9. Error and Warning Messages
The error and warning flags generated by the MFC010 can be retrieved from Input register numbers 7001
to 7008. The Error and warning flags are split into two pairs of 32 bit long integer values (each filling two
registers locations).

9.1 System Errors
The System Error flags, held as a long integer value in input registers 7001/7002, are an indication of
faults or malfunctions that are present at that moment in the sensor or Front End electronics systems.
Input registers 7005/7006 hold a stored history of which these error flags have been set since the last
“Reset” command, which can be used to monitor and record the occurrence transient error conditions.
(See Output Coil Number 1008 on page 39 for details of how to reset the stored Error Flags).
Bit Error Flag Designation
0
CT
Name
: ROM Error
Cause
: Internal integrity checking by the MFC010 processor has detected a
corruption of the main program code memory. Such an error could
lead to a serious malfunction of the MFC010.
Action :
Switch off the MFC010 immediately, do not re-use this unit until the
problem is resolved. Call a service support engineer.
1
CT
Name
: RAM Error
Cause
: Internal integrity checking by the MFC010 processor has detected
a corruption of the main program data memory. Such an error
could lead to a serious malfunction of the MFC010.
Action :
Switch off the MFC010 immediately, do not re-use this unit until
the problem is resolved. Call a service support engineer.
2
CT
Name
: EEPROM Write Error
Cause
: The MFC010 processor is having problems saving configuration
data to the onboard non-volatile memory.
Action :
The unit can continue to be used until a service support engineer
is able to attend, as long as no further configuration changes are
required. See Section 8.6 on page 77 for details of saving the
configuration to the non-volatile memory.
3
CT
Name
: EEPROM Data Corrupted
Cause
: The configuration settings stored in the non-volatile EEPROM
memory have been corrupted, the default values have been
restored to prevent a unit malfunction due to invalid settings.
Action :
Re-check all of the configuration settings and if necessary reset to
previous values. If this error is repeated persistently, call a
service support engineer.
