position depending on the item chosen.
Figure 8 – Pusher Motor Control
4.8 System Status
System Status is located in the System Status block group under the Manual Control group. It informs the
user of a healthy or unhealthy system status, depending on any system errors present. It indicates the user of
continual operational time, number of packages scanned and whether a package is ready to be removed. This
group also contains the system targets to Reset and Shutdown the system if desired.
Figure 9 – System Status
4.9 Tracking Packages
After scanning, all the packages are tracked via the Package Logs page of the User Interface. As Figure 3
demonstrates, packages are listed in order scanned with a sequential numeric serial number and timestamp of
time scanned.
Figure 10 – Clicking the Package Logs Tab Page
4.10 Loading Luggage on Conveyor
Packages loaded are loaded in the LOC1 position tripping the sensor beam informing the system a package is
present. If the system is in automatic control mode, processing will start.
4.11 Picking up Luggage from Conveyor
When a package has been processed through the system via manual or automatic means, the package
terminates at LOC7 waiting to be removed from the system. The Package Ready indication is noted in the

5 Troubleshooting
5.1 Interpreting Failures
Failures are noted on the Sensor/Motor State Information group and in the system status text. Failures will
note which independent system has failed thus requiring an error clear and/or manual investigation of the
system.
5.2 Failure Recovery
System recovery relies on manual investigation and personal knowledge of correct function. Problems
indication failure on the User Interface must be manually investigated and corrected. The system can recover
from several known failures by simply clicking the “clear” link in the system status window when an error
occurs. Otherwise please take following steps:
1.
2.
3.
4.
5.
6.
Investigate indicated motor or sensor failures to see if there are loose connection.
If all connections are solid, try manually operating motor or tripping a sensor to see if they are
functioning.
Click the Reset Button in the Web Interface(refer to section 4.12).
Reset the Robo-Interface (refer to Section 3.5)
Reload image (refer to Section 3.4)
Replace Motors/Sensors that have failures.
