Chapter 3 - Description
This chapter describes the softstarter in general, specifi cations and available accessories and
spare parts.
3:1 Overview
The PST softstarter is a microprocessor-based softstarter designed with the latest technology for
the soft start and soft stop of squirrel cage motors. The softstarter has several advanced motor
protection features as standard.
The softstarter is designed to be used with or without a by-pass contactor except for the larger
sizes, PSTB370...1050 where the bypass contactor is integrated. In an emergency, it is possible
to start the motor across the line with the integrated bypass contactor. See Section 3:8.4 for AC3
ratings.
The keypad on the front is designed to be as user-friendly as possible, with a clear text display. It
is possible to choose between twelve different languages (default is English).
The softstarter can be controlled in four ways:
3
• Hardware inputs
• Keypad control (local)
• Fieldbus communication interface
• Remote keypad (option)
The integrated fans for cooling are operated only during ramping (start/stop) and when the tem-
perature of the heat sink is too high. The temperature is monitored by a thermistor.
Only one type of control method can be enabled simultaneously.
Default selection is hardware inputs.
Information!
Keypad control has the highest priority and overrides all other control methods.
3:2 Functions
The PST softstarter has several integrated protection and warning functions. Almost any type of
fault can be detected and displayed.
All available protections, warnings and fault indications are listed below.
Start/Stop functions
• Start ramp
• Stop ramp (also called soft stop or decel)

5:3.2 External keypad
An external keypad for door mounting can be connected to the softstarter. A 3-meter cable including both the
serial communication and the power supply to the keypad makes the connection.
The external keypad can also be used for transferring parameters from one softstarter to another during
commissioning (temporarily handheld). Note that NEMA 4/4X cannot be achieved when the keypad is not
mounted.
When thee external keypad is used, both keypads will work in parallel but the softstarter keypad always has
the highest priority if the keys on both units are pressed simultaneously.

This chapter describes how the human-machine interface (keypad and display) works.
2
6:1 Overview
6:1.1 Application
The Human-Machine Interface is used for several purposes such as programming the softstarter, i.e setup of
inputs and outputs, protection functions, warning levels, fi eldbus communication, etc. The HMI is also used for
3
4
1
monitoring, local control and receiving status information from the softstarter.
6:1.2 Design
The HMI consists of:
• Status indication LED indicators
• LCD display
• Selection and Navigation keys
The LED indicators work as follows:
LEDColorDescription
Power onGreenControl voltage connected
FaultRedIndicates faults
ProtectionYellowIndicates protective function has activated
When a Fault or Protection LED is activated, the LCD displays the actual fault or protection.
The keypad is based on the same user concept as today’s mobile phones.
The LCD contains two rows with 20 characters each.
The top row presents various information depending on its state. The bottom row indicates which function is
currently selected.
A scrolling icon indicates what parameter or setting value is possible to change at the position.
The Selection keys normally have more than one function, such as selecting, changing and storing parameters.
See the text on the bottom row of the LCD.
The Navigation keys are used for navigating through the various menus to the desired setting.
When selecting from a list, the scrolling is done in a closed loop fashion.
The functionality of the keypad is illustrated by the following example:
Changing the rated motor current ( Setting I

Settings can be done in three different ways:
• Keypad
• Fieldbus communication
• External keypad (optional)
With the keypad, settings can be done as individual parameter settings or by selecting pre-
defi ned parameters for different applications.
The unit has one complete set of parameters but some parameters have extra settings (i.e.,
sequence start). All default parameters are stored in the unit in case a full reset to default values
is required. When the fi eldbus communication is selected, most parameters can also be modifi ed
from this interface.
!
The motor may start unexpectedly if there is a start signal present when doing any of the actions
listed below:
• Switching from one type of control to another (fi eldbus control / hardware control)
• Re-programmming the programmable inuts
• Reset all Settings (programmable input set to Enable).
Caution!

Fieldbus communication (option)
8:1 Overview
The PST softstarter has an interface on the front for connecting the ABB fi eldbus plug is
used for fi eldbus communication. Through this interface, it is possible to control the soft-
starter, achieve status information, as well as upload and down-load parameters.
The interface between the softstarter and the eplug is always the same. Independent of
softstarter size, it is possible to connect any fi eldbus protocol in the future since the protocol
is defi ned in the eplug itself.
The following fi eldbus protocols are available:
• AS-Interface
• DeviceNet
• Profi bus DP
• Modbus
8:1.1 Required accessories
To connect the softstarter to a fi eldbus system, the following accessories are required:
• Fieldbusplug for appropriate protocol (check that the cable length is suffi cient).
• Connectors for bus connection.
• End plug (some protocols).
• Software for PLC set-up.

Maintenance
This chapter describes the maintenance required for the softstarter. In principle, the product is
maintenance free but some items should be checked regularly.
Do not open the softstarter or touch any live parts when the main and control voltage
is connected.
Caution!
9:1 Regular maintenance
• Check that all mounting bolts/screws are fastened. Tighten if necessary.
• Check that all connections of main, control and supply circuits are fastened.
• Tighten the terminal screws and bolts on the connection bars, if necessary.
• Check that the cooling airways are free from dirt and dust. If required, use pressurised air to clean.
• Check external fi lters. Clean, if necessary.
• Check that the fan is working and rotating freely. The blades should rotate without any resistance and
this can be checked at voltage free state.
• Check the real time clock and adjust if necessary.
In case of a fault or if a fault can not be reset, see Chapter 11, “ Trouble shooting”.

Start/Stop / Init Volt
This parameter makes it possible to set the voltage level where the start ramp begins. If the
initial voltage is set too low, it will cause unneccessary long starting times and unnecessary
heating of the motor.

Start/Stop / Step Down
When stopping a motor using the stop ramp, the speed will not decrease immediately. The
step down voltage function makes it possible to set a level where the motor speed decreases as soon as the stop ramp begins. By using, a more optimized stopping of the motor is
achieved. It is mainly used for pump applications.

10:7 Current limit
Path in menu:
Menu/SETTINGS/Functional Settings/
Start/Stop / Current Lim
It is possible to limit the starting current by using this function. When the current limit is
reached, the output voltage stays stable until the current level falls below the limit, then the
ramping continues.
The starting current must be high enough to make it possi ble for the motor to reach the rated speed. The
lowest pos sible current depends on the performance of the motor and the characteristics of the load.
