How to Use the Small Motor Test [SST] Function on an ATS480 Soft Starter
Resolution:
The Small Motor Test [SST] parameter is located under Menu 3 [Complete Settings] > 3.3 [Motor Wiring].
This parameter allows the ATS480 to be tested using a small motor. When [SST] is set to YES, phase loss monitoring [PHP] is disabled and Control Mode [CLP] is automatically forced to Voltage Control. This allows the soft starter to start normally when a run command is applied. During the test, the display terminal will indicate [Small Motor Test] SST.
The [SST] parameter automatically resets to NO after a power cycle.
In SoMove ATS480 DTM version 1.1.10.0, the [SST] Small Motor Test parameter is not currently visible. Therefore, this parameter must be changed directly from the ATS480 keypad. At this time, it is unknown whether [SST] will be made available through SoMove in a future DTM version.
