6.4.4.
Calibrate High Angle
This function is used to calibrate the High Angle.
6.5. Length (Telescopic Cranes Only)
6.5.1.
View Uncalibrated Length Input
Use this function to view the raw counts (or raw data) of the length sensor. Please also Section
7.4.3. “Verifying Operation of Sensors” for details.
6.5.2.
View Calibrated Length Input
The calibrated length can be verified on normal operating mode (operator’s screen). This function
is used to view the calibrated length while still in calibration mode. This is useful when just verifying
accuracy of the length readout and the calibration has not yet been finalised.
6.5.3.
Calibrate Short Length
This function is used to calibrate the Short Length.
6.5.4.
Calibrate Long Length
This function is used to calibrate the Long Length.
6.6. View Uncalibrated Transducer 1 Input
Use this function to view the raw counts (or raw data) of the Main Load transducer (main load sensor).
Please also Section 7.4.3. “Verifying Operation of Sensors” for details.
Function Codes – View Calibrated Transducer 1, Calibrate Low End of Transducer 1 and
Calibrate High End of Transducer 1
are only used on Load Moment-Based systems only and are not
applicable for this crane.
6.7. View Uncalibrated Transducer 2 Input
Use this function to view the raw counts (or raw data) of the Aux Load transducer (aux load sensor).
Please also Section 7.4.3. “Verifying Operation of Sensors” for details.
Function Codes – View Calibrated Transducer 2, Calibrate Low End of Transducer 2 and
Calibrate High End of Transducer 2 are only used on Load Moment-Based systems only and are not
applicable for this crane.
6.8. OFFSET and GAIN adjustment
Software provides a facility to vary sensor offset and gain. However, provided the sensors have been
provided by LSI-Robway with the system, then the default value has been set by the software
programmer to suit the supplied sensors and is best left as is.
CAUTION: GAIN AND OFFSET ARE PRESET IN THE FACTORY AND SHOULD NOT BE
CHANGED UNLESS DIFFERENT TYPE OF SENSOR WITH DIFFERENT
OUTPUT LEVEL HAS BEEN REPLACED.
The RCI-4100 has 8 identical analogue inputs which can be assigned to different types of analogue
signals such as 4 wire differential (full bridge strain gauge types as found in load cells) or single ended
voltage sensors such as length and angle sensors, or 4-20mA sensors.
RCI-4100 uses 12Bit A/D convertors resulting in a maximum raw count range of 4096. The working
range is between 50 to 4050. Below 50 or above 4050 is considered out of range and will flag an error
state.
What is offset?
LSI-Robway analogue input channels are not designed to start at zero signal level, this is to allow for
sensor error detection. Because of this offset, amplification factors would have to be limited to ensure
that the high end doesn’t exceed available raw counts. So if a software offset is introduced to
