GETTING STARTED
MACHINE DESCRIPTION
The Weigh Right PMB Series Packaging System automatically dispenses,
your dry products into your bag/jar/carton. The machine can best be described by
examining the different operating features.
THIS MACHINE DESCRIPTION IS A QUICK OVERVIEW TO
HELP YOU BECOME FAMILIAR WITH THE MACHINE AND
HOW IT FUNCTIONS. DETAILED INSTRUCTIONS FOR
OPERATION ARE LOCATED IN OTHER SECTIONS OF THE
MANUAL.
BAG FEEDING
Pre-opened perforated bags on a roll are mounted on a spindle and placed into
brackets at the rear of the machine. The top, or hood of the machine opens up to
expose the bag feeding mechanism. New bag stock is easily loaded into the
machine and threaded through the feeding section during set-up. When the
machine is activated, bags are brought into position for filling by a powered drive
roller that pulls the web of bags from the roll. The operator can vary the stopping
point of the bag opening in the filling and sealing area by changing a control setting
on the machine control panel. Once initial adjustments are made, the machine
feeds each new bag into the same filling position.
SEALING
Seals are made with a steady-heat seal bar mechanism coupled with a pneu-
matically actuated compressive seal pad. A built in safety system ensures pro-
tection for both operator and product when the seal is made. Sealing temperature is
regulated by an accurate controller with an adjustment knob located on the
machine control panel. Each sealed bag is separated from the roll automatically as
part of the seal cycle.

INSTALLATION
Machine installation is accomplished in two steps: Positioning of the Machine in Work
Area and Connection of Air and Power. Follow these steps and the machine will be
ready for loading of your product, adjustment and operation.
MACHINE POSITIONING
The machine should be placed so that it can be accessed easily from all four sides.
The top of the machine has a supply hopper for loading of the product, therefor do not

block the top of the machine. The height of the machine, which can be adjusted with
threaded leveling feet, is usually determined by the method by which the bags are filled.
Manual filling will require the machine to be set at a comfortable height for the operator.
Automatic filling processes because of the way they operate, usually require the
machine to be set at a pre-engineered height, based.on conveyors and other pieces of
equipment.
GETTING STARTED
Height adjustment of the machine is accomplished by loosening (but not
removing) the four leveling feet on either side of the main machine chassis.
Move the machine to the desired height and tighten the lock nuts. Make sure it is level
before tightening the bolts all the way.
THE MACHINE IS TOP HEAVY! DO NOT LOOSEN THE LEVELING FEET
UNTIL PROVISIONS HAVE BEEN MADE TO SUPPORT THE MACHINE WHEN
IT IS OFF OF THE GROUND. MAKE SURE A 1” MINIMUM OF THREAD IS
LEFT IN THE THREADED FRAME POST.
CONNECTION OF AIR AND POWER
The main air filter regulator assembly is attached to the right rear
corner of the machine. The regulator has a
1
A~ NPT port for the
plumbing of the air supply. Connection can be made with either a quick connect
nipple or hard plumbed with a hose fitting.
THE AIR SUPPLY TO THE MACHINE IS FITTED WITH A SUPPLY CUTOFF
DEVICE. IN THE EVENT OF AN EMERGENCY SITUATION THIS DEVICE
WILL BE NECESSARY TO DISCONNECT THE MACHINE FROM THE MAIN
AIR SUPPLY.
The machine comes equipped with a standard 3 prong male 120 volt line cord.
Uncoil the cord and straighten it out. On the front left corner of the machine, locate
the EMERGENCY STOP switch. Make sure the switch is depressed, which is the
off position. Plug the cord into an acceptable outlet as outlined in set up section on
power requirements.
The footswitch assembly comes equipped with a 3 pin cable. Locate the receptacle

GENERAL INTRODUCTION
The Weigh Right is an automatic packaging machine that fills by weight and dispenses your
product into containers or bags.
The product is then fed automatically into a weigh bucket by a 2 speed belt feed system. The
system consists of a bulk (wide) belt and a dribble (narrow) belt. In the bulk mode (below
Setpoint 1) both belts run at independent speeds. The machine should be set up so that 90 to 95
% of the desired weight is fed in the bulk mode. When entering the Setpoints in the weight
indicator keep in mind the amount of product that is “In Suspension.” Product in suspension is a
term that is used for product that has fallen off of the belts but hasn’t yet reached the Weigh Pan
to be weighed. Therefore, when Setpoint 1 is entered you will have to take into account the
amount of product in the air, which will depend on:
1. Density
2. Depth of product
3. Belt Speed
After Setpoint 1 is met the bulk belt slows down to the “bulk slow” setting. This stage will last
until setpoint 3 is met. The dribble belt is set to run for the final stage (set by setpoint 4. After
Setpoint 4 (target weight) is met, the dribble belt stops. It is now ready to be discharged from the
Weigh Pan. The operator controls when the machine discharges with a dump switch.
The electronic weigh scale indicates the weight at any time during the filling process through an
indicator and a digital readout.
The Weigh Right features solid state electronic controls for speed, accuracy, and reliability.

