This chapter includes the following information:
•
Fault reporting and monitoring, including the status LED and status button, viewing
current faults, and viewing the fault history and fault relay logs.
•
Initialization self-test diagnostic functions.
•
Summary listing all HE4000 faults.
•
Operational problems and their solutions.
6.0 Fault Reporting and Monitoring
The HE4000 has an internal microcontroller that continually performs real-time monitoring of
system conditions. When the unit detects a fault, the front panel Status LED is triggered, the fault
is then stored in the fault history log, and depending upon the type of fault, the fault may be
viewed by querying the current faults.
6.1 Status LED
At-a-glance
system status can be quickly determined by checking the tri-colored Status LED
found on the front panel. The following color of the Status LED identifies the state of the HE4000:
•
Green: the unit is operating correctly and has no current faults.
•
Yellow: a current fault is detected.
•
Red: internal hardware faults are detected, or the video or audio encoders are not
processing data.
If the Status LED illuminates yellow or red, the Status Button can be pressed, which will display
the current faults listing.
Refer to the Faults Summary List for a description of the faults and the actions to take to resolve
them.
HE4000 units may have LED indicators that are visible through holes in
the side and rear panel filler plates. These indicators are used by factory
technicians during the production process but are not used during
HE4000 operation. You should ignore these indicators.
