Heater tank section:

• This section of the Mimic Panel should include sockets for the:
• Output signal from the Temperature Transmitter (TT1), located in the side of the Heater Tank to provide a measure of the temperature of the water inside the Tank (the outflow temperature)
• Output signal from the Temperature Transmitter (TT2) located in the return pipework to measure of the temperature of the water re-entering the Heater Tank from the Process Vessel (the inflow temperature)
• 2 mm socket and a potentiometer to provide control over the delivery of Pump 1 in the Heater Flow Loop of Process Control Training System experiment module
• Toggle switch to select whether the pump speed is controlled manually (Manual), or whether it is controlled using an external source (External)

Reservoir section:

• This section of the Mimic Panel should include:
• 2 mm socket and a potentiometer to provide control over the delivery of Pump 2 in the Process Flow Loop of Process Control Training System experiment module
• Toggle switch to select whether the pump speed is controlled manually (Manual), or whether it is controlled using an external source (External)

Low water level indicators:

• The bottom right-hand corner of the Control Module should include two LED indicators labelled as Heater Tank Low Level and Reservoir Tank Low Level

ADA section:

Control Software Features:

• To be used with control module for real-time control of Process Control Training System experiment module and data acquisition
• Software should combine controller design & implementation into one logical process
• This should reduce learning difficulties and help quickly to understand & create a working control system
• User can use the software icons and wire them together on screen, just as they would draw a control system on a piece of paper
• The icons should include important parts of controllers, signal generators, manually controlled signals & voltages and virtual instruments
• The software can be used to record important variables
• Plotting the results in a chart and exporting data for use in other programs
• Students can create one or more types of controller and simulate the theoretical responses
• The user guide should show users how to use the software and how to build and test common control systems, such as:
• Design and implementation of three-term controllers
• Design of controllers and filters
• Simulated signals: Signal generator (sinusoidal, saw tooth & square wave), with variable frequency, amplitude & offset and D.C. level (fully variable)
