GETTING STARTED, READ THIS PAGE.

THE NEXT 13 PAGES OF THIS MANUAL WILL GUIDE YOU, STEP BY STEP, TO A
SUCCESSFUL STARTUP.

IT WON'T TAKE LONG; SO.... PLEASE, DON'T SKIP AHEAD.

HERE ARE THE STEPS YOU WILL FOLLOW.

SAFETY HAZARDS: TWO HAZARDS exist on this unit: MIX BLADES and
Page 4 SLIDE VALVES. Read this short sensible page
so no one gets hurt.

ASSEMBLY INSTRUCTIONS: Very little assembly is required. But you
Page 6 might as well get it right the first time.
ALSO: Pay attention to the section on WIRING.

CHECK OUT PROCEDURE: This is to see if you did it right. It also
Page 11 will tell if anything was damaged in shipping.

LOAD CELL CALIBRATION: We already did this. But shipping or rough
Page 15 handling during assembly sometimes creates
load cell problems. If weight readings are not
correct, you MUST recalibrate the load cells.

TURNING ON OUTPUTS and
SETTING MATERIAL TYPES: To "TURN ON" a component, it must be
Page 16 designated as to TYPE, either REGRIND,
NATURAL, or ADDITIVE. Each is handled
differently by the MATH routines. The
controller MUST know the material TYPE to know
what the setting means. This is IMPORTANT. Be
SURE you UNDERSTAND this section before trying
to operate your system.

RATE CALIBRATION: This is NOT really necessary. But if your
Page 19 system uses non-standard equipment, you MAY
want to do this.

SETTINGS and NORMAL OPERATION:
Page 20 From this point forward, operating your system
is a snap. This section tells you just how
simple it is and exactly what to expect under
normal operating conditions.

SPECIAL FEATURES: Your system can do much more then you may
Page 23 know. This page reviews briefly some of the
added features that are available to you and
where in this manual you can find them.

ASSEMBLY and INSTALLATION INSTRUCTIONS

CAUTION: LOAD CELLS ARE EASILY DAMAGED.
If the FRAME is dropped from TWO FEET, the load cells WILL BE DAMAGED.
THE WARRANTY DOES NOT COVER DAMAGED LOAD CELLS.

The following items have been shipped to you:

1. FRAME and HOPPER assembly: (bolted to skid)

2. CONTROLLER BOX: with the instruction manual.

3. FEEDER BOX: contains a COLOR or ADDITIVE feeder: optional.

4. FLOW CONTROL ASSEMBLY: optional

5. FLOOR STAND or VACUUM TAKEOFF ASSEMBLY: optional

RED INSTRUCTION STICKERS will assist you during assembly.

LIFT HANGERS are available to allow lifting the blender with a strap or
chain. Call us if you require them.

1A. If your unit is to be MACHINE mounted:
For GB/WSB GBM, 100, 200, and 400 series models:
Two ways to do this are suggested ON THE NEXT PAGE: (4a)

The LEFT diagram shows the FRAME and SLIDE GATE both drilled
with the proper bolt pattern for your machine and THROUGH­ BOLTED to your press.

The RIGHT diagram shows only the 10 x 10 steel slide-gate plate
drilled for your bolt pattern and bolted to your press. The
FRAME is then bolted to it using the existing 8 x 8 inch bolt
pattern holes and bolts provided. With this method, bolt head
clearance holes are required in the poly-pro slide gate plate.
This mounting works well on smaller machines.

For GB/WSB 900 and 1800 series models:
An additional machine mount adaptor plate may be required. If
you have ANY DOUBT about the STABILITY of the unit when bolted
directly to your machine throat, please call us for advice.

NOTE: When choosing proper orientation, be sure to retain access to
the controller and weigh chamber, clearance for hinged doors,
and access to removable feeder hoppers.

1B. If your unit is STAND mounted:
A stand is provided and your unit will bolt directly to it. An
assembly DIAGRAM is provided on the following pages.

An air operated FLOW CONTROL ASSEMBLY is provided for dispensing
into a container. The purpose of this unit is to allow time for
mixing to occur after each dispense. This flow valve keeps the mix
chamber full to just below the sensor. This assembly bolts
directly to the bottom of the Blender frame.

Page 6

2. Slide the WEIGH BIN into position. It rests behind the clear
hinged access window. Install with the air cylinder toward you.
If bin is already in place, remove any shipping materials, packing
tape or string.

3. Hang the Color and Additive Feeders:

a. Lift side latches and fully extend slide assembly. Remove the
hopper. Leave slide extended.

b. Tilting the entire slide assembly, motor end up, insert one
corner of hanger cross bar behind frame corner post.

c. Rotate assembly into place so both ends of cross bar are behind
corner posts.

d. Lower into place, bottom edge resting on frame and cross bar
properly positioned behind corner posts.

e. Re-install hopper. Slide motor forward until latches engage.

