HMI (Human Machine Interface)
The display of the PST gives you information presented in plain words
in required language. You can choose between 14 different languages,
on the display you get all the information you need to set up, adjust
and trouble-shoot.
The PST employs the same basic user concept as today’s advanced
mobile telephones. Using the four buttons on the keypad, you can eas-
ily adjust your own start and stop profile and motor protection
functions for any type of application. There are standard settings for
many common applications including pumps, conveyors, fans, mixers
and compressors for quick and easy set up.
All of this makes the PST extremely easy to handle.
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
function 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.
Coated PCBs
The PST(B) softstarter can be ordered as a version with coated PCBs.
This coating can extend the lifelength of the PSBs in for instance waste
water plants where corrosive acids and gases may exist.
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 an extra set of three terminals on the line
side. The terminals are marked B1, B2 and B3 and shall be used when
connecting an external by-pass contactor. This will enable the integrated
protection functions also when the softstarter is by-passed.
External keypad
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 parame-
ters between different softstarters.

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 applica-
tions 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 equip-
ment driven by the motor.
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.
Fieldbus communication
The PST Softstarter has a built-in interface on the front for connection
of the ABB FieldBusPlug used for fieldbus communication. Through this
interface it is possible to control the softstarter, achieve status informa-
tion, up- and down load of parameters. The interface between the soft-
starter 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. Avaliable
protocols are DeviceNet, Profibus DP, Modbus-RTU and CANopen. To
connect the PST Softstarter to a fieldbus system you need the acces-
sories described on page 31 to 34 as well as specific software for PLC
set-up, which is available at
pages.
