Meaning for the LMV5x system
Fault with Base Unit (LMV5)
Program stop was activated.
System has stopped at the parameterized position
Program stop in Phase 24 (driving to Prepurge position) active.
Program stop in Phase 32 (Prepurge) active
Program stop in Phase 36 (Ignition position) active
Program stop in Phase 44 (Interval 1) active
Program stop in Phase 52 (Interval 2) active
Program stop in Phase 72 (driving to Postpurge position) active
Program stopin Phase 76 (Pospurge) active
Start release gas = off
System parameterized for 1-detector operation but 2 flame
signals present
Fault during key value check
Number of time block in which the fault was detected
Time block overflow
Number of time block in which the fault was detected
Stack error
Stack overflow
Value dropped below preset minimum limit
Test values in stack range exceeded
Faulty reset state has occurred
Internal communication (µC1 <> µC2)
After initialization, EEPROM page is on ABORT
(last parameterization was possibly interrupted due to a power
failure)
Page number

Corrective action
Deactivate the program stop if no longer required.
Check the configuration of Terminal X7-03.02.
Deactivate terminal if not used. See section 4 as a guide
for configuration of the terminal.
Check flame detector wiring. If two detector operation is
desired, configure the LMV52 for this type of operation.
See section 4.
If fault occurs sporadically improve EMC. If fault occurs
continously, replace LMV5
1) Reset the LMV5
2) If fault occurred after changing a parameter, check
the parameters that were last changed.
3) If fault cannot be rectified by the reset: Restore
parameters form the AZL to the LMV5
4) Replace the LMV5
