4.1 NOTES ON THE MAIN POWER SWITCH (SW1).........................................................4-1
4.1.1 PUSH SWITCH ...................................................................................................4-1
Characteristics of the Push Switch (Main Power Switch (SW1))............................4-1
The push switch in this machine uses DC (direct current). Therefore, if the AC
power cord is connected to an electrical outlet, power is supplied to the controller
board (PCB24), the operation unit and other modules even when the main power is
turned OFF. When replacing the controller board (PCB24) and the operation unit in
this state, not only these boards, but other electrical components will be damaged.4-1
When you disconnect the power cord from the AC wall outlet, there is still residual
charge inside the machine for a while. Therefore, if you remove boards in this state,
it can cause a blown fuse or memory failure. .........................................................4-1
In order to remove the residual charge, push the main power switch (SW1) after you
disconnect the AC power cord. At that time, the power ON flag inside the machine is
set. Therefore, after you finish work on the machine and reconnect the power cord
to the AC, even if you do not press the main power switch (SW1), the machine will
start automatically and the moving parts will begin to move. When working on
moving parts, be careful that fingers or clothes do not get caught.........................4-1
