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.
Check that you have the correct product in regards to operational
voltage, 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
