Application
The PST range is a microprocessor based softstarter designed with the latest
technology for soft start and soft stop of motors. The PST Softstarter has several
advanced motor protection features as standard. The four button key pad and the
logic structure of the menu makes the installation, commissioning and operation
easy. It is possible to choose between 12 different languages.
The PST Softstarter can be used with or without a by-pass contactor. The larger
sizes, PSTB370 – PSTB1050, include a built-in by-pass contactor.
The PST Softstarter can be selected according to the rated motor power in
normal duty applications like pumps, compressors, elevators, escalators, short
conveyor belts and bow thrusters.

Digital display
Your business is going global. Shouldn't your motor control go global, too? The
PST display gives you information presented in plain words — in your language.
You can choose between almost a dozen languages including English, German,
Italian, Chinese, Finnish, Swedish, French, Spanish, Dutch, Russian, Turkish
and Portuguese. 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.
At any time, you can read output current, output voltage, number of starts, total
run time and motor temperature on the display. If a fault should occur, this is also
indicated on the display. The fault messages are presented in clear text in the
selected language.

Type PST
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 profi le 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.
You can also set the advanced warning parameters to allow potential problems to
be identifi ed before real problems occur. A password protection function is available to prevent unauthorized changes to the programming.
Remote four button keypad
This optional remote keypad is an extended HMI (human-machine interface) for
6
all PST(B) softstarters. The remote keypad allows you to access all functions from
the PST(B) on the outside of the enclosure door.
The interface/display is exactly the same as the one on the softstarter (working
in parallel with the one on the product). Used as a handheld device, it is easy to
set up parallel softstarter units as you can copy data from one softstarter unit and
download to another.
The keypad kit includes all necessary details for assembling: 3 screws, 10 ft.
communication cable, installation instructions and a drilling plan.
The keypad has the following approvals: UL Type 1, 12, Indoor 4/4X.
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 fi nd 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 fault protections or 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 (PSTB370 – PSTB1050), there is an integrated ABB AF
contactor. This gives you advantages in terms of cost-saving, (less investment in
fans, cables, time), space saving (more compact soft starter; no fan that takes up
space), 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.
For the smaller PST below 370A, which are not equipped with built-in contactors,
the units have double connections for the main terminals on the line side. The extra terminals are used to connect an external by-pass contactor in order to enable
the integrated protection functions.

Fieldbus communication
The PST Softstarter has a built-in interface on the front for connection of the ABB
FieldBusPlug used for fi eldbus communication. Through this interface, it is possible to control the softstarter, achieve status information, upload and download
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 fi eldbus protocol later on since this is defi ned in the FieldBusPlug itself. The following protocols are currently available: AS-I, DeviceNet
and Profi bus DP. To connect the PST Softstarter to a fi eldbus system, you need
the accessories described on pages 6.33 to 6.34 as well as specifi c software for
PLC set-up, which is available on the ABB web site; see the Resources section
at the bottom of the Softstarter product page at www.abb-control.com/products/
softstarters.htm.
