SAFETY WARNINGS
Pinching Hazard:
Air operated slide gates on the bottom of each
receiver are the only items that raise a safety
concern. The air cylinders exert a force of
about 70 pounds on closing. DO NOT reach into this area
when cleaning the receiver, or from below when cleaning the
hopper. DO NOT use your hands to clear obstructions.

2 –Operation
Installation
YOUR SYSTEM consists of:
▪One FILTER/POWER STATION, with central filter; dust collection container; vacuum
blower/motor; 1, 2.5, 5 or 10 HP, all on wheels for portability.
▪One EIGHT STATION CONTROLLER, to be placed on top of the power station, with
outputs to each receiver and the power unit, alarms, and an on/off switch and status
light for each station.
▪Up to eight RECEIVERS, filterless, 10 pound capacity, clear, with level sensor and
vacuum sequencing valve built in.
If your application is "beside the press" using a "pick-up" lance, the following kit is provided for
each receiver.
1 Lance with two 2" hose clamps in box.
12' flexible material hose, 1.5" ID
Each CUSTOMER must supply, or purchase separately:
Vacuum and material line using 1.5", 2", or 2.5" tubing, (steel, aluminum, or PVC), and tees
and elbows as required.
1. RECEIVERS:
Mount receivers over the hopper compartments you wish to load.
Receivers are sized to fit over round openings as large as 10 inches in diameter.
Larger openings require adaptor plates. Openings smaller then 8" diameter must be
enlarged using the drawings provided on the next page.
The 8" x 8" square bolt pattern allows you to select 4 orientations for the receiver.
Select an orientation so the VACUUM line is located best for your installation. The
material inlet line swivels 180 degrees
2. LEVEL SENSOR:
The LEVEL SENSOR is mounted into the base of the receiver. It is placed directly
under the flow of material. If you select another location, be sure that it is not
uncovered before material is completely empty from the receiver.
The sensor LED is ON when COVERED, OFF when UNCOVERED. See
ADJUSTMENTS, page 18, if you suspect it needs adjustment.

3. VACUUM/POWER STATION:
Position power station for easy access to the filter compartment and controller.
Consider the following:
a. 1 HP units:
1 HP units require a STRONG 120 volt power source. DO NOT use an
extension cord, unless it is 12 gauge or better. Be sure the outlet is rated for 20
amps minimum.
On startup, the blower requires a surge of over 40 amps and should be able to
pull this high current to start properly. If supply wire size is not adequate, the
blower will be unable to pull full startup amperage. The higher the initial amp
draw, the faster the motor reaches full speed and, subsequently, the cooler it
runs.
If the blower does not come up to full speed within 6 seconds power supply is not
as strong as it should be.
Slow starting may be OK, depending on the duty cycle of the blower. 120 volt
single phase blower motors have automatic overheat protection and will stop
operating if they become too hot due to an inadequate power supply. If you
experience this problem, read SETUP OPTIONS, Routine 5.
b. 2.5, 5 and 10 HP units:
These units require 3 phase current. 2.5 and 5 HP are 230 or 460 volt. 10 HP is
460 volt only. Typically 3 phase motors reach full speed in a fraction of a
second.
Unless you specified otherwise, we have wired and tested these units for 460
volt, 3 ph. If you rewire them for 230 volts, you will have to change the overload
protection heaters in the motor starter for higher amp draw.
4. CONTROLLER:
Place the controller in the tray provided on top of the Filter/Power station. Secure the
controller with the screw provided in the back of the tray. Hand tighten only.
Plug the CONTROLLER into the 120 volt outlet on the back of the Filter/Power station.
A single controller controls 8 stations. There is a Dual Controller
Option that uses two controllers (Main and Follower) to control up to
a maximum of 16 stations.

Maguire Products, Inc.

MLS Clear Vu
5. SIGNAL/CONTROL LINES - 24 VOLT:
a. Each receiver has a 30-foot signal/control cable. These plug into the back of the
controller. Receivers can be plugged into any one of the eight station "ports".
Connect receivers in a number sequence that makes sense for your installation.
24-volt extension cables are available if required to reach the
controller. Connectors have 7 pins. Earlier units had 4 pins. If your
plugs don't match the receptacles, call us.
a. A short cable comes from the junction box on the back of the Vacuum Power
Station. Plug this into the right side of the controller.
If you have the Dual Controller Option, plug the vacuum station cable
into the Main controller.
6. AIR SUPPLY:
The receivers and the power station both require air pressure to operate. When
mounted on a Weigh Scale Blender, receivers can get their air supply from the extra
"pressure gauge" port on the blender's air pressure regulator.
Each receiver has a tee connector to allow chaining the air supply to another receiver.
Receivers near each other can be chained together.
The Power station also requires an air line. This may be supplied independently or by
running an air line from one of the receivers to the Vacuum Power Station. It is easy to
bundle an air line with one of the 24 volt signal lines that runs from each receiver to the
power station.

LOADING OVER LONGER DISTANCES:
When calculating the EQUIVALENT LENGTH of the material line distance, you must
add for vertical runs, elbows, and flexible tubing. All of these reduce conveying
efficiency.
Equivalent Distance for calculating material lines
1 foot horizontal = 1 equivalent foot
1 foot vertical = 2 equivalent feet
1 foot flex hose = 3 equivalent feet
1 foot radius elbow = 4 equivalent feet
2 foot radius elbow = 8 equivalent feet
Radius for elbows or sweeps should be 8 times the tube diameter. Example: 2"
diameter tube = 16" radius.
Installation Recommendations:
•Use aluminum tubing for vacuum lines and longer material line
runs.
•Minimize use of flexible tubing for material line.
•Use hose clamps to secure all flex tubing
•Use tees as required for vacuum lines
REMEMBER:
Performance is reduced by:
Inadequate diameter line, Longer length lines, Elbows, and
corrugated flex tubing, Restrictions or "neck down" points, Clogged
filters, Vacuum leaks.
LOADING BESIDE THE PRESS:
Twelve foot lengths of flexible hose are provided for beside-the-press conveying of
material. Connect one length to each receiver.
Each line should connect to a pick-up lance in a barrel or gaylord.
Use hose clamps provided to secure the lines.

