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.
