Status signalling with LEDs and status messages

5.3 Status signalling with LEDs and status messages
Built-In Test Equipment
The EXPLORER 5075GX has 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 Event list on page 5-3.
Means of signalling
The EXPLORER 5075GX provides various methods for signalling the system status. LEDs on
the front panel of the ACU are used to signal:
• Power on/off
• Logon
• 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 System messages on page B-
1).
