2. Make sure that all the controller box cables are securely attached.
3. Check the light on the gate boards. The light is located about halfway up the board on the left
side. If this light is not lit, the board is not receiving power. Make sure that all the connections
are secure. Gently tug on each wire to make sure that it is firmly attached.
4. Check the inverter board voltage with a voltmeter to make sure it is receiving power.
5. Go to
Menu > Diagnostics > Gate
. On the second and fourth gate diagnostic screens, the
threshold and sensitivity values are listed for the width and height. The threshold values
should be between 550 and 750. The sensitivity values should be 100. If your values are
incorrect, go to the fifteenth gate diagnostics screen. From this screen you can run an
automatic threshold setting test for the LED beams. When this test is run the CubiScan 125
finds the top and bottom limits and automatically picks the best values. Make sure you move
the gate to the middle of the CubiScan 125 when you run this test. You must save your settings
to retain any changes.
6. Go to
Menu > Diagnostics > Gate
. This screen displays the current status of the LED beams.
Move the gate to the center of the glass platform and clear the platform of all objects. If the
LED beam bars show yellow, please contact Quantronix Technical Assistance at +1 801-451-
7000.
Ultrasound Dimensional Errors
This section describes the various ultrasound dimensional errors that can occur with the
CubiScan 125. For dimensional errors relating to the gate, see
.
Inaccurate Measurement Readings
Complete the following steps if the ultrasound sensors are measuring inaccurately or displaying
dashes in the length, width, or height fields.
1. Make sure the gate is in the home position.
2. Make sure the object you are measuring is correctly placed in the back corner of the CubiScan
125’s measuring platform.
3. Make sure that no objects are touching or leaning against the CubiScan 125.
4. Does the object you are measuring exceed or not meet the measurement range? The
measurement range for the ultrasound sensors is 2.0 in (5.0 cm) to 24.0 x 30.0 x 36.0 in
(60.0 x 80.0 x 90.0 cm).
5. Go to Menu > Diagnostics > Xdcr All. Error messages will be displayed in the length, height,
or width field.
If the CubiScan 125 reports
NoComm
, check the cables leading to that sensor. This message
means that there is no communication with that sensor.
