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.
4. Connect terminal 22 to the functional earth.
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.
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...PSTX570, 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.

You can be exible when you connect the PSTX softstarter,
but following the previous steps will enable operation of the PSTX
softstarter. You can nd an example of a full installation in the graphics
section. The rst one uses fuses and contactors and the second one
uses a circuit breaker.
Refer to the timing diagram graphics 13 for the basic behaviour of
PSTX softstarter.
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.

7 Troubleshooting
Depending on PSTX Softstarter conguration, different events may be signalled on the display. See Event list Table 7.1.
Table 7.1: Event list
Description
Protections
Electronic overload The motor has been overloaded because of too high current over a
certain time. Check starting conditions and EOL settings.
Locked rotor The motor is running stiff. A damaged bearing or a stucked load
could be possible causes. Check the load and the motor.
Phase reversal The phase sequence is not correct. Change the phase sequence
on the line side to (L1→L2→L3).
Current imbalance Current imbalance between the phases. Restart the motor and
check the main currents and voltage.
Current underload The motor current has fallen below the settable value. Check that
the motor current parameter (Ie) is set correctly.
User dened protection Check the external sensor.
Earth fault
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.
Over voltage The mains voltage is too high. Check the mains voltage.
Under voltage The mains voltage is too low. Check the mains voltage.
Voltage imbalance Voltage imbalance between the phases. Restart the motor and
check the mains voltage.
PT100 protection The external thermal sensor has detected a temperature higher
than the trip level. Check the root cause of theover heating.
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 The power factor has fallen below the trip level.
Too long current limit The time at current limit has exceeded the set value. The starting condition is too heavy for the set current limit. Check starting condi-
tions and parameters.
Bypass open fault The bypass contactor or relay does not close when reached TOR.
Contact ABB sales ofce for service.
Fieldbus communication
failure There is a communication disturbance between the softstarter and PLC.
24V output Check the hardwire inputs.
HMI failure There is communication disturbance between the softstarter and
the HMI. Check the connection to the HMI.
Extension IO failure There is communication disturbance between the softstarter and
the extension I/O module. Check the connection to the I/O module.
Max number of starts The settable maximum number of starts per hour has been
reached.
Auto-restart time-out The time between trip and auto-restart attempt exceeds setting.
Too long start time It takes too long time to soft start the motor. Check starting condi-
tions and current limit setting.
Frequency range The frequency has been outside the allowed range longer than the
allowed time.

A fault current, higher than 8 times the softstarter ratings, has
occurred. Check the circuits including the motor for any insulation
fault, phase to phase fault, or earth fault.
Phase loss Voltage to one or more phases missing. Check that the mains are
connected and that no line contactor or breaker is open.
Heat sink overtemperature
The heat sink temperature is too high. Check the starting conditions
and the fans. Increase current limit if needed. Let the softstarter
cool down before restart.
Bad network quality Excessive disturbances in the operational supplying network. Check
for harmonics or frequency disturbance in the supply network.
Shunt fault The softstarter can not stop the motor due to internal short circuit.
Contact ABB sales ofce for service.
Low supply voltage Too low control supply voltage on terminals 1 and 2. Check for volt-
age dips or interruptions.
Thyristor overload
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 thyristor One or several thyristors are shorted. Contact ABB sales ofce for
service.
Open circuit thyristor One or several thyristors are not conducting. Contact ABB sales
ofce for service.
Unspecied fault Internal fault in the softstarter. Disconnect and reconnect the supply
voltage. If fault remains, contact ABB sales ofce for service.
Invalid ID A valid softstarter ID has not been set.
Faulty connection Motor is connected in a faulty way.
Faulty usage It is not allowed to use the functions jog, motor heating and stand
still break when the softstarter is connected inside delta.

Warning
Current imbalance Current imbalance between the phases. Restart the motor and
check the mains currents and voltage.
Current underload The motor current has fallen below the warning level. Check that
the motor current parameter (Ie) is set correctly.
Fan failure One or several fans are not working properly. Risk of overheating.
Contact ABB sales ofce for service.
EOL warning The motor is nearly overloaded because of too high current over a
certain time. Check starting conditions and EOL settings.
Locked rotor
The motor current has exceeded the warning level. The motor is
running stiff. A damaged bearing or a stucked load could be pos-
sible causes. Check the load and the motor.
Over voltage The main voltage is nearly out of range (x - x V)
Under voltage The main voltage is nearly out of range (x - x V)
Power factor underload The power factor has fallen below the warning level.
THD(U) THD has exceeded the warning level. Check quality of the network.
Thyristor overload
The calculated thyristor temperature has exceeded the warning
level. Check the starting conditions and the fans. Increase current
limit if needed.
Voltage imbalance Voltage imbalance between the phases has exceeded the warning
level. Check the mains voltage.
Short circuit There is an internal short circuit and the softstarter is running in limp
mode. Contact ABB sales ofce for service.
EOL time-to-trip The predicted time before EOL trip has fallen below the warning
level.
Phase loss Voltage to one or more phases missing. Check that the mains are
connected and that no line contactor or breaker is open.
