4.2 Verify Sensor Mounting Surface Height
Step Action
1. Verify that the vertical distance between the reference surface of the sensor and the top of the
scale is as follows:

Tape scale/marker tape after blue protective film is removed: 3.09 mm +/-0.13

Linear or rotary glass scales: 2.93 mm +/-0.13
2. Check the height at a location on the scale where there are no index or limit markers.
4.3 Install Sensor
Step Action
1. Install the sensor on the mounting surface referencing the appropriate datum surface as
shown in the MII6000 Interface Drawings. Use two M-2 screws to loosely attach the sensor.
Note: Do not tighten the two M2 screws at this time.
2. Use benching pins to locate the sensor if the system's mechanical tolerances are adequate.
Refer to the MII6000 Interface Drawings for recommended locations and heights of pins.
