What is a local control panel?
Local control panels are generally there to control the machine or equipment locally or remotely and installed in the close proximity of the controlled device. These panels can house more devices than the operator push buttons.
What are the different types of control panels?
There are three basic types of control panels.
- Flat Control Panels.
- Breakfront Control Panels.
- Console type Control Panels.
What is a local control unit?
Local Control Unit (LCU), Wired. The LCU AL-4189 – Local Control Unit is a hand-held control box specifically designed and built to be used in conjunction with ORBIT/FR controllers and PCU’s. It provides the attendant (operator, serviceman etc.) with a high degree of flexibility in operating the system elements.
How does a control panel work?
In its simplest terms, an electrical control panel is a combination of electrical devices which use electrical power to control the various mechanical functions of industrial equipment or machinery. An electrical control panel includes two main categories: panel structure and electrical components.
What are different parts of control panel?
These components include:
- Main circuit breaker. This is like the disconnect of the main electrical panel leading into a home or office.
- Surge arresters.
- Transformers.
- Terminal blocks.
- Programmable Logic Controller (PLC).
- Relays and contactors.
- Network switches.
- Human Machine Interface (HMI).
How many categories are in the control panel?
By default, the Control Panel is displayed in Category view, which is separated into eight categories, ranging from System and Security to Ease of Access. To open a window with the Control Panel options for any one of these categories, simply click the category’s hyperlink.
What is MCC and MCP?
MCC – Motor Control Centre. MCP – Motor Control Power. MCP- Manual call point. MCB- Miniature Circuit Breaker.
What is MCC and PLC?
MCC : Motor Control Center or Substation where motor will be powered. PLC/DCS : Control System, where Motor can be controlled as per logic (Auto) or as per operator action (Manual). LCP : Local Control Panel which is installed in the field, near motor in which start, stop push buttons are available.
What is control panel box?
An electrical control panel is an enclosure, typically a metal box or plastic moulding which contains important electrical components that control and monitor a number of mechanical processes. Operators will interact with the controls of the panel to operate and control the plant and process.
Is standard for control panel?
Various standards have to be observed for the construction of control panels for machinery. IEC 60204-1 is the relevant standard, but it is the manufacturer’s responsibility to ensure the best possible electrical safety of the control panel.
What is a local control station?
Local control station seems to imply some panel with control push buttons and indicating lamps or a HMI touchscreen or even a desktop pc running SCADA software in an industrial console that’s used to control the processes or equipments that are in the immediate vicinity.
A local control panel is normally located close to a piece of equipment or group of machines. A local control station could be a complete process in a group of processes. A typical example would be a large underground fridge plant in a deep level mine.
What is the difference between a control panel and control station?
A local control panel is normally located close to a piece of equipment or group of machines. No hard and fast definitions… But a “panel” usually implies indications. i.e. One caveat though, a “control station” can be an air conditioned room where the operators hang out when not out in the plant doing things.
What is a remote/local control selector switch?
A Remote/Local control selector switch can often be situated in proximity to the controlled plant [i.e. LOCAL to the equipment] and allow an operator to take control locally and avoid the need to interact or accept remote supervisory commands.
