The first parameter that must be set is to name the servo. Each servo must be named and at least one
servo of each profile must be named AIR. The table below lists the options for naming the servo and
also to what profiles the servo is tagged.
Place the parameter to be modified between the > < characters and using the MDFY, UP, DOWN and
SAVE keys, select AIR and profile 1 for servo 1. The options for the servo direction are CW (clock-
wise) and CCW (counter-clockwise).
Fireye “D” hole couplings should be used in order to assure a secure connection to the driven mem-
ber. Set screws alone are not recommended as they can come loose resulting in a potentially unsafe
condition. Motor shafts are hardened generally preventing set screws from “biting” in and thus loos-
ening after commissioning. Fireye bulletin NEXBK-1000 provides information on “D” hole cou-
plings.
Move the servo position parameter to between the > < characters. At all times and while in P00
(STANDBY, burner off), the servo can be moved to any position. This is useful for checking the
movement of the servo and driven member. Take care not to overdrive the servo such that the driven
member is attempting to move beyond its mechanical end stop. The servo can be left in any position
as it will be positioned properly during commissioning for all profile setpoints. It is recommended
that all servo positions commissioned by the user be between 3° degrees and 97° degrees. To move

Note: It is necessary to ensure that each motor travels in the correct direction to match
the mechanical configuration of the burner. The CW setting is for a servo to move
counter-clockwise (looking toward the shaft) as the motor is driven toward 90°.
