The Trainer 1102 model – KfZ focused on experiments for training in car electronics.

School exercises derived from model 1101 including the Electronic I and Electronic II study guides added experiments 11.58 to 11.86.  An LN500 power supply was also included.

Topics of discussion and exploration included:

  • Definition of important units of measurement and conversions
  • The relay in the vehicle
  • Zener diode voltage regulation with z-diode flashing circuit with switchable frequency
  • The thyristor circuits in the vehicle
  • Switch-on and switch-off delay
  • Brake lining wear indicator
  • Induction
  • Inductive sensors e.g. emergency ignition angle
  • Closing angle control
  • Temperature sensors in vehicles
  • NTC resistor
  • Preheating circuit
  • Tachometer
  • Pump relay
  • Alarm systems

This model was later refreshed and a new manual designed for its release as the LectronRWO expansion model 1005.
