Issue:
Can an unloaded motor be tested with an ATS22 Softstarter?
Product Line:
Altistart 22
Environment:
Shop tests, unloaded motor
Cause:
Testing the ATS with an unloaded motor, usually trips the ATS22 with SSCr.
Resolution:
Yes.
After entering the correct motor data, set the following parameters:
- LAC = ON
- t90 = Factory 30 change to 10. ( Due to No Load connected and monitor ramp acceleration. This value to be changed back or increased when in the field under actual start-up )
- ILt = Factor 350 change to 200% for Shop Testing. ( Value to be changed in the field if Current Limit trips out )
- tLS = Factory 15s change to 60s for Shop Testing. ( Changed back to 15s after completion of testing )
- ACC = Factory 10s change to 60s for Shop Testing. ( Changed back to 10s after completion of testing )
- SSC = Factory On, changed to oFF. ( Using Voltage control vs. Torque )
- ItH = On. ( Factory is On)
