| Aluminum windows and doors for faulty equipment , you should ask before and after failure after failure phenomenon and for unfamiliar aluminum windows and doors equipment , you should be familiar with the circuit schematic and structural characteristics , compliance with the appropriate rules to be fully familiar with each before removing the electrical components function , location, connection and relationship with other devices in the surrounding . Cleaning maintenance machines , boot before the various moving parts such as rails deputy campaign to clean lubricating oil must be empty to go after grinding . Changing the angle of the nose cutting blade must be observed whether the interference with the clamping device , the angle must be adjusted after the point of locking handle In determining the mechanical parts without failure , then the electrical aspects of the inspection . Inspection circuit fault detection equipment should use to find fault site confirmed that no bad fault, then targeted to view the relationship between the line and the operation of machinery in order to avoid false positives. Aluminum windows and doors equipment is not energized electrical equipment aluminum doors and windows judge buttons , contactors, thermal relay and the fuse is good or bad , and thus determine where the fault current test , listen to his voice , the measured parameters , determine fault last for maintenance. |
