ELECTRICAL NOISE CONSIDERATIONS
A major consideration in the installation of a successful system is the problem created by electrical noise.
The following paragraphs provide information to help the user avoid electrical noise problems. Though
many potential problems are presented, few, if any, will be encountered in an actual application using a
suitably installed PLC system, even in a relatively harsh industrial noise environment.
BACKGROUND NOISE
Electrical noise is defined as any unwanted electrical signal which enters the control equipment. Noise
signals cover the entire spectrum of frequencies and may have any wave shape. The largest single
difficulty with noise is that it is not always present. Continuous, or frequent, periodic noises are generally
easy to detect and accommodate. Intermittent noise sources that produce short, high energy bursts at
irregular and widely spaced intervals cause the majority of problems. Noise has a number of different
pathways into the control equipment. It can be conducted through signal or power wiring or it can be
radiated by electromagnetic waves. Conducted noise is typically coupled into the signal or power wiring
either electro-statically or magnetically. Electrostatic coupling occurs through parasitic capacitance
between the noisy line and the signal/power line. This typically would be the case for long wire runs in
the same conduit. Magnetic coupling occurs through parasitic mutual inductances between lines. This
requires high currents or high currents or high rate of change of current as well as significant mutual
inductance, which may result from proximity or wiring. Electromagnetically radiated noise is typically
high frequency (radio waves). The control system and its wiring may act as antennas in picking up noise
signals. This pathway is least likely to present problem levels of noise to a PLC, and its sources are rare
industrial applications. The dominate sources of noise in industry are those devises (and their wiring)
that produce and switch high voltages and currents. Typical examples include large motors, welders, and
contactors that switch heavily inductive loads such as brakes or clutches. Other examples of noise
sources are Triac/SCR motor control and power invertors.
EFFECTS OF ELECTRICAL NOISE
The predominant effect of noise on the system is to cause “soft” failures; that is, failures which do not
damage the system but do cause it to function improperly.
Three main types of soft failures are encountered:
Logic memory alteration.
Register alteration.
Momentary I/O failure.
Logic memory alteration presents the most significant potential problem in that it may, in some cases,
result in improper machine operation. Both register and momentary I/O failures normally result only in
nuisance failures such as operation in the wrong mode, machine glitches or incorrect/non-existent error
messages.

GROUNDING RECOMMENDATIONS
A good grounding system is a major consideration in planning any electrical system. However, it is
essential for proper operation of the electronics that a low-impedance path to earth ground exist. All
filtering devices internal to the PLC require a good earth ground return. The structural ground present in
many industrial environments does not provide an adequate ground return. A supplementary grounding
electrode should be used to reduce the impedance of the earth ground return when direct-wire
connection to the power system is not feasible. As a minimum, a No. 12 AWG stranded copper wire
should be used to connect to the copper grounding electrode. The connection should exhibit very low DC
resistance (0.05 OHM) and low high-frequency impedance (such as copper lugs). Minimum wire sizes,
color coding, and general safety practices should comply with American National Standards and the
National Electrical Code.
Other earth ground sources are not as desirable as a copper ground stake. Green wire earth grounds
(safety grounds) brought into the control system from plants distribution networks tend to be very noisy.
In most plants, the green wire earth ground system is characterized by ground loops, multiple
terminations to different references, and long wire runs adjacent to motor power and other high-power
wiring. Conduit as an earth ground has even more problems. Though many installations use these
ground references successfully, the practice should be avoided.
AC POWER CONSIDERATIONS
Electrical devices should not be operated at the low end of their input power voltage rating for extended
periods of time. When input voltage is low, current input is forced higher to provide the devise with the
power of needs. Additional current means additional heating. When a system is to be installed where
long brownouts are known to occur, the user is advised to supply the PLC with power from a voltage
regulating transformer. Use of this type of transformer will provide normal voltage to the devices and
keep current within normal range.

CHAPTER 1
RECEIPT
230 Series Auger Packer
12 OF 115
The Model 230 Auger Packer consists of the packer
assembly and various items as ordered.
RECEIPT AND INSPECTION
Upon receipt, a check should be made to see that all
items ordered have arrived and are in good condition.
