5. If a Platen Valve (AY) is installed on the system,
remove the cap from the Platen Valve Port located
on the platen.
6. Move the Ram Director Valve (BC) down to lower
the ram again until material appears the Platen
Valve Port.
7. Return the Ram Director Valve (BC) to the neutral
position.
8. Replace the Platen Valve Port cap.
Load the Pump
1. For Tandem systems, ensure the Ball Valves (S) on
the Tandem Block (R) are closed.
2. Move the Ram Director Valve (BC) down to lower
the Ram (AA).
3. At the ADM (AF), press the
soft key to enter
the pump priming mode. Two fields appear on the
screen next to the pump: target pressure (top) and
target flow (bottom).
4. Enter 100 psi (0.7 MPa, 7 bar) as the target
pressure and enter 25 cc/min as the target flow.
NOTE:
Loading the material at the low pressure and
flow rate in step 3 keeps the Pump (AC) from cavitating,
since there is no material loaded in the Pump (AC).
NOTE:
Priming mode has a timer that is shown to the
left of the priming mode icon and counts down when
the priming starts. The default is 5 minutes. If time
expires before you are done loading material to the
system, press the
soft key to restart priming
mode. Your target pressure and flow settings remain
the same.
5. Open the Pump Bleed Valve (AM) and place a
waste container below it to catch material.
6. Press the
soft key to start the Pump (AC).
7. Increase pressure and flow rates on the screen as
necessary to fill the Pump (AC) with material.
8. When a steady stream of material with no air comes
out of the Pump Bleed Valve (AM), close the valve.
9. Press the
soft key to stop the Pump (AC).
Load the Platen Valve and Recirculation
Hose
NOTE:
The following steps only apply to systems that
include the Platen Valve (AY). For systems without a
Platen Valve, go to step 1 in
Load the Hose and Valve
.
1. For Tandem systems, ensure the Ball Valves (S) on
the Tandem Block (R) are closed.
2. Place the Recirculation Hose (ZB) into a waste
container.
3. While still in pump priming mode and with the
target pressure still set at 100 psi (0.7 MPa, 7 bar)
and the target flow at 25 cc/min, press the
soft key to enter the platen depressurization mode.
4. Press the
soft key to start the Pump (AC).
5. Increase pressure and flow rates on the screen as
necessary.
6. Run the Pump (AC) until a steady stream with no air
flows out of the Recirculation Hose.
7. Press the
soft key to stop the Pump (AC).
8. Press the
soft key to exit the platen
depressurization mode.
9. Move the Ram Director Valve (BC) to the neutral
position.
10. Remove the cap from the Platen Valve Port.
11. Install the Recirculation Hose (ZB) to the Platen
Valve Port and tighten until secure.
NOTE:
It is important to load the Platen Valve (AY) and
Recirculation Hose (ZB) with material before connecting
it to the Platen Valve Port to ensure no air is introduced
into the material. Failure to follow these steps could
cause air pockets in the material.
Load the Hose and Dispense Valve
NOTE:
For Tandem systems, ensure that the previous
four sections are completed for both ram supply units
before performing these steps.
1. On a Tandem system, open the Ball Valves (S) on
the Tandem Block (R).
2. Place a waste container below the Dispense Valve
(A).