4. Place the controller on the support tray and plug in all cords:

a. Air solenoid 8 or 14 pin plug into the matching receptacle.
b. Auger feeder drive motors into duplex receptacle.
c. Mixer motor into right side of controller.
d. Sensor cord plug into right side of controller.
e. Load Cell plug into port on left side of controller.

5. Plug the CONTROLLER into the receptacle located under the
controller tray.

IMPORTANT: Do NOT plug the controller into a separate power
source. The controller ground path MUST be the same as
the blender frame ground path. If your system has the
controller located in a remote location, MAKE CERTAIN
that the power to the controller comes from the
receptacle mounted on the Blender frame.

6. Plug the power cord coming from this box into a 110 volt power
source (220 volt outside U.S.). This cord MUST provide the ONLY
power source for the entire system, including the controller.
See: WIRING CONSIDERATIONS, next page. 1800 series blenders also
require a 240 volt power source for the mix motors.

7. Connect air pressure to the unit. About 80 psi (5.5 bar) is
recommended (40 psi for the Micro Blender). Lubricated air is NOT
recommended.

NOTE: GBM Micro Blenders should be set to 40 psi (2.7 bar).
The Vertical Valves used in removable hoppers on Micro
Blenders, 100, and 200 series blenders are more accurate at
the lower 40 psi pressure setting.

8. Remove all protective paper from the plastic windows.

Page 9

WIRING CONSIDERATIONS

The wiring of your blender is very important to its proper operation.
Electronics are very susceptible to voltage spikes and static charges,
both of which are very common in plastics factories.

To MINIMIZE these things, consider the following.

1. The power supply should be solid; a strong supply, not limited by a
"just adequate" control transformer. A source of voltage that
comes from a large transformer that supplies a large portion of the
plant is better then a small power supply transformer that is
intended to supply only this device. Power supplies, even though
they may be "isolation" transformers, will still pass all voltage
spikes right through. Their small size limits their ability to
dampen RF (Radio Frequency) noise that is often induced into the
system from outside sources. This proves worse then connection to
larger central transformers.

2. Avoid running the power supply line along side any heavy power
lines. An unshielded power supply in a raceway along side other
heavy power lines will pick up induced RF noise and transfer it
into the GB/WSB steel enclosure causing computer trouble.

3. Long extension cords should be avoided. They also reduce the
ability to provide a dampening effect on spikes and static. The
further the equipment is from a substantial power source, the more
susceptible it is to spikes.

4. The CONTROLLER and the GB/WSB frame MUST share the same GROUND PATH.
This is why you MUST plug the controller into the OUTLET that is
provided ON THE FRAME.

5. REMOTE SYSTEMS. If you have your controller mounted in a remote
location, you will have a number of power and signal cords running
between the frame and the controller. BE SURE that the LOW VOLTAGE
lines are NOT BUNDLED to the HIGH VOLTAGE lines and keep them away
from other nearby electrical lines.

LOW VOLTAGE lines are: Load Cell cable, Level Sensor cord, Air
Solenoid cable, and Printer and Computer cables.
HIGH VOLTAGE lines are: Mixer motor cable, Feeder motors, and MAIN
POWER line.
Keep these sets of cables SEPARATED.

6. VACUUM LOADER CONVEYING LINES. Keep them away from all electrical
lines, particularly the Load Cell lines. Conveying plastic
produces extreme static sources. A power supply line, even in
conduit, that runs next to a vacuum line, can introduce extreme
static pulses into the processor. Keep conveying lines SEPARATED
from electrical supply lines.

7. We use many internal tooth "STAR" washers in assembling the GB/WSB to
ensure good ground between painted parts. Do not remove them.

CHECK OUT PROCEDURE

As you go through this procedure, if WHAT SHOULD HAPPEN, doesn't
happen, see next section, DIAGNOSTICS, for what to check.

NOTE: 100/200 series models (3K load cells), display all weights in
1/10 grams ( x.x). 400/900/1800 series models (10K load
cells) display weights in FULL grams, NO decimal point. On this
page we show all weights with NO decimal point.

Start with NO MATERIAL in any hoppers.
Be sure an AIR SUPPLY is connected.
Place ALL switches DOWN; POWER (on front); STOP and PAUSE (on left).

PROCEDURE: WHAT SHOULD HAPPEN: .

PLUG IN CONTROLLER. Nothing should happen.
Air pressure should be holding ALL valves CLOSED.
This means all air cylinders are extended. If any
slide gate or flap is open, air lines are
reversed. If a FLOW CONTROL valve is installed,
check it.

TURN POWER ON. Display should say ( TWELVE ),
followed by version date (V=xxxxxT),
followed by the check sum number (CKS=xxxx),
followed by (ROM OK ),
followed by (RAM = 8K),
followed by model number (MODEL220) or the model
you have (GBM, 140, 14R, 220, 240, 24R, 420, 440,
44R, 940, 184),
followed by ( 0), then the actual weight of
material in the bin. This number should be zero,
plus or minus several grams ( 20) to (-20).

