The purpose of this section is to alert operating and maintenance personnel to the possible dangers of this type of equipment. Serious injury and/or equipment damage could result from not heeding these safety precautions. 1. Before Operating Equipment A. Any personnel working directly with or on this equipment should read this manual before proceeding with equipment use. B. Electricians should familiarize themselves with the electrical drawings before initial start-up of equipment C. Other appropriate operating and maintenance personnel should familiarize themselves with mechanical layout and general arrangement drawings before tart-up of equipment. D. Determine location of all emergency switches. E. Be sure all guards are in place and observe all warning signs. F. Check oil level in all motors. G. Be sure electrical equipment is free of any accumulation of water. H. Be sure all personnel are clear of operating mechanisms before connecting air. I. Never start equipment without first checking for loose objects, tools and trash. All persons in the immediate area of the equipment should be alerted prior to starting. 2. When Operating Equipment A. Observe extreme caution when switches are turned on. Operation may begin automatically after a time delay. B. Do not open junction boxes or control panels unless you are a qualified electrician. Be sure power is off. Except when electricians are performing maintenance, electrical enclosures and junction boxes should always be securely closed. C. Stop machine and disconnect power supply before servicing or repairing. Maintenance and adjustments must be performed with all power supply disconnected unless otherwise specified in this manual. D. Do not attempt to defeat any safety switches. Serious injury could result. E. While machine control power is on, do not activate limit switches manually. Serious injury and/or machine damage could result. Disable machine before attempting any maintenance or manual testing of components. F. Gear motors will get warm to the touch and should not cause concern for equipment reliability and operation. A temperature rise is normal per new NEMA specifications. G. If additional wire runs are added to any junction box or control panel, wiring practice should be such as to maintain prevailing electrical hazard classification.


H. High-pressure air systems are dangerous. Do not service or troubleshoot systems with air supply on. Be sure to bleed off any trapped air before working on components since it is possible to have high pressures trapped in airlines and cylinders, etc. I. Keep fingers, hands, feet, etc., out of path of pneumatically operated components. J. Safety glasses should be worn in equipment area. K. Follow the safety regulations for your plant. Always use good judgment.


CHAPTER 2

GENERAL INFORMATION


1. Inspection The Taylor Model C, Air-Fill Packer is designed to give years of trouble free service with a minimum of upkeep. A few simple precautions will prolong its life and effectiveness. Upon receiving your packer, un-crate it, stand it up and examine it for shipping damage. If there is damage of consequence, you may file a claim with the freight lines immediately. This is a good time to check all nuts and bolts and wiring and the placement of parts. Using this manual examine the machine for parts and their respective numbers/descriptions. 2. Installation Once you have made the initial inspection, proceed to position the packer under your existing bin. Standard packer height is 72 inches, from floor to top of valve hold down ring. This ring may be removed and adapted to the existing bin. If welding is necessary, the ring must be removed, as welding in place will damage the rubber seal on the inlet valve. You will note that the inlet butterfly valve, when open, extends above the ring. This should present no problem, as it will open into the bin or transition above. Just be sure you do not obstruct its movement. The fit to the bin should be as tight as possible, as some air will escape up through the valve, when machine recharged with material. A loose fit will allow dust to escape Make electrical connections as described in the electrical section. Packer is pre-wired before shipment except service line. Connect the air line to the air filter-regulator on back of packer. Air supply of at least six cu.ft. per minute at 90-100 lbs pressure is supplied by customer. Pressure is not to exceed 125 lbs. Fill air lubricator bowl with ten weight oil and adjust so that one filling of oil will last for at least 60 days of operation or one drop every 15 to 20 bags. It is very important to use the right amount of oil. Too little oil will cause excess discharge and gum to form in the control valves. With all connections made, turn "OFF/ON" switch on and check rotation of blower. If rotation is backwards, interchange L2 and L3 to reverse rotation. 3. Test Running With switch on and the blower running, cycle machine by hand through a few dry runs. Depress the bag actuator switch. The inlet valve and pop off valves should close, causing air to exit out through filling tube. Now, life scale beam "UP" to complete cycle. The inlet valve and pop off valve should open and the bag kicker will extend. Operate through a few cycles. Should any of the above items not operate, "CHECK" the air pressure on all electrical connections, micro switches, and make sure the ground wire is connected. Now place an empty bag on the filling tube and push on the spout until the bag depresses the start switch lever and therefore, shifts the machine to the filling position. Adjust the bag kicker up or down until there is approximately one inch clearance between it and the bottom of the bag. It may be necessary to fill a bag or two to get the adjustment just right; then lock it in place. The bag and the bag kicker should not be in contact during the filling cycle. When bag is filled to desired weight, flow of material will stop and kicker will automatically raise and push filled bag from the filling tube. When all systems check out, proceed to bag material. Check weight of the first bag. Increase weight by moving scale weights back, decrease by moving scale weight forward on the scale beam. Fill and check the first few bags until the proper weight is achieved.


