S611 Soft Starter MN03902011E—May 2012 www.eaton.com 27Thermal OverloadThe S611 soft starter features an electronic motor overload protection feature. It is designed toprotect the motor and power wiring against overheating caused by operating at excessive currentlevels for extended periods of time.Entering the motor’s full load current rating, using the Motor FLA parameter programs theoverload. The Motor FLA is settable from 50% to 100% of the S611’s rated current (frame size).The overload’s trip class is set using the Trip Class parameter in the Protection menu. Editing theTrip Class parameter to “OFF” will disable overload protection.Additional details on the thermal overload can be found in Appendix B—Protection.ProtectionIn addition to motor overload protection, the S611 has many programmable features designed toprotect the motor as well as the soft starter itself.● Incoming line phase reversal, loss, imbalance, over voltage, and under voltage trips● Three overcurrent trip levels● Stall and jam tripsFor troubleshooting purpose trips are recorded, as they occur, in the S611’s fault log.Apply the mains voltage and verify that no fault is present. The S611 indicates most faults with afault code in the alphanumeric display and by illuminating the corresponding mode and Protection/Operation (P/O) LEDs. When a fault is indicated, the dedicated Fault P/O LED will be illuminated.4. The fault history may be displayed by pressing the Fault Log button.A Phase Reversal fault is a likely candidate on new installations. It can be remedied by eitherchanging the Phase sequence P/O LED from ABC to ACB or removing mains power andswitching the incoming line connections at L1 and L2 of the S611.Fault CodesFault FCUser InterfaceMode LED P/O LED DisplayWatchdog firmware 3 None None F.03FRam 5 None None F.05User interface com failure 6 None None F.06Flash CRC 7 None None F.07Zero volt cross lost 8 None None F.08Comm lost port A 9 None None F.09Comm lost port B 10 None None F.10Pole over temp 15 None None F.15Bypass dropout 16 None None F.16SCR not firing 17 None None F.17Shorted SCR 18 None None F.18Instantaneous SCR overcurrent 19 None None F.19Motor overload 20 Operation Motor FLA F.20Mains loss 21 Protection Under voltage (V) F.21Under voltage 22 Protection Under voltage (V) F.22Over voltage 23 Protection Over voltage (V) F.23www.comoso.com
