B B2 2..1 1..1 1 To enter Alignment Mode, push and release
the Cal. button quickly (within a second).
The limit LED’s will begin to blink slowly.
B B2 2..1 1..2 2 Align the sensor by slowly sliding the sensor
on its mounting surface in the Y or
θ
z
directions until the green Signal Strength
LED is illuminated. Tighten the sensor
mounting screws (0.37Nm [3.3 inch-lbs.]
maximum torque).
B B2 2..1 1..3 3 Move the senor over the index mark and
confirm that the green Signal Strength LED
blinks. (If the green Signal Strength LED
does not blink when the sensor passes over
the index, loosen the mounting screws and
repeat the alignment procedure.)

the scale. If the green signal strength LED
remains illuminated over the entire length of
travel (the yellow and red LED’s do not
illuminate), proceed to the next step.
Otherwise, clean the scale and try again. If
cleaning the scale is not successful, loosen
the sensor mounting screws and repeat the
alignment procedure.
