1. The electrical control cabinet installed with PLC should have a clean and dry environment. Moisture-absorbing dry materials should be placed inside, and the splashing of coolant and oil mist should be prevented.
2. Regardless of the system working or shutdown, the electrical cabinet door should always be closed to keep the electrical parts well sealed.
3. Keep the ventilation of the fan of the electrical cabinet (if installed) well, avoid the area where coolant and oil mist splash the vent, and keep the air inlet clean and dry.
4. Regularly inspect, clean or replace the fan filter and dust filter according to the specified requirements.
5. Regularly clean the dust inside the electrical cabinet and electrical components, and keep the electrical components in a good working environment and working condition.
6. The inlet and outlet of cables and wires should be kept sealed to prevent the intrusion of debris and dust.
7. Regularly inspect and replace the vulnerable parts of electrical appliances to ensure that all electrical components are within the specified service life.
8. For the contactor of on-off high-power components, the contact status of the contact should be checked regularly, and the contact surface should be cleaned to prevent oxidation.
9. Regularly inspect the detection components and switches installed on the equipment, and clean the iron filings, dust and other dirt on them at any time to ensure reliable action.
10. Check the power supply. The quality of the power supply directly affects the reliability of the PLC, and it is also a component with a high failure rate, check whether the voltage meets the rated range of 85%-110% and check whether the voltage fluctuation is frequent.
11. Check the operating environment.
12. Check whether the battery of the PLC's program memory needs to be replaced.
