6.8 Replacing a Height Sensor Probe
If your system is equipped with a mechanical height sensor, you will need to replace the height sensor
probe whenever it becomes damaged.
 NOTE The height sensor probe size is dependent upon which dispensing valve is installed.
If you change from one dispensing valve to another, you may also need to change the
height sensor probe.

To remove and replace a height sensor probe:
1. Verify the following:
• The probe is in the down position.
• The dispensing head is at the top of its Z-axis travel.
• The dispensing head is at the front of the dispensing chamber.
2. Press the
OFF (0) button on the operator’s console and open the hatch.
3. Insert a 0.050-inch hex key through the access hole in the side of the height sensor. If
necessary, rotate the probe until the hex key fits into the setscrew on the probe bushing.
See Figure 6-4.
4. After noting the probe position in the bushing, slowly loosen the setscrew on the bushing and
slide the probe out.
CAUTION! Loosen the setscrew just until the probe slides out of the bushing or the setscrew
may fall out.
5. Slide the replacement probe up through the probe block and into the bushing in
approximately the same position as the removed probe. The bend in the probe should be
approximately even with the tip of the dispensing needle as shown in Figure 6-5.
