˛ When welding or brazing in or around this equipment, make sure VENTILATION is

ADEQUATE. PROTECT adjacent materials from flame or sparks by shielding with sheet metal. An approved FIRE EXTINGUISHER should be close at hand and ready for use if needed.

˛ Do not restore power until you remove all tools, test equipment, etc., and the equipment and related components are fully reassembled.

˛ Only PROPERLY TRAINED personnel familiar with the information in this manual should work on this equipment.

We have long recognized the importance of safety and have designed and manufactured our equipment with operator safety as a prime consideration. We expect you, as a user, to abide by the foregoing recommendations in order to make operator safety a reality.

1-3 Responsibility

These machines are constructed for maximum operator safety when used under standard operating conditions and when recommended instructions are followed in the maintenance and operation of the machine.

All personnel engaged in the use of the machines should become familiar with their operation as described in this manual.

Proper operation of the machine promotes safety for the operator and all workers in its vicinity.

Each individual must take responsibility for observing the prescribed safety rules as outlined.

All warning and danger signs must be observed and obeyed. All actual or potential danger areas must be reported to your immediate supervisor.

General Responsibility

No mater who you are, safety is important. Owners, operators and maintenance personnel must realize that every day, safety is a vital part of their jobs.

If your main concern is loss of productivity, remember that production is always affected in a negative way following an accident. The following are some of the ways that accidents can affect your production:

• Loss of a skilled operator (temporarily or permanently)

• Breakdown of shop morale

• Costly damage to equipment

• Downtime

An effective safety program is responsible and economically sound.

Organize a safety committee or group, and hold regular meetings. Promote this group from the management level. Through this group, the safety program can be continually reviewed, maintained, and improved. Keep minutes or a record of the meetings.

Hold daily equipment inspections in addition to regular maintenance checks. You will keep your equipment safe for production and exhibit your commitment to safety.

Please read and use this manual as a guide to equipment safety. This manual contains safety warnings throughout, specific to each function and point of operation.


Operator Responsibility

The operator’s responsibility does not end with efficient production. The operator usually has the most daily contact with the equipment and intimately knows its capabilities and limitations.

Plant and personnel safety is sometimes forgotten in the desire to meet incentive rates, or through a casual attitude toward machinery formed over a period of months or years. Your employer probably has established a set of safety rules in your workplace. Those rules, this manual, or any other safety information will not keep you from being injured while operating your equipment.

Learn and always use safe operation. Cooperate with co-workers to promote safe practices.

Immediately report any potentially dangerous situation to your supervisor or appropriate person.

REMEMBER:

• NEVER place your hands or any part of your body in any dangerous location.

• NEVER operate, service, or adjust the conveying system without appropriate training and first reading and understanding this manual.

• NEVER try to pull material out of the conveying system with your hands while it is running!

• Before you start the conveying system, check the following:

• Remove all tools from the conveying system;

• Be sure no objects (tools, nuts, bolts, clamps, bars) are laying in the area;

• If your conveying system has been inoperative or unattended, check all settings before starting the unit.

• At the beginning of your shift and after breaks, verify that the controls and other auxiliary equipment are functioning properly.

• Keep all safety guards in place and in good repair. NEVER attempt to bypass, modify, or remove safety guards. Such alteration is not only unsafe, but will void the warranty on your equipment.

• When changing control settings to perform a different mode of operation, be sure selector switches are correctly positioned. Locking selector switches should only be adjusted by authorized personnel and the keys removed after setting.

• Report the following occurrences IMMEDIATELY:

• unsafe operation or condition

• unusual conveying system action

• leakage

• improper maintenance

• NEVER stand or sit where you could slip or stumble into the conveying system while working on it.

• DO NOT wear loose clothing or jewelry, which can be caught while working on the conveying system. In addition, cover or tie back long hair.


• Clean the conveying system and surrounding area DAILY, and inspect the machine for loose, missing or broken parts.

• Shut off power to the conveying system when it is not in use. Turn the switch to the

OFF position, or unplug it from the power source.

Maintenance Responsibility

Proper maintenance is essential to safety. If you are a maintenance worker, you must make safety a priority to effectively repair and maintain equipment.

Before removing, adjusting, or replacing parts on a machine, remember to turn off all electric supplies and all accessory equipment at the machine, and disconnect and lockout electrical and pneumatic power. Attach warning tags to the disconnect switch and air shutoff valve.

