Maintenance and Diagnostics
Troubleshooting
Common situations
The following list provides information about problems that an operator might encounter during operation.
Power up
The CNC does not power up when the ON/OFF button is pressed.
1. Verify that the power cord is plugged into the back of the CNC.
2. Verify that the wall circuit breaker is active.
3. Verify that the fuse in the power entry module is functional. Replace if necessary (208142).
4. Open the CNC enclosure and verify that the D6 AC lamp is illuminated on the power distribution board.
See page 121.
5. If the lamp is not illuminated, replace the surge board or the power entry harness (223310). See Surge board
(141287) on page 142 or Power distribution board (141153) on page 121.
6. Verify the connections for the ON / OFF button on the front panel.
7. Verify the green LED light on the motherboard is illuminated. This LED indicates power is reaching the motherboard.
See page 120. If it is not illuminated, replace the ATX power supply (228473), or contact your table manufacturer for
additional troubleshooting.
8. Verify that the green and white wires from the utility and serial isolation board (141307) are connected to the
motherboard.
9. Contact your table manufacturer.
Display
The power switch is on and illuminated, but the screen remains black.
1. Verify that the AC power connections are plugged into the display.
2. Look at the motherboard to see if there is a BIOS fault.
3. Verify that the ambient temperature is within the operating range of the CNC. See System specifications on page 33.
LED
A button, function, or LED on the front panel is not responding when the corresponding switch is activated
by the operator.
1. Go to Setups > Diagnostics > Operator Interface screen.
2. Move or press any of the components on the physical front panel to verify the proper operation on the CNC screen.
If any of these tests fail, replace the individual component on the front panel (see EDGE Pro Ti Parts List for the
appropriate part number).
The “Field power failure” error message is posted on the CNC.
1. Verify that the cable between the utility and serial isolation board (141307) and the power distribution board
(141153) is connected at both ends.
2. Verify that all other cables are properly connected.
3. Verify that the ATX power supply is operating.
4. Verify that the LEDs on the power distribution board are illuminated. See page 121.
5. If the LEDs on the power distribution board are not illuminated, replace the board.
