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.
POWER
FLASHING indicates that there is a
fault in the system power supply.
Shut down the TSS-2470 Time Delay and
contact 360 Systems Customer Support for
further hardware diagnosis.
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 TSS-2470 Time Delay and
contact 360 Systems Customer Support for
further hardware diagnosis.
Other Error Indicators
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.
Repairs should be performed only by qualified
electronics technicians.
