Configuring User
Variables
LSI-Robway stores the load-charts, crane geometry, default alarm and motion control settings, default
data logging parameters, fine-tuning settings, and other useful user variables in the memory of the
RCI-4100 at the time of manufacture. As this information may vary from crane to crane, even if they
are of the same model, the RCI-4100 allows the installer to change these variables on site. These user
variables include dimensions such as slew-offset, maximum falls for main/aux winches, maximum line-
pulls, sheave diameters, etc.
The actual values of these variables are listed in the RCI System Configuration Documents in
Attachments . To verify or change the current value of any of these user variables follow the procedure
at Section 7.1.2 Using Calibration Functions.
CAUTION: THE VALUE OF THESE VARIABLES IS VERY IMPORTANT AS THEY AFFECT
THE SAFE OPERATION OF THE RCI-4100 INDICATOR. THEREFORE THE
VALUES OF THE USER VARIABLES MUST BE CHECKED AND CORRECTED
IF NECESSARY BEFORE PROCEEDING WITH FURTHER CALIBRATION OR
OPERATION.
7.4.4.
Verifying Operation of Sensors
NOTE: Before you start calibrating the RCI-4100, you must make sure that the sensors are
working correctly and their signals are reaching the RCI-4100.
The RCI-4100 'sees' the crane and its surroundings through sensors. The signals from these sensors
are represented as numbers inside the RCI-4100. The range of possible numbers is 0 to 4095 for each
sensor.
The RCI-4100 allows the user to view either the UNCALIBRATED or the CALIBRATED signal from a
given sensor(
refer RCI System Configuration Documents in Attachments).
When viewing the UNCALIBRATED signal from a sensor, make sure the number displayed is less
than 4050 and is more than 50 as you work the sensor through its working range. This is the correct
operating range. Also make sure that the numbers displayed in the window are changing in a nice,
smooth manner. If you find that the number is too unstable (i.e. changes by more than 10), then you
should check the connections to the RCI-4100 (refer to Section 8. “Troubleshooting”).
If the signal is less than 50, suspect a short circuit somewhere on that input channel, e.g. the cable to
the RCI-4100 has been crushed and has an internal short circuit in it. Moisture inside the plugs can
look like short circuit too.
If the count displayed in the window is 4095, look for an open circuit on that input channel. e.g.
disconnected lead. This is especially important for the angle sensor.
