to fail.

moving that indicate the lift operation and platform position.

screen for 10 seconds.
2. Look up the number on the correct error code sheet and determine what part on the lift is causing the
failure. Go to the part on the lift that is suspected of causing the failure and look for anything obvious like
magnets missing, broken wires etc. If nothing is found, the next step is to determine if that sensor is send-
ing a signal to the board.
3. Bring the platform to the level that the sensor should be activated using the backup pump if needed. At

numbers, you know that sensor is the problem. You should then check the harness or try another magnet
with the south side of the magnet facing the sensor and see if the number will come up on the display.
4. If the problem is still not found or the harness is suspected, the voltages should to be checked to and

being activated by the magnet. Next check the 12V and 8V wires at the PC board plug leading to the sen-
