Setup & Operation
1.3.2 Diagnostic Lights
See Figure 1-2.
LED indicator lights are provided on the encoder sensor housing and the
display circuit board and H-bridge module inside the Simple Set control box. Observing
the LED lights during operation can help identify problems with the sensor, drum switches
or Simple Set control.
During normal operation:
As the up/down gearbox shaft spins to move the saw head up or down, the sensor
LED will illuminate and brighten. After each complete revolution of the shaft, the
LED will turn off then illuminate and brighten.
In manual mode, both control box LEDs will illuminate red when the drum switch is
activated in the down direction and green when the up/down drum switch is acti-
vated in the up direction. Both LEDs will turn off when the drum switch is released.
In auto mode, both control box LEDs operate the same (green) in the up direction
as in manual mode. When the drum switch is bumped in the down direction, both
LEDs will illuminate red and then the display LED will immediately turn off. When
the blade reaches the increment value set by the Simple Set control, the LED on the
H-bridge will turn off. If the drum switch is held down or the saw head coasts past
the increment, the H-bridge LED will illuminate green indicating the blade will move
up to return to the increment value. When the blade reaches the increment value,
the H-bridge LED will turn off.
