Resets the ignition position of the actuator to an invalid value.
Resets the ignition position of the air actuator to a invalid value.
Resets the ignition position of the aux1 actuator to a invalid value.
Resets the ignition position of the aux2 actuator to a invalid value.
Resets the ignition position of the aux3 actuator to a invalid value.
Resets the ignition position of the VSD to a invalid value.
S
This is where actuator curves (fuel air ratio) are set from low to high fire. For an LMV 52, five actuators and
one VSD can be set at every point. Fifteen points can be set from low to high fire.
Colons(:) indicate that the actuator is at the indicated position, and a (>) indicates the actuator is seeking a
new position. If a O2 sensor is attached and activated, (LMV52) the O2 value will also be displayed on the
screen.
When a specific point is selected (Point 2 for example) the LMV5 will prompt if the point is to be changed or
deleted. If change is selected, then the LMV5 will prompt the user to select followed or not followed. If
followed is selcted, the LMV5 will drive the actuators / VSD to the point, and themthe point can be changed.
If not followed is selected, the LMV5 will not drive to the point, but the point can still be changed.
NOTE : When not followed is selected, the effect of actuator changes cannot seen on a combustion
anaylizer. If not followed is selected, extreme caution must be used.
O Mode for firing oil. Range = Two-stage, Three-stage, Modulating Def = Modulating
Sets the low fire load. During normal operation the burner will not modulate below this point. Should be set to
reflect low fire fuel input. On a 10:1 turndown burner, set at 10%. Range = 0 to 100% Def = 0% Typ = 10-
40%
S
Sets the high fire load. During normal operation the burner will not modulate above this point.
Range = 0 to 100% Def = 0% Typ = 100%