Any damage incurred in shipment should be reported to
the delivering carrier immediately and a claim for the
damage should be filled. If anything is missing or
damaged, contact Choice Bagging Equipment, Ltd. (512352-3694) so that replacement or repair can be initiated.
The Model 230 Auger Packer is shipped with locking
bolts installed to secure and protect the bag post and
weighing assembly during shipment. (See Picture)
ASSEMBLY PROCEDURES
Mark the centerlines of the packer, reference the General Arrangement drawing.
Set the packer into place. It may be desirable to defer final anchoring to the floor until after testing. Place
the packer in the proper location, insuring the frame is level. Check the clearance and fit to the feed
hopper and associated piping prior to securing it firmly to the floor.
It is recommended to install a rubber connection sleeve between bin and
hopper to isolate bin vibrations from packers. (Sleeve not provided with
machine. Recommend 0.25” - 0.375” wall thickness. Sleeve can be
purchased from CBE separately).
The weighing assembly is secured by two shipping bolts that protect the
scale from any damage during shipment. Be sure to remove the shipping
bolts located above the bag chair post before attempting to operate the
machine.
The Model 230 Auger packer uses a load cell scale weighing unit. It is
important to make certain that the load cell and components being
suspended are free from side friction.
Check the alignment of the fill tube to the auger. If adjustments need to
be made to the auger, this is discussed later in Chapter , how to adjust
230 Series Auger Packer
13 OF 115
the auger.
SOLENOIDS / PNEUMATICS
All pneumatic components (air valves & cylinders) are self-lubricating and additional lubricated air is not
required. If lubricated air is used then lubricated air must be used for the life of all the cylinders.
It is recommended that the main high pressure airline supplying the packer be a min size of ½”. Connect
this high-pressure airline to the regulator found on the back side of thee packer. If there are multiple
units, it is recommended to have separate lines feeding each packer. Operating pressure should be 80PSI
It is recommended that an additional water trap (not supplied with machine) be installed up stream of
the packer in the high-pressure airline and the packer. This is to ensure clean dry air is coming to the
machine at all times. We have recommended that the water trap have a self-draining tap.
Any optional equipment ordered when the packer is in the field will be shipped with controls, hose and
fittings. These will need to be installed in the field according to the pneumatic schematic provided. If the
machine was ordered from the factory with option equipment, this will already be done. There is room
for only one addition optional feature to be added in the field at a later date.
Connect all air hoses which were disconnected for shipment. All hoses and related fittings are
correspondingly color coded and size related for ease of re-assembly. All hoses on the packer are: white
for start and black for stop.
Install any attachments which have been shipped loose or separate from the packer. The connection
between the packer inlet the mating supply hopper should be made using a soft flexible connection to
minimize the transmission of vibration.
NOTE: Auger Packers are relatively trouble free as far as basis operation stands. Problems may occur
with the controller or electrical system. If problems occur do not hesitate to call us for information at
(512) 352-3694.
SUPPLY BIN CONNECTIONS
It is recommended that you connect the packer to the supply hopper or surge bin with a rubber
connector. This will minimize or eliminate any vibrations coming from the bin that may influence the
weight.
These collars and bands are available from Choice Bagging Equipment; however they are not supplied
with the equipment. If you would like to order, you may reach our parts department at 512-352-3694.

INSTALLATION
CHAPTER 2
230 Series Auger Packer
15 OF 115
INSTALLATION PROCEDURES
Your system was assembled and tested in our factory. At disassembly, decals with match markings were
applied on matching parts to facilitate installation. Study the General Arrangement and other subassembly drawings to determine the location of items. The center point of the packer inlet must be
located and marked on the floor; accomplish this by suspending a plumb bob from the center of the
mating supply hopper overhead. Verify that this center point on the floor is the proper distance from the
centerline of any associated equipment. Once this match has been verified, the packer can be put into
place and leveled.
NOTE: Do not anchor any equipment to the floor at this time. Equipment should be anchored to the floor
only after a satisfactory alignment and start-up has been achieved. Care must be taken in leveling the
packer at this point. After the packer has been placed in the desired operating location, level the packer
by plumbing the front legs. Any deviation from the plumb between the two legs should be compromised
half-way. This will result in plumb center lines. This step is important for the scale to function properly.