AT THIS POINT: Be sure the model number that was displayed
matches your blender model number (first digit
only). If this is not the case see two sections
ahead, SELECTING CORRECT MODEL.

TOUCH WEIGH BIN VERY LIGHTLY.
Display should update the weight every second
reflecting the light pressure that you are
exerting on the bin.

PRESS "*" KEY Display will say (PASSWORD)

REPEAT THIS SEQUENCE for each dispense valve on your WEIGH SCALE
BLENDER. Up to 12 outputs are possible numbered 1
through 9, A, B, and C. Only those connected to
devices will operate.

AT THIS POINT: NOTE which component NUMBER is assigned to each
hopper. You will want to know each hopper's
correct component number.

FACING THE CONTROLLER SIDE OF THE BLENDER:

On 9000 and 18000 gram, FOUR hopper compartment systems:
Device 1 is the NEAR hopper, 2 the FAR hopper, 3 the LEFT CENTER,
and 4 the RIGHT CENTER hopper.

On 1000, 2000, and 4000 gram, FOUR hopper systems, devices 1, 2, 3,
and 4 are counter-clockwise starting with far left corner hopper.

On 9000 and 18000 gram SIX hopper systems, devices 1, 2, 3, 4, 7, and
8 are counter-clockwise starting with far left corner hopper.

ALL MODELS:
Device 5 is the LEFT Panel-front OUTLET.
Device 6 is the RIGHT Panel-front OUTLET.

PRESS "DUMP" KEY The weigh bin air solenoid will operate.
LED # 13 will light.
The weigh bin dump valve will open.
Press "DUMP" repeatedly to observe operation.

PRESS "MIX" KEY This key controls the mix motor outlet on the
side of the controller. The mixer motor will run.

DIAGNOSTICS - for the CHECK OUT PROCEDURE

If display fails to come on at all:
check for power at outlet.
Check the 1/2 amp panel front fuse.

If first display says ( FOUR ), then this is NOT the correct manual
for this software. Obtain and use a FOUR software manual.

Possible model numbers are:
GBM, 140, 14R, 220, 240, 24R, 420, 440, 44R, 940, 184.
If model number is not correct for you unit:
see the next page, SELECTING CORRECT MODEL.

If display shows randomly drifting numbers:
check to see load cells are plugged in.

If display shows about (- 1250.0) or ( -4500):
check that the weigh bin is in place properly.

If display is steady but not near zero:
An over stressed load cell will display a permanently high
or low reading. Recalibrate load cells; next section.

If there is no response from the display when the bin is touched:
check for damaged wires to load cells.
check that load cell plug screws are secure.

If response is not sensitive or does not return to its start point:
check for interference around weigh bin.

If pressing * does not display (PASSWORD):
you are not in the normal power-up mode or the keypad
doesn't work. Normal mode is indicated by the ABSENCE of
the letter M or P at the left of the display.

If display says INVALID after entering the password number:
you pressed the wrong keys or the password number has been
changed and it is no longer 22222. Call us for help.

If an air solenoid does not operate:
check the 1/2 amp fuse.
check solenoid cable connected properly and fully seated.
check mix chamber door closed, safety interlock engaged.

If a slide or dump valve does not open:
check the air supply and regulator adjustment:
(minimum 20 psi, 80 psi (5.5 bar) recommended).
check for proper air line connection to cylinder.

If an auger feeder motor does not run:
check the 3 amp fuse.
check that the motor is plugged into the proper outlet.
check for faulty motor by plugging it into a known source of
110 volt A.C. power (240 volt outside U.S.).

SELECTING CORRECT MODEL

Controllers are programmed to control all sizes of Autoweigh Blenders.
The MODEL number that your unit is set for will be displayed during the
start up sequence every time power is turned on.

The possible models are:

MODEL BATCH WT valves WEIGH BIN LOAD CELL
(GRAMS) DIMENSIONS RATING

GBM 400 4 5 x 5 x 5 high 1 @ 3 K
140/14R 1000 4 10 x 6 x 6 high 1 @ 3 K

184 18000 4 16 x 16 x 17 high 2 @ 20 K
("R" models have 2 removable hoppers)

The addition of feeders will change the last digit of the model number.
This digit can be ignored for selecting the correct Model.

400, 1000 and 2000 gram systems with 3 kg. load cells; weights are
displayed in tenths of grams ( xxxx.x).

4000, 9000, and 18000 gram systems with 10 or 20 kg. load cells;
weights are displayed in full grams ( xxxxx).

