F33:REJECT CURVE
The DYNAMIC pressure curve is unacceptable.
There should be a lowest pressure about halfway through the lift (i.e.: near 50% height); the
lowest pressure measured is at too high a height.
Check for proper weight in the platform and check pressure sensor and lift cylinder hydraulics.
F34:REJECT CURVE
The DYNAMIC pressure curve is unacceptable.
There is not enough difference between the initial pressure peak and the minimum pressure.
Check for proper weight in the platform and check pressure sensor and lift cylinder hydraulics.
F40:REJECT DELTA
This message indicates that there is not enough difference between the loaded & empty
pressure.
This message could occur if the platform were not properly loaded during the STATIC LOADED
phase, or if the platform were not properly empty during the STATIC EMPTY phase.
This message could also occur if the wrong pressure sensor was fitted (e.g.: a 5000psi sensor
when a 3000psi one is needed).
Check CALIBRATIONS / HEIGHT CALS; the “Height” indicates the first height at which there
was insufficient difference and the “Up” and “Down” values show the loaded pressure (first) and
the difference between loaded and empty pressure (second).
F42:LOW PRESSURE
This message indicates that the pressure is too low (0.5V or less) when the elevation switch
opens during the DYNAMIC lift.
This message would occur if the pressure sensor was disconnected, or if there were some other
wiring error.
Check DIAGNOSTICS / SENSORS to check the pressure.
F43:HIGH PRESSURE
This message indicates that the pressure is too high (4.5V or more) when the elevation switch
opens during the DYNAMIC lift.
This message would occur if the wrong pressure sensor was fitted, or if there were some other
wiring error.
Check DIAGNOSTICS / SENSORS to check the pressure.
F44:LOW PRESSURE
This message indicates that the pressure is too low (0.5V or less) at a STATIC measurement
point.
This message would occur if the pressure sensor was disconnected, or if there were some other
wiring error.
Check DIAGNOSTICS / SENSORS to check the pressure.
F45:HIGH PRESSURE
This message indicates that the pressure is too high (4.5V or more) at a STATIC measurement
point.
This message would occur if the wrong pressure sensor was fitted, or if there were some other
wiring error.
Check DIAGNOSTICS / SENSORS to check the pressure.
