System Errors

This section discusses system error messages that may be displayed by the generator from time to time.

Power - on Self Test Messages

The integrity of the data stored in non-volatile memory is checked every time the 801GX is turned on. The following tests are performed:

1.The system configuration memory is checked. The memory remembers what the generator was doing when it was last powered down. The memory also stores all system wide parameters such as calibration factors and the light meter size. It is also checked to see if it is compatible with the current version of operating firmware. If every- thing is in order, then the generator goes on to step 2.

Otherwise, a "System corrupt!" message is dis- played for 2 seconds. This message is immedi- ately followed by a "Memory blank" message, which is displayed for 2 seconds while the for- mat memory is re-initialized. Memory initializa- tion involves clearing the entire non-volatile memory and loading it with factory default data. Any and all data created or edited by the user will be wiped out. The calibration factors are restored to the original values used at the fac- tory to test and calibrate the unit. The generator then continues with step 3.

❖System corruption is very rare. It may be an indication of a bad memory backup battery or a damaged generator.

❖If you update the firmware EPROM in your unit, your system will appear to be corrupt at the next power-on.

2.The remainder of non-volatile memory is checked to see if any data has been corrupted since the
