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 the
appropriate fluid and station and setting the quantity to
be dispensed. When the operator depresses DISPENSE key, the control energizes the respective air
and fluid solenoid valves. As the fluid is dispensed by
the service person, the pulse meter sends pulses to
the control in proportion to the amount 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 OPERATION for
more detailed information on using the system.

About the Typical Installation
The TYPICAL INSTALLATION is only a guide for a
basic system, showing just one fluid. Your Graco sales
representative can help you design a system to suit
your needs.
WARNING
A Pressure Relief Kit is required in your system
to reduce the risk of serious bodily injury such as
splashing fluid in the eyes or on the skin, which
can occur if excessive system pressure ruptures
the lines and components. Install the kit as
shown in the Typical Installation Drawing. Order
Graco Part No. 207–221. See page 7.
INSTALLATION
WARNING
Be sure that all accessory items and system components can withstand the pressures developed.
The maximum fluid working pressure of the Fluid
Commander System is 1500 psi (103 bar). NEVER exceed the maximum working pressure of the
lowest rated accessory (valve, pipe, fitting, hose,
etc.) in your system.
2. Connect the electrical wiring
The wire gauge to be used should be determined by
the length of the run:
18 AWG up to 500 ft. (152 m)
16 AWG up to 1000 ft. (305 m)
Page 4 shows the recommended wiring schematic
using Graco supplied cables, valves and pulsers.
CAUTION
NOTE: The accessories mentioned in this manual are
shown on pages 15 and 16.
1. 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
To reduce the risk of fire or explosion and serious
bodily injury including electric shock:
If you do not use the Graco recommended air and
fluid valves, verify that the valves DO NOT
exceed 1 amp of supply current when operated
with 24 V DC.
Page 5 shows the alternative wiring schematic using
customer-supplied cables with Graco-supplied valves
and pulsers.
Page 6 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
D The control and all electrical products
described in this manual must be installed in
a non–hazardous location.
D All electrical products must be wired by a qualified electrician, following all Local, State
and National codes.
D Connect only to a grounded outlet.
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.
3. Apply labels to the control
After determining the fluids to be dispensed, apply the
appropriate labels within the raised area next to the
station pads. See Fig 3, page 7.
WIRE
Strip back 1/4” insulation
PROBE
(supplied with control)
The probe functions much like a can opener.
Hook the bottom of the probe under the lip of
the terminal strip and raise the probe handle
so the top of the probe enters the slot and
presses down the connector. Install the wire
firmly and release the probe.

system.
NUT
OPERATOR
The solenoid valve is normally closed; foreign matter
could hold the valve open, preventing it from stopping
the fluid flow. If that happens, stop the pump, open the
dispensing valve controled by the solenoid valve to
relieve line pressure, and close the shutoff valve ahead
of the solenoid valve.
