Section 5 – Procedures Skycoded Module
Calibration Load - Faults
During calibration, the Control Module CM1 repeatedly checks for possible problems, which might prevent
successful calibration, or subsequently give inaccurate platform load estimates.
If any problems are detected, a flashing error message is immediately displayed and calibration is terminated –
the problem must be resolved, and then calibration must be restarted.
Fault Code List
Most calibration error messages have an “Fxx” number as well as a description, to aid in trouble-shooting.
Fault Code Description
F01:CANNOT RUN
Something is wrong, preventing the Control Module CM1 from running – check the HELP message
(causes include line contactor, valve, or motor wiring errors).
F02:NOT GROUND
MODE
Calibration can only be carried out from base control!
F03:NOT STOPPED The machine must not already be moving when calibration started.
F04:TILTED The machine must be on level ground when calibration started.
F05:BAD HEIGHT1
At the start of calibration, the Angle Transducers are out of range (output must be between 0.9V and
4.1V with Platform fully lowered).
F05:BAD HEIGHT2
F06:CHECK ELEV At the start of calibration, the Angle Transducers require calibration with Platform fully lowered.
F07:BAD HEIGHTS During calibration, the two Angle Transducers disagreed too much.
F08:CHECK ELEV The Angle Transducers require calibration with the platform fully raised.
F09:BAD HEIGHT1
The Angle Transducers are out of range when fully lowered (0%) calibration is recorded (output must
be between 0.9V and 4.1V with platform fully lowered).
F09:BAD HEIGHT2
F10:BAD HEIGHT1
The Angle Transducers are out of range when fully raised (100%) calibration is recorded (output
must be between 0.6V and 4.4V with platform fully raised).
F10:BAD HEIGHT2
F11:NOT UP
When instructed to go up (raise the Platform) the DOWN switch was activated.
F11:NOT DOWN
F12:TOO MANY
More than 500 samples are recorded during dynamic lifting – the machine lifts too slowly.
Increase the value of SETUPS/HEIGHT SETUPS/SAMPLE@ to delay longer between each
sample (do not increase too much, as this will cause inaccurate dynamic load estimates).
F13:LOW HEIGHT
RANGE
There is not enough difference between the Angle Transducers output when fully lowered,
and fully raised (minimum allowed difference is 1V).
Make sure the UP switch is not released before the platform is fully raised.
F14:BAD HEIGHT1
The Angle Transducers output is bad during dynamic lifting (must be between 0.6V and
4.4V always).
F15:CHECK ELEV
The Angle Transducers is open with platform fully lowered at the end of the dynamic
raising / lowering cycle – or the switch changed state more than once.
F16:LOW ELEV.OPEN
The point at which the Angle Transducers are open while the platform was lifting, is too low (it should
open between 5% and 20% height).
F17:HIGH ELEV.
OPEN The point at which the Angle Transducers are open while the platform was lifting, is too high (it
should open between 5% and 20% height).
