Automation System

E-MAK asphalt plants’ automation systems

E-MAK asphalt plants’ automation systems software and hardware projects are prepared especially according to clients’ demands, requirements, use conditions (geographical environment, climate, fuel to be used etc.) and manufactured to operate the asphalt plant economically and efficiently.

Hardware

  • Full automatic control via main PLC
  • BUS connection system between main PLC and field automatic control PLC systems
  • Special PLC to ensure work safety
  • Ergonomic, quick, easy, user friendly screens
  • Secondary touch screen as operator panel 
  • A monitor shows all on/off states, malfunctions etc., second monitor shows all motors electrical current and temperature values
  • High quality, first class, heavy duty - minimum IP55 components are used for field automation
  • Control cabin is container type, insulated, has double glass windows, air-conditioned and with anti static flooring
  • Wide view from within the cabin

Software and Process Control

  • Process control recording and monitoring with SCADA software
  • Special programme for reports and graphic output
  • Cold silos feed flow speed is adjusted automatically according to mixture proportions and corresponding hot aggregate silo level measured via continuous level sensors (radar)
  • Required process parameters are evaluated, monitored and automatic controls are carried out accordingly.  Heat monitoring thermocouples and infrared heat sensors, material level radars, capacitive sensors, motorized level sensors and level switches, air-pressure and vacuum monitoring sensors and moisture sensors are used to control production processes.
  • E-MAK’s automation remote control system supports asphalt plants assembled throughout the world