PNEUMATIC CONNECTIONS
Control air for the system should be supplied from a high pressure air source and should be clean and
dry. A minimum of 80 PSIG pressure at approximately 3-5 SCFM is required for proper operation of the
system. Air line connections must be ½” or larger. All air line connections should be made using a flexible
hose to minimize the transmission of vibration. Connect the pneumatic lines using the pneumatic
schematic and the color coded end connections.
ELECTRICAL CONNECTIONS
Control power for the system should be supplied from a clean power source and voltage verified to
ensure proper operation of the system.
NOTE: All wiring is to be accomplished in accordance with national electric code requirements. All
electrical connections should be made using a flexible type conduit to minimize the transmission of
vibration.
CAUTION: When drilling holes for conduit, make sure that absolutely no drill chips enter the panel, as
they may create a short circuit in the control circuits. Check all terminal block connections. Tighten those
which may have come loose during shipment. Connect all sensor and motor wires per the electrical
schematic and the color coded end connections. Terminations from the main electrical control panel to
junction boxes may be required per the electrical schematic. Connect the weighing system’s load cell
cable per the electrical schematic.
NOTE: To avoid the effects of electrical noise on the weighing system, avoid routing load cell cables near
any high voltage source.
230 Series Auger Packer
16 OF 115
FINALIZATION OF INSTALLATION
Check all wiring connections with either an ohm meter or a buzz to verify continuity of all wires.
Check all led proxy switch lights (power).
Wiring and wire runs should be installed as not to interfere with equipment operation and in accordance
with appropriate electrical code.
Make a rotational check of all motors. If phases are reversed, this can be corrected by changing two
power wires in the motor junction box.
All gear reducers are sealed. They are factory sealed to ensure proper operating temperature and
prolonged life.
Check air pressure at all regulators and set per the pneumatic schematic.
(OPTIONAL) Fill all the air lubricator reservoirs if equipped. All cylinders and solenoids don’t require
lubrication).

CHAPTER 3
OPERATION
230 Series Auger Packer
18 OF 115
PRINCIPLE OF OPERATION
An auger feed assembly is the main feature of the Model 230 Auger Packer. The auger housing receives
bulk product from a surge bin and supplies a steady stream into the bag utilizing a flighted auger screw.
High-pressure air (80 PSIG), operates the solenoids and cylinders.
Bags are weighed during the filling operation on a unit consisting of bag support frame and filling tube
mounted on the front of a scale beam. Filled bags are discharged automatically when the machine is
equipped with an automatic discharge bag chair arrangement.
All of the operation activity for each bag filling cycle takes place in a matter of seconds. This packing
speed is important, not only to achieve high production rates and bag accuracy, but also for proper
function of the Model 200 Auger Packer
SEQUENCE OF OPERATION
A representative arrangement of the packer is shown below. It serves to amplify the following
description of a typical; TWO PHASE operational sequence for filling a bag. It should be noted, however,
that a variety of constructions are optional for the Model 200. The sequences as drawn shows the
optional timed powered discharge and timed bag sealer.
PHASE ONE
(Bulk and Dribble)
Phase One is the condition the machine is in at the end of a filling cycle or if the Stop (or scale)
pushbutton is pressed. This is what occurs:
Controller reaches final preset target weight.
The motor drive assembly and agitator stop and the auger reverses.
The material from the product surge bin stops flowing into the packer.
The bag clamp releases the bag.
The bag is discharged from the machine (hand or automatic). Since the material is moved by gravity
flow, the supply of material to the machine is continuous.
Various optional features shown on the schematic operate as follows:
The valve sealer deflates at end of filling cycle - this can be timed to ensure material stabilization in the
bag.
230 Series Auger Packer
19 OF 115
Feed gate closes off the material flow inlet hopper when the goes into the dribble mode (used with
products that flow easy and may flood)
The settler stops if running in continuous mode. (No bulk and dribble)
The powered discharge bag chair tilts to discharge the filled bag at the end of the sealer deflation and
returns.
The speed of these features is controlled with special electrical and pneumatic controls. During Phase
One, the operator also places another empty bag on the filling tube after discharge of the previous bag.
