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:CANNOT RUN
There is a shut-down fault on the controller. “EVERYTHING OK” does not show up when you try
to calibrate.
Check HELP message for more information.
F02:NOT GROUND MODE
This message is given if the base/platform selector switch 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 Level Sensor 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.
F07:BAD HEIGHTS
The two Height Sensors are not in agreement at the end of Height Calibration (only on machines
equipped with the optional Overload Sensing System).
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 HEIGHT1
F09:BAD HEIGHT2
This message is given if the height sensor output (P8-2) 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 / SYSTEM” (2a-7) to see the output. This is usually due to a wiring problem.
