WARNING

FIRE AND EXPLOSION HAZARD

Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and result in a fire or explosion and serious injury.

D Connect the electronic dispensing control to a grounded outlet. Ground the other equipment as

instructed in their separate instruction manuals.

D All electrical products must be wired by a qualified electrician.

D The control and all electrical products described in this manual must be installed in a non-hazard-

ous location.

D If there is any static sparking or you feel an electric shock while using this equipment, stop dis-

pensing immediately. Do not use the equipment until you identify and correct the problem.

D Keep liquids away from the electrical components.

D Disconnect electrical power at the main switch before servicing the equipment.

D Keep the dispense area free of debris, including solvent, rags, and gasoline.

D Do not smoke in the dispense area.

NOTE: The Electronic Dispensing Control is referred

to as the “control” in this manual.

How the Fluid Commander System Works

The operator programs the control by selecting a fluid and station and setting the quantity to dispense. When the operator presses the DISPENSE key, the control energizes the respective air and fluid solenoid valves. As the fluid is dispensed, the pulse meter sends pulses to the control in proportion to the amount of fluid flowing through it. When the number of pulses counted by the control is equivalent to the preset quantity, the air and fluid solenoid valves shut off. Refer to Opera-

tion for more detailed information on using the system. NOTE: The Typical Installation shown above is only a guide for a basic system, showing just one fluid. Call your Graco representative to design a system to suit your needs.

WARNING

COMPONENT RUPTURE HAZARD

A Pressure Relief Kit is required in your system to reduce the risk of serious injury,

which can occur if excessive pressure ruptures the lines and components. Install Kit 237893 as shown in Fig. 1. See page 18 for ordering information.

Installation

WARNING

COMPONENT RUPTURE HAZARD

Be sure that all accessories and system components can withstand the pres-

sures developed. The maximum fluid working pressure of the Fluid Commander System is 1500 psi (10.4 MPa, 103 bar). Never exceed the maximum working pressure of the lowest rated accessory (valve, pipe, fitting, hose, etc.) in your system.

NOTE: The accessories mentioned in this manual are shown on pages 16 and 17.

Mount the Control

Place the control on a desktop or mount it on a wall, and locate it at least 18 in. (441 mm) off the floor.

WARNING

FIRE, EXPLOSION, AND ELECTRIC

SHOCK HAZARD

To reduce the risk of fire or explosion,

and serious injury, including electric

shock:

The control and all electrical products

described in this manual must be

installed in a non-hazardous location.

CAUTION

If you do not use the recommended air and fluid valves, verify that the valves do not exceed 0.6 amp of supply current when operated with 24 Vdc.

Pages 7 and 8 show the alternative wiring schematic, using customer-supplied cables with Graco-supplied valves and pulsers.

Page 8 shows where the wires connect at the rear of the control, depending on the number of fluids you are using. Fig. 2, below, shows how to make the electrical connections at the control, using the supplied probe.

CAUTION

To ensure correct polarity of the electrical supply, use only the power supply cord supplied with the control. Any other power supply cord may permanently damage the control.

Apply Labels to the Control

Determine what fluids will be dispensed, and apply the appropriate labels within the raised area on the control, next to the station pads. See Fig. 3, page 11.

WIRE

Strip back 1/4” (6.35 mm) insulation

All electrical products must be wired by a qualified electrician, following all local, state, and national codes.

Connect the control only to a grounded outlet.

Connect the Electrical Wiring

Determine the wire gauge to use based on the length of the run:

Up to 200 ft (61 m): 18 AWG 201 to 500 ft (152 m): 16 AWG 501 to 1000 ft (305 m): 14 AWG

Page 6 shows the recommended wiring schematic, using Graco supplied cables, valves, and pulsers.