PHASE TWO
Phase Two is the condition the machine is in at the beginning of a filling cycle or if the (Start or Auto
Start) pushbutton is pressed. This is what occurs:
The start PB is pressed.
The bag clamps the empty bag to the fill spout
The bag seal inflates inside the valve of the bag (Optional)
The motor drive (auger) and the agitator start to turn.
A delay and then the settler turns on (Optional)
Material starts to flow into the bag and is weighed simultaneously as it is being filled
Weight reaches first set point.
Settler turns off.
Auger and agitator continue to run but go from fast to slow fill.
Weight reaches second set point (final cutoff).
Phase one note:
If machine is equipped with a bulk only feature the auger will never go into a slow speed. It
will continue at the fast speed all the way thru the entire filling cycle.

CHAPTER 4
COMPONENT
DESCRIPTION
230 Series Auger Packer
21 OF 115
The CBE 230 Consists of the Following Assemblies:
MAIN FRAME ASSEMBLY
The main frame assembly consists of a rigid steel frame and a hinged motor base plate.
The motor base plate has threaded rod adjustment to allow for V-belt tensioning and the hinge side of the
motor base is adjustable to accommodate a wide range of motor sizes.
FRONT POST ASSEMBLY
The front post is the weighing mechanism on which the bag and product is supported during the filling
process. The front post is mounted to the main frame by one S-Type load cells and two spring steel
flexures. The load cell detects changes in the deflection and sends a varying low voltage signal to the
weight controller. The signal is then interpreted by the weight controller to determine when the desired
cut-off weight is reached.
AUGER SCREW DRIVE TUBE ASSEMBLY
The auger screw drive tube assembly unitizes the mounting of the auger support bearing to allow for
quick removal and re-installation of the auger without disturbing the placement of the bearings, sheaves
or drive belts. The delivery auger is supported by two self-centering flange bearings which can be
adjusted to provide proper auger alignment.
AUGER MOTOR
The delivery auger is powered by a 5 H.P. TEFC motor and the agitator is powered by a 1 HP TEFC
MOTOR.. This machine also features a plug reverse action of the auger at the end of each filling cycle. This
feature provides an immediate cut-off of product flow when the desired cut-off weight is reached and
withdraws excessive product from the spout to reduce spillage when the filled bag is removed. This
motor is specially designed to minimize heat generated during frequent start/stop/reverse duty cycles.
BELT DRIVE ASSEMBLY
The belt drive assembly consists of two v type belts and sheaves to transmit power from the auger motor
to the auger. These components were selected for their low rotational inertia, consistent with proper
power transmission from the motor to the auger. A variety of sheave combinations allows selection of
the optimum auger speed for the product being packed.
FEED SYSTEM ASSEMBLY
The feed system consists of; delivery auger, agitator and spout assembly. The auger delivers product
from the auger barrel housing, through the spout, and into the bag being filled. The agitator keeps the

material moving downward toward the feed auger. All augers are balanced and checked before leaving
the factory. Care should be taken to be sure that the auger is not bent or dropped during installation,
cleaning or servicing of the packer. The physical characteristics of products are especially important to
consider when two or more products are to be packaged on the same machine. If the physical
characteristics of the products vary greatly, it may be necessary to have a different auger for each
product for best results. There are two different style spouts that packers can be equipped with: Live
spout and a non-influencing spout. The non-influencing style spout assembly consists of a cone and
integral inner spout which is mounted to the auger barrel housing, and an outer spout which is mounted
to the front post. Since the outer spout is mounted on the front post it is not influenced by the material as
it comes thru the inner spout. The cone and inner spout provide a means to move product from the
auger barrel housing section to the bag, while the outer spout is weighing the product as it is being
discharged into the bag without the material touching the scale (outer spout). A flexible seal is provided
as the connection between the inner and outer spouts to accomplish this and this seal prevents product
from getting between the spouts. Note: If material gets between the two spouts it can cause an influence
to the weighing system. A movable tapered sleeve/cone is also provided to seal the valve during the
filling process to minimize dust. Correct adjustment of the tapered sleeve is important. When the bag
seals onto this tapered sleeve, the internal bag sleeve must be approximately 1” back from the mouth, or
bottom edge, of the spout. Feed systems can be manufactured in a wide variety of sizes, types, finishes,
and materials to fit a particular application.
