Lower Board LED Diagnosis
LED 1: Transfer indicators. When the power switch is turned on, LED 1 & 2 light up, meaning that
power is supplied to the lower board. These LED’s should remain on while operating the drive motor
and elevation motor. If the LED’s are not lit, check the AC service from the wall outlet.
LED 2: AC power indicator. When the power switch is turned on, LED 4 it will be lit, meaning that
power is supplied to the lower board. This LED should remain on while operating the drive motor and
elevation motor, but while shut off if an error message (E-1, E-2) is shown on the upper board. If this
LED is not lit, and there is not an error message displayed on the upper board, verify that all wire
connections have been properly attached. If the problem persists, check the AC service from the wall
outlet.
LED 3 & 4: Motor indicator. The LED goes on when the drive motor is operating. If the LED is not
lit, voltage is not being supplied to the motor, and the lower board may need to be replaced.
LED 5 & 6: Incline Motor Indicator. When the upper board is commanding the incline motor to move
UP or DOWN, the LEDs go on. LED 5 is for the UP function, and LED 6 is for the DOWN function.
If there is no elevation follow the steps below:
•
Inspect the console cable for pinches and make sure that console cable connections are secure-
replace if necessary.
•
Remove the motor cover.
•
Locate the Elevation LED’s (LED 5& 6).
•
Press “START”.
•
If neither of the LED’s are illuminated- the upper control board is the probable cause.
•
If only the down LED is illuminated- press and hold “STOP” to reset
•
Enter Hardware Test (Eng1) in Engineering Mode.
•
Press “START” twice to begin.
•
Repeatedly press I”.
•
If the elevation increases-the upper control board is the probable cause.
•
If the elevation does not increase- the elevation motor is the probable cause.