When you need to perform maintenance or repair work on a conveying system above floor level, use a solid platform or a hydraulic elevator. If there is a permanently installed catwalk on your conveying system, use it. The work platform should have secure footing and a place for tools and parts. DO NOT climb on the conveying system, machines, or work from ladders.

If you need to repair a large component, use appropriate handling equipment. Before you use handling equipment (portable “A” frames, electric boom trucks, fork trucks, overhead cranes) be sure the load does not exceed the capacity of the handling equipment or cause it to become unstable.

Carefully test the condition of lifting cables, chains, ropes, slings, and hooks before using them to lift a load.

Be sure that all non-current carrying parts are correctly connected to earth ground with an electrical conductor that complies with current codes. Install in accordance with national and local codes.

When you have completed the repair or maintenance procedure, check your work and remove your tools, rigging, and handling equipment.

Do not restore power to the conveying system until all persons are clear of the area. DO

NOT start and run the conveying system until you are sure all parts are functioning correctly.

BEFORE you turn the conveying system over to the operator for production, verify all enclosure panels, guards and safety devices are in place and functioning properly.

Reporting a Safety Defect

If you believe that your equipment has a defect that could cause injury, you should immediately discontinue its use and inform the manufacturer.

The principle factors that can result in injury are failure to follow proper operating procedures

(i.e. lockout/tagout), or failure to maintain a clean and safe working environment.


Chapter 2: Functional Description

2-1 Models Covered in This Manual

This manual provides operation, installation, and maintenance instructions for the mechanical components of the conveying system. Model numbers are listed on the serial tag. Make sure you know the model and serial number of your equipment before contacting the manufacturer for parts or service.

Our mechanical components are designed to create vacuum for conveying pelletized, granular, or powder material in a central material handling system. A typical use is as an inplant distribution system for plastic processing plants. Conveying system mechanical components are sized to meet the specific requirements stated by the Customer at the time of purchase.

2-2 General Description

Our central vacuum systems are as varied as the applications that they service. Tubing and equipment furnished in a specially designed system is intended to convey the material(s) specified at the time of purchase at specific rates and distances.

We can advise you on your system capabilities based on system makeup, distance, material, and desired conveying rates.

Pressure drops in the overall system directly affect system capacity, such as number of material line bends, footage of pipe, Y-tubes, T-tubes, etc.

The less distance, flexible hose, and bends you use on material lines, the better. Keep material lines as straight as possible.

Note: Vacuum leaks occurring anywhere in your system reduce capacity.

Basic System Components

A typical conveying system contains the following components:

• Vacuum receiver(s)

• Vacuum pump

• Filter chamber

• Sequence or atmospheric valves

• Controller

• Take-off compartments

• Pickup tubes/wands

• Vacuum and material tubing

Combinations of these components will help you build your system for the application you need.

Pumps & Conveying System Components Chapter 2: Functional Description 11

Basic System Types

Time-Fill Systems

A time-fill system conveys material to an on-line vacuum receiver for a pre-set time period.

When this interval elapses, the controller conveys material to the next on-line vacuum receiver.

Volume-Fill Systems

A volume-fill system conveys material to an on-line vacuum receiver until the material level activates the proximity switch in the vacuum receiver, or a preset time elapses. When either of these conditions occur, the controller conveys material to the next on-line vacuum receiver.

Equipment Cycle

Our bulk material conveying systems are used for automatic pneumatic handling of most free-flowing, dry, pelletized, powder granular materials.

Material characteristics determine the type of equipment needed to properly convey the material.

See Figures 7 and 11 on Pages 25 and 28 for typical system configurations.

2-4 Safety Devices and Interlocks

This section includes information on safety devices and procedures that are inherent to the mechanical components of the conveying system. This manual is not intended to supersede or alter safety standards established by the user of this equipment. Instead, the material contained in this section is recommended to supplement these procedures in order to provide a safer working environment.

At the completion of this section, the operator and maintenance personnel will be able to do the following:

• Identify and locate specific safety devices.

• Understand the proper use of the safety devices provided.

• Describe the function of the safety device.

Safety Circuit Standards

Safety circuits used in industrial systems protect the operator and maintenance personnel from dangerous energy. They also provide a means of locking out or isolating the energy for servicing equipment.

