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?

Makes learning easier Saves preparation time It lasts and Lasts Versatility Support

Spring clips riveted on for strength

Components identifiable under

carrier

Strong soldered joints

Simple repairs can be made in-house

Component value easily identifiableCircuit symbol

bonded onto carrier

Most up to date circuit symbols now

available

Custom made metal clips can be bent

many times.

Durable, robust plastic carriers are

long lasting and cost effective

Rust proof springs ensure good connection

Curriculum packs – most are free of charge

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
