4.8 Tensioning the Cables
To tension the cables:
1. Remove the X- and Y-axis covers as described previously in this section.
2. Tension the X-axis cables as follows:
a. Loosen the two X-axis tensioner block screws (Figure 4-7).
WARNING! When performing this procedure, loosen the tensioner block screws, DO NOT
REMOVE THEM. Removing these screws will cause the springs to pop. The
system will then need to be returned to the factory for repair.
b. Manually move the dispensing head to the left and then to the right the full length of the
axis. Repeat three to five times.
c. Center the dispensing head along the X-axis and tighten the tensioner block screws.
3. Tension the Y-axis cables as follows:
a. Remove the tooling plate.
b. Loosen the two Y-axis tensioner block screws (Figure 4-7).
c. Manually move the tooling plate to the back and then to the front the full length of the
axis. Repeat three to five times.
d. Center the tooling plate and tighten the tensioner block screws.
4. Tension the Z-axis cables as follows:
a. Manually push the dispensing head down.
b. Loosen the two Z-axis tensioner block screws (Figure 4-7).
c. Manually move the dispensing head up and down the full length of the axis. Repeat
three to five times.
