Sensor Head Alignment
(Top Mount Configuration)
MTE ™ Series Encoders
1.
Proper sensor alignment may require minor
adjustments to the sensor position with respect to
the scale. This can be performed easily using the
sensor’s LED indicator.
The red, yellow, or green Signal LEDs will light
depending on sensor alignment. Slowly move the
sensor by allowing it to slide on the mounting
surface until the green Signal LED, is illuminated.
Optimal alignment will be displayed as a “bright
green” Signal LED.
Confirm that the green Signal LED blinks when
passing over the index. If not, readjust the sensor
in the Y direction and repeat the above procedure.
When alignment is completed, tighten the sensor
mounting screws (0.37Nm [3.3 inch-lbs.] maximum
torque).
2.
Confirm that the Signal LED remains green over
the full range of motion by sliding the scale past
the sensor. The green Signal LED must remain on
over the entire range. If not aligned over the entire
range of motion, loosen the sensor mounting
screws and repeat steps 1 and 2.
The LED will, and should, blink when passing
the index mark.
