3.2.2 Maintenance scheduleGeneralThe robot, consisting of robot and controller cabinet, must be maintained regularlyto ensure its function. The maintenance activities and their respective intervals arespecified in the table below.Non-predictable situations also give rise to inspections of the robot. Any damagesmust be attended to immediately!The inspection intervals do not specify the life of each component.Activities and intervals, standard equipmentThe sections referred to in the table can be found in the different chapters for everymaintenance activity.The table below specifies the required maintenance activities and intervals:Detailed in section:IntervalEquipmentMaintenanceactivityCheck for abnormal wearor contaminationRegularly iFor Clean Room robots:DailyRobotInspectionInspecting dampers onpage 99Regularly iDamper, axes 1, 2and 3InspectionInspecting the robotcabling on page 95Regularly iCable harnessesInspectionInspecting timing belts onpage 10136 mthsiiTiming beltsInspectionInspecting plastic coverson page 105Regularly iPlastic coversInspectionInspecting mechanicalstops on page 96Regularly iMechanical stoppinsInspectionReplacing the batterypack on page 10936 months or battery lowalert iiiBattery pack,measurementsystem of typeRMU101 orRMU102 (3-polebattery contact)ReplacementReplacing the batterypack on page 109Battery low alert ivBattery pack,measurementsystem with 2-pole battery con-tact, e.g.DSQC633AReplacementCleaning the IRB 120 onpage 112Regularly iComplete robotCleaningi "Regularly" implies that the activity is to be performed regularly, but the actual interval may not bespecified by the robot manufacturer. The interval depends on the operation cycle of the robot, itsworking environment and movement pattern. Generally, the more contaminated environment, theshorter intervals. The more demanding movement pattern (sharper bending cable harness), theshorter intervals.ii Service inspection including dismounting of robot parts shall always be done outside the cleanroom area.Continues on next pageProduct manual - IRB 120 933HAC035728-001 Revision: N© Copyright 2009-2017 ABB.
