Lockout
At burner startup, the AZL display shows, one by one, the various phases of the start-up program, until it reaches normal operation phase (Phase 60).
LMV5x controller is factory preset. Changing are possible according to the password input
By closing the "thermostat series" and once the start-up sequence is accomplished (from phase 12 to pahse34), the burner is driven to the factory-set
ignition position (phase 38).
The burner remains in that position because this is the only one work point in memory.
The fuel/air ratio curve must be set, until the maximum load limit (100% output).
During the setting, the actuators move according to the curve points. While the actuators move, always check the combustion analysis, point by point,
and the flame stability.
The fuel/air curve points must be set during the commissioning, by a qualified operator.
CAUTION! The procedure requires a password: qualified personnel only must check all changes to combustion parameters by
means of the combustion analyzer. Remember that the password will elapse if no key is pressed for a certain period. The unit will
ask for the password again
ATTENTION! During the cold start phase, it is necessary to set the burner load. Too low output values could damage the
combustion head, blast tube, oil nozzle (if present). The minimum working point must be set by qualified personal.
CAUTION!
:
check the combustion analysis, point by point, and the flame stability.
ATTENTION! Set the real load output percentage at the corresponding curve-point on AZL during the burner regulation.
