KUKA KR C4 Midsize Fault Diagnosis

Maintenance cycle and inspection

The maintenance work of KR C4 midsize should be carried out on a periodic basis. At least annually, check the relay output of SIB and expand SIB, and clean the external fan protective grille. At least every 2 years, clean the heat exchanger, internal fan, KPP and KSP radiators, and low-voltage power radiator according to the degree of pollution. Replace the motherboard battery, control the PC fan, external fan, and internal fan every 5 years. The battery replacement cycle depends on the battery monitoring indication, and the pressure relief plug filter needs to be replaced when it changes color. After maintenance is completed, a visual inspection should be conducted to confirm that fuses, contactors, plugs, and boards are securely installed, cables are undamaged, PE equipotential connections are reliable, and system components are not worn or damaged. When cleaning the control cabinet, the power must be turned off and wait for 5 minutes. Use solvent-free, water-soluble, non flammable, and non corrosive cleaning agents. Do not use compressed air, spray water, or allow cleaning agents to enter electrical components.
