What are the most important electrical control system maintenance tasks?

Setting up monitoring of system under operation. Establish control mechanism. Record anomalies. Resolve system errors. Keep track of recurring incidents.

The most powerful tool are tightness and cleaning. When you are in cement manufacturing you have to monitor two things in control wiring which are mentioned above.

-Always inspect, monitor and test when your working in Industrial area where big marchines are working with controls.. -Your Schametic diagram reading is always important when dealing with controls

From my experience we have to do a visual inspection to ascertain how our harness is ,is it away from rubbing that may cause grounding,are relays properly secured,are battery terminals tight and firm all these aspects should be taken into consideration when it comes to machine maintenance.

Una de las actividades mas sencillas e importante es la limpieza de aisladores eléctricos, puesto que mi experiencia indica que las grandes fallas fueron ocasionadas por la perdida de aislación en estos elementos. De la ejecución de una buena limpieza pueden también detectarse anomalías como fisuras o pérdidas de torque en elementos de fijaciones mecánicas, las que también conllevan a fallas con altos tiempos de detención de los equipos

Cleaning is importantin proper operation of equipment longevity and reliability. making sure filters are clean and moving parts cleaned and lubricated according manfactured specs.

The accumulation of dust and debris can cause overheating and other issues. Regularly cleaning system components like panels and terminals is crucial.

In certain functions like Servo valve operation.oil to be maintained very clean and the mirco filter in the value to be cleaned periodically.

Testing and calibrating can be an important point. Systems can drift and become inaccurate over time. If the component is defective and has to be replaced, all data will be different and have to be adjusted.

Conduct periodic tests to ensure all system components are functioning as expected. This may include testing relays, circuit breakers, and other control devices.

Testing also supplements good cleaning and lubrication practices. By physically operating components, whether manually or automatically as part of the testing procedures, it’s good to “exercise” equipment to simulate its normal operating condition.

yes power supplies can drift, motor bearing can wear out. checking power supply voltages and adjusting them to correct specs. Taking thermal readings can also prevent a major problem if good notes are taking .

Shall have the time and when the system shall be calibrated and tested to ensure that the system work sufficiently and progress it's function.

- Inspection strategies is crucial for effective run time of equipment/components -Follow prevenetative maintenance strategies to reduce the risk of breakdowns. -Proper drawing reading skill can reduce faultfinding time and ensure efficient methods to get equipment running again.

Very important step, making sure repairs are done correctly , hoping to correct the reason how it got damaged in the 1st place.

Shall have a good response and fast reaction to treat with the sudden faults and can fix it at the shortest time as possible to save the production process

This step needs to be done cautiously to make sure a components still operate correctly. Some occasions while updating or upgrading some components may not be compatible or not operate correctly. Always read upgrade directions carefully before attemting them.

Older ac drives power supplies fail as things like capacitors deteriorate Understanding conditions is critical to real plant maintenance

Collaboration and sharing of information with your team(s) responsible and accountable for operations of your systems. Making use of as an example time stamped database reporting repository to be accessible to authorized members of your company and management.

Thermal scanning will show what you cant see. Loose connections on breakers, relays and contactors. Lugs or ferrols that have to be crimped again. Wires that are being overloaded. Circuit breakers and contactors that are getting warm because of warm contacts.

Control eng. Shall be a well known about the machine which wanna control and know it's history and also the function of the system which wanna controled.

Above all of the already mentioned important tips, don't for SAFETY above all else. Nothing gets done if safety isn't followed, and someone gets hurt or killed.
