Error Code Error Cause Elimination
E45
Redundancy error in
the A/D conversion
• The A/D converter on the
processing board and the
redundant A/D converter in
the CPU 80C537 provide
different results.
• Replace processor board.
E46
Error in the A/D con-
verter uPD 7004 of
the processor board.
• No acknowledgment of the
A/D converter uPD 7004
• Replace processor board.
E47
Error in the monitored
write/ read memory.
The CRC verification
of the monitored
write/read memory
provides an incoher-
ent result
• The CRC sign of the moni-
tored write/read memory is
wrong
• The buffer battery is de-
charged (< 2V at 1kOhm).
• Processor board defective.
• Restart the LMI
• Replace buffer battery on
the LMI main board
• Replace processor board.
