High-Pressure Fluids
High-pressure fluids, unless they are safely contained, are
extremely hazardous. Always relieve fluid pressure before
adjusting or servicing high pressure equipment. A jet of
high-pressure fluid can cut like a knife and cause serious bodily
injury, amputation, or death. Fluids penetrating the skin can also
cause toxic poisoning.
If you suffer a fluid injection injury, seek medical care
immediately. If possible, provide a copy of the MSDS for the
injected fluid to the health care provider.
The National Spray Equipment Manufacturers Association has
created a wallet card that you should carry when you are
operating high-pressure spray equipment. These cards are
supplied with your equipment. The following is the text of this
card:
WARNING: Any injury caused by high pressure
liquid can be serious. If you are injured or even
suspect an injury:
SGo to an emergency room immediately.
STell the doctor that you suspect an injection injury.
SShow him this card
STell him what kind of material you were spraying
MEDICAL ALERT—AIRLESS SPRAY WOUNDS: NOTE TO
PHYSICIAN
Injection in the skin is a serious traumatic injury. It is important
to treat the injury surgically as soon as possible. Do not delay
treatment to research toxicity. Toxicity is a concern with some
exotic coatings injected directly into the bloodstream.
Consultation with a plastic surgeon or a reconstructive hand
surgeon may be advisable.
The seriousness of the wound depends on where the injury is on
the body, whether the substance hit something on its way in and
deflected causing more damage, and many other variables
including skin microflora residing in the paint or gun which are
blasted into the wound. If the injected paint contains acrylic
latex and titanium dioxide that damage the tissue’s resistance to
infection, bacterial growth will flourish. The treatment that
doctors recommend for an injection injury to the hand includes
immediate decompression of the closed vascular compartments
of the hand to release the underlying tissue distended by the
injected paint, judicious wound debridement, and immediate
antibiotic treatment.
Fire Safety
To avoid a fire or explosion, follow these instructions.
SGround all conductive equipment. Use only grounded air
and fluid hoses. Check equipment and workpiece
grounding devices regularly. Resistance to ground must not
exceed one megohm.
SShut down all equipment immediately if you notice static
sparking or arcing. Do not restart the equipment until the
cause has been identified and corrected.
SDo not smoke, weld, grind, or use open flames
where flammable materials are being used or stored.
SDo not heat materials to temperatures above those
recommended by the manufacturer. Make sure heat
monitoring and limiting devices are working properly.
SProvide adequate ventilation to prevent dangerous
concentrations of volatile particles or vapors. Refer to local
codes or your material MSDS for guidance.
SDo not disconnect live electrical circuits when working with
flammable materials. Shut off power at a disconnect switch
first to prevent sparking.
SKnow where emergency stop buttons, shutoff valves, and
fire extinguishers are located. If a fire starts in a spray
booth, immediately shut off the spray system and
exhaust fans.
SShut off electrostatic power and ground the charging system
before adjusting, cleaning, or repairing electrostatic
equipment.
SClean, maintain, test, and repair equipment according to the
instructions in your equipment documentation.
SUse only replacement parts that are designed for use with
original equipment. Contact your Nordson representative
for parts information and advice.
Halogenated Hydrocarbon
Solvent Hazards
Do not use halogenated hydrocarbon solvents in a pressurized
system that contains aluminum components. Under pressure,
these solvents can react with aluminum and explode, causing
injury, death, or property damage. Halogenated hydrocarbon
solvents contain one or more of the following elements:
Element Symbol Prefix
Fluorine F “Fluoro-”
Chlorine Cl “Chloro-”
Bromine Br “Bromo-”
Iodine I “Iodo-”
Check your material MSDS or contact your material supplier for
more information. If you must use halogenated hydrocarbon
solvents, contact your Nordson representative for information
about compatible Nordson components.
Action in the Event of a
Malfunction
If a system or any equipment in a system malfunctions, shut off
the system immediately and perform the following steps:
SDisconnect and lock out system electrical power.
Close hydraulic and pneumatic shutoff valves and
relieve pressures.
SIdentify the reason for the malfunction and correct it before
restarting the system.
Disposal
Dispose of equipment and materials used in operation and
servicing according to local codes.

Item Description
1Servo-Controlled Linear Actuator—This actuator drives the plunger rod into the cylinder cavity to
displace the material.
2Connectors—Interface connections for controller cables.
3Proximity Sensors—The proximity sensors feed positional information to the controller. Two proximity
sensors serve as emergency stops and are are triggered by linear actuator anti-rotation plate. One proximity
sensor indicates that the metering cylinder is full.
4Temperature Conditioning Ports—Connections for the temperature control unit water lines.
5, 6 Inlet (5) and Outlet (6) Valves—These high-cycle valves are mounted to the metering cylinder and control
the flow of material into and out of the metering cylinder. The valves also serve as material inlet and outlet
ports.
7Metering Cylinder—The metering cylinder mounts to the liner actuator through the use of four tie rods.
Positive pressure from a Rhino bulk unloader fills the metering cylinder. A packing gland and plunger rod is
mounted to the metering cylinder. The plunger rod displaces material when the actuator extends.
8Cord Set—Cable connection to system controller or J-box for electric heater functions

Part 1075653--06 E2011 Nordson Corporation
Theory of Operation
Positive pressure from the Rhino bulk unloader fills the
metering cylinder. As the linear actuator retracts,
hydraulic pressure extends the metering cylinder piston
to its starting position. The proximity switches provide
positioning information to the linear actuator and the
system controller.
NOTE: The theory of operation for heated versions is
identical with the exception that the system controller
enables and disables the heater circuit to maintain the
material setpoint temperature.
Operation consists of the 4 phases listed in Table 2.
Table 2 Inlet/Outlet Valve Positions
Operation
Valve Positions
During Operation
Inlet Valve Outlet Valve
Refill Open Closed
Idle Closed Closed
Pre-Pressure Closed Closed
Dispense/Purge Closed Open
Refill Phase
See Figure 2. During the refill phase, the actuator
retracts. The material inlet valve opens. Material flows
from the unloader and fills the metering cylinder.
When the cylinder is full, the plunger is fully retracted and
is registered by the proximity switch. The inlet valve
closes. The metering cylinder is full of material and the
unit is ready to dispense.
Idle Phase
See Figure 2. During the idle phase, the material inlet
and outlet valves remain closed until the dispense
sequence begins.
Pre-Pressure
During the pre-pressure phase, the actuator drives the
plunger into the metering cylinder and pressurizes the
material to a set value. The actuator holds this position.
The controller sends a Ready signal to indicate that the
system is ready for the dispense phase.
Dispense/Purge Phase
See Figure 2. During the dispense phase, the drive
assembly forces the metering cylinder piston into the
metering cylinder. The material outlet valve opens at the
same time and material extrudes proportionally to the
given input signal.
