problem.
F11:NOT UP
This message occurs at the start of the DYNAMIC lift if the operator selects a function other than
UP.
F12:TOO MANY
This message occurs if the DYNAMIC lift takes too long.
This message could occur if the UP switch was not released at the end of the dynamic lift.
F13:LOW HEIGHT RANGE
This message occurs at the end of the DYNAMIC lift if the height sensor output did not change
sufficiently to give a reasonably accurate platform height estimate. DIAGNOSTICS / ANALOGS
can be used to check the height sensor output (P8-2 and P8-6) when the platform is fully
lowered and fully raised; a difference of at least 1V is to be expected.
This message could occur if the UP switch was accidentally opened too early (when the platform
is not fully raised).
F14:BAD HEIGHT
This message occurs if the height sensor output (P8-2 and P8-6) is out of range during the
DYNAMIC lift. The height sensor output must be between 1.0V and 4.0V. Check DIAGNOSTICS
/ SENSORS to see the output. A reading of 0V or 5V is probably due to a wiring problem.
F15:CHECK ELEV
This message is given if the elevation switch (P7-5) is open when the platform has been fully
lowered after the DYNAMIC lift.
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.
F16:LOW ELEV������OPEN
This message is given if the elevation switch (P7-5) opened during lift at too low of a height
(below 5%). Check CALIBRATIONS / HEIGHT CALS. The “ElevUp” value shows the recorded
height where the switch opened.
F17:HIGH ELEV������OPEN
This message is given if the elevation switch (P7-5) 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.
F18:LOW ELEV������CLOSE
This message is given if the elevation switch (P7-5) 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.
F19:HIGH ELEV������CLOSE
This message is given if the elevation switch (P7-5) closed during lower at a too high height
(above 25%).