If your unit is NOT set correctly to match the hardware you have, you
must change it. To do so:

Turn power on. From the NORMAL mode:

+-------------------------------------------------------+
¦ Press: * Display will say: (PASSWORD) ¦
¦ ¦
¦ Press: 97531 Display will say: (MODEL220) ¦
¦ or whatever model it is ¦
¦ currently set for. ¦
¦ ¦
¦ Press: * To walk through all model sizes. ¦
¦ When the model you want is displayed,¦
¦ then: ¦
¦ ¦
¦ Press: EXIT Wait a few seconds. ¦
¦ Unit will reset and restart ¦
¦ as the system you have selected. ¦
+-------------------------------------------------------+

When switching models, all parameter table information is lost and the
new "default" information for this model is loaded from ROM.

Page 14

+--------------------------------------------------------------------+
¦ PART II - OPERATION ¦
+--------------------------------------------------------------------+

LOAD CELL CALIBRATION

NOTE: Displays shown here are in full grams. 100 and 200 series
models are in 1/10 grams, with a decimal.

If your load cells already display a weight close to zero, plus or
minus 10 grams, you may skip this section and go directly to:

TURNING ON OUTPUTS (next page).

If your unit DOES NOT display an acceptable weight, you should
recalibrate them, that is reset your ZERO weight, at this time.

To do so:

BE SURE the weigh bin is EMPTY.
BE SURE the load cell plug is plugged into the side of the controller.
BE SURE the weigh bin is resting on the load cells freely.
BE SURE the air line to the dump valve is connected as it would be
during normal operation. A disconnected air line adds weight.
BE SURE The load cells and bin are not jammed in any way. To test for
this see that a light touch on the bin causes the display to
change. When the pressure is removed the display must return
to exactly where it was, plus or minus 1 gram.

If this does not happen, something is touching something and
the bin is not entirely free to move. Check EVERYTHING around
the bin.

LOAD CELL CALIBRATION:
The sequence of keystrokes is as follows:

Press: * Display will say: (PASSWORD)
Press: 22222 Display will say: (P x)
Press: *99 Display will say: (CAL OFF)
Press: * Display will say: (CAL ON )
Press: EXIT Display will say: (P x)
Press: ZERO Display will say: (--WAIT--)
followed by: (P 0)
Press: EXIT Display will say: ( x)

The ZERO point of the load cells is now set properly. FULL weight
calibration may also be done at this time, however, it probably is NOT
NECESSARY. When load cell readings shift due to rough handling, the
entire range of readings from ZERO to FULL shift together. The ZERO
weight calibration routine resets the full range of the cells and,
therefore, corrects FULL weight readings as well. For information on
FULL weight calibration, see RECALIBRATION OF LOAD CELLS.

¦ PROCEED TO: TURNING ON OUTPUTS ¦
¦ and MATERIAL TYPES NEXT PAGE ¦
+---------------------------------------------------+

Page 15

TURNING ON OUTPUTS - MATERIAL TYPES

This controller can control up to TWELVE (12) components; 1 through 9
and A, B, and C.

You must "TURN ON" the COMPONENT outputs that you are going to use.

Components that are TURNED OFF are not part of ANY routines.
A component becomes TURNED ON when it is set to a MATERIAL TYPE.

Material TYPES are REGRIND, NATURAL, and ADDITIVE.

The AUTOWEIGH BLENDER handles each TYPE DIFFERENTLY. Settings have
different meanings for each TYPE.

To enter SETTINGS correctly, you MUST UNDERSTAND how different
materials are handled based on their TYPE.

So PLEASE read this page CAREFULLY.

Material TYPES are explained here.
How to set them is explained on the next page.

REGRIND (PERCENT OF MIX)

Components designated REGRIND will be added as a PERCENT of the ENTIRE
MIX of material. For example, If component 1 is designated as REGRIND
and is set for 20.0 percent, then for every 100 pounds of blend, 20
pounds will be this component.

NATURAL (RATIO TO EACH OTHER)

Components designated NATURAL will be added in the proportion that you
specify them to each other. Their actual percentage of the mix will
depend on how much Regrind is specified and how much Additive is
specified. For example, if components 2 and 3 are both designated
NATURAL and are set for 10 and 40 respectively, then the RATIO of
component 2 to component 3 will always be 10 to 40 or 1 to 4.

If no Regrind or Additives are specified, the mix will be:
component 2, NATURAL, SET= 10, 20.0 percent of mix,
component 3, NATURAL, SET= 40, 80.0 percent of mix.

The RATIO of 1 to 4 is maintained.

If component 1 is specified as REGRIND at 20 percent, The mix is then
component 1, REGRIND, SET=20.0, 20 percent of mix,
component 2, NATURAL, SET= 10, 16.0 percent of mix,
component 3, NATURAL, SET= 40, 64.0 percent of mix.

Components 2 and 3 are still held at a 1 to 4 ratio.

