Engaged Piston Position

11.Close the vented ball valve to eliminate the air pres- sure to the system.

12.High light the metering tube entrance position but-

ton ( ).

13.With no air pressure in the system, press the Dis-

pense Request button ( ).

14.Move the piston drive block until it just begins to engage the cylinder using one of the following meth- ods. No material should be dispensed.

Manually Move the Piston Drive Block

In the steps below, ensure pressure is off or piston may activate and pinch fingers against machine block.

a.Perform Pressure Relief Procedure on page 33.

b.Remove the machine cover.

c.With no air pressure in the system, manually push the piston drive block until the piston engages the cylinder and resists movement. A number from 2000 to 2400 will be displayed.

NOTE: If a number outside of this range is displayed, ensure the air cylinder air line connections are not switched and that the linear position sensor is properly installed.

15.Ensure there is no material in the waste container under dispense valve. The piston block moved too far and caused material to be dispensed if there is material in the waste container. Go back to step 14 if the piston moved too far.

16.Press the Enter button ( ) to accept the value or

press the Abort/Cancel button ( ) to keep the previous value.

Prepare Machine for Operation

17.High light the Retract Piston button ( ).

18.Press the Dispense Request button ( ).

19.Open the vented ball valve to enable system pres- sure.

The piston will fully retract when the system is pressur- ized. To avoid injury, ensure the machine shield is installed.

20.Adjust the system air pressure regulator to increase air pressure to standard operating pressure for your application.

21.Navigate to the Shot Mode Screen or Operator Mode Screen.
