  Electrical Industrial Installation Fault Simulator Trainer Model ELTR 015C The Fault Simulator Trainer consists of 12 mini modules can be mounted to implement the control circuits described in the Manual. Large number of different circuits can be designed by the instructors and students using the modules. The modules are aimed at implementation of industrial controls in order to create faults and simulate the fault conditions of more than 20 different types. The Manual describes the faults that can be simulated in the circuits. Practically, this is how the Simulator can be used:

• The instructor decides which circuit will be taken for experiment.
• By referring to the Manual. The required Modules are mounted on the rack and connected.
• The circuit is tested to make sure that there are no ‘real’ faults.
• The instructor simulates the desired fault by operating the related switch on the back of the proper module.
• The students analyze the failure and once found the cause, report their conclusion to the instructor.
• If the students have correctly identified the cause, the instructor can reset the switch to prove the correctness of the analysis.
