CALIBRATION TROUBLESHOOTING; Failure Messages
During calibration, various problems can be detected by the that prevent successful calibration. These
problems are reported with a flashing message including an “F” code. The following descriptions are
helpful in solving the problem:
F01:CHECK HWFS
This message is given if the start-up tests have not completed.
Check HELP message for more information.
F02:NOT GROUND MODE
This message is given if the machine is not in ground mode (P2-2 must be high).
Calibration can only be carried out in ground mode.
F03:NOT STOPPED
This message is given if any function switch is closed. Check DIAGNOSTICS /
SWITCHES to see which function switch is closed.
F04:TILTED
This message is given if the machine is tilted. Calibration must be carried out
with the machine level. If the machine is level, perform the Tilt Calibration
procedure above.
F05:BAD HEIGHT
This message is given if the height sensor output (P4-3) is out of range at the
start of calibration. The height sensor output must be between 1.0V and 4.0V.
Check DIAGNOSTICS / SENSORS to see the output. A reading of 0V or 5V is
probably due to a wiring problem.
F06:CHECK ELEV
This message is given if the elevation switch (P2-10) is open at the start of
calibration, when the operator has confirmed the “PLATFORM DOWN?”
question.
If the platform is down, check the elevation switch wiring.
F08:CHECK ELEV
This message is given if the elevation switch (P2-10) is closed at the end of the
DYNAMIC lift, when the platform should be fully raised.
This message would occur if the UP switch was accidentally opened near the
start of the DYNAMIC lift.
If the platform is fully raised, check the elevation switch wiring.
F09:BAD HEIGHT
This message is given if the height sensor output (P4-3) is out of range at the
start of the DYNAMIC lift. The height sensor output must be between 1.0V and
4.0V. Check DIAGNOSTICS / SENSORS to see the output. This is usually due
to a wiring problem.
F10:BAD HEIGHT
This message is given if the height sensor output (P4-3) is out of range at the
end of the DYNAMIC lift. The height sensor output must be between 1.0V and
4.0V. Check DIAGNOSTICS / SENSORS to see the output. A reading of 0V or
5V is probably due to a wiring problem.
