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 the Safety Data Sheet (SDS) or contact your material supplier for more information. If you must use
halogenated hydrocarbon solvents, contact your EFD representative for compatible EFD components.

High Pressure Fluids

High pressure fluids, unless they are safely contained, are extremely hazardous. Always release 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.

WARNING

Any injury caused by high pressure liquid can be serious. If you are injured or even suspect an injury:

• Go to an emergency room immediately.

• Tell the doctor that you suspect an injection injury.

• Show the doctor the following note.

• Tell the doctor what kind of material you were dispensing.

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.

Initial Setup for Testing

Connect Power

1. Connect the power cord to the back of the dispenser.

2. Plug the power cord into your local power source.

3. Turn the power switch on the front panel to the on position.

Connect Foot Pedal

The UltimusV can be operated using the foot pedal provided, or by an external device
via a DB-15 connector.

1. Plug the foot pedal into the connector on the back of the dispenser.

2. You can also operate the UltimusV with an optional finger switch or a 5 to 24

VDC pulse.

Connect Air Input

NOTE: Clean, dry, filtered factory air is required to meet warranty. To ensure air

quality, install the five-micron filter regulator provided with the UltimusV.

1. Push one end of the air input hose into the Air In fitting on the back of the

dispenser.

2. Connect the other end of the air input hose to the filter regulator supplied

with the UltimusV dispenser.

NOTE: Input air should be set at least 1.0 bar (15 psi) — or more — higher
than dispensing pressure, up to a maximum of 0–7.0 bar (0–100 psi).

Connect Air Output

Push the connector on the adapter / Optimeter into the connector on the front of the
UltimusV and twist clockwise to lock.

Ultimus V High Precision Fluid Dispenser

Dispensing System Setup

Deposit size is controlled by time, pressure and tip size.
Please follow these instructions to test each function. Use the convenient Dot Standards sheet

included in your dispensing kit.

Using Steady Mode to Dispense a Dot or Stripe or Fill a Cavity

1. Start with pressure set to zero.

2. Place the syringe barrel over a piece of paper or test surface.

3. Place the unit in “Steady” mode.

4. Unsnap the safety clip. Depress and hold the foot pedal for the remainder of setup.

5. While resting the tip on the paper (test surface), increase the air pressure by 0.069–0.138 bar

(1–2 psi) using the keypad until you have reached the desired fluid dispensing flow rate.

NOTE: Always use the lowest possible pressure and the largest possible tip size. The
combination of the lowest possible output pressure + largest possible tip size + longest
possible dispense duration = most consistent and accurate deposits.

6. Release the foot pedal.

7. Retest the dispensing rate a few more times. Fine tune as required by making small changes

in pressure.

Remember — always
bring the tip in contact
with the work surface
at the illustrated angle.
After the tip is in
position, press the foot
pedal. Release pedal
and remove tip by
lifting straight up.

Correct angle
for consistent
deposits.

Ultimus V High Precision Fluid Dispenser

Using Timed Mode to Make Repeatable Deposits

1. Refer to the previous section to purge your dispense tip of air and fill it with fluid.

2. Place the unit into “Timed” mode.

3. Set the dispense time. The dispense time or duration may be set in one of two ways:

• Using the Up / down Arrows to set time. Refer to the “Features and Controls” section.

• Using the Program / Teach button to set time. Refer to the “Features and Controls” section.

4. Press the foot pedal / finger switch to activate the dispense cycle. The dispenser will now continuously

dispense for the pre-set duration of time. Once the time has expired, the dispenser will stop dispensing and
await another triggering signal from the foot pedal / finger switch or signal from the host controller.

NOTE: The foot pedal / finger switch only needs to be pressed for a moment.
If the foot pedal / finger switch or contact closure I/O signal is initiated at any time during the dispense cycle,

the dispenser will immediately abort and stop dispensing. This is a unique safety feature to prevent accidental
dispensing.

Using the Vacuum Control Feature for Low Viscosity Fluids

The Vacuum Control feature allows you to dispense low viscosity fluids consistently without dripping between
cycles. The vacuum overcomes head pressure on the fluid within the barrel, which prevents dripping.

1. Make sure that you have attached an EFD syringe barrel filled with the

fluid intended for dispensing, and that the air pressure is set all the way to
zero. EFD recommends the use of a Blue LV Barrier piston for watery, low
viscosity materials.

2. Make sure the barrel adapter safety clip is closed.

LV Barrier

Air gap

3. Remove the tip cap and replace it with an appropriate EFD dispense tip.

4. Set the air pressure at 0.1 bar (2 psi).

1/2 maximum fill

5. While pointing the tip over a container or resting it on a test surface, release

the safety clip on the adapter / Optimeter hose assembly.

6. Place the dispenser in “Steady” mode. Depress and hold the foot pedal

until a drip begins to form at the end of the tip.

7. Release the foot pedal. At this point, fluid will continue to exit the tip.

8. Increase the vacuum using the keypad by 0.5 to 1.0 inches of water until

the fluid deposit size stabilizes without growing.

NOTE: Do not increase the vacuum to the point where the deposit is
actually drawn back into the tip or to where bubbles form in the barrel. Excessive vacuum causes inconsistent
dispensing.

9. Lift the tip off the test surface, wipe the tip end and retest by pressing the foot pedal momentarily. The deposit

should stay at the intended size and not increase or decrease in size. If it does, repeat steps 4–8 to fine-tune
the vacuum control.

10. Once the vacuum is properly set, increase air pressure to the desired production setting before beginning your

dispensing process.