Page 16

ADDITIVE (PERCENT OF ALL NATURALS)

Components designated ADDITIVE will be added as a percentage of all the
NATURALS added together. For example: If component 5 is an ADDITIVE
at 5 percent, Then the above example now looks like this:
component 1, REGRIND, SET=20.0, 20 percent,
component 2, NATURAL, SET= 10, 15.2 percent,
component 3, NATURAL, SET= 40, 61.0 percent,
component 4, ADDITIVE, SET=05.0, 3.8 percent.

The REGRIND is still 20 percent of the MIX.
The NATURALS are still at a RATIO of 1 to 4, although they have been
reduced to make room for the Additive.
The ADDITIVE is 5 percent of the NATURALS added together (5% of 76.2).

WHY do we do it this way? Because this is how most plastic processors
think of these components. REGRIND is generally only added when
available, and then as a limited percentage of the entire mix.
NATURALS are generally blended at a RATIO to one another. ADDITIVES
are most often only intended to be added to the entire NATURAL portion
of the mix, because regrind generally already contains these additives.

ON THE OTHER HAND:

If you prefer to think of your mix as a RATIO OF WEIGHTS, for example,
components 1, 2, 3, 4, and 5 are to be mixed at 100, 50, 5, 20 and 7
pounds respectively, then you may wish to specify ALL components as
NATURALS. In this way these weights may be entered just as listed
here. Components will be dispensed to maintain each at the proper
specified RATIO to the other components.

If you wish to think of all components as PERCENTAGES of THE MIX,
percents that always add up to 100, specify ALL components as REGRIND
and enter the exact percent for each. When ALL components are
REGRINDS, ALL settings must add up to 99 or 100 percent. If they do
not, an error message (REG >100) or (REG <100) will appear.

BUT... WE RECOMMEND that you do it this way:

REGRIND. Use this for all materials that DO NOT require the addition
of the ADDITIVES. For example, your Regrind scrap.

NATURAL. Use this for all materials that are the bulk of the mix.
These will be RATIOED to each other and will automatically constitute
the ENTIRE mix except for the space needed for Regrind and Additives.
A blend of ABS Homo-polymer and Co-polymer or a blend of Styrene Hi
Impact and Crystal are examples of NATURALS ratioed together.

ADDITIVES. Use this for all materials that are added to the NATURALS
only. For example; color, stabilizer, slip agent, etc.

RATE CALIBRATION

YOU DON'T HAVE TO DO THIS.

Software is set to expect STANDARD hardware. If a device meters at a
much lower feed rate then expected, the software will take 10 to 20
cycles to fully adjust. During this time cycles will take longer.

An example of this is a system using a 1/2" auger instead of 1".

If you don't mind letting the system SELF ADJUST, or
your hardware is STANDARD,
then:
+---------------------------------------------------+

SELECTED MODELS - SPECIAL INSTRUCTIONS

This section relates SPECIAL information about a few selected models.

MICRO PULSE

Micro Pulse valves are available on models:
GB/WSB GBM (MICRO Blender) with micro pulse valves.
GB/WSB 122 with optional MICRO PULSE valves.
GB/WSB 131 with optional MICRO PULSE valves.
GB/WSB 140 with optional MICRO PULSE valves.
GB/WSB 240R with optional MICRO PULSE valves.
GB/WSB 440R with optional MICRO PULSE valves.

These models may use our "MICRO PULSE" metering system for Color and
Additive components.

PULSED OUTPUT parameters control the on/off timing, or pulsing, of the
valves. The controlling parameters are the "_PO" component parameters.

When set to 00000, normal slide gate operation occurs.
When set to a value, such as 03030, power will pulse ON then OFF, at 30
interrupt time intervals each way. This ON/OFF cycling will repeat for
the entire dispense time.

When using a MICRO PULSE valve, you must set the related _PO parameter
to 03030.

If overall blender throughput is too low, you may increase the metering
rate of each Micro Pulse device by adjusting the cylinder air flow
control valves for higher flow rate. This causes more rapid movement
of the cylinder, ejecting more pellets per pulse. The drawback is
noisy operation.

We recommend air flow be adjusted for quiet operation, but assuring
full valve movement per on/off cycle. We have already done this. No
further adjustment should be necessary.

The approximate correct air flow adjustments are:
At nose of cylinder, 1.5 full turns out from full closed.
At rear of cylinder, 2.5 full turns out from full closed.
MICRO BLENDER slant valves, adjust by sound.

On fixed hoppers with horizontal micro pulse valves, CLEAN OUT of the
hopper can be accomplished by opening the "clean out" port provided
under the valve. Turn to one side to allow material to drain.

MICRO PULSE - ACCURACY
All MICRO PULSE valves are more accurate if the associated PT parameter
is set to 00090. Read PT parameter in the PARAMETER section.

NORMAL OPERATING SEQUENCE - EACH CYCLE

As the sensor is uncovered, the cycle begins. The target weight of a
complete batch is 18000, 9000, 4000, 2000, 1000, or 400 grams.

