Verify power to the machine

CNC Router Online Help and Troubleshooting Guide

Verify Power:

To verify power to the machine, you must first ascertain which Controller box you are using.

LC / LP Controller box:
> Check the diagnostic LEDs on the front.

If PC is lit and no other LEDs are lit, the controller box is not receiving any external power. Verify the Power switch is on. Verify the power cable is plugged in and the outlet it is plugged into is live. Check the fuses in the Power receptacle.

If the PC, +5, +12, +24 lights are lit (ready is irrelevant in this scenario) and the +48 is not lit, the motor fuse inside the control box is blown. After performing Lock out power, replace the fuse with 5x20mm 10A 250v cartridge fuse.

LC Plus Controller box:
> Check the diagnostic LEDs on the front.

If the 24v LED is not lit, the controller box is not receiving any external power. Verify the Power switch is on. Verify the power cable is plugged in and the outlet it is plugged into is live. Check the fuses in the Power receptacle.

Servo Box 1,2:
> If the fan is not blowing in the back of the controller box, the controller box is not receiving any external power.

Verify the Power switch is on. Verify the power cable is plugged in and the outlet it is plugged into is live. Check the fuses in the Power receptacle.
