Troubleshooting Guide
IN
- This light normally dims and brightens as the feed rate switch is turned up or down. If
the light does not correspond to the feed rate switch, the switch has failed or is not wired
correctly.
OFF
- This indicator is active anytime the CL or IL light is active. This light indicates the
shutdown circuit has been activated. If the light comes on without the CL or IL light also
on, the circuit board is wet or defective. If you determine the board is not wet, replace it.
IL
- This light indicates the circuit board has detected a failure of the output circuit protec-
tion or that the power feed motor has been replaced with a motor not provided by
Wood-Mizer. The light will flash about once every second and will deactivate the output
circuit. If the power feed motor is a Wood-Mizer replacement, replace the circuit board.
CL
- This light indicates an extreme overload condition of the power feed motor or a short
in the wiring between the motor and circuit board. The light will flash about once every
second and deactivate the feed system until the problem is corrected.
OUT
- This light normally dims and brightens at the same rate as the IN light when the
feed rate switch is turned up and down. If the OUT light does not correspond with the IN
light, replace the circuit board.
