Video: Why does ATS22 softstarter trip on SnbF and this code cannot be cleared?


28 September 2021

SnbF Fault occur on Altistart 22

Product Line:
Altistart 22


Exceeded number of starts allowed within a specified time period.

SnbF indicates that too many starts were attempted within a time period based on the settings for parameters Snb (number of starts) and SLG (starts period).  The soft start can be reset after the "starts period" has timed out. Control power needs to be applied for the control board to timeout.  Another option is to set parameter Snb to OFF and then cycle power to the ATS22. The fault code SnbF will clear.  Snb should then be set to the desired "number of starts" for the application.
