CHESTER Centurion 500, Operation Manual

Page: 13 / 46

Electrical System
Composition
The system consists of alternating current contactor (-K), red emergency button (-SI), green (-S2), pilot (-
HL), micro switch (-S3,-S4,-S5), shift switch, etc. the system has the protection of lose-voltage, and cutting off the
current when the cover is opened.
Operation
When you have finished your job on the lathe, close the entire protection instrument; return the red button to
the original position. Now you can push the green button, the pilot light will now come on (this shows that the
alternating contactor has been put through the main circuit) and the machine is now ready to use again.
Pushing the red emergency button will cause the alternating contactor to break down, this shut down the entire
machine. Another way of accomplishing this would be to open the doors for the machine, or lifting the guard up.
