Device Display Meaning for the LMV5x System Corrective Action
45 Any # Locked by SLT Shutdown via safety limit thermostat (SLT) test
SLT was activated and safety shutdown was triggered
(usually by the safety loop opening)
Any #
Program stop was activated. System has stopped at the
01 Program stop in phase 24 (driving to prepurge position) active.
02 Program stop in phase 32 (prepurge) active
03 Program stop in phase 36 (ignition position) active
04 Program stop in phase 44 (interval 1) active
05 Program stop in phase 52 (interval 2) active
06 Program stop in phase 72 (driving to postpurge position) active
07 Program stopin phase 76 (postpurge) active
47 Any #
No Start Release
for Gas
Start release gas = off
Check the configuration of terminal X7-03.2. Deactivate
terminal if not used. See settings section as a guide for
configuration of the terminal.
Any #
System parameterized for 1-detector operation but 2 flame
signals present
00 Parallel operation with 2 flame detectors
Any # 2 flame signals present on external flame safeguard See corrective action based on diagnostic code.
01
Parallel operation of external flame safeguard via contact and
internal flame detector evaluation
When using an external flame safegaurd via terminal
X6-01.3 (HeavyOilDirStart = ext.FlameGd), there must
not be a flame detector connected to the LMV5.
02
Parallel operation of external high-temperature safeguard via
contact and internal flame detector evaluation
When using a high-temperature safegaurd via terminal
X6-01.3 (HeavyOilDirStart = HTempGuard), only one
flame detector may be connected to the LMV5 for low-
temperature operation.
Any # Fault during key value check
00..07 Number of time block in which the fault was detected
Any # Time block overflow
00..07 Number of time block in which the fault was detected
51
Internal Fault
Basic Unit
If fault occurs sporadically, reduce electrical noise.
If fault occurs continuously, replace LMV5.
LMV5
Programstop
active
Fault with Base Unit (LMV5)
2 flame signals

50
48
2 Flame Signals
with 1 Detector
Operation
Check flame detector wiring. If two detector operation
is desired, configure the LMV52 for this type of
operation. See settings section.
49
Deactivate the program stop if no longer required.
