User Variables
ROBWAY stores the load-charts and crane geometry in the memory of the RCI-1550 at the time of
manufacture. As this information may very from crane to crane, even if they are of the same
model, the RCI-1550 allows the installer to change crane information on site. These user variables
include dimensions such as slew-offset, maximum falls for main/aux winches, maximum line-pulls,
sheave diameters etc.
( refer to function code listing at the end of this manual )
The actual value of these variables are printed on a configuration sheet which is supplied with the
system and a copy of it is also attached to this manual.
To verify or change the current value of any of these user variables follow the procedure below:
 Enter calibration mode,
 Select the correct function code from the listing then using the UP/DOWN keys ramp to that
function code and press ENTER,
 If you want to change the value use the UP/DOWN key to select the new value then press
the ENTER key,
 If you only want to verify the current value press the CANCEL key when finished viewing,
 Now you should be back at the F-xx prompt and can continue on with the next operation.
Please note that the value of these variables is very important as
they affect the safe operation of the RCI-1 550 indicator. Therefo re
the values of the user variables must be c hecked and correcte d if
necessary before proceeding with further calibration or operation.
