Maintenance & Technical Support

Routine sensor calibrations, software version control, panel inspections, and on-call troubleshooting agreements.

Technical Inspection of Automation Equipment and Panels

Regular inspection of hardware helps identify contact wear and prevent process shutdowns. Technicians check the state of panels, clean dust, and verify cooling fans. Regular technical inspection of control cabinets is part of supporting industrial automation at sites. Works are coordinated to prevent process disturbance. Technicians inspect circuit breakers, power supplies, and relays, looking for signs of heat discoloration. Preventative checks are scheduled during planned maintenance windows to avoid production stops.

  • Checking automation panel state at site.
  • Cleaning dust and dirt from cabinet panels.
  • Checking control cabinet exhaust fan function.

Diagnostics of Industrial Networks and Interfaces

Network diagnostics are aimed at detecting errors in communication buses and data links. Engineers check packet delivery between controllers and servers. This helps locate loose contacts or noise sources before communication drops. Detecting errors is critical for process control systems stability. Protocol analyzer tools are used to check signal quality on Modbus and Profibus industrial networks. High error counts trigger re-termination of shielding braid connections.

  • Diagnosing industrial data bus communication.
  • Checking for errors in controller network ports.
  • Locating electromagnetic noise sources on cables.

Inspection and Repair of Field Instrumentation

Checking field equipment includes visual inspection of sensors on technological lines. When faulty devices are found, repair or replacement is performed. Technicians check sensor mounts on piping. Technical inspection of field devices is coordinated with parameter displays in SCADA software. Transmitter displays are checked for error codes, and conduit entries are verified for moisture seals. Isolation valves are checked for smooth stroke travel.

  • Inspecting pressure and temperature field sensors.
  • Replacing faulty transmitters on process piping.
  • Checking physical mounting of field instruments.

Connection Checks and Fault Detection

Checking electrical connections includes verifying terminal screw tightness in panels. Loose terminals cause signal loss and control loop failures. Connection checks and fault detection are performed per maintenance checklists. If cable wear is found, reports are prepared, coordinating with personnel familiarization programs. We document all loose connections and insulation check values in the final inspection report. This check ensures that all connection points are secure.

  • Checking screw torque on terminal blocks.
  • Identifying worn or damaged cable sections.
  • Preparing defect lists for panel connections.
