both Ramp Voltage and Limit-current)to start
(The P9 items set as"5",this starting mode is valid) This starting mode
uses the control mode of Ramp voltage starting and Limit-current starting
Double Closed Loop circuit, it is a composite starting mode. The Output
voltage waveform is changed as Motor and the load equipments.
7.3 The Stopping Mode and application
The soft starter has two Stopping Modes: Soft-stopping mode
and Free-stopping mode.

7.3.1 Soft-stopping Mode (The P2 item is not set as"0",this stopping mode
is valid) When using this mode to stop the motor, the power to
motor will be transferred from the by-pass contactor to the controlled
silicon of soft starter, and the output voltage of starter will be reduced
gradually so that the running speed of motor can be cut down smoothly
in case of the mechanical shock. The output ending voltage is the same
as the initial voltage. Soft-stopping mode can reduce or remove the surge
of the loading equipments such as the water pump. You can set the soft-
stopping limit-current value through the PF item to reduce the big-current
shock to the motor when stopping. This limit-current value is a percentage.
7.3.2 Free-stopping Mode (The P2 item is set as"0",this stopping mode
is valid) When using this mode to stop the motor, the Soft Starter will
cut off the connection to the by-pass contactor and forbid the controlled
silicon outputting voltage as soon as receiving the order of stopping.
The motor stops gradually because of its Inertia. Generally, if the soft-
stopping mode is not necessary, please choose the free-stopping mode
to length the service life of the soft starter. This mode will completely
forbids the instantaneous output, in case the instantaneous big-current
shock to the motor in special application state.