Various agencies have contributed to the establishment of safety standards that apply to the design and manufacture of automated equipment. The Occupational Safety and Health

Administration (OSHA) and the Joint Industrial council (JIC) are just a few of the organizations that have joined with the plastics industry to develop safety standards.

Every effort has been made to incorporate these standards into the design of the mechanical components of the conveying system; however, it is the responsibility of the personnel operating and maintaining the equipment to familiarize themselves with the safety procedures and the proper use of any safety devices.

Fail Safe Operation

If a safety device or circuit should fail, the design must be such that the failure causes a

“Safe” condition. As an example, a safety switch must be a normally open switch. The switch must be held closed with the device it is to protect. If the switch fails, it will go to the open condition, tripping out the safety circuit.

At no time should the safety device fail and allow the operation to continue. For example, if a safety switch is guarding a motor, and the safety switch fails, the motor should not be able to run.

Safety Device Lock-Outs

Some safety devices disconnect electrical energy from a circuit. The safety devices that are used on the mechanical components of the conveying system are primarily concerned with electrical power disconnection and the disabling of moving parts that may need to be accessed during the normal operation of the machines.

Some of the safety devices utilize a manual activator. This is the method of initiating the safety lock out. This may be in the form of a plug, lever or a handle. Within this lockable handle, there may be a location for a padlock. Personnel servicing the equipment should place a padlock in the lockout handle.


In addition to the safety devices listed above, these mechanical components are equipped with a line cord plug. This allows the operator or maintenance personnel to unplug the system from its power source and tag it out. The plug can then be tagged with any number of approved electrical lockout tags available at most electrical supply stores.

WARNING! Always disconnect and lockout all electrical power and pneumatic (i.e. compressed air) sources prior to servicing or cleaning the conveying system. Failure to do so may result in serious injury. No one but the person who installed the lockout may remove it.


Chapter 3: Installation

3-1 Uncrating the Equipment

The mechanical components of the conveying system are shipped mounted on a skid, enclosed in a plastic wrapper, and contained in a cardboard box.

1. Pry the crating away from the skid.

Note: Remove the nails holding the box to the skid and lift the box off carefully; avoiding staples in the 1’ x 4’ wood supports. Cut the steel banding.

2. Use a pry bar to remove the blocks securing the unit to the skid.

3. Lift unit from sides, inserting forklift under the base. The forks must be equidistant from the centerline of the unit and the unit must be balanced on the forks. Lift slowly and only high enough to clear the skid. Use a pry bar if necessary to carefully remove the skid from the unit.

4. Lower slowly.

5. Temporary hardware has been installed to prevent side panels from shifting in transit. Remove hardware.

6. Retain the crating material for reshipping the components in case hidden shipping damage is found.

3-2 Rigging and Placing Mechanical Components

Conveying system installations vary depending on the application: in-plant distribution or rail car unloading, single or multiple material line systems, pellets, or powders. The sections on the following pages are general installation guidelines.

Installing the Pump Package

Place the vacuum pump where you can have easy access to the mechanical components.

Choose a clean, dry place where debris won’t be drawn into the vent valve on top of the blower. If you install the unit outside, you must provide a weather shed to shelter the unit.

1. Level the vacuum pump package. Use shims as needed.

2. Secure the vacuum pump package with appropriately-sized bolts to the floor or mounting platform.

3. Do not twist or warp the pump package base. This can misalign the blower housing and damage the blower.

Vacuum Pump Vent Piping Considerations

Most vacuum pumps are installed with no exhaust venting of the vacuum pump discharge. If your installation requires vacuum pump exhaust venting, follow these guidelines:

• Venting exhaust air from vacuum pumps requires the installation of metal pipe or ducting. Make sure that no more than two inches water column (2” WC or about 0.5

kPa) back pressure is present at the discharge of the vacuum pump silencer.

Note: Improper sizing or ducting of exhaust air voids your warranty!

Pumps & Conveying System Components Chapter 3: Installation 22

• Use piping or ducting at least two (2) diameter sizes larger than the vacuum connection. Overall vent pipe length—horizontal plus vertical—should not exceed 100 feet (about 30 m) and should not include more than three (3) elbows. If you use pipe for venting, make sure that you use Sch. 5 or Sch. 10 pipe with long radius elbows to provide minimum airflow resistance. If you use ducting, make sure you use highpressure ducting with mitered bends—with a minimum of three (3) breaks—for minimum airflow resistance. Make sure all piping connections are properly supported.

