Chapter 2 - Quickstart
This chapter is a short guide on how to connect, configure and start
the softstarter in the quickest and safest way.
Warning!
Mounting and installing the softstarter shall be done in accor-
dance with local laws and regulations and must be performed
by authorized personnel only.
Do not change any parameters in the Service Settings menu.
2:1 Connection
1. Mount the softstarter according to Chapter 4 “ Mounting” .
2. Be aware of the ambient temperature.
Derating is required above 40 °C (104 °F). See Chapter 3 for
more information.
3. Connect the main circuit: terminals 1L1 - 3L2 - 5L3 to the line
side and terminals 2T1 - 4T2 - 6T3 to the motor side.
4. Connect the control voltage: terminals 1 and 2
(100-250V 50/60Hz).
5. Connect the functional ground: terminal 3.
The wire shall be as short as possible, and be connected to the
mounting plate.The mounting plate should also be grounded.
6. Connect the start/stop circuits: terminal 4, 5, 8, 9 and 10 accord-
ing to Figure 2.
7. Verify that the main and control voltage corresponds to the
softstarter ratings.
8. Switch on the control voltage.
9. The green “Power on” LED should be lit and the LCD should
appear as shown in Figure 3.

2:2 Configuration
1. Enter the Application Setting by pressing the left selection key twice.
Press Select using the left selection key.
2. Select the appropriate type of load by using the navigation keys.
3. Press Store Set and Nex t to continue or Back to previous parameter
using the selection keys.
4. Set Ie (motor FLA) using the navigation keys.
In Line connected = rated motor current
Inside Delta connected = 58% of the rated motor current. For
example, if the soft starter is connected in line with a 100A motor, Ie =
100A. If the softstarter is connected inside the delta of a 100A motor, Ie
= 58A.
5. Press Store and Next to continue or press Back to access the previous
parameter.
6. Set the required overload class using the navigation keys.
7. Press Store and Next to continue or press Back to access the previous
parameter.
8. If an external by-pass contactor is used set Ext ByPass to Yes using the
navigation keys. (PST30...300 only).
9. Press Store and Next to continue or Back to previous parameter using
the selection keys.
10.Select Yes if ready or Tune Set if ramp times, initial voltage, current
limit etc. need to be adjusted.
2:3 Start of the motor
1. Switch on the main voltage.
2. Give a start command to the softstarter.
(To start the softstarter from the keypad, enter the LOCAL CONTROL
menu, select Start/Stop and press Start . The motor must be stopped
before leaving this menu.)

Chapter 3 - Description
This chapter describes the softstarter in general, specifications 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 ten different languages
(default is English).
The softstarter can be controlled in three ways:
• Hardware inputs
• Keypad control (local)
• Fieldbus communication interface
The integrated fans for cooling are operated only during ramping (start/stop) and
when the temperature 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.
Keypad control has the highest priority and overrides all other control methods.
