Fault Code List (Continued)
Fault Code Description
F44:LOW PRESSURE
During static (loaded or empty) calibration, the lift cylinder pressure is out of range (below 0.4V or
above 4.6V).
F48:BAD PRESSURE
At the start of calibration, the pressure sensor is out of range (output must be between 0.3V and
4.8V at all times)
F52:NOT
CALIBRATED!
Something happened to cause calibration to fail – it is recommended to check all sensor wiring for
loose connections, then repeat calibration.
FINISHED!
This display occurs when all calibrations (dynamic, loaded up, loaded down, empty up, empty
down) have been completed, and the CALDATE has been entered.
Be sure to press <ESC> on the display module to exit calibration, before attempting to use the
machine.
GO UP MORE!
During calibration, the operator needs to close the UP or DOWN switch as required to lift or lower
the platform – if the switch is closed in the wrong direction, no fault occurs but the machine does
not move! This display clarifies the error.
GO DOWN MORE!
PLEASE WAIT
During calibration, the Control Module CM1 sometimes delays while waiting for sensor values to
stabilize – this display indicates why nothing appears to be happening.
Non-applicable fault codes
There are additional fault codes that may show up on the Skycoded display panel that does not affect your
machine. If you see the following fault codes, calibrate the load 5.4-8 Calibrate Load Procedure and level
5.4-7 Calibrate Level Procedure of your machine again. If the fault codes continue, contact the Skyjack service
department.