• If you are venting pump discharge outdoors, make sure you properly terminate vent piping to prevent pump damage. You can either: a. Install a rain cap, or b. Install the piping so the exhaust faces down and terminates with a screened opening.

Note: If the pump becomes contaminated from rain or airborne particulates, or is damaged by birds, insects, or small animals, your warranty becomes void!

Any variance from these guidelines can cause excessive pump back pressure. Such a condition can drastically affect equipment performance, possibly leading to equipment damage .

Installing the Control Panel

Select a flat, vertical area for mounting the panel. It should be in an area that gives your operator access to the control. Consider how you are running wiring to the vacuum hoppers, the filter chamber, and pump motor starter(s), vacuum switch(es), and vent valve(s). The panel requires a low voltage grounded power drop as listed on the serial tag.

Note: Avoid mounting control panel near material lines.

Installing Material/Vacuum Tubing

Well-designed material/vacuum piping systems provide the best conveying rates.

Vacuum/material piping may be a single material line Y system or multiple material line or a combination of the two systems (See figures 8-10 on page 26 and 27 for examples), depending on the processing floor layout. All systems utilize a common vacuum header line for all stations connected to a pump package; material flow is controlled by sequence T or atmospheric valves operated by the control panel. When installing material/vacuum tubing, take the following into consideration:

• Vacuum leaks anywhere in the system reduce system capacity.

• Keep the number of material tube bends, elbows, Y-tubes, and vacuum T-tubes to a minimum for maximum system capacity.

• Use long radius tube bends on material lines.

• Keep the total length of material conveying flex hose to a minimum. Long flex hose material runs reduce system capacity.

• Vertical material tubing runs should be straight up. Inclined runs can reduce capacity.

• Support tubing about every ten feet with straps, pipe hangers, or brackets.

• Tube joints must be rigid to prevent vacuum or material leaks.


• Cut tube ends square and chamfer edges smooth. Use a fixed band saw or power miter saw when making cuts. You can use a tubing cutter on aluminum tubing, but you need to use a saw with a carbide or diamond-impregnated saw blade when cutting stainless steel. Chamfer outer and inner edge cuts with a die grinder or a hardened rasp file.

• Clean all tubing after cutting and before assembly. Dampen a rag in a non-volatile cleaning solvent, and run it through all tubing and couplers to remove sediment from shipping or cutting. Run a quantity of low-grade material through new lines to remove any remaining sediment, then discard the material immediately.

• Tube ends must butt together inside couplers.

• Tighten tube coupler nuts from the center outward to ensure a tight seal and allow proper contact of the internal grounding strip.

• Each material tubing run must maintain an electrical continuity through the tubing and couplers, from pickup point to vacuum hopper. Grounded flexible hose is recommended.

• If you must cut bends, cut the straight section, leaving enough straight length for complete insertion into a coupler.

• You can attach a quick-change or standard tube coupler to vinyl flex hose by inserting a stub of hard tube into the hose and securing it with a hose clamp. Be sure enough tube extends from the hose to properly install the quick-change or coupler. Make sure that you put clear silicone caulk around adjoining tube seams for exterior bolted couplers.

• If you use stainless flexible material hose, the material flow must be in the direction as indicated by the arrows on the hose. Material direction is not critical with vinyl flex hose.

• Bring all truck fill lines to a central location, such as a silo, unless otherwise specified.

• All rail car manifold Y-tubes must be installed with a ten-degree (10º) downward slant from horizontal on the leg section. Make sure that space between rail car manifold

Y-tubes are fifteen feet (15’/4.5 meters) on center to allow proper alignment between rail car discharge ports and the manifold Y-tubes.

• A plug must be put in the last sequence T valve on the vacuum header to prevent vacuum loss. If atmospheric valves are used, you must terminate the vacuum line at the last atmospheric valve.

Multiple Line System Piping Considerations


• Multiple line systems have separate material lines for each material to allow different types of materials to be conveyed.

• Multiple line systems have separate pickup devices for each vacuum hopper.

