3. Click on the down arrow under Height Sensor Type and select RT from the drop down menu.

Mode.
> You have three options available, Height sense always, Selective height sense, and
Height sense on command. See the Online Help for details.
TIP Adjusting the Z-axis velocity and acceleration can improve throughput by decreasing the
amount of time it takes to make a height sense measurement. For example, a slow
velocity (1 in/sec) with a high acceleration value (300 in/sec
2
) produces the most accurate
height sensing measurements.
TIP Velocities above 2 inches per second and accelerations above 300 in/sec
2
can result in
large repeatability errors. See “Specifications” on page 10-17 for more information.

NOTE After installing or making adjustments to the Height Sensor, you must run a Valve
Offsets
or Calculate Master Offsets routine (refer to the Machine Offsets Procedures of
this manual).
TIP We recommend that you perform a height sensor setup every time you make adjustments
to the Height Sensor. If you change the needle, perform a
Find Needle XYZ procedure
instead of
Setup Height Sensor. Find Needle XYZ is found on the Setup menu in the
Programming window.
