SECTION 1 – BLENDER STARTUP
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:
Page 4 SAFETY HAZARDS………………………….. TWO HAZARDS exist on this unit: MIX BLADES and SLIDE VALVES.
Read this short sensible page so no one gets hurt.
Page 6 ASSEMBLY INSTRUCTIONS………………. Very little assembly is required. But you might as well get it right the first
time. ALSO: Pay attention to the section on WIRING.
Page 11 CHECK OUT PROCEDURE………………. This is to see if you did it right. It also will tell if anything was damaged in
shipping.
Page 15 LOAD CELL CALIBRATION……………… We already did this. But shipping or rough handling during assembly
sometimes creates load cell problems. If weight readings are not correct,
you MUST recalibrate the load cells.
Page 16 SETUP OUTPUTS & MATERIAL TYPES... To "TURN ON" a component, it must be 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.
Page 19 RATE CALIBRATION……………………… This is NOT really necessary. But if your system uses non-standard
equipment, you MAY want to do this.
Page 20 SETTINGS and NORMAL OPERATION… 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.
Page 22 SPECIAL FEATURES……………………... Your system can do much more then you may 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
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. Contact Maguire if you require them.
1A. If your unit is to be MACHINE mounted:
For WSB MB, 100, 200, and 400 series models:
Two ways to do this are suggested ON THE NEXT PAGE:
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 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 Weigh Scale Blender frame.
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.

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: (Optional)
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 USA).
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 Compressed Air to the unit.
About 80 psi (5.5 bar) is recommended (40 psi for the Micro Blender). Lubricated air is NOT recommended.
NOTE: Micro Blenders should be set to 40 psi (2.7 bar). The Vertical Valves used in removable hoppers on 100, and 200 series
blenders are more accurate at the lower 60 psi pressure setting.
8. Remove all protective paper from the plastic windows.

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:
•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.
•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 WSB steel
enclosure causing computer trouble.
•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.
•The CONTROLLER and the 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.
•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.
•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.
•We use many internal tooth "STAR" washers in assembling the WSB to ensure good ground between painted
parts. Do not remove them.

Check Out Procedure Diagnostics
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:
MB, 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 USA).

Selecting the Correct Model
Controllers are programmed to control all sizes of Weigh Scale 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:
Blender Model Blender Display

“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:
Model Setup Keypad Sequence:
Press
Display will say: (PASSWORD)
Press
Display will say: (MODEL 220)
Or
Whatever model it is currently set for.
Press
To scroll through all model sizes.
When the model you want is displayed, then:
Press
Wait a few seconds.
Controller 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.
If you should be in any doubt as to which is the correct model you should select please stop and contact your local Maguire
representative who will inform you by return.

SECTION 2 - OPERATION
Load Cell Calibration
NOTE: Displays shown here are in full grams. MB, 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:
Load Cell Zero Calibration Keypad Sequence:
Press
Display will say: (PASSWORD)
Press
Display will say: (P x)
Press
Display will say: (CAL OFF)
Press
Display will say: (CAL ON)
Press
Display will say: (P x)
Press
Display will say: (-- WAIT --)
Followed by: (P 0)
Press
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.
