PLC Process Trainer

Teaching Objectives of PLC Process Trainer

• To study automated control system associated to the hydraulic facilities (pump speed driving, level measurement, vessel draining, vessel stirring).
• Identification of the sensors, actuators, process to control, signals processing.
• Writing of a GRAFCET program.
• Permits more other to study a control loop with the introduction of an analogical measurement and an analogical action.
• To calibrate an analogical sensor and to study its linearity.
• PID single variable control loop (pH).
• Measurement of the input/output of the controller.
• Identification of the components (controller, actuator, sensor, process).
• Definition of the variables.
• Set point.
• Measure.
• gap variable.
• Adjusting size.
• Controlled size.
• Disruptive size.
• Algorithm Control (ON/OFF, PID).

Technical specifications

• The system is made up of a mixing stirred vessel feed by two other vessels. Each vessel is equipped with an electric draining valve, a manual draining valve and a low level probe. The mixing stirred vessel is equipped with an additional high level probe.
• This table top bench is made up of a stainless steel frame mounted on 4 feet with a PVC panel.
• 3 vessels
• 3 solenoid valves
• 4 level detectors
• A stirrer (motor and propeller)
• A control cabinet including :
• 1 section switch with lock
• 1 emergency stop button
• 1 rearmament button, 1 ON light , 1 start button and 1 cycle stop, 4 switches, the PLC wiring terminals
• The control and the stirrer safety device
• 1 transformer 24V, relay, solenoid valve, 1 contactor,1 DC power supply 24V for the PLC.
• It is made up of the same components with the bellow additional components:
• A pH control loop managed by the PID function of thePLC. It is made up of :
