Fault Diagnostics
Front Panel Indicators
The five LED indicators on the front panel are used to diagnose fault conditions. The meaning of each
indicator is noted in the following table. During normal operation all five indicators will be on.
GENLOCK
FLASHING indicates that there is no
Genlock signal, or an invalid signal, at
the GENLOCK GENLOCK GENLOCK GENLOCK input connector.
In installations that use the input
for synchronization, this does not
represent an error condition.
Check the Genlock setting in the On-Screen
System menu.
Check the Genlock cable connections or
signal.
POWER FLASHING indicates that there is a
fault in the system power supply.
Shut down the Broadcast Time Delay and
contact 360 Systems Customer Support for
further hardware diagnosis.
FANS FLASHING indicates that there is a
fault of the internal chassis fan.
Check the chassis fan operation. Replace if
necessary. Do not run the Broadcast Time
Delay without a working fan.
DRIVES FLASHING indicates that there is a
fault in the system RAID array.
Check the RAID array status using
the utility under
START > RAID STATUS.
SYSTEM FLASHING indicates that the CPU fan
is running slow, or stopped; or that the
CPU temperature or voltage is not
within manufacturer’s specification.
Shut down the Broadcast Time Delay and
contact 360 Systems Customer Support for
further hardware diagnosis.
The bottom line of the GUI will announce error conditions, in some cases giving further detail on
the nature of a fault. For example, when the System light is flashing, the GUI may indicate a
temperature error or a power supply voltage that is out of tolerance.
The GPI Outputs are programmed to indicate errors as well. These can be interfaced to an alarm
or warning light in installations where the GUI and the front panel are not visible to control room
personnel. See page 25.
Repairs should be performed only by qualified electronics
technicians.
