8 OPERATION AND INSTALLATION INSTRUCTIONS MN280075EN July 2018Form 6 microprocessor-based rack-mount recloser controlControl featuresThe Form 6 recloser control offers numerous standardfeatures and accessories that allow the user the utmostflexibility applying the recloser control.Control securityThe Form 6 recloser control has multiple customer-programmable security codes to limit control programmingand viewing function access to authorized personnel. Thefront panel Human-Machine Interface (HMI) includes auser-selected security code to access the settings. Plus, theProView interface software has it’s own security levels formultiple-user access.Refer to Service Information S280-70-4 (ProView 4.X.X) orS280-70-21 (ProView 5.X.X) Form 6 Control ProgrammingGuide for additional information.Protection profilesFour protection profiles capable of fully specifying controloperation are standard in the control. Each protection profileincludes the following as a minimum:●● Overcurrent Protection●● Over/Undervoltage Protection●● Over/Underfrequency Protection●● Directional Protection●● Hot Line Tag Functionality●● Sync Check●● Sensitive Earth Fault Protection●● Sequence Coordination●● Operation SettingsTime current curvesTime-current curves are available for numerous functions,including fast and delayed operations for phase, ground, andnegative sequence protection. Each time-current is selectedfrom a defined fifty curves which can be further customizedby the user. The time-current curves are also selected froma graphical TCC Editor II to visualize any modifications priorto configuring the control.The time-current curves include the following modificationsfor phase, ground, and negative sequence protection:●● Time Multiplier with a range of 0.1 to 25 in .1 increments.●● Time Adder with a range of 0 to 30 seconds in .01second increments.●● Minimum Response Time with a range of 0.1 to 1seconds in .001 second increments.●● High Current Trip multiplier with a range of 1 to 32multipliers in increments of 0.1.●● High Current Trip Time Delay with a range of 0.01 to .150seconds in .001 second increments.●● Time Dial Reset co-efficient with a range of .1 to 30seconds in 1 second increments.Sequence coordinationSequence Coordination eliminates nuisance tripping throughtrip coordination. It allows the control to step throughselected operations in the operating sequence withouttripping. The number of Sequence Coordination advancesis programmable from one to three operations to providetrip coordination with a downline recloser. This feature isindependently selectable for each protection profile.Cold load pickupThe control includes a Cold Load Pickup feature to preventthe control from tripping while energizing non-fault systemloads. This feature has independently programmableminimum trip value time-current curve, reclose interval,and number of independent operations to lockout foreach protection profile. Cold Load Pickup also includesTCC Multipliers, TCC Adders, Minimum Response Time,Time Dial Reset, and High Current Lockout. Also, directvalues, not multiples of minimum trip, are provided for highcurrent lockout.Fast trips disabledThe control includes a Fast Trips Disabled feature to modifyprotection, so that all trip operations use the programmedTCC2. This feature is independently selectable for eachprotection profile. All trip operations will time on TCC2.Typically, TCC1 is fast and TCC2 is delayed. So, as anexample, the control will change it’s sequence from 2 fastand 2 delayed operations to 2 operations on TCC2 whenFast Trips Disabled is active.High current lockoutThe High Current Lockout feature will automatically lockoutthe control on the selected operation when currentexceeds a programmable level. The active trip numbers forthe lockout is selectable for phase, ground, and negativesequence. This feature is independently selectable for eachprotection profile.Sensitive ground/earth fault operationThe control has a Sensitive Ground/Earth Fault Trip featurethat provides tripping of the recloser after a programmable,definite time for ground currents below normal groundminimum trip levels. The feature has programmableoperations to lockout and reclose intervals independent ofthe ground settings. This feature is independently selectablefor each protection profile.