REGRINDS are dispensed first, in their order of size, largest dispense
first. After all the Regrind dispenses, the space remaining in the
weigh bin is determined.

NATURALS are dispensed second, in their order of size, each at the
correct ratio to the others. These dispenses are calculated to fill
the bin leaving just enough space for the Additive dispenses. After
all Natural dispense are complete the exact weight of all of the
NATURALS is determined and, based on this actual dispense weight, the
Additive dispenses are now calculated.

ADDITIVES are dispensed last. These dispenses are calculated as a
percentage of all the NATURAL components only.

If any dispense fails to reach the requested weight, the process does
NOT CONTINUE. The ALARM Strobe light flashes, the Beeper sounds, and
the system continues to retry the dispense until the problem is
remedied.

The total batch is then dropped into the mixing chamber for blending
before entering the throat of the process machine.

CONTROLS and OUTPUTS

1. POWER ON switch.

Controls all power to the controller and all outputs. When power is
switched off, battery backed-up RAM preserves all internal totals and
parameters. All other functions are reset for normal start-up when
power is restored.

2. STOP END OF CYCLE / CONTINUE switch

This is the switch that you should use to STOP the system. This switch
is wired in series with the level sensor. Turning it off breaks the
signal to the computer the same as covering the level sensor with
material. This stops the process at the end of a full cycle.

3. IMMEDIATE PAUSE / CONTINUE switch

Causes a computer-controlled immediate pause during a cycle. Dispenses
will stop in mid-dispense if necessary. When switched back to
CONTINUE, the process continues without any error in amounts dispensed.

4. ALL AIR SOLENOID outputs

There is a single 8 pin or 14 pin (or 17 pin) Amphanol plug located on
the front of the control panel. this provides output of all 120 volt
(or 24 volt) signals to drive the air solenoids. These power sources
are transistor driven and are protected by the 1/2 amp panel fuse. See
the wiring diagram section for the correct wiring to each pin.

If more then 7 outputs are to be driven, a 14 pin connector is provided
with outputs for components 8, 9, A, B, and C.
If 24 volt solenoids are used, a 17 pin connector is provided.

5. POWER OUTPUTS (receptacles on panel front)

Each outlet puts out 120 volts (240 outside USA) through internal plug­ in solid state relays rated and fused at 3 amps. These relay outputs
are designed to drive motors or other devices requiring power up to 3
amps each. The LEFT outlet is for component number 5, and the RIGHT
outlet is for component number 6.

6. EIGHT CHARACTER DISPLAY

Displays the accumulated total bin weight, in grams, after each
dispense. The display flashes when an inadequate dispense has occurred
and the dispense is going to be retried. Other information displayed
here includes material usage totals, internal parameters, component
types and settings and various information prompts to assist the
operator.

###### Numbers displayed are the total weight of material, in grams,
in the bin at any time. The weight in the bin is updated only
after an individual dispense is complete. During the dispense
the displayed weight does not change.
P in the left most position indicates unit is in PROGRAM mode.
M indicates unit is in MANUAL mode.
1 R 20.0 indicates: Component 1, REGRIND, SETTING of 20 percent.

Page 25

INVALID indicates:

1. you pressed an incorrect key,

2. you pressed a key for a function that is not active, or

3. you are not in the right mode for this key to operate.
PASSWORD is displayed when you press the "*" key from the normal mode.
Enter "11111" for MANUAL mode or "22222" for PROGRAM mode or
enter your own password number if you have established one.
INSTR -- is displayed when you press the "*" key from the PROGRAM mode.
Enter a 2 digit instruction number for special tasks.
SETTING, OPERATE, TIMED, and CALIBRATE are displayed when the
respective keys are pressed from the manual or program modes.
These displays are followed by pressing a device key; 1
through 9, A, B, C, DUMP, ALARM, MIX, or HOLD.
FLASHING means that retries are occurring because the first dispense
was not enough. Other error conditions also cause flashing.
ROM OK or ROM BAD indicates condition of ROM chip.
See KEYPAD, *25, for explanation.

7. LED LIGHTS

The LED lights in two rows of eight located above the 8 character
display indicate the following:

LEFT COLUMN from top:
1 through 8. Component 1 through 8 is operating.
RIGHT COLUMN from top:
1 through 4. Component 9, A, B, or C is operating.

5. Weigh bin dump valve operating.

6. Mixer motor drive relay operating.

7. Mixer flow control valve is open.

8. Alarm output operating.

NOTE: The silk screening on the panel front next to the leds is
correct for FOUR software but not for TWELVE software.

8. STROBE LIGHT AND BEEPER ALARMS

The Strobe light flashes and the Beeper sounds when a component fails
to meter properly. Alarms begin after a number of retries have
occurred, this number determined by the parameter table (see
Parameters, _AL). These alarms can also indicate an out-of-range TARE
weight. This range is set by the TL and TH parameters; above 100 or
below -50 grams.

