Wiring of a tunnel access and ventilation system
This operational section, equipped with a containment cabinet, allows, with optional grilles, to study and install the wiring for a tunnel access and ventilation system equipped with a CO2 level control system simulated by a potentiometer. It includes a motor-driven fan responsible for air renewal.
The instructor demonstrates operation using the wired grille (GTUN1-ADC option).
The student then wires their own grille (KX-GTUN1 option) before installing it in the cabinet for testing.
Student safety is ensured by a cabinet door opening sensor.
This cuts off the power supply.
If necessary, a key-operated switch can be used to deactivate this safety feature.
Educational objectives achievable with the optional grid
• Observe and understand the operation of a ventilation control system
• Wire the different operating modes
• Test the wiring by inserting the grille and connecting it to the ventilation system
• Create different wiring diagrams
• Understand the role of each component
• Study the programming of a programmable logic controller with an analog signal
• Perform industrial maintenance operations
