Capacitors for power factor compensation are not allowed between the
softstarter and the motor, since this can cause current peaks which can
damage the thyristors in the softstarter. If you use such capacitors, they
must be connected on the line side of the softstarter.
3.
Connect control supply voltage to terminals 1 and 2.
08
4.
Connect terminal 22 to the functional earth.
09
The earthing is not a protective earth, it is a functional earth.
The earthing cable must be as short as possible. Maximum length 0.5
m. The earthing cable must be connected to the mounting plate, which
must also be earthed.
5.
Look at the diagram and connect the start/stop circuits: terminal 13,
14, 18, 19 and 20/21, with the internal 24V DC terminal. When using
internal 24 V DC (terminals 20 or 21), the terminals 18 and 19 should
be connected to each other.
10
Terminal 15, 16 and 17 are programmable inputs for purposes such as
reset, slow speed forward, slow speed reverse, stand still brake etc.
For usage of external supply see 1SFC132081M0201 - Softstarters
Type PSTX30...PSTX370, Installation and Commissioning Manual
available on: http://www.abb.com/lowvoltage
Use 24V DC only when you connect terminal 13, 14, 15, 16 and 17.
Other voltages can cause damage to the softstarter and the warranty
will no longer be valid.
6.
Connect terminals 4, 5, 6, 7, 8, 9, 10, 11 and 12 to use the signal
output relays. These are potential free contacts for maximum 250 V
AC, 1.5 A AC-15 and 30 V DC, 5 A DC-12.
7.
Check that the operational voltage and control supply voltage
correspond to the softstarter ratings.

Built in Modbus RTU
The PSTX softstarter has an RS485 physical interface (terminals 23 and 24),
that can be connected to external devices which have support for RS485 based
communication. Through this interface it is possible to control the softstarter,
retrieve status information and upload and download parameters. The softstarter
has a Modbus RTU slave implemented via the RS485 interface.
See Figure 1.
PTC/PT100 temperature sensor input
The softstarter has input terminals for PTC and PT100 elements (terminals
25, 26 and 27). Please note that both PTC and PT100 cannot be used at
the same time. See Figure 1.
Analogue output
The softstarter has one output for a configurable analog output signal
(terminals 29 and 30). The load resistance is maximum 500 ohm for current
output and minimum 500 ohm for voltage output. See Figure 1.

The motor has been overloaded because of too high current over
a certain time. Check starting conditions and EOL settings.
Locked rotor protection
The motor is running stiff. A damaged bearing or a stucked load
could be possible causes. Check the load and the motor.
Phase reversal protection
The phase sequence is not correct. Change the phase sequence
on the line side to L1-L2-L3.
Current imbalance
protection
Current imbalance between the phases. Restart the motor and
check the main currents and voltage.
Over voltage protection
The main voltage is too high. Check the main voltage.
Under voltage protection
The main voltage is too low. Check the main voltage.
Earth fault protection
Equipment protection. In a symmetrical three phase system, the
sum of the instantaneous line currents is equal to zero. Earth
fault indicates if the sum differs more than a settable value. This
can indicate a serious condition of the motor.
Voltage imbalance
protection
Voltage imbalance between the phases. Check the main voltage
and restart the motor.
Voltage outputs protection
The 24V voltage outputs has been overloaded or shorted. Check
the connections
External thermal sensor PT100 protection
The external thermal sensor has detected a temperature higher
than the trip level. Check the root cause of the over heating.
External thermal sensor PTC protection
The external thermal sensor has detected a temperature higher
than the trip level. Check the root cause of the over heating.
Power factor underload
protection
The power factor has fallen below the normal level.
Current underload
protection
The motor current has fallen below the settable value. Check that
the motor current parameter (Ie) is set correctly.

protection
Programmable digital input can be used in combination with
external device/sensor to provide to the customer the possibility
of handling own defined protection.
Too long current limit
protection
The time at current limit has exceeded the set value. The starting
condition is too heavy for the set current limit. Check starting
conditions and parameters.
By-pass open protection
By pass contactor or relay does not close when reached TOR.

Faults
Warnings
Voltage to one or more phases missing. Check that the mains
are connected and that no line contactor or breaker is open.
High current fault
A fault current, higher than 8 times the softstarter rated current,
has occurred. Check the circuits including the motor for any
insulation fault phase to phase or earth fault.
Low supply voltage fault
Too low control supply voltage on terminals 1 and 2. Check for
voltage dips or interruptions.
Bad network fault
Excessive disturbances in the operational supplying network.
Check for harmonics or frequency disturbance in the supply
network.
Thyristor overload fault
The thyristors are overheated. Check the starting conditions and
the fans. Increase current limit if needed. Let the thyristors cool
down before restart.
Short circuit fault
A thyristor is shorted. Contact ABB sales office for service.
Shunt fault
The softstarter cannot stop the motor due to internal short
circuit. Contact ABB sales office for service.
Current imbalance warning
