8.2.2 Controller Service Call Messages
Controller
error messages
result from failure in either hardware
or software.
Some controller
error messages
occur during
startup
tests. The messages
mean that the controller
is malfunctioning,
but is still able to display the error
massage.
Certain
conditions
can also be detected
during controller
reset, on
insertion
of a cartridge,
and at other times after the completion
of power-up
initialization.
An error stops the test sequence,
the unit goes off line, and the
alarm
sounds.
The controller
will attempt
to recover,
if possible.
If the
problem
is not found during initialization,
but recurs during operation,
most
likely the fault is in the hardware.