Pivot bearing of scale beam until weight counteracts predetermined selling of scale weight, thus raising beam and activating scale beam limit switch causing pop-off valve to open - immediately and depressurizing hopper. The inlet valve will open and allow the hopper to recharge with material and the bag kicker will eject filled bag from filling tube. Place another bag on the filling tube immediately to repeat cycle. This machine is a relatively simple machine to operate and service. Become familiar with its parts and operation and most problems will be small. 4. Electrical Information Entrance for power supply to starter enclosure of the machine must be three-phase, 220/440 Volt. Your machine comes from the factory pre-wired for 220 Volt, three-phase unless otherwise specified. Motor rotation can be reversed, if necessary, by interchanging L2 and L3 leads of the starter enclosure.


CHAPTER 3

INITIAL SET UP


1. General Information Most scales and IBC units are shipped with spouts and/or load cells removed or unattached to protect them during transit. Packers and check weigh scales are shipped in a locked position for protection. Upon receiving a unit, always completely install it and perform any construction in the area before installing, attaching or unlocking the load cells. All electrical weigh controllers shipped on new units will have been set up, zeroed, and calibrated for that particular unit. Once installed and put in use all the owner-operator need be concerned with is ZERO and GAIN calibration. Although these functions have been preset at the factory, they must always be rechecked and recalibrated before putting the unit into service. ZERO is to be adjusted as required. The GAIN calibration should be checked monthly. 2. Set Up Procedure A. Weight Display - Pre-set on new units. Perform only when installing a new weigh controller or display board. B. Turn Power "ON"

C. Set Decimal Point - Use the small white switches in red molding on the back of the display board. Flip these switches to read 0000 pounds, 000.0 Tenths, 00.00 Hundredths. Normally weights 0 to 10 pounds will be in hundredths, 10 - 200 pounds in tenths, and the larger weights in pounds.

3. Set Meter Range The meter should be set to read just a few pounds higher than the heaviest weight you will be weighing. For example, for one hundred pound weighments, set the meter at one hundred and ten (110) pounds, etc. This will put it in the best range for that job. To set the display meter range, hold the set point switch over, turn the set point know all the way up, use a small screw driver to adjust the display calibration pot to make display read slightly higher than the expected weight. 4. Set Zero This is the one you will use the most often. Use the knob on the outside face of the box to zero the spout, tare off empty bag weight, etc. Inside switches are preset on new units. Use the switches only if you run out of zero on the outside knob, add weight or replace the weigh controller on the main board. To set up: Center the outside zero knob. It will turn ten turns. Turn it all the way up, then back five turns to center. Now look in the lower right hand corner of the main board - you will see two sets of small white switches in red moldings. The set on the "LEFT" controls the ZERO function. The set on the "RIGHT" controls the GAIN function. Flip the LEFT hand switches until you achieve a reading near zero. There is always a combination that will work. Get the closest possible reading, and then make the final zero with the outside knob. 5. Set Gain


This is your weight calibration step and must always be checked when starting a new unit, then monthly. Always perform the calibration step when a new weigh controller or board is changed. A certified scale mechanic may also do this step to certify the scale. After zeroing the unit hang or place a certified scale weight on the spout or platform, observe the weight reading. If it is close, adjust the GAIN via the small pot on the inside near the switches. Use a very small screw driver and adjust carefully. If the weight reading is quite off, flip the small white switches on the RIGHT to bring the reading close to the calibration weight. Then make the final adjustment with the small pot. Be careful and precise in these adjustments. Now remove the weight and readjust the zero. Place the weight back on the scale, readjust the GAIN. It will take three or four adjustments to get the proper calibration. Your unit is now calibrated.


CHAPTER 4

ALTERNATIVE CALIBRATION USING A

WEIGH SCALE


1. General Information It is sometimes more convenient to use a check weigh scale for calibration purposes or as the final check. Using this method you will still go through the first calibration steps to get close, but you may use a pre-weighed bag or box for example, to set the gain switch and gain pot. Now be sure the unit is zeroed, make a weighment, observe the weight reading on the weight controller, place the weighment on check weigh scale, and compare the weights. If the two weights do not agree, "tweak" the gain pot up or down as required. Repeat several weighments until the weight controller reading agrees with the check weight scale and you have now calibrated the unit to the check weight scale. 2. Set Cut-Off Weight This is the point you want the fill cycle to stop at to achieve the desired weight. The cut off point will usually be slightly less than the desired weight as some material will be in transit.

Single Set Point - Hold set point switch over, dial in desired weight with set point knob.

