6.11 Tensioning the Cables
Periodic tensioning of the dispensing system mechanical drive cables can prevent premature failure of the
cables. For dispensing system operating in a 24/7 production environment, tension the mechanical drive
cables approximately every six months. For systems operating in a single-shift environment (eight hours a
day or less), this should be done once a year.
Tools and Materials Needed:
• Hex Wrench Set
WARNING! This procedure should only be performed by a trained service technician.
6.11.1 Tensioning the X/Y Cables
To tension the X/Y cables (Figure 6-11):
1. Perform a service shutdown, see 2.14 Service Shutdown.
2. Open the dispensing area door.
3. Loosen the X-axis and two (2) Y-axis tensioner screws.
4. Manually move the Z-head in a circle around the entire length and width of the dispensing
area approximately five (5) times.
5. Stop in the center of the dispensing area.
6. Retighten the tensioner screws.
