38 Drive Technology and Motor Control > Training Packages > Circuits with Contacts Basic Principles of Circuits with Contacts TP 1211 The fundamentals of control technology Basic control circuits also have their place in modern automation technology, as simple automation tasks are still set up with low-cost contactor circuits. Realistic projects are executed using the equipment set and practical exercises. The design, function and areas of application of the components are explained along with their use. Selecting the correct switching elements and equipment is just as important as the correct use and adjustment of protective devices. The general operating principles are explained using examples and the basic knowledge of the control technology with contacts is explained comprehensively. Training content – Pushbuttons and switches – N/O and N/C contacts – Jog mode – Self-latching loop – Pushbutton lock – Multiple control points – Indicator lamps – Design and function of a contactor – Electronic time relays – Overcurrent trigger and motor protection switch – Equipment designations – Connecting and testing a three-phase socket – Main and control circuit – Protective interlocking – Reversing contactor circuit – Star-delta starting up – Reversing contactor circuit with automatic star-delta starting up Advantages – Extremely compact equipment – Flexible thanks to the use of industrial components – Easily expandable – Jumper plugs for connecting the boards improve clarity – Stable angled screw-in sockets for contacting – The optional mobile solution combines work, transport and storage requirements perfectly, thus reducing the amount of work required before and after lessons
