About Locktronics automotive Simplifying Electricity About Locktronics automotive

What is Locktronics? Locktronics is a range of products that simplifies the process of learning and teaching electricity and Electronics

Subject areas we focus on Science Electronics / Engineering Technology Automotive

The range consists of more than 200 items Baseboards Inductors System blocks Active subsystems Resistors Semiconductors Electromechanical Optoelectronic Capacitors Logic gates Curriculum packs Accessories

How does Locktronics work? Review curriculum Take a base board Follow instructions on worksheets Add components Learn through experimentation

Unique benefit of Locktronics As students construct the circuit they can see the circuit diagram. This helps students link theory to practice and simplifies the learning process.

Why choose Locktronics? Components identifiable under carrier Spring clips riveted on for strength Component value easily identifiable Circuit symbol bonded onto carrier Strong soldered joints Durable, robust plastic carriers are long lasting and cost effective Simple repairs can be made in-house Makes learning easier Saves preparation time It lasts and Lasts Versatility Support Most up to date circuit symbols now available Custom made metal clips can be bent many times. Rust proof springs ensure good connection

Curriculum packs – most are free of charge LK7325 - Electricity matters 11-14 LK7326 - Electricity matters 14-16 LK9392 - Introduction to digital electronics LK8392 - AC principles for automotive technicians LK8821 – An introduction to motors and generators LK8849 - Automotive sense and control LK9893 - CAN bus systems

Purchasing Locktronics Buy just one item, or a selection of items

Purchasing Locktronics Buy a ‘solution’ that includes PSU, current probe, storage trays etc.

Automotive – our goals To build the World’s best suite of training resources for auto electric courses To provide outstanding value for money and flexible purchasing options

Automotive companies that use Locktronics for training Some companies use direct in their own training establishments – some through third party training companies contracted to them.

Automotive in more detail

Methodology in automotive - starting Students are advised to study Electricity, Magnetism and Materials before going on to advanced courses. Students understand symbols, circuits, wiring, and theory Students must get involved in wiring circuits Students progress through ‘traditional’ subjects such as AC etc.

Methodology in automotive – sense and control Students understand: systems and ECUs Circuitry inside an ECU ECU wiring How software makes open and closed loop systems Circuit configurations Students work in pairs Students build circuits with 5 or 6 wires

Methodology in automotive – CAN bus Students: Wire up each node Test each node Students work in pairs or groups of 4 Each circuit contains up to 14 wires

Methodology in automotive – CAN bus Students wire up the whole system and use the admin /scan node to discover how the system works. This looks very difficult But students build it slowly and gain confidence in wiring

Key learning points about the CAN bus program Sensor ID D0 Side lights (A1) switch on 100 1 Side lights (A1) switch off Full beam (A2) on 101 Full beam (A2) off Left (A3) on 102 Left (A3) off Right (A4) 103 Right (A4) on Horn (A5) on 104 Horn (A5) off Wiper (A6) on 105 Wiper (A6) off Reverse (B1) on 106 Reverse (B1) off Brake (B2) on 107 Brake (B2) off Message structure and message transaction Students build up tables on all CAN data Students use diagnostic tools (Kvaser / Pico) for this
