Lesson in electronics and PLC

Here the students have to make a contactor work if they push a button. It shall release if the red "emergency"-button is pushed or when the blue sensor is beeing influenced.

They have to couple the wirings and program the PLC. The programming is done whith a program on a PC and then transferred to the PLC. The PLC is the white thing in the middle.

The black contactor to the right works like a electric-controlled "pushbutton". An electronic magnet will affect a contact when energized and by that way for instance start an electrical motor.

The contactor vill switch on when the PLC is sendin a signal to it. This is done by the downloaded program in the PLC. If it doesent work as it should, the student start faultfinding. It could be a fault in the couplings or in the program.

Lesson in pneumatics

Here we can see a student working whith pneumatics. Whith help of compressed air they learn the basics in how to controll cylinders whith help from different valves. The walves can distribue compressed air in different direktions so the cylinders can move in and out.

Further into the school building

Now inside we can see an area ment for coffeedrinking or just talking. Above we can see the open learning-area where we have computers and studieplaces for students. In case of sparetime they can study by themselves or with help from jokerteachers, as we call them. They help them in maths, physics, electronics and so on.

By the way, my name is Jörg Örnberg. I´m a teacher in technical subjects such as mecatronics. In our school we here include mechanical things that moves and have an electronical touch, such as industrial robots, equipment which moves or transports products and is controlled by some kind of controller such as a PLC (Programmable Logical Controller).

I have been working in this school since Y 2000, before that i worked in Volvocars bodyshop controlling and serving a robot weldingline.

Inside entrance GTC

Now we are inside the entrance, in another schoolbuilding in the area. Photorestriction makes it impossible to take a photo from outside here.
