In the power stage, the line voltage is controlled by means of
6 SCR’s that allow the variation of the conduction angle of
the voltage supplied to the motor.
For the internal supply of the electronics, a linear source is
used with several voltages, fed independently of the power
supply.
The control board contains the circuits responsible for the
control, monitoring and protection of the power components.
This board also contains the control and signalling circuit to
be used by the user according to its application as a relay
output.
All parameters or controls for the operation of the Soft-Starter
can be displayed or changed through the HMI.

or the line supply isolation contactor must be able to carry
the motor rated current, and the motor connection cables to
the Soft-Starter, and/or the bypass contactor must be able to
carry 58% of the motor rated current.
2) Due to the high currents and cable cross sections, it is also
suggested to use copper bus bar for this type of connection.
3)When 2 poles motors are in full voltage it is necessary a
minimum of 25% ofload applied to its axle. When thiscondition
can not be taken, a bypass contactor is necessary.

When installing the signal and control wiring, please note
the following:
Cable cross-section: 0.5...1.5mm2;
Relays, contactors, solenoid valves or breaking coils
installed near to Soft-Starters can generate interferences in
the control circuit. To eliminate this, you must install RC
supressors connected in parallel with the coils of these device,
when fed by alternate current and free wheel diodes when
fed by direct current.
When an extern HMI is used, the connection cable to the
Soft-Starter should be passed through the slot at the bottom
of the Soft-Starter.This cable must be laid separate from the
other cables existing in the installation, maintaining a
distance of 100mm (3.94in) each other.

The HMI-3P is a simple interface wich permits the operation
and the programming of the Soft-Starter.
It permits the following functions:
Display of the Soft-Starter operation status, as well as
the main variables
Error display
Display and changing of the adjustable parameters
Soft-Starter operation through the keys START ("I") and
STOP ("O")
All functions relating to the Soft-Starter operation (enabling
(ON - "I") disabling (OFF "O"); increment/decrement (values/
parameters) can be performed through the HMI-3P. This is
made through standard factory programming of the SoftStarter. These functions ON, OFF and Reset can also be
executed individually by means of digital inputs. So it is
necessary to program the parameters relating to these
correspondent functions and inputs.

The standard factory parameters are predefined values, with
which the Soft-Starter is programmed at factory. The set of
values is so selected to meet most applications, thus reducing
the reprogramming during the start-up. If necessary, the user
can change each parameter individually according to this
application. At any time the user can return to the standard
parameter set at factory, adopting the following procedures:
They define the Soft-Starter
characteristics, the functions
to be executed, as well as
the input/output functions.

End setting of the pump control function:
NOTE!
This setting must be used only to improve the performance
of the pump control and when the pump is already installed
and able to operate at full-load.
1. Set P45 (Pump control) at "On".
2. Set P14 (undercurrent) or set P15 (Undercurrent Time) at
"OFF" until the set has finished. After then, program it again.
3. Check the correct direction of rotation of the motor, as
indicated ON the pump frame.
4. Set P01 (initial voltage - % UN) to the level so the motor
starts to run without vibration.
5. Set P02 (Acceleration Time [s]) to the starting time required
by the load. With the manometer in the pipeline, check the
pressure increase that must be continuous until the max.
required level is reached without overshoots.
If overshoots occur, increase the acceleration time to reduce
this pressure overshoots at maximum.

DETAILED PARAMETER DESCRIPTION
For thedelta inside connectiontheSoft-Starter SSW-03isinstalled
separately in each winding of the motor through 6 cables. In
this type of connection the circulating current of the Soft-Starter
is only the 58% from the nominal current of themotor. This characteristic changes the relation between the motor nominal current and the nominal current of the Soft-Starter. To know, in this
connection, the Soft-Starter can be specified as:
- 1.50 times the nominal current of the motor, during the start;
- 1.73 times the nominal current of the motor, in full voltage.
During the start the relation is lesser because had the common
characteristics to this type of connection (inside of the Delta) the
Thyristorofthe Soft-Starter needstoleadthe samecurrentinalesser

The standard connection requires lessoutput wiring. The connection within the motor delta connection requires twice the

ATTENTION!
To perform the connection within the motor delta connection,
your motor must have the correct delta connection voltage.
NOTE!
1)When the connection within the motor delta connection is
used, as shown in Item 9.9, the connection cables of the SoftStarter to the line supply, or the line supply isolation contactor
must be able to carry the motor rated current, and the motor
connection cables to the Soft-Starter, and/or the bypass contactor must be able to carry 58% of the motor rated current.
2) Due to the high currents and cable cross sections, it is also
suggested to use copper bus bar for this type of connection to
connect the Soft-Starter to the line supply.
3) For 2 pole motors must have a minimum 25% load applied
to the axle when in full voltage. A ByPass contactor is necessary when that condition are not possible.