START UP
1. Mount weigh bucket on load cell mounting plate. Verify that weigh bucket opens freely
without obstructions.
2. See that hopper vibrator is plugged in receptacle,(if provided).
3. If all above checks are done, hook up air supply; 80 PSI and electric supply 120/240 VAC 60
cycle single phase; turn on master switch and test feed cycle. To do this, simply load weigh
bucket with product and see that air cylinder/plunger operates to open bucket with
footswitch.
4. Fill supply hopper with product. Turn on feeder switch.
5. Turn on E-stop switch by rotating (push in to turn off), let scales warm up for 15 minutes
then "zero" scales. Turn on master switch.
6. Product will feed to weigh bucket, weigh, then discharge when dump signal is received.
NOTE: Bucket will not dump unless pre-set weight is satisfied.
7. Air operated dump cylinder has adjustable restrictor valves to smooth out opening operation.
8. Located in control panel is a timer to sequence air cylinder. This can be adjusted to hold
bucket open for a longer or shorter period of time.
CONTROLS
1. Manual Dump - Push to empty weigh bucket at end of production to empty machine.
2. Hopper vibrator - Used to vibrate product in supply hopper,(if provided).
3. Master switch - Turns on feeders and begins machine cycle; also resets alarm.
4. Potentiometers - Use to adjust feed rate of feeders.
5. Alarm Reset - Push to reset alarm.
6. Alarm Light - Signifies alarm condition

MODEL BDC SCALE OPERATING INFORMATION
1. We recommend that this (scale) machine be used in an environment free from heavy dust,
vibration or pounding, blowers or industrial fans.
2. The machine is provided with leveling screws; level the machine for best results.
3. Pull emergency-stop switch to power up scales with master switch "off"; let scale warm up
for 15 minutes before "zeroing" each scale for production.
4. The machine will start feeding product when the supply hopper is full. The next step is to
turn on the feeders. This is done by turning the "master" and "feeder" switch to the "on"
position. Turn hopper vibrator on if needed. Open hopper flow gates to desired opening for
unrestricted product flow.
5. The speed of the feed rate determines the discharge rate.
6. The filling speed is also changed by adjusting the feeder potentiometers. The range is from
0-10.0. This unit is equipped with a bulk and dribble feed sequence. The bulk feed setting
should always be higher than the dribble setting. This assures the most accurate filling.
Factory tests were run with average settings noted.
DESCRIPTION OF MACHINE OPERATION
1. Master switch turns on feeders.
2. Scale reaches weight by bulk and dribble.
3. Scale dumps by piston.
4. Bucket dump holds open for approximately .5 seconds.
5. Bucket closes and begins next cycle.

START UP (PRIOR TO OPERATING MACHINE)
A) MAKE SURE ALL GUARDS ARE IN PLACE.
B) While leaving air supply disconnected, plug machine in (120VAC or 220VAC,whichever
applies) and pull the Emergency Stop. Leave Master Switch in the “Off” position. Wait for
Indicator to go through pretest (about 15 seconds).
C) Verify that the Push Plate operates freely without binding or excessive side pressure on
Weigh Pan.
a) Verify that the Indicator is displaying a weight of 0.00. If not push the Zero button.
b) Check to see if the Push Plate is out of adjustment vertically by manually pushing the
Push Plate assembly horizontally through the Weigh Pan. Now by slowly pushing on the
carriage that the Push Plate is attached to, have another person watch the indicator. The
weight shown should NEVER go above approximately 5.00 lbs. If it does back Push Plate
out, loosen the 2 nuts holding the Push Plate in place and raise it slightly, and check
clearance again. Also, note that the Push Plate enters the Weigh Pan without touching
either side excessively.
D) After all the above checks are done, hook up air supply, (90 PSI)
E) Run all conveyor belts and check for proper tracking.
F) Test photoeye level control sensor (located above bulk feed belt) for accurate cut off of infeed
system. Note: This sensor stops the infeed system.
G) Clean entire machine prior to running with actual product.
H) Put product into the Inclined Conveyor. From there, it will rise up and enter the Bulk/Dribble
Belt area. Product will then feed into Weigh Pan, be weighed, and then discharge when
Dump Switch is actuated.
Note: All air-operated cylinders have adjustable flow controls, which have
been factory set, to smooth out operation. The adjustable flow controls are
located either directly on the air cylinder or on the air valve stack located
inside the Junction box.

