7.20.2 Line contactor close time
This feature allow time for the line contactor to close
before the Softstarter assumes that it has correct 3 phase
supply.
This is useful to avoid timing problems that can lead to
unnecessary trips on for example Phase loss protection.
Line contactor close time has these parameters:
Parameter
28.02 Line contactor close time
7.20.3 Limp mode
This feature allows the PSTX to operate with only 2
controlled phases in case of short circuit of 1 set of
thyristors. Replace the thyristors when this warning is on
(if the short circuit warning is enabled).
Limp mode has these parameters:
Parameter
7
28.42 Limp mode
7.20.4 Start without start command
This feature can be used for a customer that would like
to use the Softstarter in the same way as a contactor is
used, i.e. as soon as the control supply to the Softstarter
is turned on the Softstarter will automatically start the
motor. No wiring of start and stop signals is necessary.
Start without start command has these parameters:
Parameter
28.04 Start without start command

Description
Allow time for line contactor to close. Sets
the time between start signal and beginning
of diagnostic measurements.
Description
If this parameter is enabled and
if a thyristor is shorted, there is
an automatic transition to limp
mode.
Description
Starts the motor without needing
an external start command.
