5.7 Adjusting the Z-Head Counterbalance Force
The counterbalance balances the load on the Z-axis. It can be set to accommodate various payloads. When
the Z-head is properly balanced, it enables the system to quickly position the Z-axis accurately. This
procedure assumes the valve(s), cabling, and fluid lines are installed.
To adjust the Z-head counterbalance:
1. Power down the system, see 4.8.1 Post-Production Shutdown.
2. Open the dispensing area door.
3. Disconnect the camera and light source cables.
4. Remove the four (4) screws securing the camera and bracket to the Z-head and carefully
remove the camera and bracket (Figure 5-11) and place to the side.
NOTE If the dispensing head is configured with a tactile height sensor assembly, it is
not necessary to remove it to adjust the Z-head counterbalance force.
