Key Features

PSTB30 300

LCD display

The display of the PSt gives you information presented in plain words
in required language. You can choose between 14 different languages
including English, German, Italian, Chinese, Finish, Swedish, French,
Spanish, Dutch, Portuguese, Russian, Turkish, Polish and Czech. On the
PST display, you get all the information you need to set up, adjust and
trouble-shoot. This makes the PST extremely easy to handle and reduces
the risk of misinterpretations.

Four button keypad

The PST employs the same basic user concept as today's advanced
mobile telephones. Using the four buttons on the keypad, you can easily
adjust your own start and stop profile and motor protection functions
for any type of applications including pumps, conveyors, fans, mixers
and compressors for quick and easy set up.
You can also set the advanced warning parameters to allow
potential problems to be identified before real problems occur. a
password protection function is available to prevent unauthorized
changes to the programming.

Starting several motors

You can store as many as three different starting parameter sets for
optimal sequence start of three different motors. You can use this
fuction for two or three speed motors as well.

Integrated advanced motor protection

Inside the PST Softstarter, you will find useful features for advanced
motor and softstarter protection, including; programmable overload
protection, high current, underload, phase imbalance, phase reversal,
thyristor overload protection, and bypass monitoring to ensure proper
by-pass operation

Programmable signal relays

All PST units have three programmable signal relays where each relay
can signal Run, Top of Ramp or Event. The Event setting can be used to
signal protections, faults and warnings. The supervisory functions
monitor not only software and critical softstarter functionality but
also phase loss and out of frequency range.

Integrated by-pass contactor

On the larger sizes (PSTB 370 ... PSTB1050), there is an ABB AF
contactor integrated. This gives you advantages in terms of
cost-saving, space saving and last but not least energy saving. With a
by-pass contactor you can reduce the power losses during normal run by
90% or more.
The smaller units, PST30 up to PST300, which are not equipped
with a built-in by-pass contactor, have and extra set of three
terminals on the line side. The terminals are marked B1, B2 and B3 and
shall be used when connecting and external by-pass contactor. This will
enable the integrated protection funcitons also when the softstarter is
by-passed.

External keypad (option)

An external keypad is available as option. The keypad can be mounted on
a panel door for example to view/control the softstarter without
opening the door. The keypad can also be used to copy parameters
betweens different softstarters.

Fieldbus communication

The PST Softstarter has a built-in interface on the front for
connection of the ABB FieldBusPlug used for fieldbus communcation.
Through this interface it is possible to control the softstarter,
achieve status information, up-and down load of parameters. The
interface between the softstarter and the FieldBusPlug is always the
same. Independently of PST Softstarter size or delivery date it is
possible to connect to any fieldbus protocol later on since this is
defined in the FieldBusPlug itself. Available protocols are
AS-Interface, DeviceNet, Profibus Dp, Modbus-RTU and CANopen. To
connect the PST Softstarter to a fieldbus system.

Torque control

The default setting is a normal voltage ramp but it is possible
to select torque ramp. With the torque control function it is possible
to start and stop motors with a more linear acceleration than when
using the normal voltage ramps.
During start this can be used to reduce the wear on the equipment driven by the motor.
During stop, controlling the torque is especially useful for pump
applications where voltage ramps can lead to a sudden torque drop which
may result in water hammering and pressure surges. Torque control will
keep these problems to an absolute minimum.

Torque limit

With the torque limit function enabled, the torque can never exceed a
set value during start. This will minimize stress and wear on the
equipment driven by the motor.

Analog output

With the PST (B) softstarter it is possible to have analog output
signals to be used as input to a PLC or an analog meter. The output
signals can be selected to be for instance the current of the motor,
main voltage, active power or the temperature of the motor. The
terminals used for analog output are also used for PTC protection, so
only one of these functions can be used.