• Materials are often loaded from beside the processing machine from gaylords, grinder takeoffs, and storage bin takeoffs.

Figure 7: Typical Multiple Line System Installation

Single Line Y-Tube System Considerations


• Single line Y piping systems use a common material line for all vacuum receivers connected to a pump and are typically used to convey material from a central supply to several stations.

• If you are installing a single line Y system, use Y tubes on the material lines. A Y tube is installed with the branch arm leading to the next station on top and the straight portion that supplies material to the station underneath.

• Connect a short-radius bend to the straight portion as close to the Y as possible.

• You must connect a minimum 2-foot (61 cm) straight length of tube to this short radius bend on the horizontal before the material tubing drops to the receiving point. If possible, incline this tube approximately 1 /

8

” per foot (1 cm per meter).

• On single line Y systems, you must install check valves on material inlet tubes inside vacuum receivers.

• You can install a long- or short-radius bend on the last station, where a Y-tube is not needed.

Figure 8: Recommended Single-Line Y-Tube Installation

Figure 9: Modified Single-Line Y-Tube Installation


Figure 10: Manifold Y-Tube Installation

Figure 11: Typical Single-Line Y-Tube Installation


Material Check Valves in Single Line Y-Tube Systems


• Check valves are a critical feature on single line Y systems. You must have a check valve installed on the material inlet inside the receiver on all vacuum hoppers in single line Y installations.

• Check valves must open when the receiver is being loaded and seal to prevent a vacuum leak when other hoppers are being loaded.

• Vacuum receivers for these systems have a special factory-installed extended material inlet tube to hold the check valve.

• The check valve must not be pressed too far onto the inlet stub to prevent proper sealing.

• The hinge of the check valve should be up to prevent material from being deflected up into the vacuum hopper filter.

• Do not allow vacuum receivers with check valves to be over-filled to a point above the bottom of the check valve. Over-filling prevents the check valve from sealing and creates a vacuum loss. Adjust the conveying time on Time-Fill systems to prevent this from happening.

• Inspect periodically for erosion or wear. Replace as required.

Figure 12: Typical Material Check Valve


Installing FCA, FCK, or FCS Filter Chambers

The filter chamber protects the vacuum pump from damage caused by material carry-over.

Primary system filtration occurs in the filter chamber, not in the vacuum receivers. This reduces maintenance of vacuum receiver filters atop processing machines.

At the end of the conveying cycle to all on-line vacuum receivers, the dump delay cycle occurs. Atmospheric air from the vacuum line is introduced to the filter chamber, equalizing the pressure inside the filter chamber. The material discharge flapper valve falls open and dumps the fines and dust collected during the conveying cycle.

The FCK Filter Chamber utilizes compressed air as a means of filter cleaning. The FCA

Filter Chamber does the same, except utilizes implosion cleaning. The FCS is able to clean the filter by either method.

A compressed air filter cleaning blow back option is available for systems conveying very dusty materials. Consult the Sales Department for more information.

Level and secure the filter chamber near the pump package. Use 3 /

8

” (9 mm) bolts to anchor the filter chamber.

1. Connect the piping between the vacuum inlet valve on the pump package and the tube stub on the filter chamber lid. For easy filter maintenance, install at least three feet (3’ / 1 m) of vinyl flex hose at the end of the run to the filter chamber. The rest may be hard piping as long as it is properly supported.

2. Run vacuum tubing from the tangential inlet tube to the vacuum header line servicing the vacuum hoppers. Turn the inlet tube toward the header. Support the tubing properly and make it vacuum-tight.

Note: Use of a system without a manufacturer-approved filter system installed

on the vacuum air inlet voids the blower warranty!


Figure 13: Filter Chamber Installation, Optional Blowback Controller Shown

Note: Make sure you have all tubing supported at ten (10) foot

(3 meter) intervals.


Installing Vacuum Receivers and Inventory/Vacuum Receivers

Vacuum uses one of three mounting systems: flange, suspension, or silo mounting. Vacuum receivers and inventory vacuum receivers use flange mountings only.

3-3 Compressed Air Connections

Making Pump Compressed Air Connections

Connect the vacuum pump to a minimum of 60 psi to 80 psi (414 kPa to 552 kPa) source of clean, dry, lightly lubricated compressed air. Make the 1 /

8

” NPT (3 mm) connection at the solenoid valve on the pump package.

