ABB soft starter PSE quick use method

The quickest way to wire, configure and start a soft starter. The production and detection process of this equipment is very rigorous, but the risk of damage is due to abnormal handling during transportation to a certain extent. Therefore, the following procedures should be followed during the initial installation.

Warning: Installation, electrical commissioning and setting of the soft starter must be carried out by an approved technician in accordance with the relevant installation regulations.

Warning: ABB soft starter PSE18 to PSE370 with inner triangular connection is at risk of being discarded and serious damage.

Warning: Prior to the initial connection of PSE18 to PSE170 to the grid voltage rating, the control supply must be switched on to ensure that the bypass relay is in its open position, which will effectively prevent the equipment from being misstarted during wiring.

Note: Dangerous voltage. Could result in death, injury or serious injury. All power must be turned off before the operation can proceed.

Warning: Paid capacitors are not allowed to be connected between the soft starter and the motor because they can generate a peak current and damage the device's thyristor. If such capacitors are used, they should be connected to the incoming side of the ABB soft Starter PSE.

Sign I: This connection is not for protection grounding, but for grounding function. The ground wire should be as short as possible, up to 0.5 m. The ground wire should be connected to the same ground mounting plate.

Warning: Do not connect external power terminals 9, 9, 10, 11, 12, 13 and 14. If connected to other voltages, the soft starter and expiration date may be destroyed.

Warning: The same external voltage (up to 24V DC or 250V AC) must be connected to output relay terminals 3, 4, 5, 6 and 7. If connected to another voltage, the soft starter and expiration date may be broken.

Note: Two-phase soft starters, one of which always carries a voltage. So please do not touch the terminal when the power is on. Even when the device is stopped, the output terminal still has a voltage, so special care must be taken to avoid serious injury.

1. Please pay attention to the ambient temperature, which needs to be lowered above 40 degrees Celsius.

2. Terminal 1L1, 3L2 and 5L3 are connected to the power supply.

3. Terminal terminals 2T1, 4T2 and 6T3 are connected to the motor.

4. The power supply voltage of the control loop is connected to terminals 1 and 2 (100-250V 50/60Hz).

5. The connection grounding function is on terminal 14, the nearest connection point to the soft starter.

6. If necessary, start, stop and other control circuits, including analog outputs, can be connected to terminals 8, 9, 10, 11, 12 and 13. They are powered by an internal 24V DC without the need to provide external power.

7. When using the signal output relay, connect terminals 3, 4, 5, 6 and 7. These dry contact relays ac-15 can reach A load of 250V AC, 1.5A. Make sure you are using the same pressure level on these terminals.

8. Switch on the control power voltage Us, terminals 1 and 2.

9. Configure the parameters of rated current Ie according to the diagram below.

10. Switch on the working voltage Ue of the main circuit and the green Ready LED will be bright.

11. Issue starting instructions to the soft starter.

◆ The thyristor is placed in L1 and L3 phases to control the voltage of the motor, and L2 phase is directly connected to the motor;

◆ Voltage control or torque control can be arbitrarily selected during starting and stopping process;

◆ With motor protection such as underload and rotor lock-in.

The front keyboard is easy for users to operate, with clear icon display. ABB soft starter can be controlled in two ways:

◆ Terminal input control;

◆ Fieldbus control.

Only one control mode can be selected. The default choice is terminal input control.

The cooling fan only works during the soft starter (start/stop) process and when the temperature of the radiator is too high. Thermistor monitors the temperature.

The ABB soft-starter type must be checked for accuracy, including parameters such as rated operating voltage, control supply voltage and motor rating (see equipment logo and connection diagram below).

PSE18... The PSE370 soft starter operates at a wide range of voltages.

◆ Rated working voltage: 208-600V /AC;

Rated power supply voltage: 100 to 250V/AC.

Warning: this equipment can only be used within the specified rating value. The ambient temperature and altitude must be taken into account. The altitude above 40℃ and 1000 meters should be lowered.
