7-8 Troubleshooting
Purge Position Sensor and Stop Bolt Realignment
See Figure 7-1.
1. Remove the feed source from the powder feed center.
2. From the
Color Change menu, touch the Lance/Purge Mode button so that it
displays MANUAL .
3. Touch the LANCE DOWN button to lower the lance assembly. Lower the lance
assembly until the pickup plates (8) fully engage with the purge manifolds (9).
If the pickup plates do not engage the purge manifolds, turn the stop bolt (7) clockwise
one turn and touch the LANCE DOWN button again. Repeat if necessary.
4. Turn the stop bolt counterclockwise until the head is firmly against the bottom of the
linear slide (5). When the stop bolt is firmly in place, lock it into position using the jam
nut (6).
NOTE: Figure 7-1 shows the typical locations of the three sensors on the cylinder rod.
Use these dimensions only as a starting point for aligning the sensors.
5. Loosen the sensor bracket and slide it up and down the cylinder rod until the LED (4)
illuminates. With the LED illuminated, tighten the sensor bracket.
6. Use the LANCE UP/DOWN buttons to make sure that the sensor LED illuminates
when the pickup plates engage the purge manifolds. Readjust the stop bolt and
sensor if necessary.
