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.

This instruction manual gives instructions for the in-

stallation and operation of the system, and service in-

structions 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 in-

stallation, operation and service.

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.

TWO VERY IMPORTANT THINGS TO REMEMBER

ARE:

1. 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 recom-

mend having a licensed electrician do the job. The

circuits must conform to local codes for Class 2 cir-

cuits, and the right connections must be made for

the system to

connected cable. work properly. Use only pre-

WARNING

Be sure that all accessory items and system com-

ponents can withstand the pressures developed.

The maximum fluid working pressure of the Fluid

Commander System is 750 psi (52 bar). NEVER ex-

ceed the maximum working pressure of the lowest

rated accessory (valve, pipe, fitting, hose, etc.) in

your system.

Install Dispensing Equipment and Pumps

Mount pumps where they will connect to the fluid tanks

but do not connect them yet. The pumps will be con-

nected to the tanks after the fluid lines are flushed.

Select locations for the dispensing stations and install

your dispensing equipment (S). Hose reels and dispens-

ing bars are available.

Install Air Supply Lines and Fluid Lines

Connect the plumbing for the air supply to pumps. In-

stall a bleed-type, master air valve (G) in an accessible

place for each pump for easy shut off.

NOTE: 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).

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.

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.

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 ser-

vicing, etc.

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 system includes a pump air solenoid

valve, to start the pump it must either be by-

passed or wired to the PUMP SOL Position

on the 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.

Remove pails of solvent and connect the pumps to the

fluid tanks.

Install Filters, Connect Solenoid Valve

And Fluid Lines

Install the fluid line filters (Q) in line to protect the

solenoid valves (RI from foreign material in supply lines.

Connect the solenoid valves and fluid supply lines to

dispensing equipment (S). See separate instruction

manuals for dispensing equipment and how to connect

solenoids.

Install and Wire Modular Fluid Commander

Have a licensed electrician wire the system according to

local codes for Class 2 circuits and the following instruc-

tions. Instructions for wiring a basic, typical system are

shown in Fig 7, page 7.

Select a location for your Modular Fluid Commander

where counters and totalizers are easily seen and con-

trols are within reach. The control modules (A,B,C) can

be wall-mounted.

Before mounting, connect the power terminals of

modules and fasten together with screws provided.

Fasten the right end panel (8) to the last dispensing

module. See Fig 2.

Mount the junction strips (D) on the wall, side by side.

Each junction strip has two holes in each end for l/4 in.

screws. See Fig 3.

Fig 3

Label Control Modules and Dispensing Stations

Label control modules (A,B) and dispensing stations (S)

using pressure sensitive labels provided in the instruc-

tion manual envelope. Above the counter (GG), place

QUART or LITER label, depending upon how you

measure your fluids. Label each module below the sta-

tion selector (HH) for the fluid it controls. Fig 4 shows

OIL and ATF labels. Label hose reels to correspond with

the modules that control fluid to each reel. Locate label

on each side of shroud at the bottom curved portion.

Place dispenser bar labels in space provided at the top

left of bar.

Install the electric cable, using only pre-connected elec-

trical cable (WI. Do not connect to junction strip yet.

We recommend marking each cable with the dispensing

module and station positon that it will connect to as the

wiring is completed.

NOTE:

Where lengths of cable are connected, form

loops and secure with a wire tie (XI or tape

to avoid strain on connections. See Fig 5.

Use a splice connector (Y) to connect pilot “ready”

lights of dispenser to solenoid valves (RI. Lay the lead

wire from the light and one of the lead wires from the

solenoid valve in the connector and fasten the connec-

tor. Then connect the remaining lead wire (Z) from the

solenoid valve to the wire that will connect that

dispenser to the corresponding connection on the junc-

tion strip. See Fig 6.

Wiring Diagram

The wiring diagram in Fig 7 is just an example. Your

system may have any number of dispensing modules

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 dispen-

sing module (for controlling ATF) is used. The only dif-

ference between Modules A & B is the addition of a

batch counter on Module B.

Only two stations are shown connected, but each

dispensing module is capable of controlling up to twelve

stations.

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 precon-

netted cables, coupled oppositely, that plug together

easily. The air solenoid valve (J) (optional, shown in this

diagram) and the fluid meter IL) are connected to the

last two positions of the corresponding junction strip.

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 junc-

tion 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 cor-

responds 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.

Pre-operating Checks

Before using your system, test electrical hookup and

purge fluid lines of air as follows:

1 . Open air valves (F B G) to pumps (K). Pumps will

prime themselves and stall against pressure. Plug

power supply cord into a grounded 120 volt, 60

Hz, AC service outlet.

operator has purged the lines, set Counter (GG) at

1 or 2. Push Dispense Button again and instruct

operator to hold valve open until “ready” light

goes out. Then check quantity dispensed.

Instruct operator at Dispensing Station (S) No. 1

to wait until the “ready” light at his station comes

on, then to hold valve open until line is purged of

air.

NOTE:

Short delivery may occur due to meter cam

being at mid-contact point or air in fluid sup-

ply lines. Repeat dispensing 1 or 2 units until

metered amount is correct.

Set Station Selector (HH) of Dispensing Module

A or B at number 1 and the Count Set Counter

(GG) at 10.0. Turn on power Keyswitch (DD). The

“power on” light (EE) on Power Supply Module

(Cl should glow. See Fig 8.

