Any #
Error in connection with data comparison (internal
communication) between µC1 and µC2
01
Timeout during program run synchronization prior to data
02 Timeout during data transmission
03 CRC error during data transmission
05 Timeout during program run synchronization with initialization
10 Error counter "Flame intensity outside tolerance" has elapsed
Check flame detector signal. If ok, and fault re-occurs,
replace LMV5

42 ROM-CRC signature unequal
43 Phase unequal
44 (Key + main loop counter) unequal
04 - Unsuccessful synchronization of the 2 µCs
Fault with Base Unit (LMV5)
02
If fault occurs continously, replace LMV5.
03
LMV5
Internal Fault
Basic Unit
If fault occurs sporadically, reduce electrical noise.
If fault occurs continously, replace LMV5.
