4.3-26 Flash Code F27:Bad Height
1. his message indicates a problem with the height sensor output (P4-3) during the S A IC phases.
he height sensor output must be between 1.0V and 4.0V at all times. Check DIAGNOS ICS /
-
SENSORS to see the output. A reading of 0V or 5V is probably due to a wiring problem.
4.3-27 Flash Code F30:Bad Heights
1. his message indicates that the recorded heights are not increasing during either S A IC lift, or are
not decreasing during either S A IC lower.
It may be possible to cause this problem by repeatedly opening and closing the UP or DOWN
-
switch during the S A IC phases.
4.3-28 Flash Code F31:Reject Curve
1. he DYNAMIC pressure curve is unacceptable.
An initial pressure peak when the platform lifted cannot be found between 0% and 15% height.
-
Check the pressure sensor and lift cylinder hydraulics.
4.3-29 Flash Code F32:Reject Curve
1. he DYNAMIC pressure curve is unacceptable.
here should be a lowest pressure about halfway through the lift (ie: near 50% height); the
-
lowest pressure measured is at too low a height. Check the pressure sensor and lift cylinder
hydraulics.
4.3-30 Flash Code F33:Reject Curve
1. he DYNAMIC pressure curve is unacceptable.
here should be a lowest pressure about halfway through the lift (ie: near 50% height); the
-
lowest pressure measured is at too high a height. Check the pressure sensor and lift cylinder
hydraulics.
4.3-31 Flash Code F34:Reject Curve
1. he DYNAMIC pressure curve is unacceptable.
here is not enough difference between the initial pressure peak and the minimum pressure.
-
Check the pressure sensor and lift cylinder hydraulics.
4.3-32 Flash Code F40:Reject Delta
1. his message indicates that there is not enough difference between the loaded & empty pressure.
his message could also occur if the wrong pressure sensor was fitted (eg: a 5000psi sensor when a
2000psi one is needed)
his message could occur if the platform were not properly loaded during the S A IC LOADED phase,
or if the platform were not properly empty during the S A IC EMP Y phase.
Check CALIBRA IONS / HEIGH 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).
