This time we´ll have an overview of a test assembly I have made for, you can guess...test different programs and wirings.
The test assembly is build in a very simple way, as I wanted to cut cost and at the same time, build it with easy acess in case I wanted to make some changes to the design/wiring.
For now you can get an overview of how it works. In the future I will upload a look into the wiring it self (wiring diagram) and the progam that I used for this example.
The test consists on three different approaches:
- The first approach is to work with the auto mode ON. In this way, the output will be the result of what the PLC it programmed to do with the input signals that are received.
- The second approach it´s a simple test to see wether the signals are processed when the equipment is OFF (on the selector, still with power going through).
- The third approach is to work with the manual mode ON. In this case, the behaviour will depend on the wiring that you decided to make.
As you can see the construction is based on a chipboard (cheap and easy to get in friendy sizes to take in your vehicle).
It consists of a LOGO PLC (programable part) and it´s components such as relays, a power supply (12 V, to use with the proximity sensor), pushbuttons, selector buttons, signal lamps and a capacitive proximity sensor (detects any type of material).
A closer look to the individual parts:
