Step #20: “Friction compensation”
This procedure should not be used except under guidance from Rayco Wylie Systems
with the exception of down friction.
All of the factors in this menu, with the exception of down friction, are used to
compensate for static pressure decay over time but significant testing and analysis may
be required before any of these default values are modified. The default screens are
shown below for reference:
Boom down friction compensation should only be done once the no load calibration and
various deflection calibrations have been completed. Only one boom down friction
compensation value is available and it will affect all configurations of the machine.
The down friction factor is best established by trial and error :
1)
Use
“
”
or
“
”
to highlight “friction compensation” and press
“
”
to enter.
2)
Scroll down to “down friction” and press
“
”
to highlight the value for editing,
0.00 indicates that no friction compensation is applied. To begin with, increase
the default value from 0.00 to 0.10 and press
“
”
to confirm.
3)
Press
“save”
to record the change.
4)
Press
“
”
to exit the calibration mode and retest the boom down performance
to establish the effect, return to the down friction calibration and modify as
required.
Step #21: “Transfer” Calibration backup
A copy of the calibration file can be made at any time after completing a calibration step
and should be made once the final calibration is completed.
Note
a USB memory stick
must be connected to connector ‘B’ of the i4500 display unit using a Deutsch to USB
converter lead (RaycoWylie part no. 33V0414) before proceeding.
1)