Your compressed air supply piping should include:

• A shutoff valve for ON/OFF control.

• A pressure regulator with gauge.

• An air filter/lubricator.

3-4 Electrical Connections

Refer to local electrical codes, the schematic, and connection diagrams supplied with this unit and the serial tag for wiring considerations. Run all wiring in conduit if codes require it.

Label all wiring to make any future troubleshooting easier. Make all electrical connections

tight.

Making Pump Power Drop Wiring Connections

WARNING! Be safety conscious! High or low voltage can cause serious or fatal injury.

Installation must be performed by qualified personnel only!! Always disconnect power source before attempting installation or repair.

Pump packages are connected to a three-phase power supply. Bring properly sized power leads in conduit to the contacts in the junction box of each pump package in the system.

Complete the pump wiring connections by performing the following:

• Install a properly-sized fused disconnect switch with lockout on the main lines to each vacuum pump package. This is recommended even for pumps with optional fused disconnects.

• Check the serial tag for voltage and amperage requirements. On 60 Hz units, voltage supplied to the unit must be within plus or minus ten percent (±10%) of the serial tag value; on 50 Hz units, within plus or minus five percent (±5%) of the serial tag value.

Phase imbalance must be less than 2% in accordance with NEMA MG1-14.32.

• Ground the unit for operator safety and equipment protection.

Making Control Panel Power Drop Wiring Connections


Plug the controllers’ power cord into a properly grounded, 3-slot, 115/1/60 VAC or 230/1/60

VAC receptacle as specified on the control panel serial tag and the enclosed controller

Operation and Instruction manual. The control enclosure draws less than 5 amps during normal operation at 115/1/60 VAC.

Caution! The manufacturer recommends that you protect PLC memory by providing the control panel with a dedicated circuit, a true earth ground, and a spike/surge protector.

Connecting the Control Panel to the Pump Package

Note: Consult the specific schematics and Operation & Instruction manual supplied with your controller for your specific application.

• Wire the pump package motor starter coil (M) to the terminal provided in the conveying system control panel enclosure.

• Wire the pump package vacuum relief valve solenoid (SOL A) to the terminal provided in the conveying system control panel enclosure.

• Wire the pump package high vacuum switch (VS) to the terminal located in the conveying system control panel enclosure.

Note: Make sure that the pump motor starter, the vacuum relief valve solenoid, and the blowback solenoid (if supplied) are the same voltage

(24 VDC) as the conveying system control panel control voltage.

Consult the control panel serial tag and the pump package serial tag.

Note: Wire size depends on control voltage, distance, number of vacuum hoppers, and the number of wires in each raceway. Consult a qualified electrician.


3-5 Initial Start-up

Making Startup Checks

Before operating the pumps or any other part of the conveying system, check these details:

1. All components in the system must be installed securely and prepared for operation.

Refer to the instructions supplied with auxiliary equipment for specific checks.

2. Couplers, fittings, attachments, and flexible lines must be attached securely and be vacuum-tight.

3. Electrical and compressed air connections to the pump package, vacuum hoppers, and filter chambers must be complete, safe, and conform to code.

4. The pump package blower gearbox must be filled with oil as specified in the manufacturer’s instructions included in the customer information package.

Caution! Do not overfill the blower gearbox with oil, too much oil damages the blower.

5. If not done already, remove the plastic plug from the silencer air outlet.

WARNING! Keep hands away from the open air inlet to avoid injury!

6. Do not allow any loose parts, tools, or foreign materials in or near the unit and other system components.

7. Check for proper motor rotation, as indicated by an arrow on the pump package motor. Bump-start the pump package with the compressed air disconnected just long enough to verify proper rotation direction.

Note: To change motor rotation:

• Disconnect power at the external disconnect.

• Switch any two incoming power leads on the main power supply.

8. Make sure that filter chamber housings have no leaks; check stretcher clamps for tightness.


Chapter 4: Operation

4-1 Start-up

1. Check the pump for any obstructions that may cause damage.

2. Turn on the compressed air supply to the atmospheric valve on the pump junction box.

3. Switch the disconnect on the pump junction box to the ON position.

4. The pump is now on line and ready for operation.

4-2 Operation Procedures

When you activate the controller, the system energizes and initiates the conveying cycle. The following components energize:

• The vacuum pump motor starter.

