junction box. Actuators of emergency stop shall be colored RED. The
background immediately around the device actuator shall be colored
YELLOW. The actuator pushbutton-operated device shall be of the palm
or mushroom head type.
CONTROLLED STOP
This is the stopping of machine motion by reducing the electrical command signal to
0 (zero) once the stop signal has been recognized.
HAZARD REVIEW
Electrocution Hazard
Electrocution accidents are most likely to occur during maintenance
of the electrical system or when working on or near exposed high
voltage wiring. This hazard does not exist when the electrical power
has been disconnected, properly locked, and tagged out.
Automatic Start Hazard
This Semi - Automated Pump Stand may be controlled by an
automated system and may start without warning. Failure to properly
disconnect, lockout, and tagout all energy sources of remotely
controlled equipment creates a very hazardous situation and could
cause injury or even death. PLEASE STAY CLEAR AND BE ALERT.

2. Be sure there is enough clearance from overhead obstructions and power lines or
other equipment to move the machine into its working position.
3. Using a forklift, place the seed treater in the desired position on a level surface.
USC highly recommends that the seed treater be set up inside a
building or any covered structure to protect the machine from
weathering.
4. Remove any boxes and cords from the drum of the treater.
5. Install the four provided legs and set up on a level surface, preferably concrete.
When all four legs are mounted in the same pin hole, the seed treater has a slight
slope to allow seed to travel through the machine. The pin holes are approximately
2” apart.
If more slope is desired, the rear legs can be dropped an additional
pin hole.
6. Anchor the seed treater in position to prevent the machine from moving during
operation.

SEED WHEEL
The hopper is equipped with three proximity switches. The top switch controls the inlet
conveyor and the lower switches, located in the seed wheel, control the pump(s).
Refer to H-O-A Screen in section D. See the Proximity Switch Adjustment Guide in
Section F for more in-depth information on these switches.
The Seed Wheel is designed to simplify and increase seed flow calibration accuracy.
A rotating wheel is driven by a variable speed motor, which is set prior to treating the
seed. This is mounted above the atomizer. The wheel consists of 8 identical pockets
approximately 4 inches deep. As it rotates, the wheel captures a certain amount of
seed in each pocket. After the seed is caught, the wheel continues rotation and
dispenses the seed into the atomizer chamber. With the constant turn of the wheel,
there is a consistent amount of seed always sent through the atomizer.
A cup is used to represent a certain percentage of one of the wheels pockets. To
calibrate the seed flow, take a sample of the seed to be treated using the cup and
weigh it (see page 47). By entering the cup weight of the seed sample the system
will automatically adjust the RPM of the Seed Wheel according to the entered target
weight.
The purpose of the seed wheel is to simplify calibration and make seed flow calibration
more accurate. The seed wheel saves time when switching to different seed sizes and
seed types.

ATOMIZER CHAMBER
The atomizer chamber consists of a patented design which disperses treatment evenly
to each seed. A motor drives the atomizer head at approximately 1725 RPM’s. As
treatment is being pumped into the atomizer chamber, it drops into the atomizer head.
The centrifugal force of the spinning head forces the treatment to be sprayed out
through a screen covering in all 360 degrees. Meanwhile, seed flows down out of the
seed wheel and down on top of the distribution cone which disperses the seed down
around the atomizer head. The atomizer can be easily accessed for cleaning and
maintenance by pulling down on the quick release handle and sliding the atomizer
away from the treater body. (see page 69)

ROTATING DRUM
The rotating drum comes in options of 6, 8, and 10 feet and accepts treated seed
through the opening on the hopper end. As seed passes through the length of the
drum it is tumbled, producing accurate and uniform seed coating. The seed then exits
the seed treater out the discharge end of the machine.
Never allow exposure of persons or clothing to the drive shaft, idler
wheels, or the drum during operation. Always have the safety
shields in place during operation.
The time it takes for seed to move through the drum both during and at the end of the
run can be changed by lowering or raising the pins on the legs of the discharge end of
the treater. When the pins are in the same hole on all of the treater legs, the treater
has a natural downward tilt towards the discharge end of the treater. Lowering the pins
on the discharge end’s legs will give the treater more tilt during operation which will
allow seed to travel through the drum at a faster rate. Vice verse, raising those pins
will cause seed to stay in the drum longer.
It is not recommended to lower the discharge end’s pins more than
one hole setting different from the inlet end’s pins. If this is done, a
loss in seed coverage and chemical coating may occur.
On the 6 and 8 foot drum options the LPX automated treater will also come standard
with telescoping fork lift pockets. These pockets can be slid out from underneath the
treater to allow a fork lift to pick up the treater from it’s discharge end.

