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 dur-
ing 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.
If the host computer PC1 needs to be replaced, re-
member to remove the EEPROM D38 from the old
board and mount it on the new one, otherwise all
the following parameters will be lost:
If you forget to do this, recover the information from
the System Configuration Chart (see Section C).
The alarm is captured and stored as soon as it is detected.
Press the RESET pushbutton on the control panel to cancel the
alarm.
F.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 mem-
ory 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.

F.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 er-
ror 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.
If the host computer PC1 needs to be replaced, re-
member to remove the EEPROM D38 from the old
board and mount it on the new one, otherwise all
the following parameters will be lost:
If you forget to do this, recover the information from
the System Configuration Chart (see Section C).
F.3.46 Ceph bay rotated
The DMU bay for the ceph can be rotated of 90° to make the DMU
insertion easier.
The position of the DMU bay is detected by the optoswitch S41:
when the DMU bay is not in the correct position to start an ex-
posure (i.e. it is rotated), the alarm message Ceph bay rotated
appears on the display; to reset it, it is enough to rotate the DMU
bay in the correct position.
If the alarm message still persists, this can be due to one of the
following possible causes:
1.
optoswitch S41 broken
2.
wiring between optoswitch S41 and the ceph DMU interface
board PH3, connector X93 damaged
3.
ceph DMU interface board PH3 damaged.
