There are three pairs of anti-parallel thyristors connected to the stator of
motor. Using the electric switch feature of the thyristors, the voltage of the
motor can be controlled by changing the triggering angel of the thyristors.
The triggering angel of the thyristors is controlled by microprocessor. So
the motor canbe started softerand smooth.After the equipment is up to
full voltage, it outputs a bypass signal. User can use this signal to control
the bypass contactor to supply the motor. See figure4-1.

temperature is toohigh (protection ofoverheating) etc.Any fault is
detected, the systemimmediately enter Faultmode. If no fault is

Ready
When the soft Starter is power on, self-inspection is performed. The
self-inspection includes: testthe parameters thatthe user changed
(fault protection ofparameters setting), checkif the phase of voltage is
not right (protectionof missing supplyphase) and checkif the system
temperature is toohigh (protection ofoverheating) etc.Any fault is
detected, the systemimmediately enter Faultmode. If no fault is
detected, the system enter the Ready state , and rdy shows on the

11.1 Inspection before running11.1 Inspection before running
Is the power of the soft starter matched to that of the motor?
Does the insulationof the motormeet the requirement?
Is the wiringof power andline right?
Do all thenut screw tightly
Does bypass contactor connect correctly?
Measure the inputpower (R\S\T) usingmultimeter, Checkwhether
there is shortcircuit.

11.2 Power on and trial running11.2 Power on and trial running
When power is on, system enter READY state, rdy shows on the
keyboard (If whatshows on thekeyboard is notright, see thechapter
"Fault explanation and solutions")
When power is on, system enter READY state, rdy shows on the
keyboard (If whatshows on thekeyboard is notright, see thechapter
"Fault explanation and solutions")
If what shows on the keyboard is right, jogging can be used to judge
whether three-phase outputcurrent is balance.The operation show as
follows:
Set the startmode to ,and the control mode to .
Press key, check whether the 3-phase current is balance using
current measure meter (at this time, because the voltage is too low,
the motor maynot rotate. Itis normal)
If above testresult is normal,user can operate the soft starter to
start and stop the motor as normal. Press key to start motor,
after the startsequence complete, thebypass contactor came into
work automatically. Shows onthe keyboard. The motor enter
normal running state, Press key to stop the motor.

If there isfault protection, inthe course oftrial running, thenFault
Code will shows on the keyboard, for detail see Fault explain and

After power ison, do notopen the shellto avoid gotten an electric
shock.
At the courseof trial running, any abnormal phenomenon is fond, such
as: Abnormal sound, Smoking or abnormal smell, user should cut off
the power immediately.
If the motor is not connected to the output power connections U V
W of the soft starter, When power is on, 380V can be measured at the
output power connections. This is inductive voltage. This is normal
phenomenon. When the motor is connected to the output power
connections, this inductivevoltage disappears immediately.
During trial running, if the starting effect is not ideal, user can modify
the correspond parameter such as starting mode, current, voltage and
time etc.
