S611 Soft Starter MN03902011E—May 2012 www.eaton.com 312. With the Fault LED illuminated, the device will not start.Attempt to reset the S611 soft starter by pressing theS611’s RESET button for one second. If the LEDremains illuminated, use the User Interface Module (UI)to determine the Protection Fault LED or fault code andgo to the S611 Fault Codes in Appendix G—Troubleshooting Guide to find the corrective action forthe fault code.3. The Ready LED is illuminated and the S611 soft starteris ready to start. Determine the start source from thetable on Page 30 to aid in determining the appropriatecorrective action. Verify that the permissive inputterminal is at 120 Vac, then start the S611 from theControl Input terminal block, TB3.Note: If connected to a network, starting the S611 fromthe Control Input terminal block (TB3) may isolateproblems associated with the network and not with thesoft starter.4. It is often useful in evaluating a trip condition to notewhen the trip occurs during operation of the S611 softstarter. The operation of the S611 may be categorizedinto the following periods:• The S611 soft starter trips during the START rampand never reaches bypass• The S611 soft starter trips when the bypasscontactors are closed• The S611 soft starter trips during running operationwhile bypass contactors are closed• The S611 soft starter trips after the Stop command isreceived• The S611 soft starter stops sooner than expectedduring a soft stop. If the Soft Stop Time is set toolong for the motor loading (high loads), the motor willbegin to stall when delaying SCR firing reduces thevoltage. The S611 soft starter will detect this stallingdue to the increase in current flow and end the stopimmediately and not indicate any faultsUse the flowchart on Page 32 to aid in determining theappropriate corrective action during the various runphases of operation.Note: If no fault codes are present during an unexpected“trip” of the soft starter, verify that the soft starter didnot receive a STOP command.Detailed information describing fault codes andcorrective action may be found in Appendix G—Troubleshooting Guide.S611 Stopped or FaultedCondition Possible Problem Suggested Corrective ActionReady LED illuminated,no Fault LED• Stop command received• Terminal block wiring not secure• Loss of 120 Vac control power• Transient fault when Reset mode set to AUTO• External control device failure• External mains device failure or trip condition• Control board failure• 120 Vac permissive signal lost—investigate control system• Check control wiring for security• Check 120 Vac power source for correct sizing and circuitconnections• Change Reset mode to Manual to capture fault condition• Inspect external control devices for proper operation• Inspect external devices for condition and proper operation• Possible device fatal errorFault LED illuminated • Protection/Operation parameters not set toproper values• Fault condition exists in mains circuit• Fault not reset from previous trip• Reset mode set to Manual• Determine Fault condition from the Mode LEDs and the faultcode displayed in the alpha numeric display• Adjust Protection/Operation parameter values to preventrecurring fault trips• Correct problems with mains voltages and/or phaseconditions• Attempt to reset fault—the fault will not reset if the faultcondition exists• Set Reset mode to Manual to retain soft starter in faultcondition for troubleshooting.
