NOTE :
1. This is the control circuit of the Assy., ECU P.W.Board of INA-N333R S/INA-N333RRS
.
2. This ECU has three types of connectors CN1 -CN3 for connection of
input/output to/from an external unit, and is provided on the P.W.Board.
3. For the convenience of drawing the circuit diagram, the signals are
expressed by the symbols shown in the notes, but the signals having
the same nsme are connected.
(Example)
Signal
Pin No. of Connector
Symbol No. of Connector
4. AS to the electric signal, the element enclosed by a broken line indicates
a compsite elements, based on JIS C 0301.
5. In a capacitor, the element symbol is as shown below.
6. For the convenience of drawing the circuit diagram, the following rough
sketch is used. The meaning is as shown below.
In the above description, a thick line is called a BUS line and the BUS line
having the same name are connected.
7. In the circuit diagram, elements indicated by a broken line are not
assembled, but a circuit is provided on the P.W.Board for the change in
specifications.
