CE Calibrations
CE Platform Load Calibration
Perform the tilt sensor calibration outlined at the beginning of this section (“ ANSI/CE Tilt Sensor
Calibration” on page 59).
Platform Load calibration must be performed any time:
Significant repairs are made to the elevating assembly
The lift cylinder is removed and serviced or replaced
Any Platform Overload System component is replaced
During the calibration procedure the platform is fully raised and lowered three times:
“DYNAMIC” calibration – fully loaded platform raised & lowered in one continuous movement.
DYNAMIC measurements are taken.
“LOADED” calibration – fully loaded platform raised & lowered with stops to take measurements.
STATIC measurements are taken.
“EMPTY” calibration – unloaded platform raised & lowered with stops to take measurements.
STATIC measurements are taken.
The following procedure must be followed COMPLETELY to calibrate the
GP400 Overload System
.
If any problem is detected, the procedure stops and an Error Message will display on the EZ-Cal.
Explanations of each message and suggested corrections can be found in the section of this manual
following the calibration procedure.
Note:
If the calibration procedure is interrupted, completed phases do not need to be repeated. A
“REDO” prompt will appear – answer “NO” if there is no reason to repeat the phase, or “YES”
if the phase must be repeated (for example because the wrong platform load was used on the
previous phase).
Drive machine to a flat, level surface where it can reach full elevation. Choose a place where the
rated load can be placed in the platform and later removed
without
moving the machine.
Place rated load in platform (see platform labels or serial plate).
Turn selector switch to Base controls.
Plug EZ-Cal into connector P9 on GP400 Control Module. EZ-Cal display reads
