Description

Fault localisation in contactor circuits. Compact device with integrated fault simulation.

OBJECTIVES:

  • Function of contactor circuits
  • Fault localisation in contactor circuits

Compact device for systematic error detection in conventional contactor circuits. By masking different masks, only the measurement and connection points which are important for the circuit depicted on the mask are released

On the left side of the device is behind a lockable door the control panel for the instructor, which contains next to the protection devices, the mask selector switch also error switch.

Students should learn a systematic error search with the help of voltage- and continuity testers.

The error analysis is carried out in 4 steps

  • Description of the error
  • suppose cause
  • Error detection by measurement
  • Description Test method

 

LEARNING METHOD:

Student experiments following task description in the manual. The measurements are made with a voltage tester and continuity tester.

The fault analysis is conducted in 4 steps:

  • Description of the fault
  • Presumed cause
  • Fault determination by measurement
  • Description of the test method

TARGET GROUP:

Vocational training: Electrical engineering in trade and industry

Medium learning level, preliminary knowledge concerning the contactor circuits to be analysed is required.

The required knowledge can be acquired by the equipment
