F1-1 PRE-REQUISITES FOR BASIC LMV3 SYSTEMS
Before the burner can be classified as in good working condition, there are various pre-requisites
that must be met for the LMV control, burner, and application.
1.
Burner must be in good condition, meaning;
a.
The head must not be melted, cracked, or otherwise damaged.
b.
If applicable, the UV scanner must be positioned correctly to sight the flame. To limit
interference the sight glass must be removed.
2.
Actuators must be mounted properly. Specific attention must be given to:
a.
Actuator shafts must accommodate for angular and parallel shaft misalignment.
b.
Have little to no backlash.
c.
Be robust enough to absorb torque applied (27 in/lbs) to the actuator without causing
damage.
d.
The actuator mounting brackets must be rigid enough to prevent amplifying burner
vibration.
e.
The actuator mounting brackets must also not distort under torque applied.
3.
All wiring to and from the LMV3 control meets applicable local and national standards.
a.
The voltage supplied to the LMV3 control must be within 102VAC and 132VAC and
between 47-63Hz.
4.
Fuel supply must be sufficient to support high fire operation. The gas train must be sized
properly.
5.
A gas analyzer that has been calibrated must be used for setting proper combustion.
6.
A method/calculation for determining firing rate must be known and used. This is used to set
the fuel flow for each of the 1-9 setpoints.
F.2 SQM DAMPER MOTOR
SQM damper motors, with programmable operation direction, are used on the burner to control both gas
and air volumes. Within the AZL display, parameters 601 and 602 can be modified to change
operational direction and reference direction.
F.2-1 OPERATIONAL DIRECTIONS
1.
Counterclockwise Rotation - When the actuator is at 0°, the flat of the “D” shaft is
perpendicular to line
A.
When the position of the actuator reaches 90°, the flat of the “D”
shaft will be perpendicular to line
B.
2.
Clockwise Rotation – When the actuator is at 0°, the flat of the “D” shaft is perpendicular to
line
B.
When the position of the actuator reaches 90°, the flat of the “D” shaft will be
perpendicular to line
A.
DO NOT ADJUST ANY PARAMETER SETTINGS OF THE AIR
SHUTTER ORIENTATION DIRECTION. DOING SO WILL
CAUSE DAMAGE TO BOTH THE AIR SHUTTER AND THE
ACTUATOR MOTOR.
