Problems That Do Not Produce Error Codes
The load does not vary when I lift a weight.
The load cable or the load sensor is faulty (or both are faulty). Check the load cable for faults. If cable
is good, check the resistance values of the load cell. This, however, does not give the complete story.
Even if the resistances are correct, there is still a chance that the sensor is faulty. Check the view
UNCALIBRATED TRANSDUCER INPUT for that sensor, ensure that the value changes when a load
is lifted. If the value doesn’t change as the load changes then it may be a fault with the sensor or
sensor mounting hardware - ensure that the load is being applied to the load cell correctly (eg sister
plates binding a tension cell, or dynamometer centre sheave damaged/stuck). If the value changes as
a load is lifted then calibration needs to be checked or re-calibrated. If no problem found then replace
the load cell.
The load display is very erratic and displays massive changes in value.
Check the view UNCALIBRATED TRANSDUCER INPUT for that sensor. If the values are flickering by
2-3 counts while the display is changing by say a number of tonnes, then the cause is most probably
calibration. One common cause of this is if different load values were entered for the high and low
calibration without the actual load being altered (or of course there was an error in a load channel
while you were calibrating). In other words you forgot to lift the heavy load! (It happens often). In this
situation the display is confused because the calibration data is telling it that the signal it is seeing
represents both the low load value and the high load value simultaneously. Correct the calibration.
This can also occur if only part of the calibration procedure has been completed. You should expect
strange results if you have not completed the calibration of that sensor.
When the system starts in the morning the displays are erratic, but settle during the day.
This is a common sign of moisture ingress into the display, the connectors, the sensors or the cable.
These should be checked, dried and sealed.
The display does not start.
Check the power supply. Refer to Section 11. “General Specification” for the required voltage range. If
the supply is within range, open the RCI Control Unit and check the fuses.
On start-up the display shows “LCtrl” on top screen and then hangs (boot up not completed).
This is a data logger control error. It happens when the internal data logger has been corrupted or
when an upgraded or new software has been installed. To fix this error, insert and turn the over-ride
key switch ON, then press the ENTER button. The display will show “YES” to confirm. While “YES” is
shown on the screen, press the ENTER button again until the display gets into the normal
initialisation/ set-up routine and then to normal operating mode. Note that this will clear the data log of
all entries.
