InstallationS811+ Soft Starter MN03900001E—November 2012 178–Ext Trip–Control Input 24 Vdc only (maintained) The S811+unit may be tripped by an external device. Removal of the24 Vdc signal (maintained) will initiate a Fault Trip action.Functionality of this feature will remove power from themotor with no soft stop ramp or pump stop ramp, if enabled.9–Ext Warning–Control Input 24 Vdc only (maintained) TheS811+ unit may receive a Warning signal from an externaldevice. Removal of the 24 Vdc signal (maintained) will initiatea Fault Warning action. Functionality of this feature will reporta Fault Warning and allow motor control by control inputsignals.10–Disable OL on Strt–Control Input 24 Vdc only (maintained)Applying 24 Vdc to this input prior to the soft starter receivinga START command will disable the overload functionality ofthe soft starter during the start ramp profile only. When themotor reaches synchronous speed and the S811+ closes theinternal bypass contactors, overload protection will beenabled.11–Analog–Terminal #4 of the terminal control block may beconfigured for analog input. Analog input ranges are 0.0–20.0ma DC and 4.0–20 ma DC. Range scaling is 0–100% withprogrammable high and low Fault Trip or Fault Warningalarms. The analog input trip threshold is user adjustable andmay be set to Fault Trip, Fault Warning, or Disabled.The S811+ Soft Starter contains two (2) auxiliary contacts toindicate status. Both relays accept user defined attributes.Relay Configuration OptionsNote: The Custom Fault/Warning option will accept anycombination of user selected fault trip or fault warningcodes. The relay will change state when any one ofthe selected codes is present. If multiple codes occursimultaneously, the fault trips will have priority overfault warnings.Note: Custom Fault/Warning relay operation is dependenton fault protection operating parameters. If a faultparameter is entered into the Custom Fault Warningoption, but the fault parameter is disabled, theCustom Fault/Warning relay will not react to the faultcondition.Option Relay Config Options Notes0 No Function OFF1 Fault Relay changes state when any Fault occurs2 Fault NOT3 Bypassed Relay changes state when internal bypass contactors close4 Bypassed NOT5 Motor Energized Relay changes state during Start ramp, Top of Ramp (Run), SoftStop, or Pump stop.6 Motor Energized NOT7 Warning Relay changes state when any Fault Warning occurs.8 Warning NOT9 Custom Flt/Warn Relay changes state when any selected fault/warning code isdetected, up to a maximum of three (3).