Double Set Point - Hold set point switch over to position one (1), dial in fast fill cut- off point with set point one (1) knob. Hold switch to position two (2) and dial in the final cut-off point with set point two (2) knob.

3. Weigh Trac

Select target weight - dial in exact target weight desired with target knob.

Select early cut-off - (where supplied) - dial in fast fill cut-off point.

Select cut-off - dial in cut-off point. Return selector switch to weight. A little trial and error may be required the first time. Set a weight, run a few weighments, then adjust the cut-off up or down until you get the weighments you want. 4. Simplified Instructions A. Turn POWER "ON" B. Set DECIMAL point 0000 Pounds 000.0 Tenths 00.00 Hundredths C. Set METER RANGE

Hold set point switch

Turn set point knob all the way up

Adjust meter pot to read slightly higher than expected weight. D. Set ZERO

Remove weight

Adjust zero and pot three or four times or until zero and calibration weight read correctly


F. Set CUT-OFF WEIGHT

To achieve desired weight

On Weigh Trac units, set Target and Cut-Off weight

Cut-Off will normally be below Target Weight *Perform steps 2 and 3 on FIRST TIME START UP ONLY. *Adjust ZERO as required. *CHECK CALIBRATION MONTHLY.


CHAPTER 5

ELECTRONIC LOAD CELL INFORMATION


1. Installation and Start-Up Procedures While the load cell and electronic control box are very reliable once installed, extreme care must be used when making the installation. A shock load will destroy a load cell. Therefore, use extreme care when making the installation. NOT COVERED UNDER WARRANTY. 2. General Warnings

DO NOT DROP TOOLS OR OTHER ITEMS ON SPOUT

DO NOT PULL, PUSH OR PRY SPOUT

HOLD THE FRAME TO MOVE THE PACKER

DO NOT LOOSEN OVER TRAVEL NUTS TO RELEASE SPOUT UNTIL ALL OTHER WORK IS COMPLETED.

DO NOT OPERATE THIS EQUIPMENT UNTIL YOU HAVE READ AND UNDERSTOOD THIS MANUAL AND THE BASIC OPERATION OF THE MACHINE.

3. Load Cell Information The load cell and spout have been equalized and adjusted at the factory. DO NOT change the linkage. Observe the over travel adjustment nuts - two on each side of spout. The top nut on ech side is adjusted properly. The bottom nut on each side has been threaded up to lift the spout up enough to take the weight off the load cell and to lock the spout in place for shipment. After installation work is complete, using a wrench, back the two bottom lock nuts down until the load cell linkage is supporting the spout and there is about one-sixteenth (1/16) inch gap between bottom nut and ear. 4. First Time Calibration When calibrating the scale, it is necessary to hold the filled bag on the spout to observe weight reading. To hold bag in place, see the small air valve just back of the meter box. Push down on the bottom to hold the bag in place. Open to eject a bag. Close the valve any time to hold a bag on the spout to observe weight or to stop bagging. 5. Load Cell Trouble Shooting Chart

CHAPTER 11

CYLINDERS


Chapter 12 - Installation Instructions, Trouble Shooting

& Warranty Summary for SL & DR Blowers

1. EXCESS AIR - Bleed it off - DO NOT throttle to reduce flow. When bleeding off excess air

the blower draws LESS power and runs cooler.

2. BOLT IT DOWN - Any unit must be secured against movement prior to start up or testing to

prevent injury or damage.

3. WIRING - Blowers must be wired and protected/fused in accordance with local and national

electrical codes. All integral motor blowers must be grounded to prevent electrical shock.

4. PIPING - All blowers, except SL series, should be piped, muffled and/or filtered prior to start

up. Care must be taken so that no foreign material enters the blower. If foreign material does

enter the blower it could cause internal damage or it may exit at extremely high velocities and

endanger workers.

5. SUPPORT THE PIPING - The blower flanges and nozzles are designed as connectioin points

only and are not designed as support members.

6. PRESSURE/SUCTION MAXIMUMS - The maximum pressure and/or suction as listed on the

model decal should not be exceeded. This can be monitored by means of a pressure or suction

gauge installed in the piping at the blower outlet or inlet. Also if problems do arise the factory

will need to know the operating pressure/suction to properly diagnose the problem.

7. REMOTE DRIVE (MOTORLESS) BLOWERS - Properly designed and installed guards

should be used on all belts, pulleys, couplings, etc. Due to the range of uses and drives guards are

customer/user responsibility.

CAUTION

PLASTIC PIPING SHOULD NOT BE USED ON BLOWERS

LARGER THAN 1 HP THAT ARE OPERATING NEAR

THEIR MAXIMUM PRESSURE SUCTION. BLOWER

HOUSING AND NEARBY PIPING

TEMPERATURES CAN EXCEED 200 DEG. F.

