COMMAND 05 MAIN BOOM RADIUS/MOMENT
If this is not a prototype calibration, then all radius/moment data will be precalibrated and copied over
for use during crane data reset. There should be no need to perform this routine.
a) Use this command to calibrate the
radius
and
moment
of the main boom. It requires data at high and
low angles retracted, and high and low angles with the boom extended to the prescribed lengths.
b) Carry out calibration at each length. Both high and low angle data must be stored for the calibration to
operate. This acquisition of data is described by the word
CALIBRATION
in the procedure. If for any
reason the data is not stored, the system will warn with the message,
NO DATA
and the data
CALIBRATION
must be repeated.
c) A high angle is one that is higher than 60°. A low angle is lower than 20°. An attempt to acquire data
outside of these limits will result in the warning message "poor angle." When this message occurs as
the result of an error, it can be corrected. The procedure may then be continued using correct
keyboard entries.
d) When this message occurs as a result of requiring data outside the preferred angles, then the data
may be entered using the high angle or low angle key to indicate the unusual angle for which data is
being acquired.
CALIBRATE THE RADIUS/MOMENT OF THE MAIN BOOM AS SHOWN ON THE NEXT PAGES.
