Status signalling with LEDs and status messages
Built-In Test Equipment
The ADU and the ACU have a Built-In Test Equipment (BITE) function in order to make
fault diagnostics easy during service and installation. The BITE test is performed
during:
• Power On Self Test (POST), which is automatically performed each time the system is
powered on.
• Person Activated Self Test (PAST), which is initiated by starting a self test in the web
interface
HELPDESK > Self test
.
For details on error messages after a POST or a self test see
Means of signalling
The SAILOR 100 Satellite TV provides various methods for signalling the system status.
LEDs
on the front panel of the ACU are used to signal:
• Power on/off
• TV Ready
• Fail/Pass
The built-in web interface of the ACU shows any events (BITE error codes) with a short
message describing each error. This is also displayed in the ACU.
In an error situation, one of the following system status messages may be shown:
• ACU POST error
• ADU POST error
• SAFE MODE (plus information about the specific error, see