CHECK OUT PROCEDURE
1. Confirm all air line connections are correct:
With POWER OFF, and AIR PRESSURE connected:
•All receiver slide gates should be OPEN, allowing material to flow out of the receiver.
•The vacuum valve on top of each receiver should be CLOSED, extended, blocking
the vacuum line.
•The vacuum relief valve on top of the POWER UNIT should be OPEN.
2. Turn on main power. Confirm switch light is lit.
3. Turn each station on one at a time, testing each separately.
Switches with receivers CONNECTED will light and blink slowly indicating the sensor is
calling for material. With these stations, the blower will start.
If a single station does not start:
Be sure the sensor is in place.
Be sure the sensor is not covered.
Be sure the signal cord is properly connected.
Adjust sensor if necessary.
Stations NOT connected to receivers will light, but will NOT start the blower.
OPERATION
1. Turn power ON.
2. Turn on each station you wish to load.
The controller will sequence through all stations that are turned on until all hoppers are
full, sensors covered.
The blower motor remains on 10 minutes after all stations are satisfied. The vacuum
relief valve, on top of the filter/power station, allows air to circulate through the vacuum
blower during any "idle" time.
If there is no demand for loading after 10 minutes, the blower shuts down. (This delay
shutdown time is adjustable).
AIR MATERIAL MIX:
The mix of air with material has a dramatic effect on conveying rate.
You should adjust this for each receiver.
Our pick up lances incorporate a disk to regulate air flow.
Our vacuum take-off assemblies (VTA's) allow air adjustment by rotating the probe, or
rotating an air regulator sleeve.
While each station is loading watch the flow of material into the CLEAR-VU receiver.
Adjust air flow for best smooth flow.

RECEIVER LOAD TIME:
As each receiver fills, observe the material level in the receiver. Load time is correct if the
station stops loading when about 75 percent full, or just below the MAGUIRE logo.
If the load time is NOT correct, reset the timer for that station.
To RESET THE TIMER for one station:
1. PRESS and HOLD the "SET LOAD TIME" button AFTER station has started to load.
Load time can be set ONLY while station is loading.
2. RELEASE the button when correct level is reached
The correct time is now set.
For very dusty materials, fill receiver to a LOWER level. This will help keep the filter clear.
LOW fill levels are safer then filling to a level that is too HIGH.
FILTER:
Individual stations contain only a very course screen filter. The filter(s) in the power station
traps all dust before it can reach the vacuum pump.
To check filter:
1. Turn Controller power OFF to stop blower motor.
2. Open the door on the front of the Filter/Power station. Release the lift handle(s). Lower
the filter bucket(s).
3. Remove container. Empty if necessary.
4. Examine the filter. Clean if necessary. If the container has an excessive amount of
material in it, you may be loading a receiver to too high a level. Shorten load times so
receivers do not overfill.
Smaller loads will NOT significantly reduce conveying rate. Stations simply load more
frequently.
For very dusty materials, adjust fill time to fill to a LOWER level. This will help keep the
filter clear.
5. Lift container platform back into place. BE SURE top edge of bucket engages gasket
properly for vacuum.
TOGGLE SWITCH LIGHTS indicate:
SOLID ON: FULL
SLOW BLINKING: LOW
RAPID BLINKING: LOADING
VERY FAST BLINKING: ALARMING, failed to cover sensor last cycle.

TROUBLESHOOTING
If loading is a problem:
1. Be sure: Filter dust collector is "in place" and vacuum tight.
2. Be sure: The material fill "turret" in the top of each receiver is properly in place.
3. Be sure: Air pressure is reaching all the cylinders as well as the Vacuum Blower
Station. Without air pressure, the system will not develop vacuum.
4. Be sure: All signal lines are connected properly at the controller.
5. Be sure: The level sensor, at the bottom of each receiver, is adjusted correctly so it
does not send back a false "covered" signal. See ADJUSTMENTS to
adjust sensor.
6. Check Filter: If the container has an excessive amount of material in it, you may be
loading a receiver to too high a level. Shorten load times so receivers do
not overfill.
Smaller loads do NOT significantly reduce conveying rate.
Stations simply load more frequently.
7. Excessive high vacuum will overheat the blower. A thermal switch is provided in the
exhaust air steam, which trips out at 190F, keeping the air bypass valve open. This
cools the blower, but loading cannot occur during this time. If this happens, check main
filter and receiver screens for blockage.
MECHANICAL ADJUSTMENTS
SENSOR There is a small screw in the rear of the sensor to adjust the sensitivity of the
sensor. Turning it Clockwise (CW) will increase sensitivity. CCW will decrease.
(Some sensors have a plug in front of the adjustment screw, which must first be
removed. The adjusting screw is recessed.)
The LED light is ON when the sensor is COVERED. It is OFF when
UNCOVERED.
To adjust: Make sure sensor is UNCOVERED.
Turn screw inward (CW) until the LED goes ON.
Turn outward slowly (CCW) until it just comes OFF.
Turn 1/4 turn more (CCW).
Now TEST for correct operation.
Cover with hand, LED should light.
Uncover, it should go OFF.