Push the Dispense Button (FF); “dispense” light

in button and “ready” light at station 1 should

glow. After “dispense” light goes out, indicating

How To Use Modular Fluid Commander System

NOTE:

Before starting to use your system for the

first time, record the Totalizer (JJ) readings

so you can tell how much fluid has been

dispensed from your tanks.

After receiving an order the control center attendant will

proceed as follows: (See Fig 8)

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 deter-

mine amount of shortage. If your Dispensing Module

has a Batch Totalizer (LL), the reading on it will tell you

the exact amount dispensed.

1. Turn power Keyswitch (DD) ON, set Selector

(HH) at station requesting order, set Counter (GG)

at number of quarts or liters wanted and push

Dispense Button (FF).

NOTE:

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.

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.

2. 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.

System Shutdown Procedure

For daily shutdown, turn power Keyswitch OFF and

remove key; key can only be removed in the OFF posi-

tion. Close pump air supply shutoff valves (F & G).

For weekend or long period shutdown:

3. When operator has taken his full order, Dispense 1.

Button light will go out. You must see that he Close pump air shutoff valves (F Et G). Set Station

Selector (HH) at station 1 and Counter (GG) at

takes full amount before filling another order. 10.0.

($;eECting 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.

2. Push Dispense Button (FF) and have operator at

Station 1 open his dispensing valve to relieve fluid

line pressure.

If you select the wrong quantity or station, and have

pushed the Dispense Button (FF), the selection may be

cancelled by turning off Keyswitch (DD) if station

operator has not begun to dispense.

3. Repeat steps 1 and 2 for stations 2 and 3, then

turn the power Keyswitch off and remove key.

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.

NOTE:

Before starting controlled dispensing after a

long shutdown, it will be necessary to

dispense 4 or 5 units at each station to be

sure count is correct.

5 . Repeat above procedure for each Dispensing Sta-

tion. If system does not function properly at each

setting refer to the Troubleshooting Chart, page

10, to determine cause.

6. 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.

To Inspect, Adjust Or Service Fluid Meter:

Remove cover and proceed as follows:

To inspect or replace cam wheel: pull up on cam to see

if it is loose - tighten both setscrews if loose. Inspect

cam for damage or wear. Loosen setscrews and remove

cam from shaft if damaged or worn. Install new cam on

shaft, then adjust micro-switch (see Fig 9) and install

cover.

NOTE:

The normally open micro-switch must close

each time its roller rides over cam wheel

lobes. A quart meter has 5 lobes and a liter

meter has 10 lobes. To find out if micro-

switch is faulty, or needs adjustment, see

below:

To check for a faulty micro-switch, push switch roller

arm in all the way and use an ohmmeter or other

suitable instrument on soldered terminals of switch to

see if switch is closed. If not closed, remove switch, in-

stall new switch and adjust.

To adjust micro-switch, loosen both cam wheel

setscrews; rotate cam until switch roller rests on top of

a lobe and use an ohmmeter or other suitable instru-

ment to see if switch is closed. If it is not closed, loosen

both switch mounting screws, move switch in until it

closes, rotate cam wheel until roller rests on cam be-

tween two lobes; and check with ohmmeter to see if

switch is open. Tighten mounting screws where switch

opens and closes properly and install cover.

NOTE:

Do not bend micro-switch roller arm. If

switch cannot be adjusted properly, replace

switch.

To clean meter fluid piston, proceed as follows: (See

Fig 10)

1. Stop pump, dispense fluid at a station supplied by

this pump to relieve line pressure, close gate valve

downstream of meter and disconnect electric

power from Power Supply Module.

2. Disconnect fluid hose from gate valve and meter,

and meter from pump.

3. Secure meter in a vise and screw cap out of meter

housing. Carefully remove o-ring packing, using a

small straight blade screwdriver. Then remove

piston and chamber assembly.

4. Insert screwdriver into notch of chamber, pry off

top and remove inner parts.

5. Clean all parts, including meter housing,

thoroughly in solvent and blow dry. Inspect all

parts for damage or wear. Especially check outer

surfaces of piston and inner surfaces of chamber

bottom for pitting or scoring, and replace these

parts, if necessary, with a complete meter

assembly.

NOTE:

Be careful not to damage cam wheel or

micro-switch, or get solvent in switch when

servicing fluid piston.

6. To assemble, insert piston into chamber bottom

the divider plate is centered in slot of piston.

Turn the pawl pinion on gear box so the notch in

small disk on opposite side of gear box is centered

on the groove in the larger disk. Align the divider

plate in chamber bottom with groove in bottom of

gear box and snap together.

Care Of Fluid Solenoid Valves

The solenoid valve is normally closed; foreign matter

could hold valve open, preventing it from stopping fluid

flow.

Before attempting to service the solenoid valve, stop

pump and open dispensing valve controlled by solenoid

valve to relieve pressure in line, and shut off valve ahead

of solenoid.

To clean solenoid valve; unscrew operator retaining

nut, remove operator and pull piston from body; clean

parts and seat in body and blow air into body to clear

fluid passageways. See Fig 11.

Put parts back into body and dispense fluid to see if held

open conditiQn has been corrected - if not, replace

solenoid valve.

NOTE:

Dispense fluid at dispensing valve controlled

by solenoid valve cleaned or replaced until all

air is purged from system.
