Installation
WARNING
Disconnect the electrical power and inlet air pressure
to the factory automation system and valve controller
prior to proceeding.
1. Mount the valve securely to the Z-axis of the
robot using the bracket provided for the valve or
another appropriate mounting bracket for other
machines.
2. Connect the motor wires to the valve controller.
The white wire connects to the (+) terminal and
the brown wire to the (–) terminal.
3. Attach the barrel outlet fitting to the end of a
barrel of material to be dispensed.
4. Insert the barrel into the barrel clamp, position as
required, and clamp securely.
5. Trim a length of the supply hose provided to
approximately 80 mm (3 1/8") and push into the
barrel outlet and auger assembly input fittings.
6. Attach the blue end of the barrel adapter
assembly to the end of the barrel. Connect the
bayonet fitting to the valve controller air output.
7. Install an EFD 1/4" long dispensing tip of the
appropriate gauge. (Refer to “Changing a Tip” on
page9.)

Making Adjustments
Dispense time is the primary method of making small
adjustments in deposit size. In general, larger deposits
require longer dispense times, larger diameter tips,
and larger gaps. Be sure to allow settling time (before
dispense) and dwell time (after dispense). Very small
deposits may require chamfered tips. Air pressure
should be set to a point just below where drooling
occurs without the auger turning.
