OVERVIEW
Model VC300 Pneumatic Valve Controller
The VC300 is a sophisticated controller able to control the operation of pneumatic dispensing
valves with a spring return closing action or air actuated closing action. The high speed,
internal 5/2 way pneumatic solenoid valve is able to rapidly actuate and shut off the dispense
valve, to prevent drooling and achieve consistent and repeatable dispense results.
The plug & play pneumatic push-in style fittings on the back of the controller, ensure it can be
quickly and easily configured when actuating a pneumatic dispense valve fitted with a
mechanical spring return closing action.
The controllers bright multi-line LED display provides easy user-friendly programming and
visualization of the dispense parameters and conditions. While an integrated pressure
regulator and gauge offer the added benefit in allowing the controller to control both dispense
valve actuation and the fluid pressure being supplied to the dispense valve. This results in a
simple and compact valve system setup, with less external fittings & components being used
at risk of damage and leakages.
Three Operation Modes
A manual mode – The dispense operation is manually controlled by a foot pedal.
A timed mode – Dispenses at a pre-set time for controlled, repeatable shot sizes.
A cycle mode – Continually dispenses at a pre-set time and at a pre-set interval.
One programmable memory slot.
Adjustable fluid output pressure (0-100psi) for setting and controlling pressure of fluid reservoir
connected to the dispense valve.
Compatible with pneumatic dispense valves fitted with a spring return or air actuated closing action
Digital timer display (0.008-99.99 seconds).
7 channel I/O circuit for external control and robot integration
Air input alarm for monitoring consistent system input pressure
Industry standard ¼” air-output connector ensures easy system installation and integration into
workplace environments
Compact & durable aluminum housing designed for industrial work environments.
Worldwide compatible power supply.

5. Valve Close
Air Out Port
At the end of a dispensing cycle, pressurized air will exit this port. It is
used for closing the dispense valve via the “Operating Air Close” / “2
nd
Operating Air Inlet” port on the dispense valve.
The pressurized air that exits this port is equal to the air pressure that is
being supplied to the “Main Air In” port
This port is only designed for optional use when the machine is
connected to a 790HP, VDP150, VMS400, VMP30H, VP300 Fisnar
dispense valve.
Typically, this is only needed when using a high viscosity fluid material,
which prevents the return spring fitted inside the dispense valve, from
creating a fast and positive shut-off actuation.

If this function is not required or cannot be used due to the dispense
valve model connected to the machine, then a blanking plug MUST be
inserted into the port.
6. Exhaust Port
At the end of a dispensing cycle, pressurized air that was used to control
the dispense valve actuation will be exhausted from this Exhaust Port.
7. Fluid Air Out Port
The regulated compressed air set by the pressure regulator and
displayed on the pressure gauge on the machine, will exit from this port.
It is used to allow the safe pressurization of the connected fluid feed
system (e.g. syringe barrel, cartridge, etc.)
If this connection is not required for use (e.g. a fluid reservoir tank is
being used as the fluid feed system with its own individual pressure
supply and regulator), it is recommended that the pressure regulator on
the machine be set to 0psi and a blanking plug be inserted into this port.
8. Main Air In Port
External Compressed air 70-100 psi (5-7 bar) is to be connected here.
To prevent damage to internal pneumatic components of the machine,
make sure that the input air supply is clean and dry.
A 5-micron air filter/regulator (item number 560567) is supplied and
recommended to be used, to ensure the input air supply is clean and
dry.
9. Valve Open
Air Out Port
At the start of a dispensing cycle, pressurized air will exit this port. It is
used for opening the dispense valve via the “Operating Air Open” /
“Operating Air Inlet” port on the dispense valve.
The pressurized air that exits this port is equal to the air pressure that is
being supplied to the “Main Air In” port
Pneumatically operated dispense valves are designed to be actuated
at a minimum pressure of 70psi (4.8bar).
To prevent actuation of the connected dispense valve below the
minimum specified working pressure that may have a negative effect on
the dispense result, we recommend enabling the “Low Pressure Alarm”
function (P10) on the machine and setting the “Low Pressure Limit” (P11)
value to 70psi.

connection between the syringe barrel and “Fluid Air Out” port on the back of the machine.
(If the syringe barrel adapter to be used with the machine has a bayonet fitting attached to
the end of it, make sure to cut the bayonet fitting off from the hose and install the included
push to connect air fitting (1/4” stem x 5/32” tube O.D.) (5779K712) onto the end of the
tubing.)
If the “Fluid Air Out” port is not required for use (e.g. a fluid reservoir tank is being used as
the fluid feed system with its own individual pressure supply and regulator), it is
recommended that the pressure regulator on the machine be set to 0psi and a blanking plug
be inserted into this port.
7.
Connect ¼” OD fluid tubing between the fluid outlet of the fluid feed system and the fluid
inlet fitting on the dispense valve, using the appropriate required fittings. Note, in some
cases e.g., when dispensing high viscosity fluid materials, it may be necessary to use 3/8”
OD fluid tubing.
If a Fisnar QuantX syringe barrel is being used as the fluid feed system to the dispense
valve, then an 1/8” luer lock elbow fitting (5601821) can be used to connect the syringe
barrel directly to the dispense valve. Note, dispense valves fitted with a ¼” NPT female
fluid inlet thread will also require reducer fitting (561861).
