FadalMaintenance ManualTroubleshootingSymptom Possible Reasons SolutionTool disk is not rotating whiletool selectingTool disc does notstop at locatingposition1. Proximity switch of toolcounting and positioning oftool disc is not sensed2. Proximity switch is out oforder3. Index mechanism motor isout of order4. Motor brake is out of order5. Reed switch of toolreturning (protruding ofcylinder) is not at theproper position1. Brake of index mechanismmotor is not working2. Distance between proximityswitch of tool counting &positioning of tool disc andinducing block is too long3. Proximity switch is out oforder1. Adjust the proximity switchto the proper position2. Change a new proximityswitch3. Repair the motor or changea new one4. Check the wiring or changeits parts5. Adjust it to the properposition1. Check if wiring of brake iscorrect or if its parts are outof order2. Adjust the distance betweenproximity switch andinducing block to be closer3. Change a new proximityswitchTool disc keepsRotatingFixing base of toolpot is deformed1. Distance between proximityswitch of tool counting &positioning of tool disc andinducing block is too long2. Proximity switch is out oforderTool disc rotates while toolpot is falling1. Adjust the distance betweenproximity switch andinducing block to be closer2. Change a new proximityswitchChange a new set of fixingbase, and adjust, then putspring inTool disc is stuckwhile rotating1. "C" snap ring is loose, orparts of tool pot fixing baseare falling apart2. Cylinder works while tooldisc is rotating, so tool pot isstuck at tool falling position1. Disassemble the scatteredfixing base and check eachpart if they are all workableof change a new set of fixingbase2. Check if the tool pot fixingbase is deformed.
