Welcome guys, now I will open up a new topic which is Faroals. This is not directly related to auto retroins but also most of the time showing the Faroals and how you have to make Faroals. Faroals basically, let's see the next picture. For example here you can see these are wires coming from the external source and these are connected to the terminal block. So this white color, printed, these small tubes are called Faroals. So here normally in the panel you will see the terminal block and these Faroals are showing only the one side information, the probability showing the cross, the other information. If the Faroals consist of information of local as well as the remote side or you can see the word source and destination both addresses are mentioned on the Faroals and it's called cross faroals. So it's always good to have a cross faroals which is really useful for troubleshooting. Another thing is at the end of the sheet you will find a trombination schedule or trombinial assignment. In this trombinial schedule or trombinial assignment you will find the trombinial mention and it's the source from which wire is connected to and from the trombinial is shown very clearly. So this is how the Faroals are and you should know about them.
