Status signalling with LEDs and status messages
Built-In Test Equipment
The EXPLORER 3075GX 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

on page 5-3 and
Means of signalling
The EXPLORER 3075GX provides various methods for signalling the system status. There are
LEDs
on the front panel of the ACU to signal Power on/off, Logon and Fail/Pass. There is
also the built-in web interface of the ACU which 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
