3.1 Overview
The PSTX Softstarter has the latest technology for
soft start and soft stop of squirrel cage motors. The
Softstarter has multiple advanced motor protection
features as standard.
WARNING
If using the Rated Operational Voltage U
e
(Phase
/N) as source for Control Supply Voltage U
s
make
sure to not exceed U
s
250V AC,50/60Hz.
Bypass
Softstarter range PSTX30...1250 have integrated bypass
components.
User interface
The keypad on the front has Navigation keys, Selection
soft keys, Start and Stop keys, Local or Remote key,
Information key and a clear information screen. You can
select 15 user languages.
You can control the Softstarter in 3 different ways:
• Hardwire inputs control
• Keypad control (either attached to the Softstarter front
or detached and connected with the cable included)
• Fieldbus communication interface (by built in Modbus,
Anybus module or the FieldBus Plug with adapter)
You can use only one type of control at the same time.
Default selection is hardwire inputs control.
INFORMATION
Keypad control has the highest priority and
overrides all other control methods.
Fans
The integrated fans for cooling will run for 3 min
after each ramp (start/stop) and when the heatsink
temperature is too hot.
For PSTX1050…1250 the fans will run continuously in
TOR. A thermistor monitors the temperature.