AUGER BARREL HOUSING
The auger barrel housing receives product from the inlet hopper and houses the rear section of the
delivery auger. The auger barrel can be manufactured in a wide variety of finishes and materials to fit
any application.
AUGER SEAL ASSEMBLY
There are two types of auger seal assemblies which are used to prevent the escape of product from the
rear of the auger barrel. The stuffing box type and air seal type. The most commonly used is the stuffing
box type which utilizes compression shoes and either lamb’s wool or Teflon packing material. Teflon
packing is typically used for food grade applications. The stuffing box is efficient, provided the wool or
Teflon packing is clean. Abrasive particles of product under pressure from the packing glands can cause
severe wear to the auger shaft. For this reason it is recommended that the wool or Teflon be inspected
periodically, and replaced if necessary. The air auger seal utilizes air. Air is used between the seals, and
air is injected between the seals into the auger barrel. Since the air cannot escape past the seals, it slowly
bleeds into the auger barrel. This creates a positive pressure into the auger barrel, therefore preventing
the escape of product. (Regulator should be set at 2-3 PSI)

INLET HOPPER ASSEMBLY
There are several types of inlet hopper assemblies which are used to receive and pre-condition product
from the main supply hopper. There are “V” hoppers, spike and ribbon style agitator hoppers. The “V”
hopper does not contain any agitators and is used to simply transition from the main supply hopper to
the auger barrel. This type of hopper is used for free-flowing products only. The agitator hopper contains
a single agitator to pre-condition the product prior to the auger barrel and delivery auger. This type of
hopper is used for products with slight to moderate bridging characteristics. The agitator is powered by a
shaft mounted gearbox driven by its own motor. All hoppers can be equipped with an access door with
access door safety switch to provide maintenance/clean out access. Inlet hoppers can be manufactured
in a wide variety of finishes and materials to fit a particular application.
HOPPER SEAL ASSEMBLY
There are two types of hopper seal assemblies which are used to prevent the escape of product from the
RA-5 agitator shaft. The waste packing box type and the air seal type are used on the agitator hopper as
well as the auger seal assembly.
BELT GUARD ASSEMBLY
A belt guard assembly is provided to cover the auger drives. These guards should always be fully
installed when the packer is in use. If it is necessary to service the V-belts, the rear guard may be opened,
however there is a safety switch which shuts the packer down totally.
BAG CLAMP ASSEMBLY
There are several types of bag clamp assemblies which may be used to secure the bag during the filling
process. The most common of which are either manual or air operated. Manual valve bag clamps are a
simple over-center clamping devise requiring operator actuation prior to starting the filling cycle. Air
operated clamps, however, are actuated automatically whenever the filling cycle is requested.
INFLATABLE VALVE BAG SEAL
This seal is an inflatable rubber boot that is put on the outer fill spout and inflates and deflates with each
filling cycle. This seal is used primarily for dust control situations.
BAG CHAIR ASSEMBLY
There are several types of bag chair assemblies which may be used to support the bag during the filling
process. The most common of which are either manual or air operated, and can be vibrating or nonvibrating. Manual bag chairs simply support the bag during the filling process and pivot forward to assist
in manual removal of the filled bag. Air operated bag chairs are actuated automatically upon completion
of the filling cycle and are used to discharge the filled bag lengthwise across the take-away conveyor. The
vibratory bag settlers are used to settle and distribute product in the bag during the filling process. Both
230 Series Auger Packer
24 OF 115
models utilize a pair of motor driven counter weights which alternately raise and lower the bag support
pads. In addition to the typical valve bag chairs, open mouth bag and drum/box filling roller racks are
available. These attachments may also be either vibrating or non-vibrating. The vibrating roller racks
utilize a piston type vibrator to settle and distribute product in the bag during the filling process.
DUST COLLECTOR ASSEMBLY
A dust collection shroud and 4” round diameter pick-up connection is provided to help control the dust
emissions which may be generated during the filling process. Ensure that this connection is made using a
flexible type hose to minimize the transmission of vibration.
