Safety Instructions Section
Section
A
A
Every year accidents in the work place maim, kill, and injure people. Although it
may be impossible to prevent all accidents, with the right combination of training,
operating practices, safety devices, and operator vigilance, the number of accidents
can be significantly reduced. The purpose of this section is to educate equipment
users about hazards, unsafe practices, and recommended hazard avoidance
techniques. SAFETY WORDS AND SYMBOLS
It is very important that operators and maintenance personnel understand the words
and symbols that are used to communicate safety information. Safety words, their
meaning and format, have been standardized for U.S. manufacturers and published
by the American National Standards Institute (ANSI). The European Community
(E.C.) has adopted a different format based on the International Standards
Organization (I.S.O.) and applicable machinery directives. Both formats are
presented below. Graphic symbols are not standardized, but most manufacturers
will use some variation of the ones seen in this manual.
Indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury.
Indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.
Indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury and/or
property damage.
Provides additional information that the operator needs to be
aware of to avoid a potentially hazardous situation.

LPX AUTOMATED SEED TREATER
LOCKOUT / TAGOUT PROCEDURES
Lockout/Tagout is the placement of a lock/tag on an energy isolating device in
accordance with an established procedure. When taking equipment out of service
to perform maintenance or repair work, always follow the lockout/tagout procedures
as outlined in ANSI Z344.1 and/or OSHA Standard 1910.147. This standard
“requires employers to establish a program and utilize procedures for affixing
appropriate lockout devices or tagout devices to energy isolating devices and to
otherwise disable machines or equipment to prevent unexpected energizing,
start-up, or release of stored energy in order to prevent injury to employees.”
EMERGENCY STOP
There are two Emergency Stop push buttons on the LX Series Seed
Treater, which are located on the main control panel and the treater
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 seed treating system is usually 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.

LPX AUTOMATED SEED TREATER
SUPPLY HOPPER & 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 and Section F: Troubleshooting;
“Proximity Switch Adjustment Guide” 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. From the weight of the seed sample and by also knowing the RPM of the
wheel, you can determine how fast that seed type will pass through the seed treater.
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.

LPX AUTOMATED SEED TREATER
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.

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 supply hopper and down on top
of the distribution cone which disperses
the seed down around the atomizer head.
The atomizer can be easily accessed by
pulling down on the quick release handle
and sliding the atomizer away from the
treater body. (see page 67)

MIX TANK
The USC LPX automated seed treater is equipped with a fully modular, touch screen
controlled 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 control panel.
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 automated pump stand may also be 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. Three-way 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.
FLOW METER
Each LPX automated 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 touch screen controls and can be set to read in oz/min or ml/min.
