LC2030 Workstation

Description

The LC2030 workstation was designed for training in control engineering. It offers a wide range of training options, from simple control tasks to different closed loop control systems

Three float switches and a pressure sensor detect the level. The level can be changed using three pumps. Switches and buttons on the control panel enable extended operation. Signal LEDs enable the display of errors and process statuses.

All analog signals with 2..10V and all binary signals with 24V are available on the control panel of the system via 4 mm safety laboratory sockets. The system can be connected to the PC via I/O boards. The optional LC2030 Training serves as a complete process control system for the system with visualization.  The training system can also be operated with all standard control and regulation units (PLC, industrial controller, etc.).

Details and Options

The training system in this configuration allows various control engineering experiments to be carried out and consists of the following components:

• Adjustable pump for level control and/or flow control 
  The adjustable pump is located in the tank drain and is coupled with a level sensor. This enables level control and flow control. In conjunction with the controllable valve, flow control and level control can be coupled together. The pump is controlled via a frequency converter, which is supplied with 0 - 10 V via safety laboratory sockets.
• Pressure transmitter for level measurement/control 
  The pressure transducer supplies a 2 -10V signal to the laboratory sockets. In combination with the controllable pump or the controllable valve, the level can be continuously controlled.
• Flow sensor for controllable valve (optional)
  The 0 - 10V of the flow sensor are routed to safety laboratory sockets. The flow sensor measures the inflow downstream of the controllable valve. The adjustable valve can be used to implement flow control. This flow control in the inflow and a level control via the controllable pump in the outflow can be coupled together. The flow control then acts as a disturbance variable on the level control.
• Adjustable control valve for level/flow control (optional)
  The control valve controls the inflow of the tank and can be used to implement level control and flow control. Flow control and level control can be coupled with each other via a controllable valve and controllable pump. It is controlled with 0 - 10 V via safety laboratory sockets.
• Flow sensor for adjustable pump (optional) 
  This flow sensor measures the outflow via the controllable pump. The flow control in the outflow and the level control via the inflow can be coupled together. The flow control then acts as a disturbance variable on the level control.
  The analog output signal of the sensor (0 - 10 V) is routed to safety laboratory sockets.
• Pressure sensor for controllable pump in the drain pipe (optional) 
  The pressure control consists of a sensor, a manual valve and a pressure gauge for reading the pressure. The 2 - 10V of the sensor can be tapped on the laboratory sockets.
  The pressure (max. 0.4 bar) is generated via the adjustable pump.
• Heating element, Pt100 temperature sensor and additional circulation pump for temperature control (optional) 
  The heating rod enables the water to be heated. The heating rod is switched on/off via a 24V DC signal. The temperature sensor supplies the temperature as 0 - 10V to the laboratory sockets. A circulation pump ensures that the water is mixed more evenly. The circulation pump is permanently installed in the training system, while the heating rod and temperature sensor are attached to the top of the tank and can be removed if necessary.
• Cooler with 2 fans to speed up the cooling process (optional) 
  The cooling system consists of a water/air cooler and two fans and enables the cooling process of the water to be accelerated using temperature control. The fans are controlled via a 24 V DC signal.
  The cooling system is placed separately next to the training system and connected via the hoses supplied.
• Measuring cable set (optional) 
• I/O board for connecting the system to the PC (use of the LC2030 training)
