Elevator Door OperationSafety and PerformanceUpgrades
People judge the performance &safety of an elevator by how wellits doors workElevator doors can make a lastingimpression about your building.Doors that are noisy, unreliable,unattractive or operatinguncomfortably could reflect poorlyon perceived building safety – andmanagement. Under-performing orunreliable elevators hinder efficientbuilding operation, with probabledowntime and expense.What is the condition of your elevatordoors? Ask yourself:Are the doors noisy or erraticin operation?n Do they open or close too slowlyor too quickly?n n o they sometimes fail to open orDclose at all?Do they occasionally strike passengerswho are entering or exiting the elevator?n The average elevator door opens and closes more than 200,000 times a year.No wonder over 70% of all elevator trouble calls are related to the door operation.2Do constant shutdowns andmalfunctions disrupt buildingoperations?n If you answered ”yes” to any of thesequestions, you may need a KONEelevator door operation upgrade.
The affordable way toenhance elevator operationDoors that operate improperly orerratically degrade your entireelevator system. Upgrading theircomponents is a cost-effective way todramatically improve elevator serviceand restore passenger confidence.The immediate benefits you mayreceive from an upgrade include:n ubstantially reduced noiseSand vibration.n Improved elevator efficiencyand performance.nE nhanced passenger satisfaction andcomfort.n ecreased elevator downtime andDbuilding disruption.nReduced operating expenses.n Compliancewith code and ADAstandards regarding door operation.n Enhancedsafety and reduced liabilityexposure.KONE offers door operation upgradepackages for every elevator. Theinstallation of an upgrade will bescheduled to best suit your needs.The components of each solution areoutlined on the following pages. Everycomponent is designed and engineeredto stringent KONE standards. Eachone is also manufactured from thefinest materials using the latesttechnology. You get the best –without compromise. That’s ourcommitment to you.KONE offers four door operatorsystem upgrades to ensure anefficient and reliable door operation.3
Solution 1:KONE ReNova KONE ReNova customized highperformance door modernizationsolutions deliver precision you canfeel. The mechanical coupling is solid,allowing smooth linear action of thecar doors and quiet operation. Theaction is swift and silent, consistent ateach stop regardless of differing doorweights and air pressure. Break theV3F inverter drive isintegrated with doorcontrol electronics.The system features a synchronousPMSM motor, excitation bypermanent magnets (no brushes).The drive system and trackallow for true “linear” motion.Elevator doors retractthe instant the infraredbeam light curtain isbroken, dramaticallyreducing the chanceof door contact withpassengers.KONE ReNova solutionsfeature patented KONE AMDtechnology. The substantialtrack design and resilient rollersare designed for long life.Clutch offers a solid couplingand quiet operation.4curtain of light and the doors willautomatically re-open.It’s a function of KONE’s closed-loopcontrol and patented AMD doortechnology. The performance profileis set according to your specificneeds. Then, operating conditions aremonitored and digitally encodedfeedback allows the system to learnabout your building. A PermanentMagnet Synchronous Motor (PMSM)and the Variable Voltage VariableFrequency (V3F) drive use thisinformation to deliver enhancedperformance every time.
Solution 2:G2M Door OperatorThe G2M Door Operator Upgradeeasily adapts to existing GAL dooroperator systems. The G2M dooroperator was designed to solve theproblems of outdated GAL doorsystems by reducing maintenance/operating costs and providingsuperior door operation withoutcomplete replacement. KONE’s G2MDoor Operator Upgrade featuresexceptionally smooth acceleration/deceleration soft-start circuitry. Thissolid-state control provides uniformdoor speed transitions.Another speed-regulation featureautomatically compensates fordifferences in door weights, producingconsistent operation from floor tofloor. Any speed adjustments requiredAn internal solid-state timer will removepower to protect the motor fromoverheating, if the doors don’t fullyopen or close within a preset timeAll speed adjustments are performedquickly on the car top, with theguidance of LED indicatorsare quickly and easily completed fromthe car top, with the guidance of LEDindicators. Sealed bearings and a cooloperating DC permanent magnet motorextend the life of your door operatorand reduce maintenance time. Thesefeatures significantly reduce shutdownsto enhance passenger safety, comfortand convenience.Drive linkage is reused, savinginstallation time and moneyDC permanent-magnet motor– quiet, efficient and durableSealed pillow blocksrequire no maintenanceQuiet belt-drivensystemOur flush-mountedinfrared electronicsensing devicereopens doorswhen people orobjects disrupt theinfrared plane5
Solution 3:MAC Door Operation Upgrades The MAC door operator is apermanent-magnet solid-state andclosed-loop operator which provideshigh-performance door operationfeatures for all types of applications:n Measures velocity feedback of the motorn Measures position feedback of the doorsnMicroprocessor control systemn Adjusts to various conditions, includingdoor weights and wind resistancen eets consultant closed-loopMspecificationGate SwitchThe purpose of the gate switch isto electrically lock the car doors.The elevator will not move untilthis switch is closed.Door RestrictorThe electronic door restrictor isdesigned to prevent elevatordoors from being forced openoutside a safe landing zone.Door Sensing Device –Infrared Light CurtainThe KONE infrared door detectingdevice increases passengersatisfaction and comfort whiledecreasing door-related callbacksand downtime. Forty-seveninvisible infrared beams detectvirtually any obstruction beforethe doors touch passengers ortheir property.Door LinkagePrecise control over door movementrequires that the linkage betweenthe doors and the door operatortransmit movement to the doorsefficiently, quietly and reliably.MAC door linkages are heavyduty use with maintenance-freesealed bearings.Door ClutchThe MAC door clutches aredesigned to provide positive,quiet engagement with thehoistway doors while maintainingclose tolerance clearances whilethe car is in motion.6
Solution 4:Hoistway DoorOperationUpgradesFasciaThe flat reinforced steel plate isinstalled vertically inside the hoistway,above the hoistway door hanger headerto the sill of the landing above, toprevent pinch points and ledges.Hoistway Door Reel ClosureThe reel closure ensures that thehoistway doors close tightly. It musthave adequate spring tension to pullthe hoistway door shut and actuatethe door interlock mechanism.Hoistway Door InterlockThe hoistway door interlockmechanically locks the door to preventit from being opened unless the car ispresent and completes an electricalcircuit to allow the elevator to move.UL Fire-rated Door PanelsThe fire-rated door panels aredesigned to resist standard fire testsand are labeled for identification.Hoistway Door DriveThe hoistway door drive works inconcert with the car door clutch totransmit the motion of the car doorsto the hoistway doors. The door drivesystem provides precise door controland quiet operation, while maintainingclose tolerances with the moving car.Hoistway Door GibsBoth the car and hoistway doors areguided at the sill with a device designedto allow freedom of door movementwhile providing secure positioning.Hoistway SillThe hoistway sill is the bottomhorizontal plate of the landing entrancewhich provides foundation and footingfor the elevator entrance frame.7