ACCESS BY PERSONNEL TO THE HOUSING OR NEARBY

PIPING SHOULD BE LIMITED, GUARDED

OR MARKED TO PREVENT DANGER OF BURNS.

Chapter 15 - Disassembly & Re-assembly for Inspection or Cleaning


Remove cover bolts and remove cover.

Observe and MAKE NOTES of the impeller orientation (Mark on the IMPELLER -

"THIS SIDE OUT"). Remove the impeller bolt and the impeller. A wheel puller may

be necessary to remove some impellers.

CAREFULLY note the number and/or thickness of shims behind the impeller. Remove

and set in a safe place.

NOTE: IF WORKING ON A DUPLEX (double ended) BLOWER DO NOT MIX

IMPELLERS OR SHIMS FROM END TO END.

Cleaning or inspection can now be completed. Re-assemble the blower by reversing the

above steps.

1. Disassembly for Bearing, Motor or Blower Housing

Remove the cover and impeller by following steps 1 through 4 above EXCEPT the

shimming CANNOT be reused. The impeller must be re-shimmed by following the

re-shimming procedure.

Remove any piping, hoses, flanges, mufflers, etc., that may be attached to the

housing.

Remove the four (4) housing to motor bolts and remove the blower housing from

the motor face.

Remove the heat slinger, if used, from the motor shaft.

The motor or housing can now be repaired as necessary.

2. Bearing Replacement

Great care and proper tools MUST be used when replacing the bearings. Bearings are easily damaged

and short life will result. Arbor presses or equivalent with proper fittings should be used for bearing

removal and installation.

3. Bearing Types and Lubricants

CAUTION

VERIFY THAT THE ELECTRICAL POWER IS "OFF"

AND DISCONNECTED BEFORE DOING ANY

WORK ON THE BLOWER.

CAUTION

VERIFY THAT THE ELECTRICAL POWER IS "OFF"

AND DISCONNECTED BEFORE DOING ANY

WORK ON THE BLOWER.


Bearings for motors 5 HP and smaller are double sealed type lubricated with Rheotemp 500 grease (or

equivalent). Use of other lubricants may give shorter life to bearings.

Bearings for motors 7.5 HP and larger are open, regreaseable type. The only two factory

recommended lubricants are Shell Dolium R or Chevron SRI-2. (Some earlier 7.5 and 10 HP motors

with 1.1875 inch diameter shafts contained sealed bearings and had no grease fittings).

4. Re-assembly and re-shimming

Reassemble the heat slinger, if used, and the housing to the motor face.

Re-Shim the impeller per the re-shimming procedure.

Replace cover, cover bolts, and any piping, hoses, flanges etc.

5. Impeller Shimming Procedure

A. Impeller Shimming and Installation Procedure:

Tools Needed: Machinist's Parallel Bar

Vernier Caliper with depth measuring capability

Feeler gauges or depth gauge

Goal: To center the impeller in the housing cavity.

B. Shimming procedure:

Measure the following: Impeller thickness

Distance from the flange face tot he housing at the

highest point (A).

Distance from the flange face to the motor shaft

shoulder (B).


Measurements (A) and (B) are made by laying the parallel bar across the housing flange face

and measuring to the proper points. Each measurement should be made at three points and the

average of the readings used.

IF (A)=(B): Subtract the impeller thickness from (A) to get the total space remaining. Halve

this number to get the shim thickness required. Install shims of that amount on the motor shaft

IF (B) is greater than (A): The motor shaft shoulder is below the level of the housing. Subtract

(A) from (B) and install that thickness of shimming on the shaft so that (A) = (B). Finish

shimming per (A) = (B) above.

IF (A) is greater than (B): The motor shoulder is above the level of the housing. Subtract (B)

from (A) and make note of the difference. Proceed per (A) = (B) above EXCEPT subtract

from the shimming in (A)=(B) shims equal to the difference just noted. Install the adjusted shim

amount on the shaft.

C. Impeller Installation & Check

With the proper shimming on the motor shaft install the impeller and the impeller bolt &

washer(s). Torque the impeller bolt per the following specifications:

Bolt Size Torque in-lb Torque ft-lb

1/4 - 20 72 ± 3 6 ± .25

5/16 - 18 126 ± 4 10.5 ± .25

CHECK:

As a final check the face clearance from the impeller face to the housing flange face must be

measured. This is done with the feeler gauge and parallel bar or with the depth gauge.

Measurements should be made at the impeller hub outer rim (at the base of the blades). Again

measure at three points and take the average. The clearance should equal one half of the sum

of the housing depth (A) minus the impeller thickness. The centering tolerance combined with

the impeller runout can vary from ± .005 inches on the smallest blowers up to ± 0.12 on the largest

blowers.