SCALE OPERATING INFORMATION
A. We recommend that this (scale) machine be used in an environment free from heavy
vibration, pounding blowers or industrial fans. In cold environments, it is important to
leave the machine with the Emergency Stop pulled out and the Master Switch in the
“Off”(the indicator is on).
B. For best results start feeding product when the main bin is approximately ½ full. The next
step is to turn on the Machine. Turning the switches labeled “Emergency Stop “and ”Master”
does this. Note: After the Emergency Stop is released the indicator goes through a warm up
period of about 10 seconds; do not attempt to operate scale during warm-up period)
C. Adjusting the belt feeder potentiometers changes the filling speed. The range is from 0-100.
This unit is equipped with a bulk and dribble feed sequence. The bulk feed setting is usually
higher than the dribble setting. This assures the most accurate and fast filling. Factory tests
were run with average settings noted on a chart in instruction manual.
Note: The speed of the feed rate determines the overall discharge rate.
HOW TO SET DIGITAL SCALE SETTINGS
A) Adjusting the two Setpoints for each scale in the control panel should change the weight or
output. Setpoint #1 determines when the bulk feed turns off. Setpoint #2 determines what the
desired final weight is during the dribble cycle. The final weight or output is obtained by trial
and error. Use digital readout to monitor final weights and then re-adjust. Note: The weight
or output will change if the bulk, dribble speeds are changed.
B) To change Setpoints:
a) Press Setpoint 1 and while LED is flashing you must begin to enter the new setpoint
value.
b) Once the display is set to the proper value, push "Enter".
c) Repeat the above for Setpoint 2.

PRODUCT FLOW CONTROLS
SPEED
The speeds for all conveyors are adjusted by moving dials labeled Incline Belt, Bulk Feed, and
Dribble Feed from 0-100. These potentiometers regulate the motor speeds.
PRODUCT LEVEL CONTROLS
Product in Supply Area behind Product Strike Plate should be kept at a consistent level while
machine is running to avoid starving feed belts. The product level sensors located above the
Incline Belt, and Bulk Feed Belt have to be properly aligned for accurate control. Make sure
photo eye supports do not loosen or rotate causing inaccurate product level sensing.
Note: All photo eyes have an adjustable sensing range. The potentiometer
adjustment is located either on the sensors or on the sensor power supplies.
BELT FEED CONTROL
The control for the belt feeders consists of three speed potentiometer controls; Cascade feed,
Bulk Feed, and Dribble Feed. These potentiometers are enabled by the setpoint function of the
scale indicator
The automatic filling is a three-stage process. The Cascade belt is the upper level vibrator pan
that determines how much product will be delivered to the bulk and dribble belts. There is the
Bulk belt, which rapidly fills the weigh bucket. Finally the Dribble feeding, which operates the
Dribble belt, which is a slower, narrow pan for trickle feeding the bucket to the final desired
weight or count. The speeds of these filling stages can be adjusted using the speed controls
located on the front of the control box. The speeds should be adjusted for maximum filling at
bulk and slower filling near the final weight for fast but precise weighing.
Note: If Setpoint # 1or 2dr is set too close to Setpoint #2, bulk feeding at a fast rate will not give
the weigher adequate time to switch over to the dribble weight and overweights will occur.
Similarly, too fast a dribble rate will not allow the weigher adequate time to close the gate, also
resulting in overweights. Overweights will still be packaged, so it is imperative to observe the
feeding rates when first setting up the machine.

