Issue:
Current (amp) range for the ATS48 parameter "In", Nominal Motor Current.

Product Line:
Altistart 48 ATS48

Environment:
All models

Cause:
Using an undersized motor on the ATS48

Resolution:
The In parameter range is .4 - 1.3 times the soft starter amp rating.  This is typically set to the motor nameplate Full Load Amps and is used by the ATS48 for motor overload protection.  If the motor FLA is below the range, then external overload protection is required.
