2 Introduction
2.1 Safety guidelines
Read this manual carefully before operating the equipment and follow its’ instructions.
Installation, operation and maintenance should be in strict accordance with this manual,
national codes and good practice. Installation or operating not performed in strict
accordance with these instructions will void manufacturer’s warranty.
Disconnect all power inputs before servicing the soft-starter and/or the motor.
Prior to the installation, check and verify that no parts (bolts, washers, etc) will fall into the
starter.
When this
symbol is shown in the manual, extra care must be taken concerning mains
live voltages.
Do not use insulation resistance- measuring instruments with insulation test voltages higher
than 500V when the soft starter is connected with the motor.
Attention
This product was designed and tested for compliance with IEC 60947-4-2.
The soft starter SST330i and SST360i are VDE certified.
Use of the product in domestic environments may cause radio interference, in which case
the user may be required to employ additional mitigation methods.
Utilization category is AC-53a or AC-53b. Form 1.
For further information see Technical Specification.
Warning
A series contactor or switch will be required when in case of a starter switch-off
malfunction it is necessary to switch off the load by a second switching device. This in
order to prevent danger or damage.
Internal components and P.C.B’s are at Mains potential when the soft starter is connected to
mains. This voltage is extremely dangerous and may cause death or severe injury if
contacted.
The SST330i and SST360i soft starters are an open board. The user has to care for a
corresponding cabinet and a safe installation to avoid accidental contact with the parts
which are conducting. Assembling in a closed cubicle or usage of a plastic coverage is
recommended.
When the soft starter is connected to Mains, even if start signal has not been issued, full
voltage may appear on motor’s terminals. This is also valid if the motor has been stopped or
if no control voltage is connected.
Starter must be properly grounded (except 8-22A) to ensure correct operation and safety.
Check that Power Factor capacitors are not connected to the output side of the soft starter.
Don’t interchange the mains- and the motor- connections.
Safety Guidelines require a proper circuit breaker and/ or short circuit protection in front of
the soft starter.
Grounding (PE) of the PCB is necessary. Therefore use the PE clamp on the left side
under the PCB.
2.2 ESD Precautions and Handling:
The starter itself is not particular sensitive for Electro-Static Discharge (ESD), however precautions are still
important and necessary.
The starter is produced in an ESD-safe environment.
The carton packaging box is made out of natural paper fibres without any charge collecting plastic particles or
plastic top sheet.

Before the starter is taken out of the carton, one needs to discharge his body by touching or holding a
conducting, not painted, metal part of the machine or installation were the starter must be build-in. A
grounded metal part is very much preferred.
Open now the starter's carton and take out the device by its aluminium heatsink block.
Do not touch the sensitive vertical control board. The horizontal power board may be touched.
Mount the starter into the machine or installation and hook up the wires.

Thermal Electro-Dynamic Overload Relay for the 1- and 3-phase Mains.
4 General description
4.1 "SimpleStarter" general purpose digital Softstarter
The "SimpleStarter" softstarter is designed as a device for simple and low cost soft starting of 3-phase 400V~
induction motors, with a low or moderate starting torque:
Heat pumps & Chillers
Pumps
Fans
Conveyors (light, moderate)
Refrigerant Compressors
Mixers
Production machines
Transformers (3-ph)
Beverage installations
The "SimpleStarter" controls the motor voltage in all the three phases from. The device is equipped with three
build-in bypass relays. The "SimpleStarter" is developed with the aim to replace the star/delta (Y/D) switches in
applications where a galvanic separation is of lesser importance or already realised.
All "SimpleStarter" softstarters comply with all directives concerning emission, immunity and safety. The unit
is of an open frame type (IP00), therefore the user has to take care for a proper housing in. When the mains
voltage is applied or when the starter receives a starting signal, the power semi-conductors are switched-on in
such a way that it starts with a small controllable increasing current, flowing into the motor. When the motor is
at speed, the bypass relays are switched on the power semiconductors are switched off thus minimising
EMC/RFI pollution.
For the operation of the softstarter, a neutral line is not necessary.

Fig. 3.1 Principal schematics of "SimpleStarter".
The "SimpleStarter" electronics is powered by the line voltage and is partly not isolated.
Both PCB boards of the device have parts that are at live voltage, so do not touch!
(see the Safety Guidelines). The control circuit is isolated from the mains and should be connected to PE to
ensure safe operation:

5 Control section description
5.1 USB Diagnostics program (examples taken from the SST360i device)
Manipulating of the Starters parameters is done with the 'Diagnostics program'. This program
‘SimpleStarterDiag.exe’ comes together with ‘SSTsettings.ima’ and ‘mcHID.dll’. The three of them should
always be kept together in a single random chosen Windows map.
Run the Diagnostics program ‘SimpleStarterDiag.exe’ and connect the PC with a proper USB cable (Type A to
Mini B) to the SimpleStarter. Then apply the 3-phase mains voltage to the SimpleStarter.
Once the connection has been established the upper status bar shows some general information like Connection
status, Company Name (OEM situations), Starter Type, Software Version and the motor status which can be:
Motor Stopped; Motor Starting; Motor at speed; Motor Stopping.
To switch the control to the Diagnostics program click on the 'Starter' button. It will now show 'PC', all the
controls on the screen become active. The settings that are made on the screen will be taken over by the Starter.

However, keep in mind that once the control has been given back to the Starter these new settings are lost and
the previous ones will be used unless they where saved first by clicking the 'Save Parameters' button.
5.2 Starting
A general rule says the shorter the acceleration time the higher the starting current, the less the backup fuses are
heated and the higher the mechanical stress will be. A longer starting time minimises the mechanical stress but
will increase the energy loss in motor and starter.
There are three ways of starting the motor:
5.2.1 Auto Start
Use this way when the mains voltage is applied by switching an upstream contactor (external Start/Stop mode
set to Start On Open see 5.2.2 ). For the SST360i type allways use a controlled line separator/contactor to
switch-off in case the SST360i fails to switch-off.
5.2.2 The external 'Start-Stop' switch
The external 'Start-Stop' switch can configured from firmware version 1.04 with diagnostics screen version 1.3.
The Starter will ramp down
when the switch is opened
(Stop On Open).
The Starter will ramp up when
the switch is opened (Start On
Open).
