ESSAI-DIAG is a model for producing faults at different points on a wiring frame. The wiring on frame represents the Star/Delta startup with double direction of rotation of an asynchronous machine. Only the control circuit is wired. Finding the faults is carried out only on the control circuit. The faults are selected by the instructor using the switches located under a rear flap of the model.
Educational objectives
• To learn and understand the wiring of motor startup
• To produce an industrial wiring diagram
• To simulate the most frequent faults on an industrial installation
• To take the measurements of the different electrical values
• To analyse and interpret the results
• To find the faults on a relay installation
Composition of the model
• 1 frame on casters (two with brakes) with dimensions H1800 x 800 x 700mm
• 1 Melamine shelf 750x400mm
• 1 wiring frame equipped with:
1 protection with two-pole fuse
1 relay 4 poles 24VAC
1 relay 4 poles timed 24VAC
4 contactors 4 poles
1 thermal relay
1 PVC surface including:
1 emergency stop button
1 On/Off button with indicator light
2 On pushbuttons
1 Off pushbutton
3 white indicator lights
3 green indicator lights
1 red indicator light
1 emergency stop for the instructor.
All the connectors of the indicator lights and pushbuttons are brought to
industrial terminals flush with the surface. Thus students can very easily,
using the probes, read the voltage or check if the circuit is cut.
• 1 unit closed with flap containing:
10 switches for creating faults
1 main switch
1 RC thermal-magnetic circuit-breaker 30mA-16A
1 key operated switch with indicator light for applying power to the wiring frame
