Section 1

Safety

Introduction

Read and follow these safety instructions. Task- and equipment-specific warnings, cautions, and instructions are included in equipment

documentation where appropriate.

Make sure all equipment documentation, including these instructions, is accessible to persons operating or servicing equipment.

Qualified Personnel

Equipment owners are responsible for making sure that Nordson equipment is installed, operated, and serviced by qualified personnel. Qualified personnel are those employees or contractors who are trained to safely perform their assigned tasks. They are familiar with all relevant safety rules and regulations and are physically capable of performing their assigned tasks.

Intended Use

Use of Nordson equipment in ways other than those described in the documentation supplied with the equipment may result in injury to persons or damage to property.

Some examples of unintended use of equipment include

S

using incompatible materials

S

making unauthorized modifications

S

removing or bypassing safety guards or interlocks

S

using incompatible or damaged parts

S

using unapproved auxiliary equipment

S

operating equipment in excess of maximum ratings

(8)

Personal Safety

To prevent injury, follow these instructions.

S

Do not operate or service equipment unless you are qualified.

S

Do not operate equipment unless safety guards, doors, or covers are

intact and automatic interlocks are operating properly. Do not bypass or disarm any safety devices.

S

Keep clear of moving equipment. Before adjusting or servicing moving

equipment, shut off the power supply and wait until the equipment comes to a complete stop. Lock out power and secure the equipment to prevent unexpected movement.

S

Relieve (bleed off) hydraulic and pneumatic pressure before adjusting or servicing pressurized systems or components. Disconnect, lock out, and tag switches before servicing electrical equipment.

S

While operating manual spray guns, make sure you are grounded.

Wear electrically conductive gloves or a grounding strap connected to the gun handle or other true earth ground. Do not wear or carry metallic objects such as jewelry or tools.

S

If you receive even a slight electrical shock, shut down all electrical or electrostatic equipment immediately. Do not restart the equipment until the problem has been identified and corrected.

S

Obtain and read Safety Data Sheets (SDS) for all materials used. Follow the manufacturer’s instructions for safe handling and use of materials, and use recommended personal protection devices.

S

Make sure the spray area is adequately ventilated.

S

To prevent injury, be aware of less-obvious dangers in the workplace that often cannot be completely eliminated, such as hot surfaces, sharp edges, energized electrical circuits, and moving parts that cannot be enclosed or otherwise guarded for practical reasons.

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 SDS for the injected fluid to the health care provider.

(9)

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:

S

Go to an emergency room immediately.

S

Tell the doctor that you suspect an injection injury.

S

Show them this card

S

Tell them 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.

S

Ground 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.

S

Shut down all equipment immediately if you notice static sparking or arcing. Do not restart the equipment until the cause has been identified and corrected.

S

Do not smoke, weld, grind, or use open flames where flammable

materials are being used or stored.

(10)

Fire Safety

(contd)

S

Provide adequate ventilation to prevent dangerous concentrations of volatile particles or vapors. Refer to local codes or your material SDS for guidance.

S

Do not disconnect live electrical circuits when working with flammable materials. Shut off power at a disconnect switch first to prevent sparking.

S

Know 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.

S

Shut off electrostatic power and ground the charging system before adjusting, cleaning, or repairing electrostatic equipment.

S

Clean, maintain, test, and repair equipment according to the instructions in your equipment documentation.

S

Use 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 SDS 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:

S

Disconnect and lock out system electrical power. Close hydraulic and pneumatic shutoff valves and relieve pressures.

S

Identify the reason for the malfunction and correct it before restarting the system.

Pump Operation

Refer to Table 4-1 and see Figure 4-1.

Basic Operation

A container of adhesive or sealant material is centered between the

container locators/guides and under the follower plate. The ram consists of an air-driven piston that lowers the follower plate into the container of material. The elastomer seal(s) around the outer edge of the follower plate creates an airtight compartment below the follower plate. Downward movement of the follower plate forces material into the hydraulic section of the pump.

When the piston of the ram cylinder activates the magnetic sensor at the bottom of the ram cylinder, the controls will shut off air supply to the air motor, signaling that the material container is empty. Follow the Container

Change Procedure on page 4-5 to complete the container change

procedure.

Pneumatic Controls

The operating controls for the unloader are primarily pneumatic. Clean, dry shop air filtered to 5 microns (filter is supplied by the customer) is supplied to three/four pressure regulators (four for systems with ARW): one for the pump air motor, one for the ram down, and one for the ram up/blow-off. The ram up/blow-off pressure is a fixed pressure.

Air Motor Supply

The regulated air supply flows through a shut-off valve before it enters the pump air motor.

Unregulated air at full shop pressure is supplied to the pilot valve. This valve supplies pilot air to the main motor control valve. This

higher-pressure signal air enables the air motor to make rapid directional changes regardless of the regulated supply air setting.

(55)

Ram and Blow-Off Air Supply

The control module is primarily pneumatic. Shop air pressure is supplied to the control when the control module lockout valve is opened. Opening this lockout valve allows for operation of the ram direction control and the material container blow-off valve. Air pressure to the air motor regulator, as well as the signal valves in the control and air motor, are also activated. Air pressure is only supplied to the air motor when the air motor lockout valve is opened. The air supply to the pilot, intermediate, and material container blow-off valves is at full shop pressure.

The regulated air supply for the ram cylinder flows to a three-position elevator control valve. The valve controls the flow of air to the ram cylinder. The ram direction control has three positions: Ram Up, Ram Down,

and Neutral.

S

Ram Up position: Air enters the bottom of the cylinder. Air above the

elevator cylinder piston is vented. The air pressure forces the cylinder piston upward, which raises the follower plate and pump.

S

Ram Down position: Air enters the top of the cylinder. Air below the

elevator cylinder piston is vented. The air pressure forces the cylinder piston downward, which lowers the follower plate and pump.

S

Neutral position: There is no pressure to the elevator cylinder. The

follower plate should remain stationary, since the air pressure to both sides of the piston is sealed.

WARNING: The Neutral position is not a locked and secured position. The

follower plate may drift downward over time.

The blow-off feature routes air under the follower plate during the removal of an empty container. The blow-off nipple assembly connects to the follower bleed port. Putting the ram direction control in the Ram Up position while the follower is in the container and pressing and holding the purge button forces air under the follower plate. The air pressure forces the container off of the follower plate.

(56)

Maintenance

This section details the preventative maintenance procedures for the unloader. The frequencies listed are only guidelines. Always perform preventative maintenance procedures according to your facility maintenance schedule.

It may be necessary to adjust frequencies due to the facility environment, process parameters, material being applied, or experience.

WARNING: Never use halogenated hydrocarbon solvents to clean

aluminum parts or to flush any system. Cleaning agents, coatings and paints, or adhesives may contain halogenated hydrocarbon solvents. Obtain and read the SDS for each material and solvent being used.

WARNING: Always relieve system pressure before servicing equipment.

Trigger all dispensing devices and bleed off system pressure.