HOW TO CHANGE WEIGHT
1. The weight or output should be changed by adjusting the three setpoints for each scale on the
control panel. Setpoint #1 determines when the bulk gate closes. Setpoint #2-dr is the amount
that is subtracted from Setpoint #2 to determine when Bulk feeding stops. Setpoint #2
determines Dribble feeding stops. The final weight is obtained during the dribble cycle. The
final weight or output is obtained by trial and error. Use digital readout to monitor final
weights and then re-adjust. NOTE: The weight or output will change if the feed rate is
changed.
2. Each setpoint has two values, SP and SP-dr.
A. To change Setpoint #1, press Setpoint #1 and enter the new setpoint value. Once the
display is set to the proper value push "ENTER." Setpoint #1 does not use SP-dr so
press “ENTER” again.
B. To change Setpoint #2, press Setpoint #2 and enter the new setpoint value. Once the
display is set to the proper value push "ENTER." Enter the amount that will be
subtracted from Setpoint #2 (SP-dr) and press “ENTER.”
3. Setpoint values should be set by trial and error. Setpoint #2-dr should be set as small as
possible without over-feeding past the desired rate.
GENERAL MAINTENANCE
1. Unplug machine before performing any maintenance.
2. Keep machine as clean as possible.
3. Periodically check Push Plate air cylinder for wear and smooth operation. Remove water
from air filter system daily. Lubricate air line with U.S.P. mineral oil.
4. Clean scales and belts regularly, with care. Do not apply excessive pressure (more than 5 lbs.)
to Weigh Pan when cleaning.
5. Motors are maintenance free.
6. Keep control panel locked; do not leave open to dust and moisture; cover with plastic during
washdown procedures.
7. Keep pneumatic lubricator reservoir filled with U.S.P. mineral oil. Pressure should be factory
set at about 90 PSI.
8. Check all belts for proper tracking and smooth operation.
9. Check drive chains for tension. There should be about ¼” to ½” deflection with minimal
pressure.

CLEANING
1) Use low-pressure water/washdown solution.
2) Protect electrical controls and sensors from direct water application by covering with a plastic
bag during cleaning.
3) Remember to remove plastic bags from photo eyes after washdown.
4) Some systems feature a “Clean In Place” water spray system to rinse belts; use as needed.
5) Be sure to thoroughly clean under Bulk/Dribble belt. If necessary release tension with red
handle levers and removal without tools; (6 knobs and 1 quick release pin).
6) The Manual Dump Pushbutton will sweep the Weigh Pan clean when the Master Switch is in
the “Off” position.
7) To turn the belts on for cleaning, press the Wash Cycle Pushbutton while the Master Switch
is in the “off” position.

MISCELLANEOUS INFORMATION
1. Keep enclosure tight to prevent dust from getting into electronic controls.
2. NEVER WORK ON OR NEAR MACHINE WHILE POWER SUPPLY IS CONNECTED!

MODEL BDC-1 GENERAL TROUBLESHOOTING INSTRUCTIONS
1. If the machine is malfunctioning or weighing inaccurately, step back and view the operation. You can
usually detect the problem area by looking for the parts that seem to be causing the problem. The
load cell is the most sensitive mechanism on the machine. Extra care should be taken when
performing any maintenance on it.
2. The following is a checklist for trouble shooting the Model BDC-1.NOTE: All of the following
directions can be performed without disassembly.
3. If the filler is not consistently accurate: check to see if the Bulk and Dribble Belts are feeding a
steady stream of product. If feed stream is irregular, check to see that nothing has fallen into the
Supply Area and has blocked or is partially blocking the Supply Area.
4. The Weigh Pan is attached to an electronic scale. It should be treated like a scale. A dirty scale is
more likely to malfunction than a scale that is cleaned regularly. All moving parts (if applicable)
should travel freely without friction.
5. Make sure the Belts are set to the proper control settings. These are marked “Incline Belt, Bulk Feed,
and Dribble Feed." The KBIC Motor controls are individually fused and the most common cause of
problems on this control would be a loose wire connection.
6. For scale control trouble shooting consult Weigh Right.
7. Air valves -- Coils are removable from valve stack individually. Valves feature manual checkpoint.
8. Load cell trouble shooting as per Tedea pamphlet.
9. Main fuses protect Motors and emergency stop relay.
10. An air cylinder is used to sweep the Weigh Pan. This should operate smoothly as long as the pan is
full. This is actuated by the Container Ready Signal and is controlled by the scale controller. An
airflow restrictor mounted on the Rodless Cylinder adjusts the smoothness of this operation. Note:
The scale must reach desired setpoint weight before a dump can occur.
11. The scale can be discharged manually by turning off "Master Switch" and pressing appropriate
“Manual Dump” control panel button; however, make sure container is in place.
12. Re-tighten all electrical terminals and connections; check for loose nuts and bolts on machine.
