NOTICE
Align the Sensor
Software automatically begins in Alignment Mode, with AGC off. Position
the sensor over a section of the scale. Adjust the sensor's Y or 0z direc-
tions until the Signal Level is in the Optimal Green level. Move the sensor
across the entire length of travel. The Signal Level should be in the Opti-
mal Green level over the entire length of travel. If the Signal Level is in
the Yellow or Red areas, adjust Y and Z and refer to the interface drawing
to ensure proper mechanical design. (Passing over an Reference will cause
the Diagnosis Tool Reference/Limit LED to flash green.) Check that Refer-
ence LED blinks as sensor passes over Reference. Tighten sensor mounting
screws. Sensor LED Indicator Indicates signal strength – green for optimal
performance, yellow for marginal performance, and red for improper per-
formance. Sensor LED will blink as sensor passes over Reference. Align-
ment Mode is turned off automatically when you begin sensor calibration.
If you are having any difficulties getting a green light over the entire
travel length, Based on the "Sensor head installation" instructions, page
31, check the mechanical dimensions and their tolerances. Also, check to
make sure the scale is properly installed, the sensor is properly oriented
with respect to the scale, and the blue protective film has been removed
from the tape scales.
