Thyristor Ol Out 0; Curr Underload Level 0.4; Curr Underload Trip Time 0; Curr Underload Delay Time 0 - ABB PSTX30 Installation And Commissioning Manual

7.16.3 Thyristor overload warning
A warning signal will be given if the thyristor temperature
has exceeded the settable warning level. The warning
says that the softstarter is approaching overheating value
and will tripp if the heat is not removed.
Check the starting conditions and the fans.
Increase current limit if needed.
Thyristor overload warning is configured with the
following parameters:
Parameter
20.08 Thyristor OL out
20.09 Thyristor OL
7.16.4 Current underload warning
A warning signal will be given if the line current decreases
below the settable value during continuous operation.
Check that the motor current parameter (Ie) is set
correctly.
Current underload warning is configured with the
7
following parameters:
Parameter
21.01 Curr underload level
21.02 Curr underload trip time
21.03 Curr underload delay time
21.04 Curr underload out
21.05 Curr underload
7.16.5 Power factor underload warning
A warning signal will be given if the power factor is below
the settable warning level.
Power factor underload warning is configured with the
following parameters:
Parameter
21.06 Pwr factor underload level
21.07 Pwr factor underload trip time
21.08 Pwr factor underload delay time
21.09 Pwr factor underload out
21.10 Pwr factor underload
