Referring to your AJS1/M20.1.26, we do not think the type of diagram represented by your LeC.2194 is so clear and easy to follow as the type of diagram which we send herewith. In this diagram the identity of the units is easily seen, without at the same time making the various circuits any more difficult, and in our opinion, a good deal easier to follow. We are of the opinion that any electrical diagram in a case like this, of a system of only a few circuits, there is no need for both a practical wiring diagram and a technical winding diagram, but that it is much better to give one diagram which is half way between the two, and shows all that is required, and we propose that we insert a diagram of this type in the Instruction Book, in explanation of the sequence silence starter, when we adopt this. This will be in addition to the present two diagrams of the whole system in which details of the sequence silent starter can be more or less omitted. Any diagram showing the connections of various units to one another should invariably clearly show the terminals of such units so that the compass of each particular unit is clearly indicated, and the diagram should be so arranged that the number of crossings be | ||
