52 S611 Soft Starter MN03902011E—May 2012 www.eaton.comMotor JamWhen the bypass contactors are closed, the S611 monitors the maximum rms value of thethree-phase currents. the unit will trip with a motor jam fault if the jam trip is enabled and themaximum rms value exceeds the trip threshold for the duration of the trip delay.Motor Jam SettingsContactor OvercurrentThe contactor overcurrent trip is active only if the jam fault trip is disabled. When the bypasscontactors are closed, the S611 monitors the maximum rms value of the three-phasecurrents. The unit will trip with a contactor overcurrent fault if the maximum rms valueexceeds four times the catalog FLA for the class dependent trip delay.Motor (Contactor) Overcurrent SettingsSCR OvercurrentThe SCR overcurrent trip is only active if the stall fault trip is disabled. The S611 monitors themaximum rms value of the three-phase currents. The unit will trip with an SCR overcurrentfault if the stall fault is disabled and the maximum rms value exceeds three times the FLAsetting when the start time setting expires.SCR Overcurrent SettingsParameter Set Point Range Step Default NotesTrip threshold OFF, 150–400% ofFLA setting1% 300% Settable from the UIMode O/P LEDProtection Jam trip %Trip delay 1–20 seconds 1 2 seconds Settable from the UIMode O/P LEDProtection Advanced Conf—P.14Parameter Set Point Range Step Default NotesTrip threshold 400% of catalogFLAN/A N/A Not user settableTrip delay N/A N/A Not user settableS611 never trips on overload at catalog FLAS611 is programmed to let overload fault tripfirst at catalog FLAClass = 5 4.5 secondsClass <= 10 9.0 secondsClass <= 20 16.0 secondsClass <= 30 23.0 secondsParameter Set Point Range Step Default NotesTrip threshold 300% FLA N/A N/A Only active if stall is disabledTrip delay N/A N/A N/A Instantaneous rms value at end-of-ramp is usedwww.comoso.com
