Variable Pressure Optimization (VPO)

Connections:

• The Variable Pressure Optimization (VPO) Gauge is located on the lower left of the Head faceplate.

• The Variable Pressure Optimization (VPO) Knob is located on the left side of the Head just under the faceplate.

Controlled by:

• The Variable Pressure Optimization (VPO) feature is controlled by air pressure.

• There are test buttons on the Air Valve Assembly to evaluate each of the mechanical functions for the Clamps Activation, Head Lift and the Blade Cartridge Plunge for troubleshooting.

• The ECU/Driver Pack controls the electrical functions of the Clamps Activation, Head Lift and the Blade Cartridge Plunge.

Troubleshooting:

• The VPO Head is not Lifting/Lowering to the material:

  • Check the Air Compressor and make sure it is on.

  • Check the Air Lines to make sure they are not kinked.

  • Check the ECU/Driver Pack connections into the back of the Emergency Stop Button/Control Panel, Gantry and the Computer and make sure they are plugged in tight.

  • Turn off the ECU/Driver Pack close the software. Turn on the ECU/Driver Pack restart the software.

  • Check the Head Lift in the Actuator Valve in the Air Valve Assembly located in the Gantry; the Air Valve Assembly may need to be replaced.

• The Blade Cartridge in the VPO Head is not plunging:

  • For the Z Series, make sure that the pressure for the Variable Pressure Optimization on the Head has not been turned down too far.

  • Check the Blade Cartridge Plunge in the Actuator Valve in the Air Valve Assembly located in the Gantry; the Air Valve Assembly may need to be replaced.
