Alignment
Connect the USB cable to the Alignment Tool with power from either the Universal Power supply or computer
USB port.
The Alignment Tool Signal Level and Sensor head LEDs are now used for alignment. Proper alignment is
indicated by green sensor head and Alignment Tool Signal Level LEDs.
3.
Position the sensor over a section of the scale. Adjust the sensor's Y or q
z directions until the Signal Level and
sensor head LEDs are green.
4.
Move the sensor across the entire length of travel. The LED should be green over the entire length of travel. If
the LED is Yellow or Red, adjust Y and
q
z and refer to the interface drawing to ensure proper mechanical
design. (Passing over an Index will cause the Alignment Tool Index/Limit LED to flash green.)

NOTE:
If you are having any difficulties getting a green light over
the entire travel length, refer to the OPS interface drawing
to check mechanical design. 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.
