Warnings

The following general warnings are related to the safe setup, use, grounding, maintenance, and repair of this equipment. Additional more specific warnings may be found throughout the text of this manual where applicable.

WARNING

FIRE AND EXPLOSION HAZARD

Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent fire and explosion:

• Use equipment only in well ventilated area.

• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop cloths (potential static arc).

• Keep work area free of debris, including solvent, rags and gasoline.

• Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes are present.

• Ground all equipment in work area. See Grounding instructions.

• Use only grounded hoses.

• Hold gun firmly to side of grounded pail when triggering into pail.

• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment until you identify and correct the problem.

• Keep a fire extinguisher in the work area.

PRESSURIZED EQUIPMENT HAZARD

Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin and cause serious injury.

• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.

• Tighten all fluid connections before operating the equipment.

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

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

• 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.

• Check equipment daily. Repair or replace worn or damaged parts immediately.

• Do not alter or modify equipment.

• For professional use only.

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

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

• Do not kink or overbend hoses or use hoses to pull equipment.

• Comply with all applicable safety regulations.

Warnings

WARNING

MOVING PARTS HAZARD

Moving parts can pinch or amputate fingers and other body parts.

• Keep clear of moving parts.

• Do not operate equipment with protective guards or covers removed.

• Pressurized equipment can start without warning. Before checking, moving, or servicing equipment,

follow the Pressure Relief Procedure in this manual. Disconnect power or air supply.

TOXIC FLUID OR FUMES HAZARD

Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swallowed.

• Read MSDS’s to know the specific hazards of the fluids you are using.

• Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.

PERSONAL PROTECTIVE EQUIPMENT

You must wear appropriate protective equipment when operating, servicing, or when in the operating area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic fumes, burns, and hearing loss. This equipment includes but is not limited to:

• Protective eyewear

• Clothing and respirator as recommended by the fluid and solvent manufacturer

•Gloves

• Hearing protection

Overview

Usage

The ProMix Easy can mix most two-component paints. It is not for use with “quick-setting” paints (those with a pot life of less than 5 minutes) without modification. Contact your distributor for information.

The ProMix Easy is operated with the User Interface, Air Controls and Fluid Controls, described below and on page 7. Refer to F

User Interface

The User Interface has 6 main interfaces.

1. Function Knob to select desired function:

Icon Function

IG. 1 and FIG. 3.

Spray: proportion and spray material.

Run A: operate A independent of B (prim-

ing, flushing) for 12 cycles. Run B: operate B independent of A (prim-

ing, flushing) for 12 cycles. Batch Dispense: dispense proportioned

amounts of A and B (1 pint/500 cc). Pump Test: dispense predetermined

amount of A and B to verify pump operation.

Recirculation: optional; requires 248652 Circulation Kit, see page 23.

Pot Life Timer: display potlife time left.

Pressure Relief/Park: allows pressure relief

and runs pumps to the bottom of stroke. See page 13.

3. Stop button to terminate functions.

4. Key switch to change ratio, pot life time, pot life vol-

ume, or calibration data.

5. Display (five digits) to view:

• Software revision level at startup

•Ratio

• Pot life time and reset volume

• Alarm codes

• Sensor calibration factor.

6. Data port allows for connection to a PC serial port

to download volume totalizer, operation, ratio setting, and error alarm data.

WARNING

To avoid impairing intrinsic safety and reduce the risk of fire and explosion, the PC must be in a non-hazardous location and a safety barrier must be installed between the PC and ProMix Easy unit. See data download kit manual 309623.

• System totalizers count in Spray and Batch Dispense functions only.

• A and B Indicators (LT) show which dispense valve(s) is open.

2. Start button to initiate functions.

IG. 1. User Interface

You must recalibrate the circuit board whenever the main circuit board, software, or sensor is replaced, or when Alarm 8 occurs. See Recalibrate System, page 25.

Air Controls

Overview

See FIG. 3.

• Bleed-type main air shutoff valve (C), shuts off all

air to ProMix Easy (including controller power).

• Supply air pressure gauge (D), monitors air pres-

sure to ProMix Easy.

A minimum air pressure supply of 70 psi (483 kPa,

4.8 bar) must be maintained for the ProMix Easy to operate properly.

• Pump air pressure regulator (E) with gauge (F),

adjusts and monitors pump air pressure.

• Gun air regulator (P) and gauge (shipped loose),

adjusts and monitors gun air pressure.

Solenoid Module

There are two solenoids inside the pneumatic control box, one to actuate dispense valve A, one to actuate dispense valve B.

FIG. 2. Dispense Valves, Sampling Valves, and Fluid Outlet Valves

TI4808a

Fluid Control Valves

• Dispense valves (DA, DB) dispense the correct

dose of component A and component B to the remote mix manifold. Solenoids A and B turn the dispense valves ON and OFF. See F

• Sampling valves (SA, SB), to batch dispense or

test pumps. See F

• Fluid outlet valves allow components A and B to

enter the fluid hoses. See F

Solvent Control Valves

Solvent pump (U) pumps solvent from a user-supplied solvent container.

• Solvent pump air valve (SV) turns on the solvent

pump.

• A and B solvent valves (VA, VB) allow flushing of

sampling valves A and B.

• Solvent valves allow flushing of the mix manifold, whip hose, and gun. Valve S1 is at the solvent pump outlet. Valve S2 is at the mix manifold.
