1. Confirm that +5DC is present at the following pads:

Pads 6 and 19 (CE300-4, CE300-40)

Pads 1 and 5 (CE-40GC)
See Section 2.1 Power Recommendations
2. Confirm that ground is present at the following pads:

Pads 2, 8, and 18 (CE300-4, CE300-40)

Pad 9 (CE-40GC)
Use the Sin+ and IW+ signals to confirm alignment (see
Encoder Alignment.)

Verify that the encoder is mounted in the correct orientation with
reference to the scale and scale mounting reference edge. Refer
to the Interface Drawing.

Verify that the sensor has been aligned to the scale and that the
mounting screws are tight. Check the dimensions for the
mechanical mounting holes (and clamps if any) to make sure that
the sensor is correctly located over the scale in the Y and Z
dimensions. Refer to the Interface Drawing.

Check that the scale is firmly mounted and can't jiggle or move in
any direction other than the axis of motion.

Make sure that the scale is clean over its entire length or
circumference.
1. Make sure that the Eval PCB connector is fully seated and
connected.
2. Confirm that +5DC is present at Pin 1 of the 10 pin ZIF connector.
See Section 2.1 Power Recommendations
3. Confirm that ground is present at Pin 2 of the 10 pin ZIF
connector.

Verify that the sensor is mounted in the correct orientation with
reference to the scale and scale mounting reference edge. Refer
to the interface drawings.

Verify that the sensor has been aligned correctly to the scale.

Check that the scale is firmly mounted and can't jiggle or move in
any direction.

Make sure that the scale is clean over its entire length or
circumference.

Confirm proper reflow connection to PCB.
