Code F13: Low Height Range
his message occurs at the end of calibration if the height sensor output did not change sufficiently to give a
reasonably accurate platform height estimate.
his message could occur if the UP switch was accidentally opened too early (when the platform is not fully
raised).
- DIAGNOS ICS / SENSORS can be used to check the height sensor output (P43) when the platform is
fully lowered and fully raised; a difference of at least 1V is to be expected.
Code F15: Check Elev
his message is given if the elevation switch (P2-10) is open when the platform has been fully lowered at the
end of calibration.
his 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
his message is given if the elevation switch (P2-10) opened during lift at a too low height (below 5%).
- Check CALIBRA IONS / HEIGH CALS; the "ElevUp" value shows the recorded height where the switch
opened. Set up elevation switch to manufacturers' specifications and calibrate load.
Code F17: High Elev.open
his message is given if the elevation switch (P2-10) opened during lift at a too high height (above 25%).
- Check CALIBRA IONS / HEIGH CALS; the "ElevUp" value shows the recorded height where the switch
opened. Set up elevation switch to manufacturers' specifications and calibrate load.
Code F18: Low Elev.close
his message is given if the elevation switch (P2-10) closed during lower at a too low height (below 5%).
- Check CALIBRA IONS / HEIGH CALS; the "ElevDown" value shows the recorded height where the
switch opened. Set up elevation switch to manufacturers' specifications and calibrate load.
Code F19: High Elev.close
his message is given if the elevation switch (P2-10) closed during lower at a too high height (above 25%).
- Check CALIBRA IONS / HEIGH CALS; the "ElevUp" value shows the recorded height where the switch
opened. Set up elevation switch to manufacturers' specifications and calibrate load.
Code F20: Height<>0%
his message occurs if the platform height is not 0% after the platform has been fully lowered at the end of
calibration.
he platform must return to the same height each time it is fully lowered.
- Check DIAGNOS ICS / SYS EM to check the height.
Code F28: Bad Height
his message indicates a problem with the height sensor output (P4-3) during calibration. he height sensor
output must be between 0.9V and 4.1V, during calibration; and between 0.4V and 4.6V, during normal
operation.
- Check DIAGNOS ICS / SENSORS to see the output. A reading of 0V or 5V is probably due to a wiring
problem.
