Warnings

Warnings

The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.

WARNING

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

• Do not operate the unit when fatigued or under the influence of drugs or alcohol.

• Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See Technical Data in all equipment manuals.

• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information about your material, request MSDS from distributor or retailer.

• Do not leave the work area while equipment is energized or under pressure.

• Turn off all equipment and follow the Pressure Relief Procedure when equipment is not in use.

• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufacturer’s replacement parts only.

• Do not alter or modify equipment. Alterations or modifications may void agency approvals and create safety hazards.

• Make sure all equipment is rated and approved for the environment in which you are using it.

• Use equipment only for its intended purpose. Call your distributor for information.

• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.

• Do not kink or over bend hoses or use hoses to pull equipment.

• Keep children and animals away from work area.

• Comply with all applicable safety regulations.

SKIN INJECTION HAZARD

High-pressure fluid from dispensing device, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.

• Do not point dispensing device at anyone or at any part of the body.

• Do not put your hand over the fluid outlet.

• Do not stop or deflect leaks with your hand, body, glove, or rag.

• Follow the Pressure Relief Procedure when you stop dispensing and before cleaning, checking, or servicing equipment.

• Tighten all fluid connections before operating the equipment.

• Check hoses and couplings daily. Replace worn or damaged parts immediately.

Installation

Installation

These meters must be installed in-line as part of a dispense system as shown in Fig. The typical installation shown is only a guide for selecting and installing an in-line meter. It is not an actual system design. Contact your Graco representative for assistance in designing a system to suit your needs.

Operation

To Activate the Digital Display

Press the RESET key pad to clear the meter before starting a new dispense cycle. This is the best way to activate the meter, because it also clears the quantity of the last dispense cycle.

The digital display can also be activated by pressing the

TOTAL key pad or by running fluid through the meter.

NOTE: The digital display of the meter goes blank after approximately two minutes of non-use.

To Change the Measurement

Units

( Gallon/Quart/Pint meter only)

The meter is factory set to dispense in quarts. To change the measurement units, press and hold the

RESET key pad until the measurement unit on the right side of the digital display is flashing. Then press the

TOTAL key pad until the desired measurement u nit is

shown. Release both key pads. (F

To see the accumulated total of fluid dispensed through the meter, press and hold the TOTAL key pad. The accumulated total is shown in gallons for the gallon/quart/pint meter, and in liters for the liter meter. The meter can accumulate a running total of up to 19,999 gallons (or liters) dispensed before returning to zero.

Operation

To Verify the Accuracy of an

Electronic Meter

1.

Use a clean, calibrated container. If using a single container, be sure to clean it after each dispense.

2.

Have pump air pressure at the lowest possible setting for dispensing fluid.

3.

Put the tip of the nozzle at the bottom of the calibrated container.

4.

If the tip of the dispense valve does not reach the bottom of the calibrated container, use a length of plastic tubing over the tip of the nozzle to ensure liquid enters the container from the bottom.

5.

Trigger the gun slowly so the fluid immediately covers the tip of the dispense valve.

6.

Allow product to sit for 20 minutes, then compare the actual, physical measurement in the calibrated container to the measure displayed on the meter.

NOTE: The procedure above will determine if the meter is accurately dispensing the product and minimize testing errors. Some variance may occur depending on the viscosity of the fluid. If this procedure determines that the meter is not accurate, re-calibrate the meter as described in the service manual or replace the meter or the electronics as necessary.

For Maximum Dispensing

Accuracy

(gallon/quart/pint meter only)

Set the meter to dispense in pints or quarts when dispensing 1 gallon or less.

Always press the RESET key pad to clear the meter before a new dispense cycle.

Troubleshooting

Troubleshooting

NOTE: Before you check or repair the meter, be sure all other valves, controls, and the pump are operating properly.

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever you see this symbol.

This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure Relief

Procedure when you stop spraying and before cleaning, checking, or servicing the equipment.

1.

Turn off the power supply to the pump.

2.

Trigger the valve into a waste container to relieve pressure.

3.

Open any bleed-type master air valves and fluid drain valves in the system.

4.

Leave the drain valve open until you have completed repairs and are ready to pressurize the system.

Problem

Digital display does not activate.

There is no fluid flow.

Digital display is dim.

Cause Solution

Electronic control is malfunctioning.

Replace the electronic control.

For gallons/quarts/pins:

Order Part No. 235878

For Liters: Order Part No. 235901

Remove and clean strainer.

Strainer, if used is clogged.

Battery in electronic control is worn out.

Replace electronic control within approximately one week of when you notice dimness.

See part numbers above.

Repair

Repair

1.

Relieve the pressure. See Pressure Relief Proce-

dure, page 6.

2.

Attach the disposable grounding wrist strap to your wrist. Connect the adhesive-backed copper foil at the other end to any convenient electrical ground, such as the grounding screw or metal case of a grounded electrical outlet.

3.

Lift the bottom edge of the black cover (1) away from the meter (2), and pull the cover off. Remove and discard the screws (6). Lift off the electronic control

(3). Remove and discard the large o-ring (4).

4.

Install a new electronic control (3). Install the large o-ring (4) over the lip on the top of the metering unit

(2). Align the notch on the side of the electronic control (3) with the notch on the side of the metering unit (2). Install new screws (6). Tighten the screws

(6) to 3 in-lbs to 5 in-lbs (0.34 N.m to 0.57 N.m) oppositely and evenly until a complete seal is

obtained as shown in the DETAIL in F

IG

. 6.

5.

Install the cover so the rolled-in edges are parallel with the inlet fluid passage of the metering unit.
