6300/6310 Voltage to Incline Test Results
If not as above, inspect the following:
1. In manual mode, press an incline up or down key. The display should beep once. If not, inspect the
display.
2. Test the transformer voltage (see TESTING - TRANSFORMER.1 in Motor System Operation); Check
for 35 VDC across the orange wires.
3. If LED 5 on the drive board lights or ERR7 appears, recalibrate the incline set and test incline operation
again.
4. If the display beeps when incline keys are pressed, but the drive board incline up and down LEDs don’t
light, inspect the ribbon cable (check continuity). If the ribbon cable is good and the transformer is good,
replace the drive board.