9. ALARM SILENCE

This button stops the STROBE and BEEPER ALARMS. The continuation of
the cycle to its proper completion will also stop the alarm. When in
the BATCH mode, this button also serves to start the next batch.

10. LEVEL SENSOR input

The high level sensor in the mixing chamber plugs into this outlet and
signals the controller to start a dispense cycle when it is uncovered.
The sensor must be uncovered for at least 2 seconds before a cycle will
start (see DLY 00488 Parameter). Once a dispense cycle is started,
covering the sensor does not stop it. Operation continues until the
cycle is complete.

Page 26

11. MIXER MOTOR OUTLET

This outlet is energized by the software for a time period following
the dump of the weigh bin. You may adjust this time in the parameter
table (MIX 00010). This time should be just long enough to provide
adequate mixing. Mixing for a longer period may contribute to a static
problem. Also, excessive mixing sometimes causes separation of pellets
of different size and weight. (MIX 00099) will cause the motor to run
for 360 seconds (6 minutes).

12. MIXER MOTOR ON/OFF/TIMED SWITCH

The Mixer ON/OFF/TIMED switch has been removed. To have the mixer
operate continuously, the MIX parameter may be set to 00099. 99 will
instruct the software to run the mixer for 6 minutes after the weigh
bin has emptied at the end of each cycle. This is more then enough
time. This limitation prevents accidentally running the mix motor for
hours on end when the blender is not actually operating.

13. MIXER MOTOR FUSE - 3 amp

This fuse is rated at 3 amps and protects the mixer motor circuit
separately from all other fuses. On 100, 200, and 400 series models,
this fuse protects the mix motor directly. On 900 and 1800 series
models, this circuit operates a 25 amp solid state relay in a separate
box. The mix motor is protected by a "motor starter" switch with a
"heater". This switch must be on for the motor to operate.

14. LOAD CELL input port

The system's two load cells are joined by a common connector that is
plugged into this port.

15. PRINTER output

This is a parallel printer port. A printer plugged in here allows four
types of information to be ported directly to a printer giving the
benefit of a permanent printed record. They are:

1. The totals of the material usage data.
(press VIEW and "*" keys or use the PRT parameter to
AUTOMATICALLY and periodically print these totals.)

2. A listing of the internal parameter table.
(press *77 in the PROGRAM mode.)

3. A printout of information after each cycle including actual
dispensed weights and percentages for every cycle. (press *54 in
the PROGRAM mode, use "*" to set printer flag ON.)

4. A printout of information after the TIME or CALIBRATE routines.
(*54 flag must be on)

Any common parallel printer that you would use with a small PC computer
may be used. Connect using a standard parallel printer cable, (34 pin
parallel Centronix connector to a DB25 IBM compatible connector),
available from us or at any computer store. See: PRINTED OUTPUTS for a

Page 27

detailed explanation of these printouts.

16. COMPUTER input / output

If you choose to gather material usage data automatically and
continuously by computer, then this connector allows for connection to
any IBM PC type computer operating under MS-DOS or WINDOWS.

The COMPUTER port is a DB9 (9 pin) male port. You will need a
specially wired cable from us to connect to the serial port on your
standard PC computer. Your computer operating system must be MS-DOS or
WINDOWS. You will need software from us for communicating with your
Autoweigh Blender. This software allows downloading settings and
retrieval of information and produces reports for those customers who
wish to take advantage of this feature. Either one or many Weigh Scale
Blenders can be connected to one computer. For multiple Weigh Scale
Blender systems, or communication over long distances, an additional

piece of hardware is required. All GB/WSB controllers are fully
programmed to communicate with your computer now or at a later date.

17. PANEL FUSE for duplex receptacle - 3 amp

Fuses the common power wire of the duplex receptacle (the color and
additive outputs). Since these outlets are only turned on one at a
time, each is protected to the full 3 amp rating of the fuse.

18. PANEL FUSE for processor - 1/2 amp

Fuses power to the circuit board power supply which includes all
solenoid outputs and solid state relay outputs.

19. INTERNAL FUSES

An in-line fuse is provided internally to protect the main 120 volt
power cord supply (10) amps. If this fuses blow, an internal short
circuit is indicated and we don't recommend that you try to fix it.
Remember, this unit carries a three year warranty; just send it back.

The MIX MOTOR timed power source and the AUGER FEEDER OUTLETS are
driven by internal solid state plug-in relays. These relays are
located on the circuit board mounted on the inside back surface of the
controller enclosure. A small 5 amp glass fuse is located to the right
of each relay. A spare fuse is also located on the board if
replacement is necessary.

20. THUMBWHEEL SWITCHES

The three sets of THUMBWHEEL switches have no effect unless they are
assigned to a particular output device. Entry of all SETTINGS is done
by using the KEYPAD. However, if you prefer, you may assign up to
three components to the Thumbwheel switches and then use these switches
to set and alter their settings.
Since only three switch sets are available, only 3 components can be
controlled in this manner. All others must use the keypad.
See ENTERING SETTINGS for more information on how to do this.