MIX TANK
The LPX Treater Pump Stand is equipped with a fully modular, touch screen to control
the pump stand. This pump stand will include a 30 or 60 gallon chemical mix tank that
is either of stainless steel or poly construction. This chemical mix tank will have
electric drive agitation that is turned on or off at the pump stand with a manual switch.
The agitator should be running at all times when treatment is present in the mix tank to
keep the chemical mixed and in a suspended state. The tank is equipped with a
shut-off, drain plug, and drain valve located on the bottom. The top of the tank also
includes 3 extra ports which the operator can use to direct fill into the tank (see below).
CALIBRATION TUBE
The LPX Treater Pump Stand is equipped with a
calibration tube which is used to check the liquid flow
rate. The calibration tube measures in ounces, on a
0-340 scale and millimeters on a 0-10000 scale. Manual
valves direct liquid from different areas to keep all liquid
contained. This creates a closed chemical system so
that the operator can manually check the calibration of
the chemical flow rate without handling any of the
chemical.
Page 23
Page 24
LPX AUTOMATED SEED TREATER
PERISTALTIC PUMP HEADS AND MOTOR
The LPX Treater Pump Stand utilizes a variable speed pump motor and special
norprene pump tubing for liquid metering. The pump comes equipped with either
1, 2 or 3 peristaltic pump heads. Liquid will only come into contact with the inside
diameter of the pump tubing and not the pump. This allows for easy cleanup and
less maintenance of the pump.
To open the pump head, lift the lever upward. Place the pump tubing inside the pump
head so it fits inside the notches and above the rollers. Lower the lever back down to
close the pump head, clamping the hose inside the head. Wear or fatiguing of the
tubing within the pump head due to compression is normal. When tubing becomes
worn or chemical rates begin to slow down, open the pump head and move the tubing
to a different position. If the entire piece of tubing becomes worn, simply replace with a
new section. When not using the pump stand for several days or when storing, open
the pump head and remove the tubing to prevent any extra compression.
Pump Head Open Pump Head Closed
If a very low rate is needed, a section of tubing can be removed to force the pump
motor to run at a higher speed. This allows for a more consistent flow rate. When
removing the tubing, uncouple it from the manifold (below, right). If the tubing is
unclamped from the pump head but left coupled in the manifold (below, left), the
pump will suck air and cause flow rates to be very inconsistent.
Page 24
Page 25
LPX AUTOMATED SEED TREATER
FLOW METERS
Each LPX Treater Pump Stand comes with either a volumetric or mass flow meter.
A flow meter is used to perform real-time chemical flow adjustments and monitoring
without the operator having to handle the chemical. The flow meter reading will be
displayed on the HMI touch screen and can be set to read in oz/min or ml/min.

will automatically actuate during normal operation. An internal spring holds the valve
in the recirculation position so that when the valve is not actuated, the chemical will be
directed to flow back to the Mix Tank. When the valve is actuated, the supplied air
pressure will override the spring and move the valve to the PROCESS position.
Chemical flow will then be directed towards the treater’s atomizer chamber.

Proper calibration of the liquid system is critical to achieve a proper granular/chemical
mixture. Use the calibration procedure on page 50 and 51 to determine liquid flow
rate.
Emptying the remaining liquid can be done by using the reverse function on the control
panel. This will pump liquid back into the mix tank. Then drain the remaining liquid
into a suitable container. Clean water should be pumped through the calibration tube
and mix tank when finished.
Always dispose of chemical or diluted chemical according to your
local, state, and federal regulations.
Only you, the operator, can determine the length of time required to
completely rinse all chemical residue from the tank and plumbing
system.

H-O-A (HAND-OFF-AUTO) SCREEN
Hand-Off-Auto controls are provided for most of the automated devices in the system,
and are accessed on this screen.
These H-O-A buttons force the selected component to be energized
(HAND), de-energized (OFF), or automatically energized by the
normal logic sequence (AUTO). The HAND function will cause the
component to operate independent of whatever else the system is
trying to do automatically. These functions should not normally be
used if the automated sequencing is active. Be sure to
understand the impact of energizing or de-energizing a
component with the HAND/OFF settings before using them.
These commands are not a substitute for Lockout/Tagout
procedures when working on or near this machine. Use proper
lockout/tagout procedures to disable the equipment before