• The vacuum pump vent valve.

• The sequencing valve above the first on-line vacuum receiver that requires material.

The vacuum pump draws vacuum to that receiver. When the receiver is full or the time interval elapses, the controller then signals the atmospheric valve above the next on-line receiver requiring material to energize, allowing material to convey to that receiver. The conveying sequence continues to the last on-line vacuum receiver requiring material.

When the time interval for the last receiver elapses or the receiver is full, a new conveying cycle begins at the first on-line vacuum receiver requiring material.

Note: The sequence of events listed above is a generalized description of what occurs when a controller is activated. Consult your specific controller manual for an accurate depiction of these events.

Vacuum Switch (VS) Operation

A high vacuum switch is mounted inside a pump package junction box. It is preset to close at

14” Hg (475 millibars) and is not adjustable. The vacuum switch protects the pump package from motor damage caused by high amperage draw and strain on the blower.

Pumps typically draw a vacuum of less than 5” Hg (170 millibars) only when air is pulled into the system and 8” to 12” Hg (271 to 339 millibars) while conveying.

If system vacuum should reach 14” Hg (475 millibars), the high vacuum switch closes. The pump package tries to clear the line for three seconds, then moves to the next on-line vacuum receiver. The normal conveying cycle continues. If high vacuum keeps occurring, the pump continues with attempts to clear the line.

Refer to your specific controller manual for additional operation information.

Pumps & Conveying System Components Chapter 4: Operation 35

High Vacuum Relief Regulator Operation

A factory-set pressure regulator is installed on the pump package vent valve as a mechanical back-up safety feature. It protects the pump motor from damage during high vacuum conditions if an undetected failure of the vacuum switch should occur. The regulator is set to limit system vacuum to 15” Hg (475 millibars) by allowing the vent valve plunger to shift and vent the pump.

Note: Do not adjust the pressure regulator. Adjusting the pressure regulator voids your warranty.

4-3 Shut-down

To deactivate the conveying system:

1. Turn the disconnect switch at each pump or component to OFF. This will take each pump or component offline.

2. Turn off the compressed air supply to the system.

Note: Consult your specific controller operation and instruction manual for specific shut-down information for your conveying system.

Pumps & Conveying System Components Chapter 5: Maintenance 37

5-2 Preventative Maintenance

Maintaining Pump Packages

Pump packages need periodic maintenance to provide long dependable service. Check these elements regularly:

• Maintain a proper oil level in the blower gearbox. The manufacturer’s brochure

(packed with the pump package) recommends oils, and lists instructions for checking the oil level.

• Pack blower bearings with high temperature ball bearing grease and change the oil to the manufacturer’s recommendations.

• V-belts are sized for maximum life with the pump package blower/motor combination.

Inspect periodically for proper tension, and replace when worn.

Note: V-belts stretch when new. Check belt tension after you have run them

in. At proper belt tension, the belt should deflect downward 1 /

64

” for every one inch span (1 mm every 6.4 cm) from sheave to sheave.

• Keep the pump package area clear of any debris that could be drawn through the vent valve and into the blower while the pump package is idling.

• Torque the motor and blower sheave bolts to 72 ft.-lbs. (98 Nüm).

• Check the moisture traps in the compressed air lines. Drain as needed.

• Check the compressed air lubricator(s) for flow rate and level. Use only 1 or 2 drops

of oil per day when lubricating. Adjust and fill as necessary.

• Inspect the silencer periodically for contamination. Silencer fouling indicates poor filter maintenance at the vacuum hopper or filter chamber. Fines may also be drawn into the silencer through the pump package vent valve during the dump cycle from poor housekeeping near the pump package.

Caution! Make sure you replace a contaminated silencer immediately to avoid blower damage and possible fire hazard.

• Standard pump package TEFC motors do not require lubrication or oiling. Optional motors may have different requirements. Refer to the motor manufacturer’s specification sheet in your Customer Information Packet.

• Keep the control panel and pump package junction boxes securely closed to prevent component contamination.

• Inspect air cylinders and plugers for proper operation.

• Verify that all safety components/circuits are in full operational condition.

