4.3-18 Flash Code F19: High Elev.close
1. This message is given if the elevation switch (P2-10) closed during lower at a too high height (above
25%).
When the switch is closed, overload detection is normally disabled but if the switch closes -
above 25%, the platform is too high to allow disabled overload. Check CALIBRATIONS / HEIGHT
CALS; the “ElevUp” value shows the recorded height where the switch opened.
4.3-19 Flash Code F20: Height<>0%
1. 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. -
4.3-20 Flash Code F21:Height<>0%
1. This message occurs if the platform height is not 0% before the platform is raised during either STATIC
lift.
The platform must be at 0% height when it is fully lowered. Check DIAGNOSTICS / SYSTEM -
to check the height.
4.3-21 Flash Code F22:Height<>100%
1. This message occurs if the platform height is not 100% after the platform has been fully raised during
either STATIC lift.
The platform must return to the same height each time it is fully raised. Check DIAGNOSTICS -
/ SYSTEM to check the height.
4.3-22 Flash Code F23:Height<>100%
1. This message occurs if the platform height is not 100% before the platform is lowered during either
STATIC lift.
The platform must be at 100% height when it is fully raised. Check DIAGNOSTICS / SYSTEM -
to check the height.
4.3-23 Flash Code F24:Too Many
1. This message occurs if too many static measurements are taken during either STATIC lift or lower.
It is likely that there is a problem with the lift cylinder pressure; the GP102 should only need -
about 10 measurements for most vehicles. The SETUPS / HEIGHT SETUPS / MIN LIFT time
could be increased to force a longer time between static measurements, but this should not
be necessary.
4.3-24 Flash Code F25:Check Elev
1. This message indicates a problem with the elevation switch (P2-10) during the STATIC phases.
The switch is either staying closed to a higher height, or staying open to a lower height, than -
that recorded during the DYNAMIC phase.
4.3-25 Flash Code F26:Check Elev
1. This message indicates a problem with the elevation switch (P2-10) during the STATIC phases.
The switch is opening or closing at a different height than that recorded during the DYNAMIC -
phase.
