Relationship Drawing
In the relationship drawing above, several parts have been removed for clarity, its purpose is to
show the relationship of annotated parts.
The flow controller housing (1) houses the sensor vane (left hand side as viewed). The sensor is
mounted on the bracket (2) that in-turn is mounted on the Transport Base Casting (3). The casting
guides the printer table (not shown). The table lifts the tooling plate (4).
When the table is at home, the sensor is in the vane and it has switched from normally closed, to
open. This tells the software that the tooling table is in a safe position to move.
Testing the sensor:
1. On the HMI Navigate to Service\Diagnostics\Chase.
2. Select Unload Stencil.
3. Open the front cover.
4. Remove the stencil.
5. Close the cover.
6. Press the System button.
7. Select Table And Conveyor Lift.
8. Observe the High Flow Vac Table Present Sensor indicator.
9. Select Vision Height. The indicator should switch from ON to OFF.
10. Observe the warning and select Confirm.
11. Select Home. The indicator should switch ON.
