MRB3714E1 Compressor Troubleshooting Trainer Refrigeration Trainer Vocational Training Equipment
1. Introduction
1.1 Overview
This system is developed for the field of compressor troubleshooting. It will enhance the understanding of logical troubleshooting procedures and can observe and test various faults under the system. Faults can be easily activated and the system can be immediately restored to the normal allowable state. In addition, faults can be hidden for testing.
Each fault has an LED indicator. A fault activation pin is also provided to control the fault. After the fault is activated, it can be detected using a multimeter.
1.2 Features
(1) Circuit block diagram display
The electronic circuit block diagram is swiped onto the display panel. The highly visible circuit diagram can enhance your understanding of the system circuit and is essential for developing troubleshooting skills.
(2) LED fault display light
Each fault has an LED display light that displays when the fault is activated. This can help you visualize the current fault.
(3) Easy fault activation
A switch is used to activate each fault. Faults may appear one at a time or in various combinations. There is no limit to the number of faults that can be activated at one time. You can even activate them all if you want.
(4) Interactive fault learning
After activating a fault, you will receive immediate feedback and the corresponding symptoms are obvious. This allows the corresponding symptoms of each fault type to be observed and learned, which greatly speeds up the process of gaining valuable troubleshooting experience when seeing the system fail due to various problem products.
(5) Test mode
The LED fault indication display can be deactivated so that the fault can be activated but the display is turned off. In this mode, you can introduce a series of faults without the other person knowing which faults are being used. You will then be able to ask the other person to use the test points to determine where the fault is.
(6) Fault reminder
This is very helpful for the instructor in case the other person forgets which fault was activated. When the system is in hidden fault, just press the LED control button and the last activated fault will be displayed. When the button is released, the fault mode will return to hidden.
(7) Return to normal mode
Press the reset button and the system will automatically return to normal.
