4. Connection and External terminal
The FWI-SS 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 pass -by 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.
4.1 The diagram connection (see the diagram 4.1)

www.vtdrive.com
9
4.2 The external terminal
Please see the diagram 4.2
●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 information 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 loose electricity, while at normal case
they are open. The contact Capacity is AC25V/0.3A
●Terminal ⑦are Instantaneous stop input, this terminal must be connected
with terminal ⑩when 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 connections
for your choose, those are 3-wire connection and 2-wire connection.
●Please see the diagram 4.3

www.vtdrive.com
10
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.
4.3 The diagram of Main circuit connection
Please see the diagram 4.4

www.vtdrive.com

4.4 The communication interfaces
RJ-45 is the standard web line socket
DB9 socket has Rs485 and RS232 interfaces inside
Please see the diagram 4.5
The user can choose the following software
1. Computer collector distribution control communication software
2. Device Net interface card and communication software
3. Device Net/Mod-bus/ Profi-bus gateways
4. Others
5. Control Panel and its operation
There are five working states of soft starter, those are: Ready, Run, Fault, Start
and Stop. The control panel will show the current vault of motor when 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

www.vtdrive.com
12
●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 Menu, you can press
this key again or "Stop" key to return. This key not only can be used to keep the
Parameters when you set the parameters you need, but also be sued as
"Returning".

www.vtdrive.com
13
●The "Up" and "Down" ("▲"" ▲") key :In the Set Menu ,you can press these
two keys to choose the Function Code you need when the Colon is not shining
and can choose the Parameters under the Colon when Colon is shining ,It is the
same as the operation in Help Menu. When the Pass-by -lamp is lighting and the
Display Screen shows AXXX which means the operation current value of motor,
now you can press "Up" or "Down" key and the Screen will PXXXX or HXXXX i n t
u n (P X XXX means the apparent power of motor; HXXXX means the over-load
heat balance coefficient, if this value is more than 100%, the Screen shows
"Err06", that means it is at that state of over-load protection.)
Note: 1. only the operation is correct, it will be with the voice when pressing the
key. Otherwise, the operation is wrong.
● the control panel uses the super anti-interference material, so it can be state of
3 meters away.

●F7 the "Max working current”, is basic on the nominal current of motor.
●If you have no any operation for 2 Minutes after you come into the "set" state,
you will return from "set" state.
●You can not set any parameters in the process of starting or stopping.
●If you press the "Yes" key to open the soft starter, you can make the set
parameters recovery to Ex-factory values.
5.3 The function of "Programmable relay output"
This function has two kinds of operation way, those are Programmable time
sequence output and output and Programmable state output.
●When the FJ is set as 0-4(or 10-14), the programmable operation way is time
sequence output, As the following form:

www.vtdrive.com
18
If need programmable relay output time-delay, the delay time is set by F4 code.
●When the FJ is set as 5-9(or 15-19), the programmable operation way is time
sequence output, As the following form:
●The way of programmable state output is used to show the working state of soft
state, and under this way, the F4 code is un-useful; The ex-factory value of FJ
code is "7"showing the ready state of soft starter and at this time the motor can be
started up; when the programmable output is in fault state, the faults m＞＞mean
the fault of motor, such as fault of Err05, Err06, Err12, Err15,and they are different
form the faults come from the terminals⑤⑥ output.
●When FJ＞9,the reset state of programmable output is normal closed ,that is”
inverse phase output"
5.4 The function of Re-start
When the FE item is not set as "0", the Automatic Re-start function is in use. This
function is affective only the External Control connection is 2-wire way and is not
controlled by the FD item (External Control allowed). When it is 2-wire way you
can:
●Having got electricity and delay time for 60 seconds, the soft starter will Re-start

www.vtdrive.com
19
automatically.
●Having stopped because of any fault and delay time for 60 seconds, the soft
starter will Re-start automatically
●the total number of times of automatic re-start is "n" times,"n" is set by FE item.
●the function of automatic re-start is effect only when getting electricity and
opening again
●The soft starter has the protection function of under-voltage ,so when the
electricity be cut off and then get on again ,the soft starter will not Re-start no
matter which state the control terminals at, in case of the danger to operator. But if
the Automatic Re-start is allowed, the Protection function of under-voltage is no
use.
5.5 Directions for other set items
You can use F8 item choose the Input way and Display Way.
