The TYPICAL INSTALLATION
drawing shown on page
2 shows the various components
required in a typical
system and the order in which the components
should
be installed.
NOTE:
This instruction
manual gives instructions
for the installation and operation of the system, and service instructions
for the modules, solenoid valves and fluid
meters. See the ACCESSORIES
section on page 17 for
available
Grace components,
and the instruction
manuals that are provided with the purchase of these
components
for more detailed information
on their installation, operation and service.
Refer to the TYPICAL INSTALLATION
and install your
fluid supply plumbing.
Avoid unnecessary
turns and
where practical,
use long sweeping bends in tubing.
Buy tubing or pipe in long.lengths to reduce the number
of joints.
Make sure joints are accessible
- never
underground
or buried in concrete. Install shutoff valves
(PI at both ends of fluid lines. Remove burrs, clean dirt
and chips from ends of tubing, and ream iron pipe ends.
Proper installation is the key to the success of your MFC
System. The system will work perfectly the first time if it
is installed properly.
Blow out fluid lines with air. Do Not install fluid line
filters (Q) or connect lines to solenoid valve (RI until
after flushing lines with fluid.
TWO
ARE:
Install Fluid Meters and Flush Fluid Lines
Install the fluid meters (L) in the fluid line near the pump
outlet, using suitable adapters for the l/2 npt(f) inlet
and outlet of meter. Downstream
from the meter, install
a gate valve (N) to isolate the pump and meter for servicing, etc.
1.
VERY
IMPORTANT
THINGS
TO REMEMBER
All fluid lines must be absolutely clean and free of
any material which might clog solenoid valves or
fluid meters. Fluid line filters must be installed in
line to protect solenoid valve.
2 . The system must be wired properly. We recommend having a licensed electrician do the job. The
circuits must conform to local codes for Class 2 circuits, and the right connections
must be made for
the system
to work
properly.
Use only preconnected cable.
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 750 psi (52 bar). NEVER exceed the maximum working pressure of the lowest
rated accessory (valve, pipe, fitting, hose, etc.) in
your system.

Select locations for the dispensing stations and install
your dispensing equipment (S). Hose reels and dispensing bars are available.
Install Air Supply
Lines and Fluid Lines
Connect the plumbing for the air supply to pumps. Install a bleed-type,
master air valve (G) in an accessible
place for each pump for easy shut off.

307-362
If your pumps will supply more than 750 psi
(52 bar) fluid pressure with existing
air
pressure,
install
an air regulator
(HI
upstream from the air solenoid valve (J).
Lines and components
are subject to high pressures
when fluid in the line expands
due to a rise in
temperature.
For automatic
pressure relief if the fluid
pressures exceed 900 psi (62 bar), install the Pressure
Relief Kit (MI between the meter outlet and the pump
fluid intake.
Connect fluid hoses from pump to supply line with a
swivel union fitting.
Refer to the Typical Installation
drawing. Place the pump intakes in pails of a compatible
solvent. Start the pumps and thoroughly flush the lines.
NOTE:
If your
valve,
passed
on the
system includes a pump air solenoid
to start the pump it must either be byor wired to the PUMP SOL Position
junction strip (D). See page 7.
Close the shut off valve (PI at the supply line outlet and
leave the pump turned on. Check all connections
for
leaks. Stop the pump, close the master air valve (G),
and open the shutoff valves (PI to relieve line pressure.
Then tighten any leaking connections.

Wiring
Diagram
The wiring diagram in Fig 7 is just an example. Your
system may have any number of dispensing
modules
powered by a single Power Supply Module, and fluids
may be routed in any combination
required for your
system.
In this example, one Power Supply Module (C), one
dispensing module (for controlling
oil), and one dispensing module (for controlling
ATF) is used. The only difference between Modules A & B is the addition of a
batch counter on Module B.

last two positions of the corresponding
junction
NOTE:
Always connect all cables to one junction
strip before beginning on another strip.
For Module A, connect cables between corresponding
solenoids on OIL fluid line and station positions on junction strip for both Stations 1 and 2. Then connect cables
between corresponding
solenoids on ATF fluid line and
station positions on Module B junction strip for both
stations.
NOTE:
Wire each dispensing
station to junction
strip so the dispensing station number corresponds with STA SOL number on the
strip. For example,
station 1 connects
to
STA. 1 SOL positions, station 2 connects to
STA. 2 SOL positions, and so on.
Each dispensing module is connected by electrical cable
to its own junction strip (D). Each junction strip has
twelve station solenoid
connections
(CC), a pump
solenoid connection
(AA) and a fluid meter connection
(BB). All cables used in the MFC system are preconnetted cables, coupled oppositely,
that plug together

center attendant
If using Module B with batch counter (KK),
you must push the Dispense Button (FF) and
the Batch Reset Button (LL) at the same
time to activate system.
Short delivery may occur due to meter cam
being at mid-contact
point or air in fluid supply lines. Repeat dispensing 1 or 2 units until
metered amount is correct.
A Bypass Switch (NN), located at the back of a
Dispensing
Module,
allows you to use your
module even if the Counter becomes inoperative.
Select the station to which fluid is to be dispensed
and turn on the Bypass Switch. Fluid will continue
to be supplied as long as the station needs it, and
the Totalizer (JJ) will continue to tally the amount
dispensed.
If the operator has begun dispensing an order which
you think you have shorted, allow him to complete the
order, compare your last Totalizer entry in the log book
with the current Totalizer reading on module to determine amount of shortage. If your Dispensing Module
has a Batch Totalizer (LL), the reading on it will tell you
the exact amount dispensed.
If you have entered more on the Count Set Counter
(GG) than requested
and operator
has begun to
dispense.order,
allow him to take only what he needs.
(You can check amount being dispensed by comparing
Totalizer readings or the Batch Totalizer). Record order
in log book. Then select a quantity of 0.1 on counter,
push Dispense Button, and dispense this amount. This
will clear the fluid meter so you are ready to dispense
another order.
When operator requesting order sees his “ready”
light at Dispensing Station (S) come on, he opens
dispensing
valve and takes full amount ordered.
When full amount has been dispensed, “ready”
light will go out and fluid flow
will stop
automatically.

A Wrong Dispense
Order
Be sure to keep your log book updated with
each order. This will help you correct errors
if any are made.
If you select the wrong quantity or station, and have
pushed the Dispense Button (FF), the selection may be
cancelled
by turning
off Keyswitch

operator has not begun to dispense.
If another module is dispensing an order when you shut
the power off to correct an error, the order will continue
to dispense as soon as you turn it back on.
