Data Logging on RCI Systems
Example Load Lift
Suppose a driver lifts a load and luffs out. If we assume the SWL % generated at the
edge of the load chart is sufficient to cause a log to record then as soon as the driver
exceeds the m aximum radius on the chart, the ac tive log cycle com pletes and is
written to the logger prior to beginning an "out-of-chart" log cycle.
The ou t-of-chart cycle continues until the driver luf fs the cra ne back into a saf e
condition. As soon as the safe condition is achiev ed, the out-of-chart logs (one for
max. load and one for max. radius) will be stored to the logger.
Because the crane is now back in a safe condition, a new logging cycle begins. When
the driver finally puts this lo ad down (assuming he does not luff off the chart again)
the normal log cycle completes and another log is written to the logger.
Hence, alth ough the driver has lifted only a single load and luffed it to several
positions, the actual load has been reco rded a total of 4 times. This example serves to
illustrate that if the crane is con tinually working on it's outer radius, the Logger will
fill very quickly.
It should be noted that if motion cut is connected and the display is not in over-ride,
luffing to the out ra dius limits of the loa d chart could cause the crane to osc illate as
motion cut activates. In this case many logs may be recorded.