PNEUMATIC CONTROLS
The main system regulators should be set so that air pressure does not exceed 80 PSI. Plant air systems
are not adequately filtered; therefore a filter/regulator is installed before all components to assure clean
air. This is necessary for smooth-acting, longer lasting components. Moisture collecting in the bottom of
the filter bowl should be bled off as often as necessary. The screens should be cleaned or replaced every
960 hours of operation.
Watch for air leaks around fittings and flexible hoses. Proper pressure and volume are necessary for this
machine to operate correctly. A variety of solenoids and/or air piloted valves are used throughout the
pneumatic system to control the various air operated components as required.
ELECTRICAL CONTROL
The electrical consists of two assemblies: the drive motor starter panel and weight controller. Refer to
the electrical drawings provided in this manual for wiring details. In addition to the drive motor, motor
starter and weight controller, a variety of limit switches, proximity switches, etc. may be used throughout
the system to control various functions as required.

Startup Instructions
& Adjustments
CHAPTER 5
230 Series Auger Packer
27 OF 115
The CBE 230 is an automatic packer. The operator is required to put an empty bag on the filling spout
and press the Start push button after the empty bag is in place. The Start, Stop and E-Stop Push Button
enclosure is located on the front of the packer.
The bag is then filled and weighed automatically, and when equipped with powered bag chair, is
discharged automatically.
If for any reason it is desired to interrupt the filling operation in the middle of a cycle, a red Stop
pushbutton is provided located directly underneath the green Start push button.
Depending on the style controller being used, pressing the Stop once will pause the filling process and
pressing the Stop twice, will abort the fill process.
It is recommended that the following adjustments be made to the packer before any material is delivered
to the receiving hopper:
Make sure all personnel are clear of machine.
Pneumatic Control System
Open manual valve for incoming high-pressure air.
Adjust pressure regulator to 80 PSIG (with power off).
Electrical control system is on.
Voltage coming in matches the sticker on the outside of the box.
Should your packer be equipped with a VFD, please be aware that VFD’s are voltage specific; if voltages
do not match, it will burn the VFD out.
PNEUMATIC ADJUSTMENTS
MAIN LINE PRESSURE
A minimum of 80 PSI should be maintained on the filter regulator at all times during normal operation.
Air pressure can be adjusted by a large hand knob at the top of the regulator. There is also a ¼ turn
needle valve at the bottom of the regulator underneath the water trap bowl. This devise serves to
separate some of the water out of your supply air before allowing it to enter into the bag filler. DRY AIR
IS REQUIRED FOR PROPER OPERATION OF THIS EQUIPMENT. THIS REGULATOR WILL NOT
SEPARATE ALL WATER FROM YOUR AIR SUPPLY. Special care and consideration should be made to
ensure that the compressed air being delivered to the filler is clean and dry. Drain and clean weekly or
230 Series Auger Packer
28 OF 115
daily if necessary depending on the humidity of your environment. If excessive contamination and water
accumulate in the transparent bowl, it should be cleaned more often.
BAG SEAL REGULATOR
Place an empty bag on the filling tube. Press the Start pushbutton.
Adjust THE BAG SEAL REGULATOR PRESSURE TO 3-5 PSIG. This regulator is normally located on the
front leg left side. The gauge on the regulator only goes from 0-15 PSI. From the factory, they are
normally set very low, 1-2 PSI as to prevent damage to the rubber boot if started without a bag on the fill
spout. The seal should expand just enough to secure the valve to the fill spout. Excessive pressure will
damage/crack the valve sleeve and could damage the bag seal.
Caution: Never start the packer without a bag on the fill spout with the bag seal pressure.
Always have an empty bag on the spout. Damage could and will occur to the bag seal if over
inflated without an empty bag on the spout.
POWERED BAG CHAIR FLOW CONTROLS
Flow controls are located right on the cylinder of the bag chair. Take a 3/16” blade screwdriver and
insert into the slot of the flow control. Turning clockwise will slow the motion of the cylinder down.
When adjusting the motion of the cylinder always adjust at the opposite end of the cylinder from where
the action is occurring at.
AIR PURGE STUFFING BOX PRESSURE
On the air purge stuffing box, there are controls. There is a pilot valve and a regulator. The regulated
pressure should be 0-5 PSI. If excessive air is used you will fluidize your product and you may have a
hard time getting it into the bag.