Pumps & Conveying System Components Chapter 5: Maintenance 38

Chapter 6: Troubleshooting

6-1 Introduction

The utmost in safety precautions should be observed at all times when working on or around the machine and the electrical components. All normal trouble-shooting must be accomplished with the power off, line fuses removed, and with the machine tagged as out of service.

The use of good quality test equipment cannot be over-emphasized when troubleshooting is indicated. Use a good ammeter that can measure at least twice the AC and DC current that can be encountered for the machine. Be sure that the voltmeter has at least minimum impedance of 5,000 OHMS-per-volt on AC and 20,000 OHMS-per-volt on DC scales.

Popular combination meters, VOM and VTVM can be selected to provide the necessary functions.

Before making haphazard substitutions and repairs when defective electrical components are malfunctioning, we recommend that you check the associated circuitry and assemblies for other defective devices. It is common to replace the obviously damaged component without actually locating the real cause of the trouble. Such hasty substitutions will only destroy the new component. Refer to wiring diagrams and schematics.

Locating mechanical problems, should they occur, is relatively straightforward. When necessary, refer to the parts catalog section.

Note: Refer to specific control panel operation and instruction manual for additional details and Troubleshooting information.

• Worn seals in blower.

Rebuild/replace blower.

• Worn bearings in blower.

Rebuild or replace.

• Loose drive belt(s). Tighten or replace if worn.

Follow the vacuum path from the blower through the filter, piping, valves and material receivers to isolate where the loss occurs.

Filter chamber problem. The vacuum at the filter chamber should be the same as the blower generates. If the vacuum at the filter chamber is adequate, the problem is down line.

• Dirty filter. Clean or replace filter.

• Loose clamps, gaskets or couplers. Tighten or replace.

• Filter chamber discharge flapper not sealing under vacuum. Check for proper operation; clean or repair as needed.

• Check for faulty compressed air blowback solenoid.

Check for voltage signal during cleaning cycle, proper solenoid operation, incorrect wiring, proper compressed air connection, and for worn plunger in valve.


Problem


(Cont’d.)

Possible Cause

Pump package blower problem. Use a cfm/cfh monitoring device to ensure that blower cfm/cfh is to the manufacturer’s specifications.

Consult Service Engineer if problem persists.

(Cont’d.)

Leaks in vacuum lines between valves.

Vacuum leak(s) in vacuum hoppers.

Vacuum leaks in material lines.

Possible Remedy

Vacuum line problem.

Disconnect the vacuum line at the first vacuum hopper and block it off. The vacuum here should equal the vacuum at the blower. Allow a few seconds for vacuum to build.

If the vacuum here is low, disconnect the piping halfway to the first vacuum hopper and check the vacuum there. If proper vacuum exists, the problem is upstream. If not, work backward to isolate the vacuum loss.

• Tighten loose pipe couplers; replace worn gaskets as needed.

• Replace any damaged piping found.

Check for leaks as described in previous steps.

• Replace or re-install worn or misaligned gaskets.

• Hopper discharge flapper not sealing under vacuum.

1) Replace worn or missing gasket.

2) Clean fouled flapper.

3) Check counterweight for proper operation. Repair or adjust as needed.

• Internal check valves missing or damaged. On single line Y systems, internal check valves must be installed in the vacuum hoppers to seal all hoppers not being conveyed to. If the check valves are present and undamaged, they may be pushed too far onto the tube stub to permit a proper seal.

Also, if the hopper is overfilled, the check valve may not seal properly.

Check for leaks as described in previous steps.


Problem


(Cont’d.)

Material is sucked from the filter chamber and through the blower.

Possible Cause

Material take-offs not properly adjusted.

The blower is dead-headed.

Filters in the filter chamber are dislodged, worn, or not seated properly on the gasket.

The material conveyed is not what the system was designed for. Very dusty materials have different conveying needs.

Possible Remedy

Too much air and not enough material or too much material and not enough air. Close takeoff compartment material inlet, slowly open until you hear material surging and slugging. Close material inlet until surging disappears. On most systems, a proper adjustment generates a 6” to

10” Hg (203 to 339 millibars) vacuum.

Check the blower inlet for obstruction.

Replace or repair immediately.

If the exhaust silencer has material in it, replace it to prevent fire hazard.

Consult manufacturer for advice on hardware requirements.

Other service problems or questions can be answered by contacting the Service Department.
