2 Description
The PSE Softstarter is microprocessor-based and designed with the
latest technology for soft starting, and when applicable, soft stopping of
standard squirrel cage motors.
The PSE Softstarter has several features as standard.
• Integrated by-pass.
• Torque control ramp during start and stop.
• Built in Electronic Motor protection.
• Kick start.
• Analog out signal can vary in the range 4 - 20 mA, corresponding
to 0 - 120 percent of set I e (terminals 13 and 14). 100 percent cor-
responds to 17.3 mA.
• Three output signal relays to indicate Top of Ramp (TOR), trip
events (FAULT) and running (RUN).
• Pollution degree 3
The PSE Softstarter can be controlled in two ways:
• Hardwire inputs using terminals 8 and 9, in circuit with terminals 11
or 12.
• Fieldbus communication interface.
1. Check that you have the correct product in regards to operational volt-
age, control supply voltage, rated motor data, and used numbers of
starts per hour.
The PSE18...PSE370 Softstarters operates over wide voltage ranges.
• Rated operational voltage 208 - 600 V AC
• Rated control supply voltage 100 - 250 V AC
The product should only be used within the specified ratings. Be aware
of the ambient temperature and altitude above sea level. Derating is
required above 40 °C (104 °F) and above 1000 m (3281 ft). For more
details see Softstarters Type PSE18...PSE370, Installation and Com-
missioning Manual, Document ID 1SFC132057M0201 available on:
