3. Electric Circuit Control
3-1 Electric Wiring
You can find the electric control box by open the metal cover behind the lathe bed.
Connect the terminals “R”,“S” and “T” to power source. Note that the specification of
the electric wires must be above 8 sqr. mm of its cross section area. Power switch of
the machine and power source should be with fuse and the machine ought to be
grounded.
3-2 Electric Device
1) The electric pannel is equipped with cut-off device and solennoid contactor for
avoiding from overloaded breakdown of motor.
2 ) T u m b l e r R o t a t i o n S w i t c h c o n n e c t w i t h M i c r o S w i t c h .
3) Foot brake is connected with micro switch, braking prior to the manually starting.
Whenever you release the foot brake, you need to re-operate Spindle Control Lever
again to resume the operation of main spindle.
4) On top of the control box, there exist a “INTREMITENT” button for in-
termittent operation of the spindle.
3-3 Important Notes
**Check the rotating direction of spindle after wiring:
1. Turn on the power switch.
2. Slightly push “INTREMITENT” button.
3. Look at the rotating direction of Main Spindle from Tailstock.
4. If it is of anti-clockwise, you’ve got a right wiring.
5. If oppositely, exchange any of two wires among “R” “S” “T” terminals.
**If the power indicating lamp is on but you can not start the motor. Thus, it is
overloaded.
If it happens the current out of limit, the cut-off device will activate immediately. In
this moment, please turn off the power then press slightly the recovery plate near
cut-off device in the control box. It will work again. (electric circuit program as
illustrated on next page)
