20 S611 Soft Starter MN03902011E—May 2012 www.eaton.comControl FunctionsNetwork ControlWhen the S611 is in network control, it is ready to respond tomotor START control commands issued only through thenetwork comms ports A and/or B. It is not necessary toselect either comms port A or comms port B.The comms ports A and B enable complete communicationsbetween the S611 and the network including changingparameters settings, issuing control commands, andmonitoring selected operational values via DeviceNet,Modbus, or PROFIBUS Networks. Comms port A providesModbus motor control commands.Both comms ports may be used simultaneously andindependently configured.Refer to Appendix F for Modbus Network controlinformation.Profibus Network control information may be found in Eatonpublication MN04210003E.DeviceNet Network control information may be found inEaton publication MN04210002E.Local ControlS611 local control consists of Comms Select, Permissive,Start, and Reset 120 Vac control commands to terminalblock 3 (TB3). The S611 cannot be started from the UserInterface Module.Terminal block 3 (TB3) uses four (4) functions to control theS611 soft starter.1. Permissive (run enable)—Must be energized with120 Vac to enable operation of all S611 soft starters byboth local and network control. If power is lost orremoved from Permissive terminal at any time, the unitwill initiate a coast stop, soft stop, or pump stop inaccordance with the setup parameter selections. If theS611 is being controlled from a network, loss of thePermissive signal will initiate a coast stop, soft stop, orpump stop in accordance with the setup parameterselections.2. Start—If 120 Vac is present at the Permissive terminal,momentary application of 120 Vac to the Start terminalwill initiate a voltage ramp or current limit start for theS611 soft starter. Application of 120 Vac may bemaintained.Note: With level sensing control, if 120 Vac is lost orremoved from the Permissive terminal at any time,the unit will initiate a stop in accordance with setupparameter selections. A restart will occur when120 Vac is restored or reapplied if:a) 120 Vac is present on the Start terminal(maintained), and;b) the UI device shows a ready LED (not faulted). Ifthe starter has faulted and the fault conditionclears AND the Auto Reset Mode parameter inthe Operation Mode list is set to AUTO, thestarter will restart.See the Level or Edge Sensing section on Page 21 foradditional details.CAUTIONIf the AUTO Reset mode setting is used with level sensing,CAUTION must be exercised to assure that any restartoccurs in a safe manner. Motor restart may occurimmediately and unexpectedly after any fault condition hascleared.3. Reset—Application of 120 Vac power to the Resetterminal will reset the soft starter after all faultconditions are cleared. If the fault LED is not able to bereset, a fault condition still exists and must be corrected.A reset signal may also be sent from any networkconnection.Network—When energized (maintained), selects thenetwork communications port A terminal block (TB4) and/ornetwork communications port B (TB5) as the source ofmotor control. Both network communications ports maybe used to operate the S611 from a Modbus (native),DeviceNet, or PROFIBUS network. When this terminal isenergized, Start commands from the start terminal block(TB3) are not recognized. Both comms ports may beused simultaneously and independently configured.www.comoso.com
