The wires in this diagram have a letter designation
of color and a designation of the number of the circuit element to which
this wire is connected. Through the fraction indicates
the contact number of the block. The symbol "S28" or
"SB" means that the wire is connected to the circuit element
numbered 28 or marked with the letter B through a dot
