10-10 Height Sensor
To make large adjustments to the probe height:
CAUTION!
Only an Asymtek-trained service technician should perform this procedure.
1. Raise the Dispensing Head so that neither the needle tip nor the probe tip is touching the work
surface.
2. Make sure the probe is in the gear down (GD) position.
3. Using the 1/16-inch hex key, loosen the probe set screw accessed through the hole on the right
side of the Height Sensor (Figure 10-3).
4. Adjust the probe height by sliding the probe up or down (Figure 10-5).
>
The recommended setting for the probe tip height is between 1.78 and 2.54 mm (0.07 to 0.10
in) below the needle tip. However, visually aligning the probe tip so that the bend in the
probe is flush with the needle tip may be adequate for your dispensing application. Consult
Asymtek Technical Support for further assistance.
5. Tighten the probe set screw and adjust the XY position of the probe.
6. Run the Height Sensor Setup procedure which begins on page 10-7.
