Section 5 – Procedures Load Sensing System
Code F13: Low Height Range
This message occurs at the end of calibration if the height sensor output did not change sufciently to give a
reasonably accurate platform height estimate.
This message could occur if the UP switch was accidentally opened too early (when the platform is not fully
raised). DIAGNOSTICS / SENSORS can be used to check the height sensor output (P4-3). A difference of at least
1V is to be expected.
Code F15: Check Elev
This message is given if the elevation switch (P2-10) is closed when the platform has been fully lowered at the end
of calibration.
This message would occur if the DOWN switch was accidentally opened before the platform was fully lowered. If
the platform is fully lowered, check the elevation switch.
Code F16: Low Elev.open
This message is given if the elevation switch (P2-10) opened during lift at a too low height (below 5%).
▪ Check CALIBRATIONS / HEIGHT CALS; the “ElevUp” value shows the recorded height where the switch
opened. Set up elevation switch to manufacturers’ specications and calibrate load.
Code F17: High Elev.open
This message is given if the elevation switch (P2-10) opened during lift at a too high height (above 25%).
▪ Check CALIBRATIONS / HEIGHT CALS; the “ElevUp” value shows the recorded height where the switch
opened. Set up elevation switch to manufacturers’ specications and calibrate load.
Code F18: Low Elev.close
This message is given if the elevation switch (P2-10) closed during lower at a too low height (below 5%).
▪ Check CALIBRATIONS / HEIGHT CALS; the “ElevDown” value shows the recorded height where the
switch opened. Set up elevation switch to manufacturers’ specications and calibrate load.
Code F19: High Elev.close
This message is given if the elevation switch (P2-10) closed during lower at a too high height (above 25%).
▪ Check CALIBRATIONS / HEIGHT CALS; the “ElevUp” value shows the recorded height where the switch
opened. Set up elevation switch to manufacturers’ specications and calibrate load.
Code F20: Height<>0%
This message occurs if the platform height is not 0% after the platform has been fully lowered during either
STATIC lift.
The platform must return to the same height each time it is fully lowered.
▪ Check DIAGNOSTICS / SYSTEM to check the height.
Code F28: Bad Height
This message indicates a problem with the height sensor output (P4-3) during calibration.
The height sensor output must be between 1.0V and 4.0V at all times.
▪ Check DIAGNOSTICS / SENSORS to see the output. A reading of 0V or 5V is probably due to a wiring
problem.
Code F42: Low Pressure
This message indicates that the pressure transducer output (P4-2) is too low (0.5V or less) at the beginning of
calibration.
▪ Check DIAGNOSTICS / SENSORS to read output.
