How the Fluid Commander system works
About the -pica1
The operator programs the control unit by selecting the
appropriate fluid and station and then setting the quantity
to be dispensed. When the DISPENSEkey Is depressed
by the operator, the Control unit energlzes the respective
air and fluid solenoid valves. As the fluid is dispensed by
the service person, the pulse unit sends pulses to the control unit in proportion to the amount flowing through it.
When the number of pulses counted by the control unit is
equivalent to the preset quantity, the air and fluid solenoid
valves shut off. Refer to OPERATIONfor more detailed information on using the system.
The TYPICAL INSTALLATIONis only a guideline for a basic system, showing just one fluid. Your Grace sales representative can help you design a system to suit your
needs.

Installation
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 Grace apartNo.
207-221. See page 7.
INSTALLATION
ponents can withstand the pressures developed.
The maximum fluid working pressure of the Fluid
Commander System is 756 psi (52 bar). NEVER exceed the maximum working pressure of the lOWeSt
rated accessory (valve, pipe, fitting, hose, etc.) in
Mount the Fluid Commander
The Fluid Commander can be placed on a desktop or
mounted on a wall using the accessory wail bracket, pan
no. 186-472. See Fig 1.
WARNING
To reduce the risk of serious bodily Injury Including
electric shock, the Fluid Commander must be installed and wired by a qualified electrician, following all local, State and National codes.
Electrical wiring
Have a qualified electrician install and wire the system.
Use 16 AWG wire for the entire system, up to 360 feet. For
longer lengths, contact Grace Technical Assistance.
Fig 3 on page 4 shows where the wires connect at the rear
of the control, depending on the number of fluids you are
using.
Fig 2 shows how to make the electrical connections.
proti underthe lip of the terminal
strip and raisethe probe handleso
the top of the probe entersthe slot
and presses down the connector.
Installthe wire firmly and release
the probe.
CAUTION
To ensure correct polarity of the electrical supply,
use only GRACO power supply cord 11l-262. Any
other power supply cord may permanently damage
MAINTENANCE
Apply labels to control
After determining the fluids to be served by each control,
apply the appropriate labels within the raised area next to
the station pads. See Flg 4, page 5.
To clean the control
Spray mild household cleaner (only) on a soft cloth and
wipe the unit clean. Do not allowthe cleaner or any other
fluid to seep under the front panel.
This control Is not user-repairable. If it Is not working
properly, return It to your Grace distributor for repair. DO
NOT open the control or attempt to make any repairs
yourself.
WARNING
To reduce the risk of electric shock, turn off the control and disconnect the power supply cord from the
outlet before checking for loose or shorted wires,
and before servicing the meters, or solenoid valves.

OPERATION
1. Program the security code and set the units
of measurement
5. To stop the dispense and check the Preset
amount
A four digit security code is required to activate the ContrOl
afler turning It on. Thls prevents unauthorized use of the
system.
Press STOP/CLEARand then press and hold AMOUNT
PRESETto verlfy the original order. Press DISPENSEto
continue the order.
me control is factory-set to dispense In quarts. Refer to
the instructions on the last page of this manual to change
the units of measurement, if necessary. Tear out the page
and keep it in a secure place.
6.
2.
Activate the control
Turn on the switch at rear of the control. The control does
a quick self-check and then the display shows fOUr
dashes. Enter your security code.
3.
Enter the order
Press the statlon number key for the appropriate fluid. The
light on the key will come on.
Press the white keys flrmly to enter the amount. For exam
ple;to enter 25.4 units, press the 10 twice, the 1 five times
and the 0.1 four times. If you make a mistake, press
STOP/CLEARand enter the total amount again.
NOTE: Holding in an amount key will cause the digit to
change continually until the key is released.
Press DISPENSE.The digital display shows all zeros and
the DISPENSElight blinks. As the order is dlspensed, the
display counts up and the fluid to the reel is shut off when
the preset amount is delivered.
4.
To checkthe preset amount during dispense
Press and hold AMOUNTPRESET.The order continues t0
be delivered unless you stop or clear It.
TO stop or clear an order
Press STOP/CLEARtwice to cancel and clear the order.
NOTE: This control delivers just one fluid to one station
at a time. During delivery, all pads on the control
are inac’tivated except AMOUNT PRESET and
STOP/CLEAR.
7.
TO find the total units delivered for each fluid
Press any station key for one fluid. Press and holdTOTAL
to read the amount. Repeat for the other fluids.
6.
If power is cut off
Each control has a built-in backup battery for its memory.
When power Is restored, reactivate the control by entering
the security code. The total amounts dispensed will still
be in the memory. If power was cut off during a dispense
cycle, the control will show the fluid, station and amount
already dispensed. Just press DISPENSEto continue.
The ON/OFF switch is also a 1.OAmp circuit breaker. If the
system shuts off unexpectedly, switch It off and on again.
If the problem continues, first determine if it is caused by
problems with the hard wiring. If the problem seems to be
with the control, return it to Grace for repair.
NOTE: Tnis control m

The solenoid valve is normally closed; foreign matter
could hold the valve open, preventing tt from stopping the fluid flow. If that happens, stop the,pump,
open the dispensing valve controlled by the solenoid
valve to relieve line pressure, and close the shutoff
valve ahead of the solenoid valve.
NUT
To clean the solenoid valve, unscrewthe nut, remove
the operator and unscrew the piston from the body.
Clean the pans and the seat In the body. Blow alr into
the body to clear the fluid passageways.
