74 S611 Soft Starter MN03902011E—May 2012 www.eaton.comExisting Installations ChecklistExternal circuit components issues● 120 Vac control power undersized and/or failed● Isolation contactors open or damaged● Mains power faulty● Load disconnected● Load failure● Line/Load/Control circuits not restored after componentreplacementVerification of recent maintenance functions● All disconnected connections restored● Isolation devices restored to proper operating positions● Proper selection of replacement components● Verify suitability of added or modified components tocircuitryFault code verification● Use of test equipment to confirm/refute validity of faultcode● Determine if the fault can be reset● Determine if the fault is continuous or intermittent● Note operating conditions at time of fault if possibleCommon fault codes● FC15—Power pole over temperature● FC31—Voltage imbalance● FC33—Jam● FC20—Overload● FC35—Temperature sensor● FC17—SCR not firing● FC18—Shorted SCR● FC21—Mains AC voltage loss● FC8—Voltage zero cross lostGeneral Information120 Vac control power—terminal block connections● Run Enable 24 Vdc applied to terminal “Permissive”.This 120 Vac input must be maintained continuously duringRUN● START Command enable from terminal block Novoltage applied to Network terminals. When a 120 Vacsignal is applied to the Network terminal, START controlfrom the terminal block will not be recognized● START Command with 120 Vac applied to terminal“Permissive”, apply 120 Vac to terminal “Start”. Thesignal requirement is momentary, but maintained isacceptable. Terminals “Permissive” and “Start” may betied together for two-wire control START/STOP commands● STOP Command Remove 120 Vac from terminal“Permissive”. Terminals “Permissive” and “Start” may betied together for two-wire control START/STOP commands● Wire size, minimum—14 AWG (single conductor) to allterminal block connections. Wire should have no standsmissing or damaged during wire stripping. The use ofterminal ferrules is recommended to maintain connectionintegrity● Control power supply requirements– Must meet or exceed steady state and inrushcapacity requirements– Steady state (sealed) A–D Frames = 85 VA, 120 Vac– Outrush A–D Frames = 600 VA, 120 Vac for 50 msminimum– Steady state (sealed) E–F Frames = 115 VA, 120 Vac– Outrush E–F Frames = 1200 VA, 120 Vac for 50 msminimum– Minimum supply voltage 120 Vac measured at theterminal block– Maximum allowable voltage drop measured at theterminal block = 5 Vacwww.comoso.com
