Causes and Maintenance Strategies for Controller Failures

2025-11-07 09:27:01

During operation, controllers may experience various types of malfunctions. The main causes include overload, poor grounding, oxidation of relay contacts, and external environmental influences. Overload can damage internal components of the controller, while poor grounding may affect signal transmission and power stability, thereby reducing the device’s response speed and reliability. Oxidation of relay contacts directly impacts switching performance, leading to control signal transmission failure.

To address these issues, regular maintenance is particularly important. Monitoring load current, checking grounding connections, and cleaning or replacing relay contacts can help ensure that the controller operates in optimal condition. In addition, conducting comprehensive periodic inspections can help detect potential problems in advance, effectively extending the equipment’s service life and improving overall safety and reliability.
