Section F
3.43.SOFTWARE ERROR
The microprocessor of the PC1 system control board is checking
the parameters corresponding to the movements of the different
projections stored in the Eprom while they are being used (so
during any movement, such as reset cycle, panoramic projection,
etc.).
If these parameters are not the ones expected, the alarm Software
error is generated.
Possible causes:
(1)
Eprom D31 on the PC1 system control board defective
(2)
PC1 system control board defective

The alarm is captured and stored as soon as it is detected.
Press the RESET pushbutton on the control panel to cancel the
alarm.
3.44.SYSTEM CPU FAIL: E2PROM CHECKSUM
At the system power on, the microprocessor of the PC1 system
control board tests the EEPROM memory: if an error in the memory
is detected, the alarm System CPU fail: E2prom checksum is
generated.
Possible causes:
(1)
EEPROM memory not readable
(2)
PC1 system control board defective.
Before replacing the PC1system control board, try to reset the
EEPROM by using the Reset EEPROM Service Program (for more
details refer to the Service Programs paragraph of this Section F):
if after the reset the alarm still persits, replace the PC1 system
control board.

3.45. SYSTEM CPU FAIL: E2PROM NOT READY
At the system power on, the microprocessor of the PC1 system
control board tests the presence of the EEPROM memory. If an
error in the memory is detected, the alarm System CPU fail:
E2prom not ready is generated.
Possible causes:
(1)
PC1 system control board defective
(2)
EEPROM not present.
