3 Mounting

The PSTX softstarters has different sizes that you can install with M6

bolts, or bolts with the same dimension and strength.

1. Find the correct drawing with dimensions for your softstarter

and make sure that you have the correct drilling plan.

Drilling plan is also printed on the box.

2. If the softstarter is installed in an enclosure, make sure that the

enclosure size is not smaller than the minimum recommended.

Select the size from the applicable table for IEC or

.

3. Make sure that the distance to the wall and the front, and the

installation angle meet the requirements.

4. Make sure that there is free ow of air through the product.

5. You can remove the HMI and use it as a remote control. Drill a hole

where you want to install the HMI. Use RJ45 cable between the HMI

and the softstarter. The maximum cable length is 3 m.

Roll together the remaining cable to prevent blockage of the door.

Use the provided cable or another non shielded RJ45 cable.

Shielded cables should not be used.

Risk of damage to property. Make sure that no liquids, dust or

conductive parts can go into the softstarter.

If you do not obey these instructions, this can cause the softstarter to

become overheated or not operate correctly.

4 Connection

This product is carefully manufactured and tested but there is a risk

that damage can occur from such as shipment and incorrect operation.

Obey to the procedure below during initial installation:

Hazardous voltage: Will cause death or serious injury. Turn off and lock

out all power that supply this device before you start work on the

equipment.

Mounting and electrical connection of the softstarter must be made by

authorized personnel and in accordance with existing laws and

regulations.

Apply the control supply voltage to make sure that the by-pass relays

are in open position before you connect the softstarters PSTX30...

PSTX170 to operational voltage for the rst time. If not, the equipment

can start accidentally.

ABB personnel must obey to the ABB CISE 15.4 instructions.

1. To mount the softstarter, refer to Chapter 3 “Mounting”.

2. Connect the main circuit: terminals 1L1 - 3L2 - 5L3 to the line side and

terminals 2T1 - 4T2 - 6T3 to the motor side. Use wire connection for

PSTX30...105, see Figure

EN

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...PSTX1250, 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.

8. Switch ON the control supply voltage, terminals 1 and 2.

9. Congure applicable parameters given in chapter 6,

Softstarter settings.

10. Switch the operational voltage to ON.

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.

Faults

High current

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
