Major Probe Adjustments
This procedure can be used to adjust both the height of the Height Sensor probe and
the distance the probe is from the dispensing needle.
To make major adjustments to the probe height:
1. Verify the following:
 The probe is in the down position.
 The Dispensing Head is at the top of its Z-axis travel and at the front of the
dispensing chamber.
 The dispensing needle has been installed.
2. Press OFF (0) on the Operator’s Console and open the Hatch.
3. Insert a 0.050-inch hex key through the access hole in the right side of the
Height Sensor as shown in the figure below.
 It may be necessary to rotate the probe to align the setscrew with the
access hole.
4. Slowly loosen the setscrew on the probe bushing just until you can move the
probe.
Excess loosening of the probe setscrew may cause it to fall out of the
bushing.
5. Adjust the probe so that the probe bend is aligned with the needle tip and that
the probe tip is within 1.0 mm (0.04 in.) from the dispensing needle as shown
Aligning the probe bend with the needle tip automatically provides the
recommended 1.78 to 2.54 mm (0.07 to 0.10 in.) height necessary for
accurate height sensing.
6. While holding the probe in place, tighten the setscrew just until the probe is
held firmly in place and then remove the hex key. If the probe was rotated to
allow access to the setscrew, rotate the probe to its former position.
7. If necessary, make minor adjustments in the needle tip-to-probe bend
alignment as discussed earlier in this section.
8. If no further adjustments are necessary, close the Hatch and press ON (O) on
the Operator’s Console.
9. Perform a Valve Offsets routine. Refer to the FmNT User Guide or FmNT Online
Help for additional information.