KEYPAD - DESCRIPTION OF FUNCTIONS

Three (3) operation Modes are available; AUTOMATIC, MANUAL, PROGRAM.

KEYPAD - AUTOMATIC OPERATION MODE

This is the NORMAL operating mode. When power is turned on, the unit
is in this mode. Automatic dispensing occurs ONLY in this mode. The
AUTOMATIC mode is indicated by the ABSENCE of the letter "P" or "M" at
the left end of the display.

Only the VIEW, RECIPE, BATCH, FAST, TAG, CE and EXIT keys are available
in this mode:
These keys operate only BETWEEN cycles or when the PAUSE switch is on.
To stop between cycles, use the "STOP END OF CYCLE" switch.

VIEW DATA: Press to display the CURRENT Date and Time, LAST CLEARED
(VIEW) date and time, and stored material usage data. Total
CYCLES and Material totals are available: (in Pounds, Kilos,
Grams, or Ounces)

Number of CYCLES that have occurred: (D = #####)
TOTAL weight of each component (X): (X = #####)
(only active components are displayed)
Total weight of ALL materials: (T = #####)

Each successive press of the VIEW key displays the next
total. The last displayed line will say (00=CLEAR) for 5
seconds. During this time, you may press 0,0 to clear the
data. Waiting 5 seconds or pressing any other key will exit
the sequence. When the sequence is exited, normal automatic
operation resumes. These totals may be displayed as pounds,
grams, kilograms, or ounces by a selection procedure
explained later (*89).

Press the VIEW key once followed by the "*" key to cause all
information to be sent to the printer (if available). To
then clear the data, press 00 within 5 seconds. Press any
other key or, wait 5 seconds, to continue the process
without clearing the totals.

RECIPE: This key allows you to GET, LOAD, and SAVE RECIPES. To
(RCP) SAVE a recipe you must be in the PROGRAM mode. Recipes are
thumbwheel switch settings. 50 recipes may be stored,
numbered 00 to 50.

This key is NOT FUNCTIONAL unless the third digit in the
"FLG" parameter is set to 1 (FLG xx1xx). To do this, see
the MAINTENANCE section, PARAMETER TABLE, "FLG".

Assuming a proper FLG parameter is set:
In normal Automatic mode: Press RCP key. If a RECIPE is
currently in use then display will flash through the current
stored data:
(RCP --), (1R= xx ), (2N= xx.x), etc., (CE=CLEAR)

Press CE to CLEAR CURRENT RECIPE and return settings to
those previously set. Then press RCP to look at another

Page 30

recipe. Display = (GET --).

If no RECIPE is currently in use, display says (GET --).
Enter 2 digits to retrieve one of 50 recipes.
Display will flash through this recipe data:
(RCP 01), (1R= xx ), (2N= xx.x), etc., (* = LOAD)

Press "*" to LOAD this recipe into memory. Routine will
exit automatically. Press RCP or EXIT to return to the
display (GET --). Press RCP or EXIT again to exit.

To SAVE a RECIPE you must be in the PROGRAM mode.
If you press RCP key again after display of (GET --),
display says (SAVE --). Enter 2 digits, display will say
(SAVING ). The current settings are saved into memory under
the recipe number you have entered.
Routine will EXIT automatically.

EXIT will exit at any time.

To clear a recipe, set all component settings to zero and
save these settings into the recipe location.

BATCH: This key allows you to blend a PRE-SELECTED WEIGHT of
(BTCH) material, and then STOP running and sound the ALARM. The
process may also be programmed to sound the alarm but
continue running. Since each cycle will always blend a full
weigh bin amount, the total amount blended may exceed the
target batch weight by up to one cycle's blend weight.

This key is NOT FUNCTIONAL unless the last digit in the
"FLG" parameter is set to 1 or 2. (xxxx1 or xxxx2). To do
this, see the MAINTENANCE section, PARAMETER TABLE, "FLG".

The ALARM SILENCE button on the side of the controller, is
the ONLY way to CONTINUE OPERATION after a BATCH amount has
been run.

Assuming a proper "FLG" parameter is set:
Press the BTCH key once to view the desired BATCH WEIGHT.
Display will say (BW #####).
BATCH WEIGHT is the amount you wish to dispense before
stopping and/or sounding the alarm.

Press again to view the CURRENT PORTION, of the batch, that
has been dispensed.
Display will say (CP #####).
CURRENT PORTION shows how much of the Batch Weight you have
blended so far.

Press again to view the ACCUMULATED TOTAL weight of all
batches dispensed.
Display will say (AT #####).
ACCUMULATED TOTAL is the sum weight of all batches that have
been blended. This number will continue to grow until it is
manually cleared to zero, or it exceeds its maximum possible
value.