SEED FLOW CALIBRATION
The following is a list of steps to use when calibrating the seed wheel. A seed
calibration cup, funnel, stand, and scale are used to calibrate the seed wheel.
1. Set the empty seed calibration cup on the scale and zero out
the weight of the cup.
2. Place the funnel and stand in the seed to be treated or a
separate container (figure 1). This will help to avoid any
unnecessary clean-up while filling and leveling the top of the
seed calibration cup.
3. Place your hand under the bottom of the funnel and fill the
funnel up with seed.
Seed Calibration Cup
4. Place the calibration cup under the funnel stand and remove your hand from the
bottom of the funnel, and allow the cup to be filled. (figure 1)
5. After the cup has been filled, strike off the top of the calibration cup with a straight
edge. (figure 2)
Do not shake the cup.
6. Weigh the sample of seed. (figure 3)
A typical weight of the sample of seed will be anywhere between 2.8 to
4.0 lbs. Anything over or under this range could be caused by not zeroing
out the weight of the cup, or the scale may be set on the wrong units.

FLOW METER CALIBRATION
Due to the composition of some types of chemicals, additional flow meter calibration
may be required. It is recommended that, like other calibration devices, the flow
meter(s) is checked regularly and calibrated when needed. When calibrating the flow
meter(s), each chemical slurry must be checked and adjusted for.
1. To begin the calibration process, fill the
appropriate mix tank with the slurry that is
going to be used for this calibration.
2. Turn the corresponding pump to the hand
position and adjust the flow rate until it reads
about 20 percent on the pump control module
(top). Let the system run in recirculation mode
for 15 minutes. This will remove any air from
the system.
3. Using a stop watch, place the MIX TANK/
CALIBRATION TUBE valve that is located on
top of the mix tank (middle) to the calibration
tube position and begin timing for one minute.
When one minute is up, place the valve back in
the mix tank position. Note the total ounces of
chemical that is in the calibration tube. Also,
note the reading of the flow meter on the main
screen.
4. From the Edit Chemical Screen (bottom) press
the button for the corresponding chemical and
the Chemical Factor Calculator appears. Enter
the calibration tube ounces into the calibration
tube box and the flow meter reading into the
totalizer box. Press the SAVE button and it will
automatically calculate the multiplier and enter
it for that chemical.
5. Exit to the main screen and re-select the
chemical name to set the new multiplier and
ensure proper calibration on this chemical.
The multiplier will not show up on the screen
but will be used by the system for calibration
purposes.
6. Repeat the process as necessary and for each
different chemical slurry used.

4. When the pump’s flow rate has been reached and seed is covering the proximity
sensors inside of the seed wheel, the air actuated 3-way valve will open and allow
liquid to pump up to the atomizer. A moment later (based on the settings in the
utilities screen), the seed wheel will turn on and the seed treating process will
begin.
5. As the seed is being treated. The main screen will display the pounds per minute,
the total pounds, and the liquid flow rate. If the system needs to be stopped for a
moment because of a problem. The PAUSE button can be pressed to halt the
process. When ready to begin again, the CONTINUE button is pressed.
6. When the seed wheel hopper is full the HOPPER FULL indicator light will come on
and the inlet conveyor will shut off. The flow of seed into the treater will begin
again once seed is no longer present at the top proximity sensor in the hopper and
the Inlet Conveyor Delay Restart time defined on the utilities has expired. This is
done to ensure that seed will not overfill the hopper and flow onto the ground.
7. When all seed passes through the seed wheel, the seed wheel will turn off and the
pump will switch to re-circulate. When more seed is fed into the treater, the treating
process will continue.
8. After all seed has been treated the inlet conveyor and the seed wheel will
shutdown automatically. The 3-way valve on the pump stand will switch to
re-circulate. However, the atomizer, drum and outlet conveyor will still be running.
Press the SHUTDOWN button at the bottom of the screen and the shutdown timer
appears and begins to count down the seconds left before complete shutdown.

PROXIMITY SWITCH ADJUSTMENT GUIDE
The proximity switches mounted in the extension ring and the seed wheel detect when
seed is present.
The proximity switch located in the extension ring is used to automatically shut off the
inlet conveyor when the surge hopper is full. This proximity switch is not present on
tower systems.
The proximity switches located in the seed wheel automatically shut off the pump when
all seed has left the hopper.
If the proximity switch is not working properly, this can be caused by wear, dust, or
even moisture. The first step is to clean the lens of the proximity switch. If this does
not solve the problem, the next step would be to adjust the sensitivity of the proximity
switch.
The green light indicates the power status. If it is active the device is powered.
The amber light indicates when seed is being detected. If it is active it detects seed, if
inactive it does not detect seed.
Using the small screwdriver provided inside the control panel, you can adjust the
proximity switch by turning the adjusting screw on the back of the proximity switch.
Turn Clockwise to make the proximity switch more sensitive.
Turn Counterclockwise to make the proximity switch less sensitive.
