5.3 TEST PROCEDURES
5.3.1 Diverter Valve Sensors Test
The diverter valve is mounted at the rear of the bulkhead. The pump assembly is located on the
front side of the bulkhead.
If viewed from the rear of the printer, a flexible hose from the pump connects to the left-hand port
on the diverter valve; the right-hand side hose connects to the riser pipe. Because of its physical
location, on the other side of the bulkhead, it is important to confirm that any fault lies with the di-
verter valve. To gain access to the sensors requires the removal of the pump, the hoses and the di-
verter valve.

Testing the sensors (this procedure requires two people):

1. Remove the lower rear panel.
2. Open the front cover to gain access to the flow controller valve.
3. Note or mark the position of the flow controller indexer.
4. Fully close the sliding baffle plate.
5. On the HMI Select Menu.
6. Navigate to Service\Diagnostics\Table and Conveyor Lift.
If ON, turn venturi vacuum tooling OFF.
7. Ensure that High Flow Vacuum Pump is set to ON.
8. Check that either the High Flow Vacuum Diverter Valve Actuator Sensor (1) or the High
Flow Vacuum Diverter Valve Retract Sensor (2) is ON.
9. Toggle the Retract High Flow Vacuum Diverter sensor ON/OFF.
10. Check that the high flow vacuum diverter valve actuator sensor and the high flow vacuum di-
verter valve retract sensor indicators toggle: ON/OFF.
11. At the rear of the printer, the vented air flow should be heard expelling from the diverter valve
vent as the retract sensor is activated and the diverter valve opens.
NOTE
If all the above are true, the fault may not be at the diverter valve. If exhaust air is constantly
heard, a leak may exist in the hoses or the tooling plate.
12. Exit Diagnostics.
13. Set the flow controller valve back to the setting, as noted, in step 3.
