LMV5 program operating phases
The AZL user interface, shows the program operating phases in the following order
HOME RUN (Phase 10)
STAND BY (Phase 12)
STARTUP I (Phases 20, 21) Waiting for Start Realase
STARTUP II (Phase 22) Start Fan on
STARTUP III (Phase 24) Driving to Pre-purging
STARTUP IV (Phases 30 ... 34) Pre-purging
STARTUP V (Phase 36) Driving to Ignition Pos
STARTUP VI (Phase 38) Ignition Pos
STARTUP VII (Phases 40, 42, 44) Fuel Release1
STARTUP VIII (Phases 50, 52) Fuel Release2
STARTUP IX (Phase 54) Driving to Low-fire
OPERATION I (Phase 60)
OPERATION II (Phase 62) Shut-down Low-fire
SHUTDOWN (Phase 70)
SHUTDOWN (Phase 72) Driving to Postpurge
SHUTDOWN (Phases 74...78) Postpurging
SHUTDOWN (Phase 79) Test Air PressSwitch
VALVE PROVING (Phases 80 ... 83)
SAFETY PHASE (Phase 01)
LOCKOUT (Phase 00)
At burner startup, the AZL display will show the various phases of the startup program one by one, until it reaches normal operation
phase (Phase 60).
LMV5x controller is factory set. By closing the thermostatic series and once the startup sequence is accomplished (from pahse 12 to
pahse34), the burner is driven to the factory-set ignition position (pahse 38).
Then the fuel/air ratio curve must be set, until the maximum load limit (100% output). During the setting, the actuators move to position
according to the curve points set. While the actuators move, always check the combustion analisys, point by point, and the fklame sta-
bility. In this phase, some temporary points can be set and cancelled successively. Once the requested output is reached, the curve
could be optimised according to the flue gas analisys.
It is recommended to check the gas flow rate on each curve point in order that it corresponds to the actual burner output at that point.
Once all the curvepoints are set, LMV will set the points according to the output increasing order.
Example: if Point4 is set at 50% load and Point5 at 40% load, LMV will automatically assign Point4 to 40% and Point5 to 50%.
CAUTION! The procedure requires a password: qualified personnel only must check all changes to combustion parameters
by means of the combustion analyser. Remember that the password will elapse if no key is pressed for a certain period. The
unit will ask for the password again.
