This chapter describes the softstarter in general,

specifications as well as available accessories and spare

parts.

 2YHUYLHZ

The PST softstarter is a microprocessor-based softstarter

designed with the latest technology for soft start and soft

stop of squirrel cage motors. The softstarter has several

advanced motor protection features as standard.

The softstarter is designed to be used with or without a by-

pass contactor except for the larger sizes,

PSTB370...1050 where the by-pass contactor is

integrated. In an emergency case, it is possible to start the

motor DOL with this contactor (mind the ratings).

The keypad on the front is designed to be as user-friendly

as possible, with a clear text display. It is possible to

choose between ten user languages.

The softstarter can be controlled in three ways:

• Hardware inputs control

• Keypad control (local)

• Fieldbus communication interface

The integrated fans for cooling are operated only during

ramping (start/stop) and when the temperature of the heat

sink is too high. The temperature is monitored by a

thermistor.

Only one type of control method can be enabled

simultaneously.

Default selection is hardware inputs control.

Keypad control has the highest priority and overrides the

other control methods.
