Calibration Problems
Failure Messages
Various problems can be detected by the EZ-Cal 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. References in parentheses refer to electrical schematic points.
F01:CHECK HWFS
This message is given if the startup 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 (P7-2 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 (P8-2 and P8-6) 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 (P7-5) 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 (P7-5) 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 (P8-2 and P8-6) 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 (P8-2 and P8-6) 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