Protection
The Soft-Starter SSW-03 Plus is fitted with a Thermal
Protection. This protection is very efficient for the motor
protection. All Soft-Starter SSW-03 Plus models are fitted
with this protection and always it is activated, error E04
is displayed and the motor is switched off.
This thermal protection has curves that simulate the motor heating and cooling. The calculation is performed
through a sophisticated software that estimates the motor temperature by means of the current that is supplied
to the motor.
The actuation curves of the motor Thermal Protection
are according to IEC 60947-4-2 standard.
The motor heating and cooling curves are based on long
experience of the company with its motors. These curves
adopt a standard three-phase motor with IP55 degree of
protection. These curves also consider if the motor is
cooled during operation or not.

DETAILED PARAMETER DESCRIPTION
The cooling time of the thermal image depends on the
motor power, i. e., for each power, a different cooling
time is considered. If a different cooling time is required,
this setting can be made at P27.
The estimated value for the motor temperature is saved
in non-volatile memory always the control board is
switched off. Thus, always the control board is switched
on, the last saved value will be returned.

DETAILED PARAMETER DESCRIPTION
EXAMPLE:
Correction of the actuation time:
A motor operating at 80% In is switched off and switched
on immediately.
The starting duty is 3xIn @ 25s. The selected Thermal
Class is Class 20 with 39s @ 3xIn.
The correction factor for 80% In in the table 6.4 is 0.35.
The corrected actuation time is: 0.35 x 39s = 13.7s, the
actuation time is reduced from 39s at cold condition to
13.7s. This means that a immediate start is not possible
before the thermal image of the motor has been cooled
down.
NOTE!
For programming correctly the Thermal Class that should
protect the motor against overheating, you must consider
the allowed hot locked rotor time. This data is available in
the catalog of the motor manufacturer.
EXAMPLE:
Suggestions on how to program the Thermal Class
correctly:
Motor data:
Power: 100hp
Voltage: 380V
Rated current (In): 140A
Service factor (S. F.): 1.00
Ip/In: 6.6
Lockedrotor time: 12s at hot (Standard catalog information)
Speed: 1780rpm
Data about the motor + load Starting:
Starting by Voltage Ramp, average starting current:
3 x the rated motor current during 25s (3 x In @ 25s).
1) In the cold chart Figure 6.10, we can find the
minimum required Thermal Class that allows motor start
with reduced voltage:
For 3 x In @ 25s, we select the next higher class: 15
88
2) In the hot chart Figure 6.11, we can find the maximum
Thermal Class that the motor will withstand due to the
hot locked rotor time:
For 6.6 x In @ 12s, we select the next lower Class: 30
6
DETAILED PARAMETER DESCRIPTION
Now it is known that Thermal Class 15 allows cold start and
Thermal Class 30 is the upper limit. Thus you must select a
Thermal Class between these two Thermal Classes by
considering the number of starts per hour and the time
interval between motor On-Off procedures.
With a smaller Class selected, the motor protection will
increase but, less starts per hour are allowed and longer
time intervals between motor On-Off procedures are
required.
On the other hand with a higher Class selected, the motor
might be operated closer to the limit, thus more starts per
hour are allowed and shorter time intervals between motor
On-Off procedures can be used.
If you are not sure which Thermal Class should be adopted
between these two limits, adopt the lowest Thermal Class
firstly, and only during practical tests at full load operation
select the Class that is more suitable to your requirements,
without exceeding the upper limit.

NOTE!
If several Thermal Classes can be applied, program one that
is most suitable for your application, protecting your motor
according to your duty requirements.
NOTE!
If the motor is equipped with a temperature sensor (PTC or
Thermostat) which is used for thermal protection, the
thermal class of the SSW-03 Plus can be disabled by setting
P21= Off.

ion gun (ex: charger buster ion gun (non-nuclear) Ref.
A6030-6 from DESCO). If necessary remove PCBs from
the Soft-Starter.
1. Disconnect power supply of the Soft-Starter.
DANGER!
Disconnect always the supply voltage before attempting to
service any electric component of the Soft-Starter.
Even after switching OFF the Soft-Starter, during a certain
time high voltages may be present. Thus wait 3 minutes to
allow a complete discharge of the power capacitors.
2. Open the enclosure of the Soft-Starter.
3. Find the fuse on the board CCS3 and replace it by the type
specified in the spare parts list.
