Control panels

General specifications

  • Types of manufactured control panels (CP) by industry application:
    • General industry monitoring panels;
    • Control panels for rolling-mill industry;
    • Control and monitor panels for mine winding plant trip;
    • Control panels for DC and AC electric furnaces.
  • CP represents a control system consisting of controllers, interface and display facilities located on the panel consoles and pedestals.
  • CP is designed for control and monitoring of technological equipment, see next figure.

                Human-computer interface

  • CP provides for control of both a separate installation and the whole production line.

General structure of CP

Design features

  • A modern control panel for equipment can be manufactured with and without an operator panel.
  • The control panel includes buttons and switches for technological equipment monitoring.
  • For assembly of operation control and indication elements we use the equipment by Schneider Electric, IEK and other companies.
  • The name plates of operation control elements are made on aluminum plates of anodized aluminum, and the symbols are engraved by laser marking – this ensures their resistance to external influences and durability.
  • Foremost, cases by Rittal are used for control panels.
  • The visible surface is made of polymer-composite materials, covered with semi-gloss smooth non-glare enamel resistant to abrasion and chipping.
  • The material of the panel is resistant to water, oils and diesel fuel. Products can be painted in respective colors.
  • Visible surfaces are easy to clean with common cleansing agents.
  • All documents that confirm environmental safety and fire resistance of the materials used for the manufacture, are available for review.

The CP consist of

  • switching and control elements;
  • a controller that provides control of operation modes by operator’s command;
  • monitoring and control unit (based on the Weintek operator panel or an industrial computer with a display) that collects and displays information about the main parameters state for electrical, mechanical and other systems (depending on the designation);
  • equipment of security system;
  • network interfaces:
    • Modbus;
    • ProfibusDP;
    • Ethernet,
    • CAN, etc.

Location

  • The CP may consist of several separate structural parts (sections), which can be spatially located in different places; sections can be connected between themselves both by radial and network communications;
  • The control panels fall under the following groups: central and local control panel:
    • The central panel is intended to display all parameters of the technological unit and general control thereof.
    • Local control panels are installed immediate close to the working mechanisms for their convenient control in manual mode.
  • The panels can be further broken down by the place of installation into attached and floor-mounted CPs.

Technical specifications

General provisions

  • By using the control panel, the user can monitor 10 attention-demanding individual objects at the same time. For each object, all indicators are available (in case if industrial PC is installed and display of tags from OPC servers is set), indicators can be assessed on a real time basis in a form of diagrams and graphs;
  • Through the control panel, providing for visual displays the system’s parameters in real time, it is possible to fulfill automation of technological processes (in metalworking, mines, etc.);
  • Display facility for incoming data and controllers are located on the panel, which ensures:
    • control and management of technological process, as well as data display;
    • process safety and automated control for the purposes of maintaining equipment parameters through warning indicators and alarm notifications;
    • automated and manual remote control of the process using the control panel, keyboard, programmable logic controller, switches or buttons;
    • recording and storing of technological parameters for the system, equipment and management actions by maintenance staff by means of the embedded capability of the Weintek operator panel or relevant applications on the industrial PC;
    • real-time data transfer and prompt communication between supervisors and engineering and management staff at all levels (subject to respective communication arrangements via network protocols).

Diagnostic tools

  • signal recorder;
  • the event log:
  • software for diagnostic panel and a laptop for graphical display of data from recorders and text visualization of logged data;
  • Internet access:
    • intended to enable equipment operation diagnostics by the experts of the manufacturer;
    • Access is provided by Internet via the diagnostics panel, using:
    – “3G” radio modem being an integral part of the diagnostic panel package;
    – Wired or Wi-Fi Internet provided by the Customer – in this case, the quality of communication (speed and uninterrupted operation) and the number of monitoring functions can significantly increase.
