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
Circuit symbol
bonded onto carrier
Component value
easily identifiable
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

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.

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
