Familiarisation with the most important components in a drinking water installation.
The automatic control is performed through a PLC, whose program manages the displays signaling vacant and full places, both at the entrance and at every floor, the lighting intensity at each floor, the opening and closing of the in and out barriers, regulated by the presence of at least one car detected by special sensors, and the smoke and fire detectors. The system represents a two storey parking garage where it is possible to realistically simulate all the sequences that a car driver has to perform when he wants to use an automated parking garage. The number of cars in the parking garage is displayed through LED, whose control is assigned to an electronic circuit separated from the PLC.

An elastic, vibration insulating installation of the machine avoids the transmission of harmful vibrations to the surroundings. The can be used to investigate the problems of foundations and vibration isolation using a practical example. This is installed on a foundation using springs and dampers. The foundation represents the surroundings and can be used to measure the effectiveness of the vibration isolation. An indispensible element of machine design is targeted reduction of vibrations. To do this, vibrations are generated and measured on a foundation. Springs are then used to try out different tunings and vibration absorbers are used to investigate absorption effects. This double vibration isolation, combined with the high fixed weight of the frame, guarantees vibration-free laboratory operation, even under unfavourable experimental conditions. Additional helical springs connect the foundation to the actual frame of the trainer.
