10-6 Height Sensor
Software Setup
During the software setup process, you can assign values to control various Height Sensor
parameters.
In FmNT you can control:
• Up and Down Speed and Acceleration of the dispensing head during a height
sense
• Maximum Search Depth that the dispensing head will descend in search of the
substrate
• Retract Distance after a height sense
TIP Make sure that your Height Sensor is properly set up prior to
programming.
To set up the Height Sensor in FmNT:
1. In the Main Window, click on Configuration.
2. Select Setup Height Sensor from the drop down menu.
The Setup Height Sensor dialog box opens, showing the various configurable
parameters.
3. Select a Mode.
> If your dispensing system is equipped with a Height Sensor, you will have two
options available, Height sense always and Height sense on command. See On-line Help for
explanations of each mode.
> If your dispensing system is not equipped with a Height Sensor, you must use
FmNT Tools to tell your dispensing system that no Height Sensor is present. Once
your system has been configured for No Height Sensor, you will have several
options available. See On-line Help for explanations of each mode.
TIP Up Speed, Down Speed, Acceleration, Maximum Search Depth
and Retract Distance values are all set at the Asymtek factory prior
to shipping, and should not need to be changed. However, if you
experience problems with your Height Sensor performance, use
these parameters to try and correct the problem. See On-line Help
for explanations of each mode.
4. Click on OK.
? NOTE After installing or making adjustments to the Height Sensor, you
must run a Valve Offsets or Calculate Master Offsets routine. This should be
done every time you change the needle.
